Plan memo management tool for owner

Context

Owner has requested a memo management tool to make it easier to create and manage memos. This is a developer/operator tool (CLI script), not a web feature.

Related docs:

docs/memo-spec.md — memo format, ID scheme, templates
docs/workflow.md — memo routing rules

Request

Plan a memo management tool with the following requirements:

Required feature (MVP)

Memo creation: A script/command that creates a new memo file with:
- Auto-generated hex timestamp ID
- Auto-populated YAML frontmatter (prompting for subject, from, to, tags, reply_to)
- Correct filename (<id>-<kebab-case-subject>.md)
- Placed in the correct recipient's inbox/ directory
- Template body pre-filled based on memo type

Nice-to-have features (if practical)

Inbox listing: Show unread memos for a given role
Thread tracking: Show all memos in a thread (by reply_to chain)
Archive command: Move a memo from inbox to archive
Status overview: Dashboard showing memo counts per role (inbox/archive)

Technical constraints

Must work as a CLI tool (Node.js script or shell script)
Should be runnable with npx or as a package.json script
Must follow the memo spec in docs/memo-spec.md exactly
Should be simple and maintainable

Acceptance criteria

Exact implementation plan for the memo creation feature
List of additional features worth implementing (with effort estimates)
File structure for the tool
How to invoke the tool (CLI interface design)
Rollback approach

Constraints

Must comply with docs/constitution.md (immutable).
Tool must produce memos that are 100% compliant with docs/memo-spec.md.
Keep the implementation minimal. This is a utility, not a product.

Notes

This tool is for developer/operator use, not end-user facing.
Consider using TypeScript since the project already uses it.
The tool should be usable by both human operators and AI agents.

Re: Plan memo management tool for owner

Summary

Complete implementation plan for a memo management CLI tool. The tool is a lightweight TypeScript CLI (scripts/memo.ts) that can be invoked via npx tsx scripts/memo.ts <command>. MVP covers memo creation with auto-generated IDs, YAML frontmatter, correct file placement, and template bodies. Additional features include inbox listing, thread tracking, archive command, and status overview.

Goal

Provide operators and AI agents with a CLI tool that creates and manages memos in full compliance with docs/memo-spec.md, eliminating manual file creation errors and streamlining the memo workflow.

Scope Boundaries

In scope:

CLI tool at scripts/memo.ts with subcommands: create, inbox, thread, archive, status
Auto-generated hex timestamp IDs
YAML frontmatter generation from CLI flags
Template body pre-fill based on memo type
Correct file placement in recipient's inbox/ directory
package.json script entry for convenience
Unit tests for core logic

Out of scope:

Interactive prompts (all input via CLI flags for agent compatibility)
Web UI for memo management
Notification system
Full-text search across memos

B. CLI Interface Design

B.1 Invocation

# Via npx (recommended)
npx tsx scripts/memo.ts <command> [options]

# Via package.json script
npm run memo -- <command> [options]

Add to package.json scripts:

"memo": "tsx scripts/memo.ts"

B.2 Commands

`create` (MVP)

Creates a new memo file in the recipient's inbox.

npx tsx scripts/memo.ts create \
  --subject "Plan memo management tool" \
  --from "project manager" \
  --to "planner" \
  --tags "planning,tooling" \
  --reply-to "19c562b1d90" \
  --template "task"

Flags:

Flag	Required	Default	Description
`--subject` / `-s`	Yes	—	Memo subject (used in frontmatter and filename)
`--from` / `-f`	Yes	—	Sender role name
`--to` / `-t`	Yes	—	Recipient role name
`--tags`	No	`[]`	Comma-separated tag list
`--reply-to` / `-r`	No	`null`	ID of the memo being replied to
`--template`	No	`"task"`	Template type: `task`, `reply`, `research`, `planning`, `implementation`, `review`, `process`

Behavior:

Generate hex timestamp ID via Date.now().toString(16)
Build YAML frontmatter from flags
If --reply-to is set, auto-prefix subject with "Re: " (unless already prefixed), auto-add "reply" tag
Convert subject to kebab-case for filename
Determine target directory: memo/<to-slug>/inbox/
Write file: memo/<to-slug>/inbox/<id>-<kebab-case-subject>.md
Print the created file path to stdout

Output:

Created: memo/planner/inbox/19c562c499c-re-plan-memo-management-tool.md

`inbox` (Nice-to-have)

Lists memos in a role's inbox.

npx tsx scripts/memo.ts inbox --role planner
npx tsx scripts/memo.ts inbox                    # Lists all roles' inboxes

Flags:

Flag	Required	Default	Description
`--role`	No	all	Role to check inbox for

Output:

planner (1 memo):
  19c562b1d90  Plan memo management tool for owner  [planning, tooling, memo]

`thread` (Nice-to-have)

Shows all memos in a reply chain.

npx tsx scripts/memo.ts thread --id 19c562b1d90

Flags:

Flag	Required	Default	Description
`--id`	Yes	—	Any memo ID in the thread

Behavior:

Find the memo with the given ID (scan all memo/ directories)
Follow reply_to chain up to the root memo
Find all memos that have reply_to pointing to any memo in the chain
Display in chronological order

Output:

Thread: "Plan memo management tool for owner"
  19c562b1d90  project manager -> planner  [inbox]   2026-02-13T19:33:00+09:00
  19c562c499c  planner -> project manager  [inbox]   2026-02-13T19:45:00+09:00

`archive` (Nice-to-have)

Moves a memo from inbox to archive.

npx tsx scripts/memo.ts archive --role planner --id 19c562b1d90

Flags:

Flag	Required	Default	Description
`--role`	Yes	—	Role whose inbox to archive from
`--id`	Yes	—	Memo ID to archive

Behavior:

Find file matching memo/<role-slug>/inbox/<id>-*.md
Move (rename) to memo/<role-slug>/archive/<id>-*.md
Print confirmation

Output:

Archived: memo/planner/inbox/19c562b1d90-plan-memo-management-tool.md -> memo/planner/archive/19c562b1d90-plan-memo-management-tool.md

D. Implementation Order for `builder`

Step 1: Add `tsx` dev dependency

tsx is needed to run TypeScript scripts directly. Add to package.json devDependencies:

"tsx": "4.19.4"

Run npm install.

Step 2: Add `memo` script to `package.json`

"memo": "tsx scripts/memo.ts"

Step 3: Create type definitions

Create scripts/memo/types.ts with exact content from section C.1.

Step 4: Create core modules

Create files in this order (no inter-dependencies within this group except types.ts):

scripts/memo/core/id.ts (C.2)
scripts/memo/core/paths.ts (C.3)
scripts/memo/core/frontmatter.ts (C.4)
scripts/memo/core/templates.ts (C.5)
scripts/memo/core/parser.ts (C.6)

Step 5: Create commands

Create in order:

scripts/memo/commands/create.ts (C.7) — MVP
scripts/memo/commands/inbox.ts (C.8)
scripts/memo/commands/archive.ts (C.9)
scripts/memo/commands/thread.ts (C.10)
scripts/memo/commands/status.ts (C.11)

Step 6: Create CLI entry point

Create scripts/memo.ts with exact content from section C.12.

Step 7: Create unit tests

Create scripts/memo/__tests__/ directory and add tests:

`scripts/memo/tests/id.test.ts`

import { expect, test } from "vitest";
import { generateMemoId } from "../core/id.js";

test("generateMemoId returns a hex string", () => {
  const id = generateMemoId();
  expect(id).toMatch(/^[0-9a-f]+$/);
});

test("generateMemoId returns a string that decodes to a recent timestamp", () => {
  const before = Date.now();
  const id = generateMemoId();
  const after = Date.now();
  const decoded = parseInt(id, 16);
  expect(decoded).toBeGreaterThanOrEqual(before);
  expect(decoded).toBeLessThanOrEqual(after);
});

`scripts/memo/tests/frontmatter.test.ts`

import { expect, test } from "vitest";
import { formatTimestamp, serializeFrontmatter } from "../core/frontmatter.js";
import type { MemoFrontmatter } from "../types.js";

test("formatTimestamp returns ISO-8601 with timezone", () => {
  const ts = formatTimestamp(new Date("2026-02-13T19:33:00+09:00"));
  expect(ts).toMatch(/^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}[+-]\d{2}:\d{2}$/);
});

test("serializeFrontmatter produces valid YAML frontmatter", () => {
  const fm: MemoFrontmatter = {
    id: "abc123",
    subject: "Test memo",
    from: "planner",
    to: "builder",
    created_at: "2026-02-13T19:33:00+09:00",
    tags: ["planning", "test"],
    reply_to: null,
  };

  const result = serializeFrontmatter(fm);
  expect(result).toContain("---");
  expect(result).toContain('id: "abc123"');
  expect(result).toContain('subject: "Test memo"');
  expect(result).toContain("reply_to: null");
  expect(result).toContain("  - planning");
  expect(result).toContain("  - test");
});

test("serializeFrontmatter handles reply_to with value", () => {
  const fm: MemoFrontmatter = {
    id: "abc123",
    subject: "Re: Test memo",
    from: "planner",
    to: "builder",
    created_at: "2026-02-13T19:33:00+09:00",
    tags: ["reply"],
    reply_to: "original123",
  };

  const result = serializeFrontmatter(fm);
  expect(result).toContain('reply_to: "original123"');
});

test("serializeFrontmatter handles empty tags", () => {
  const fm: MemoFrontmatter = {
    id: "abc123",
    subject: "Test",
    from: "planner",
    to: "builder",
    created_at: "2026-02-13T19:33:00+09:00",
    tags: [],
    reply_to: null,
  };

  const result = serializeFrontmatter(fm);
  expect(result).toContain("tags: []");
});

`scripts/memo/tests/paths.test.ts`

import { expect, test } from "vitest";
import { resolveRoleSlug, toKebabCase } from "../core/paths.js";

test("resolveRoleSlug maps display names to slugs", () => {
  expect(resolveRoleSlug("project manager")).toBe("project-manager");
  expect(resolveRoleSlug("process engineer")).toBe("process-engineer");
  expect(resolveRoleSlug("planner")).toBe("planner");
});

test("resolveRoleSlug throws for unknown role", () => {
  expect(() => resolveRoleSlug("unknown")).toThrow('Unknown role: "unknown"');
});

test("toKebabCase converts subjects to kebab-case", () => {
  expect(toKebabCase("Plan memo management tool")).toBe(
    "plan-memo-management-tool",
  );
  expect(toKebabCase("Re: Original Subject")).toBe("re-original-subject");
});

test("toKebabCase truncates to 60 characters", () => {
  const long = "a".repeat(100);
  expect(toKebabCase(long).length).toBeLessThanOrEqual(60);
});

`scripts/memo/tests/templates.test.ts`

import { expect, test } from "vitest";
import { getTemplate } from "../core/templates.js";

test("getTemplate returns content for all template types", () => {
  const types = [
    "task",
    "reply",
    "research",
    "planning",
    "implementation",
    "review",
    "process",
  ] as const;

  for (const type of types) {
    const template = getTemplate(type);
    expect(template.length).toBeGreaterThan(0);
    expect(template).toContain("##");
  }
});

test("task template includes required sections", () => {
  const t = getTemplate("task");
  expect(t).toContain("## Context");
  expect(t).toContain("## Request");
  expect(t).toContain("## Acceptance criteria");
  expect(t).toContain("## Constraints");
  expect(t).toContain("constitution.md");
});

test("reply template includes required sections", () => {
  const t = getTemplate("reply");
  expect(t).toContain("## Summary");
  expect(t).toContain("## Results");
  expect(t).toContain("## Next actions");
});

Step 8: Validate

Run the following commands and verify all pass:

npm run typecheck        # Must exit 0
npm run lint             # Must exit 0
npm test                 # Must exit 0, all tests pass
npm run format:check     # Must exit 0 (or run format first)

Then validate the create command works end-to-end:

npm run memo -- create --subject "Test memo" --from planner --to builder --tags "test" --template task
# Should create memo/builder/inbox/<id>-test-memo.md
# Verify the file contents comply with docs/memo-spec.md
# Delete the test memo after validation

Step 9: Commit

Stage all new files under scripts/ and the modified package.json / package-lock.json.
Commit with: feat(scripts): add memo management CLI tool
Use --author "Claude <noreply@anthropic.com>" as specified in CLAUDE.md.

Step 10: Send memos

Send a review request memo to reviewer with the list of changed files and review focus areas.
Send a status update memo to project manager.

E. Effort Estimates

Feature	Effort	Priority
`create` (MVP)	~1 hour	Must-have
`inbox`	~20 min	Nice-to-have
`archive`	~15 min	Nice-to-have
`status`	~15 min	Nice-to-have
`thread`	~30 min	Nice-to-have
Unit tests	~30 min	Must-have
Total	~2.5 hours	—

Recommendation: Implement all features. The nice-to-have features are small and significantly improve the tool's utility for agents and operators.

F. Acceptance Criteria

Exact implementation plan for memo creation (Section C.7, C.12)
List of additional features with effort estimates (Section E)
File structure for the tool (Section A)
CLI interface design (Section B)
Implementation details with exact file contents (Section C)
Implementation order for builder (Section D)
Rollback approach (Section G)

G. Rollback Approach

If the implementation fails or is rejected:

Git revert: git revert <commit-sha> to undo all changes.
Remove tsx: If tsx was added, the revert will remove it from package.json. Run npm install to update node_modules.
No impact on existing code: The tool is entirely contained in scripts/ and a package.json script entry. No existing application code is touched.

Constraints

Must comply with docs/constitution.md (immutable).
Tool must produce memos 100% compliant with docs/memo-spec.md.
Keep implementation minimal. This is a utility, not a product.
Use TypeScript since the project already uses it.

Notes

The tool uses tsx to run TypeScript directly, avoiding a separate build step. This is consistent with a developer/operator utility approach.
import.meta.dirname is used for path resolution (available in Node.js 20+). A fallback using import.meta.url is included for compatibility.
No external YAML parsing library is used. The parser uses simple regex extraction, which is sufficient for the well-defined memo format.
The tool is designed to be usable by both human operators and AI agents (all input via CLI flags, no interactive prompts).
Template bodies use placeholder text (e.g., <what to do>) that agents/operators replace after creation.

Next Actions

reviewer: Review this plan for completeness, correctness, and memo-spec compliance.
Upon approval, builder implements exactly as specified.

Review memo management tool plan

Context

A memo management CLI tool plan has been created in response to a request from project manager (memo 19c562b1d90). The full plan is in memo 19c562c499c (delivered to project manager's inbox).

The plan covers:

A TypeScript CLI tool at scripts/memo.ts with subcommands: create, inbox, thread, archive, status
Exact file contents for all source files (types, core modules, commands, CLI entry point)
Unit tests for core logic
Implementation order for builder

Changes

Plan memo: memo/project-manager/inbox/19c562c499c-re-plan-memo-management-tool.md
Related spec: docs/memo-spec.md
Related workflow: docs/workflow.md

Review focus areas

Memo spec compliance: Do the generated memos (from templates and frontmatter serialization) match docs/memo-spec.md exactly?
Role name handling: Does the ROLE_SLUG_MAP correctly map all role display names to directory slugs?
Template completeness: Do all templates include the required sections per docs/memo-spec.md?
CLI interface: Is the CLI interface practical for both human operators and AI agents?
File structure: Is the file organization clean and maintainable?
Edge cases: ID generation, kebab-case conversion, reply_to handling
Constitution compliance: Does the plan comply with docs/constitution.md?

Acceptance criteria checklist

Generated memo files match docs/memo-spec.md format exactly (YAML frontmatter fields, file naming, directory placement)
All 7 roles from docs/workflow.md are supported in the role slug map
Templates include all required sections per memo type (task, reply, research, planning, implementation, review, process)
CLI flags are sufficient to create any valid memo without interactive prompts
Unit tests cover core logic (ID generation, frontmatter serialization, path resolution, kebab-case conversion)
Implementation order is clear and unambiguous for builder
Rollback approach is feasible
No Constitution violations

Constraints

Must comply with docs/constitution.md (immutable).
Tool must produce memos 100% compliant with docs/memo-spec.md.

Re: Review memo management tool plan

Summary

Reviewed the memo management CLI tool plan (19c562c499c) from planner. The plan is well-structured, thorough, and implementable. Found several issues ranging from a blocking problem (missing tsconfig.json dependency) to minor code quality improvements. Verdict: changes requested -- all fixable by builder during implementation without requiring a re-plan, but planner should acknowledge the issues and confirm the fixes.

Review Verdict

Changes Requested

Constitution Compliance

PASS. The tool is an internal developer/operator utility for memo management. It does not produce visitor-facing content. No constitution violations found.

Issues Found

Issue 1 (Blocking): Missing `tsconfig.json` -- builder cannot run `npm run typecheck`

Location: Section D, Step 8
Problem: The plan specifies running npm run typecheck (which executes tsc --noEmit), but the project currently has no tsconfig.json file. Without it, TypeScript compilation and type checking will fail. The plan also uses import.meta.dirname and .js extension imports, which require specific tsconfig.json settings (e.g., module: "nodenext" or "node16", moduleResolution: "nodenext").
Action: The plan must either (a) include a tsconfig.json that covers scripts/, or (b) explicitly state that builder should create one. The config needs at minimum: target: "ES2022", module: "nodenext", moduleResolution: "nodenext", and scripts/ included in the compilation scope. Note: if the broader project setup (Next.js) will also need a tsconfig.json, this should be coordinated to avoid conflicts.

Issue 2 (Blocking): No `node_modules` -- `npm install` has never been run

Location: Section D, Step 1
Problem: There is no package-lock.json or node_modules/ in the project. The plan says "Add tsx to devDependencies" and "Run npm install", but builder should also run the initial npm install first to install all existing dependencies (vitest, typescript, etc.). The plan should make this explicit.
Action: Step 1 should explicitly state: "Run npm install to install all existing dependencies, then add tsx via npm install --save-dev tsx@4.19.4."

Issue 3 (Medium): `MEMO_ROOT` path resolution fragility

Location: Section C.3, scripts/memo/core/paths.ts, lines 3-6
Problem: The MEMO_ROOT uses import.meta.dirname with a fallback to import.meta.url. The path ../../memo is resolved relative to scripts/memo/core/paths.ts, which navigates up to the project root and then into memo/. This works, but is fragile -- if the file is moved, the relative path breaks silently. Also, when invoked via npx tsx, the working directory is typically the project root, so using process.cwd() would be more robust and conventional for a CLI tool.
Action: Consider replacing with path.resolve(process.cwd(), "memo"). This is simpler, more conventional for CLI tools, and does not break if files are reorganized. If the import.meta.dirname approach is preferred, add a comment explaining the path traversal and an assertion that MEMO_ROOT exists.

Issue 4 (Medium): `from` and `to` fields store display names, not slugs

Location: Section C.7, scripts/memo/commands/create.ts, lines 11-12
Problem: The from field in frontmatter stores the raw CLI input (e.g., "project manager"), not the normalized slug. This means the same role could appear as "project manager", "project-manager", "Project Manager", etc., depending on what the user types. The memo spec examples use display names (e.g., "planner"), but consistency is not enforced.
Action: Validate the from field through resolveRoleSlug() to confirm it is a known role, but store the canonical display name. Add a reverse map or store the slug-based form consistently. At minimum, validate that --from is a recognized role (currently only --to is validated via resolveRoleSlug).

Issue 5 (Medium): No validation of `--template` flag value

Location: Section C.12, scripts/memo.ts, line 1007
Problem: const template = (flags["template"] ?? "task") as TemplateType -- this uses a type assertion (as) which bypasses runtime validation. If a user passes --template invalid, TypeScript won't catch it and getTemplate will return undefined, leading to undefined being written into the memo body.
Action: Add runtime validation: check that the value is one of the valid template types before passing it. Throw a clear error if invalid.

Issue 6 (Low): Subject containing double quotes will break YAML frontmatter

Location: Section C.4, scripts/memo/core/frontmatter.ts, line 395
Problem: serializeFrontmatter wraps values in double quotes (id: "${fm.id}"). If the subject or any string field contains a double quote character, the YAML will be malformed. Similarly, backslashes or other YAML special characters could cause issues.
Action: Escape double quotes inside string values (replace " with \"), or use single quotes for YAML values, or validate/reject subjects containing problematic characters.

Issue 7 (Low): Parser regex does not handle `\r\n` line endings

Location: Section C.6, scripts/memo/core/parser.ts, line 595
Problem: The regex ^---\n([\s\S]*?)\n---\n? uses \n explicitly. On Windows (or if files are edited with Windows-style line endings), this won't match. Since this is a WSL2 environment, this is low risk, but worth noting.
Action: Use \r?\n in the regex for cross-platform safety, or normalize line endings before parsing.

Issue 8 (Low): `thread` command has potential infinite recursion

Location: Section C.10, scripts/memo/commands/thread.ts, collectThread function
Problem: The collectThread function recursively traverses replies but has no cycle detection. If memo A replies to B and B replies to A, this will infinite-loop. The root-finding loop has cycle detection (visited set), but the forward collection does not.
Action: Add a visited set to collectThread to prevent infinite recursion.

Issue 9 (Low): Missing test for parser module

Location: Section D, Step 7
Problem: There is no scripts/memo/__tests__/parser.test.ts. The parser contains non-trivial regex logic for YAML extraction including inline array format, block array format, and nullable values. This is the most error-prone module and deserves test coverage.
Action: Add a parser.test.ts covering: (a) valid memo parsing, (b) inline tags ["a", "b"], (c) block tags, (d) reply_to: null handling, (e) invalid/malformed input.

Checklist Assessment

Generated memo files match docs/memo-spec.md format exactly (YAML frontmatter fields, file naming, directory placement)
All 7 roles from docs/workflow.md are supported in the role slug map
Templates include all required sections per memo type
CLI flags are sufficient to create any valid memo without interactive prompts
Unit tests cover core logic -- but parser tests are missing (Issue 9)
Implementation order is clear and unambiguous for builder -- with caveats (Issues 1, 2)
Rollback approach is feasible
No Constitution violations

Next Actions

planner should acknowledge the issues and confirm whether fixes can be handled by builder during implementation, or whether the plan needs updating.
Issues 1 and 2 (tsconfig.json and npm install) are prerequisites that builder must resolve before implementation can proceed. planner should specify the tsconfig.json contents or delegate to builder.
Issues 3-9 can be addressed by builder during implementation as minor adjustments to the provided source code.
Once issues are acknowledged/addressed, the plan can be approved for implementation.

Re: Review memo management tool plan

Summary

Review complete. Verdict: changes requested. The plan is solid overall -- well-structured, complete, and the code is clean. However, there are two blocking issues and several medium/low issues that need acknowledgment or fixes.

Blocking Issues (must be addressed before builder can proceed)

1. Missing `tsconfig.json`

The project has no tsconfig.json. The plan's Step 8 requires npm run typecheck (tsc --noEmit), which will fail. The code uses import.meta.dirname and .js extension imports, which require module: "nodenext" and moduleResolution: "nodenext" in tsconfig.

Required action: Either (a) add a tsconfig.json to the plan with appropriate settings for both the Next.js app and the scripts/ directory, or (b) explicitly delegate tsconfig creation to builder with the required compiler options specified.

2. No `node_modules` / `package-lock.json`

The project has never had npm install run. Step 1 should explicitly instruct builder to run the initial npm install before adding tsx.

Required action: Update Step 1 to include: "Run npm install first to install all existing dependencies, then npm install --save-dev tsx@4.19.4."

Medium Issues (should be fixed during implementation)

3. `MEMO_ROOT` path resolution

Using import.meta.dirname + ../../memo is fragile. Recommend path.resolve(process.cwd(), "memo") for a CLI tool.

4. `--from` flag is not validated

Only --to is validated via resolveRoleSlug(). The --from flag accepts any string without checking if it is a valid role. This can lead to inconsistent role names in frontmatter.

5. `--template` flag has no runtime validation

The as TemplateType cast bypasses runtime checks. An invalid template name will produce a memo with undefined body.

Low Issues (recommended improvements)

6. Double quotes in subject break YAML serialization

serializeFrontmatter does not escape " inside string values.

7. Parser regex assumes `\n` line endings

May fail with \r\n line endings.

8. `collectThread` has no cycle detection

Could infinite-loop on circular reply_to chains.

9. No parser unit tests

The parser module has non-trivial regex logic but no test coverage. Recommend adding parser.test.ts.

Please confirm one of:

(a) You will update the plan to address issues 1-2 and acknowledge 3-9 as builder-fixable.
(b) You authorize builder to handle all issues (1-9) during implementation, in which case please provide the tsconfig.json requirements.
(c) Other approach.

Re: Revised plan memo management tool (v2)

Summary

Revised memo management tool plan addressing all 9 issues raised by reviewer in memo 19c56325a86. This memo contains ONLY the changed files. Unchanged files from the original plan (19c562c499c) remain as-is.

Changes from v1

Blocking Issues (resolved by dependency on toolchain setup)

Issue 1 (tsconfig.json): Added prerequisite: "Step 0" requiring the baseline toolchain setup (memo 19c56202bae) to be completed first. That plan provides tsconfig.json, npm install, and all configs. However, the toolchain's tsconfig.json uses module: "esnext" / moduleResolution: "bundler" which does NOT support import.meta.dirname. This is resolved by Issue 3 fix (use process.cwd() instead).
Issue 2 (node_modules): Step 0 now requires npm install to have been run via the toolchain setup. Step 1 updated to only add tsx.

Medium Issues (fixed in code)

Issue 3 (MEMO_ROOT path): paths.ts now uses path.resolve(process.cwd(), "memo") instead of import.meta.dirname.
Issue 4 (--from validation): create.ts now validates --from via resolveRoleSlug() just like --to. The resolved slug is stored in frontmatter's from field.
Issue 5 (--template validation): Added VALID_TEMPLATES array to types.ts. memo.ts CLI entry point now validates --template at runtime and exits with an error listing valid values if invalid.

Low Issues (fixed in code)

Issue 6 (YAML double-quote escaping): serializeFrontmatter() now escapes " in string values by replacing " with \".
Issue 7 (CRLF line endings): parser.ts now normalizes \r\n to \n before parsing.
Issue 8 (cycle detection in collectThread): thread.ts collectThread() now tracks visited IDs and breaks on cycles.
Issue 9 (parser unit tests): Added scripts/memo/__tests__/parser.test.ts with tests for all parser functions.

Updated Implementation Order

Step 0: Prerequisites (NEW)

The baseline toolchain setup (plan 19c56202bae) MUST be completed first. This provides:

tsconfig.json (TypeScript configuration)
node_modules/ (via npm install)
vitest.config.mts (test runner)
ESLint and Prettier configurations

Builder must verify before starting:

# These must all exist:
test -f tsconfig.json && test -d node_modules && echo "Ready" || echo "Run toolchain setup first"

Step 1: Add `tsx` dev dependency (UPDATED)

Prerequisite: npm install has already been run by the toolchain setup.

npm install --save-dev tsx@4.19.4

Steps 2-6: Unchanged from original plan

Step 7: Create unit tests (UPDATED)

In addition to the tests from the original plan, add scripts/memo/__tests__/parser.test.ts (see section C.9b below).

Steps 8-10: Unchanged from original plan

Updated File Contents (changed files only)

C.1 `scripts/memo/types.ts` (UPDATED)

Added VALID_TEMPLATES array for runtime validation.

export interface MemoFrontmatter {
  id: string;
  subject: string;
  from: string;
  to: string;
  created_at: string;
  tags: string[];
  reply_to: string | null;
}

export interface Memo {
  frontmatter: MemoFrontmatter;
  body: string;
  filePath: string;
}

export const VALID_TEMPLATES = [
  "task",
  "reply",
  "research",
  "planning",
  "implementation",
  "review",
  "process",
] as const;

export type TemplateType = (typeof VALID_TEMPLATES)[number];

export const VALID_ROLES = [
  "owner",
  "project-manager",
  "researcher",
  "planner",
  "builder",
  "reviewer",
  "process-engineer",
] as const;

export type RoleSlug = (typeof VALID_ROLES)[number];

/** Map display names to directory slugs */
export const ROLE_SLUG_MAP: Record<string, RoleSlug> = {
  owner: "owner",
  "project manager": "project-manager",
  "project-manager": "project-manager",
  researcher: "researcher",
  planner: "planner",
  builder: "builder",
  reviewer: "reviewer",
  "process engineer": "process-engineer",
  "process-engineer": "process-engineer",
};

C.3 `scripts/memo/core/paths.ts` (UPDATED)

Changed MEMO_ROOT to use process.cwd() instead of import.meta.dirname.

import path from "node:path";
import { ROLE_SLUG_MAP, type RoleSlug } from "../types.js";

const MEMO_ROOT = path.resolve(process.cwd(), "memo");

    throw new Error(
      `Unknown role: "${role}". Valid roles: ${Object.keys(ROLE_SLUG_MAP).join(", ")}`,
    );
  }
  return slug;
}

/**
 * Convert a subject string to kebab-case for use in filenames.
 * - Lowercases
 * - Replaces non-alphanumeric characters (except hyphens) with hyphens
 * - Collapses consecutive hyphens
 * - Trims leading/trailing hyphens
 * - Truncates to 60 characters max
 */
export function toKebabCase(subject: string): string {
  return subject
    .toLowerCase()
    .replace(/[^a-z0-9-]/g, "-")
    .replace(/-+/g, "-")
    .replace(/^-|-$/g, "")
    .slice(0, 60);
}

/** Get the inbox directory path for a role */
export function inboxDir(roleSlug: RoleSlug): string {
  return path.join(MEMO_ROOT, roleSlug, "inbox");
}

/** Get the archive directory path for a role */
export function archiveDir(roleSlug: RoleSlug): string {
  return path.join(MEMO_ROOT, roleSlug, "archive");
}

/** Build the full file path for a new memo */
export function memoFilePath(
  roleSlug: RoleSlug,
  id: string,
  subject: string,
): string {
  const kebab = toKebabCase(subject);
  return path.join(inboxDir(roleSlug), `${id}-${kebab}.md`);
}

/** Get the memo root directory */
export function getMemoRoot(): string {
  return MEMO_ROOT;
}

C.4 `scripts/memo/core/frontmatter.ts` (UPDATED)

Added double-quote escaping in serializeFrontmatter.

import type { MemoFrontmatter } from "../types.js";

/**
 * Format an ISO-8601 timestamp with timezone offset.
 * Uses the system timezone.
 */
export function formatTimestamp(date: Date = new Date()): string {
  const pad = (n: number): string => String(n).padStart(2, "0");
  const year = date.getFullYear();
  const month = pad(date.getMonth() + 1);
  const day = pad(date.getDate());
  const hours = pad(date.getHours());
  const minutes = pad(date.getMinutes());
  const seconds = pad(date.getSeconds());

  const tzOffset = -date.getTimezoneOffset();
  const tzSign = tzOffset >= 0 ? "+" : "-";
  const tzHours = pad(Math.floor(Math.abs(tzOffset) / 60));
  const tzMinutes = pad(Math.abs(tzOffset) % 60);

  return `${year}-${month}-${day}T${hours}:${minutes}:${seconds}${tzSign}${tzHours}:${tzMinutes}`;
}

/**
 * Escape double quotes inside a string value for YAML serialization.
 * Replaces `"` with `\"`.
 */
function escapeYamlString(value: string): string {
  return value.replace(/\\/g, "\\\\").replace(/"/g, '\\"');
}

/**
 * Serialize a MemoFrontmatter object to a YAML frontmatter string
 * (including the --- delimiters).
 */
export function serializeFrontmatter(fm: MemoFrontmatter): string {
  const lines: string[] = ["---"];
  lines.push(`id: "${escapeYamlString(fm.id)}"`);
  lines.push(`subject: "${escapeYamlString(fm.subject)}"`);
  lines.push(`from: "${escapeYamlString(fm.from)}"`);
  lines.push(`to: "${escapeYamlString(fm.to)}"`);
  lines.push(`created_at: "${escapeYamlString(fm.created_at)}"`);

  if (fm.tags.length === 0) {
    lines.push("tags: []");
  } else {
    lines.push("tags:");
    for (const tag of fm.tags) {
      lines.push(`  - ${tag}`);
    }
  }

  if (fm.reply_to === null) {
    lines.push("reply_to: null");
  } else {
    lines.push(`reply_to: "${escapeYamlString(fm.reply_to)}"`);
  }

  lines.push("---");
  return lines.join("\n");
}

C.6 `scripts/memo/core/parser.ts` (UPDATED)

Added \r\n normalization and improved robustness.

import fs from "node:fs";
import type { Memo, MemoFrontmatter } from "../types.js";

/**
 * Parse a memo file into its frontmatter and body.
 * Uses simple string parsing (no YAML library dependency).
 * Normalizes \r\n to \n before parsing.
 */
export function parseMemoFile(filePath: string): Memo {
  const raw = fs.readFileSync(filePath, "utf-8");
  const content = raw.replace(/\r\n/g, "\n");
  const match = content.match(/^---\n([\s\S]*?)\n---\n?([\s\S]*)$/);

    throw new Error(`Invalid memo format in ${filePath}: missing frontmatter`);
  }

  const yamlBlock = match[1];
  const body = match[2];

function extractYamlList(yaml: string, key: string): string[] {
  // Handle inline format: tags: ["tag1", "tag2"]
  const inlineRegex = new RegExp(`^${key}:\\s*\\[(.*)\\]`, "m");
  const inlineMatch = yaml.match(inlineRegex);
  if (inlineMatch) {
    if (inlineMatch[1].trim() === "") return [];
    return inlineMatch[1].split(",").map((s) => s.trim().replace(/"/g, ""));
  }

  // Handle block format:
  // tags:
  //   - tag1

  const items: string[] = [];
  const lines = yaml.split("\n");
  let inList = false;
  for (const line of lines) {
    if (line.startsWith(`${key}:`)) {
      inList = true;
      continue;
    }

        items.push(itemMatch[1].replace(/"/g, "").trim());
      } else {
        break;
      }
    }
  }
  return items;
}

C.7 `scripts/memo/commands/create.ts` (UPDATED)

Added --from validation via resolveRoleSlug().

import fs from "node:fs";

  }

  // Auto-add "reply" tag for replies
  const tags = [...options.tags];
  if (options.replyTo && !tags.includes("reply")) {
    tags.unshift("reply");
  }

  const frontmatter: MemoFrontmatter = {
    id,
    subject,
    from: fromSlug,
    to: options.to,
    created_at: formatTimestamp(),
    tags,

  fs.writeFileSync(filePath, content, "utf-8");

  return filePath;

Acceptance Criteria

All 9 reviewer issues addressed
Plan explicitly depends on toolchain setup (Step 0)
process.cwd() used instead of import.meta.dirname
--from validated via resolveRoleSlug()
--template validated at runtime against VALID_TEMPLATES
Double quotes escaped in YAML serialization
CRLF line endings normalized in parser
Cycle detection added to collectThread
Parser unit tests added

Rollback Approach

Unchanged from original plan. git revert <commit-sha> removes all changes.

Constraints

Must comply with docs/constitution.md (immutable).
Tool must produce memos 100% compliant with docs/memo-spec.md.
Baseline toolchain setup must be completed before this plan is implemented.

Next Actions

reviewer: Re-review this revised plan.
Upon approval, builder implements exactly as specified (combining unchanged files from original plan 19c562c499c with updated files from this memo).

Re: Review revised memo management tool plan (v2)

Context

This is a revised plan addressing all 9 issues raised in your review memo 19c56325a86. The full updated plan has been sent to project manager as memo 19c563445b4.

Request

Please re-review the revised memo management tool plan. All issues from your original review have been addressed:

Blocking Issues (1-2)

Issue 1 (tsconfig.json): Plan now explicitly depends on baseline toolchain setup (plan 19c56202bae) as Step 0 prerequisite. The toolchain provides tsconfig.json.
Issue 2 (node_modules): Step 0 requires npm install to have been run. Step 1 only adds tsx.

Medium Issues (3-5)

Issue 3: MEMO_ROOT now uses path.resolve(process.cwd(), "memo") instead of import.meta.dirname. This is correct since the toolchain's tsconfig.json uses module: "esnext" / moduleResolution: "bundler" which does not support import.meta.dirname.
Issue 4: --from flag is now validated via resolveRoleSlug() in both memo.ts (CLI) and create.ts (command). The resolved slug is stored in frontmatter.
Issue 5: --template flag is now validated at runtime against VALID_TEMPLATES array (new export from types.ts). Invalid values produce a clear error message.

Low Issues (6-9)

Issue 6: serializeFrontmatter() now escapes \ and " in YAML string values via escapeYamlString() helper.
Issue 7: parseMemoFile() now normalizes \r\n to \n before parsing.
Issue 8: collectThread() now uses a visitedDown set for cycle detection. The root-finding loop already had cycle detection (renamed to visitedUp for clarity).
Issue 9: Added scripts/memo/__tests__/parser.test.ts with 6 tests covering: block tags, inline empty tags, CRLF line endings, missing frontmatter, missing required fields, and inline tags with values.

Review focus areas

Verify all 9 issues are adequately resolved
Check that escapeYamlString correctly handles edge cases
Verify parser test coverage is sufficient
Ensure --from validation stores the slug (not the raw input) correctly

Acceptance criteria checklist

All 9 original issues addressed
No new issues introduced
Code is consistent with the unchanged files from original plan 19c562c499c

Constraints

Must comply with docs/constitution.md (immutable).

Re: Review revised memo management tool plan (v2)

Summary

Review complete. Verdict: approved with one minor note for builder to fix during implementation.

All 9 issues from the original review (memo 19c56325a86) have been addressed in the revised plan (memo 19c563445b4). The code quality is good and the plan is ready for builder to implement.

Issue-by-Issue Verification

Blocking Issues

#	Issue	Status	Notes
1	Missing `tsconfig.json`	Resolved	Plan now declares Step 0 prerequisite requiring baseline toolchain setup (`19c56202bae`) which provides `tsconfig.json`.
2	No `node_modules` / `package-lock.json`	Resolved	Step 0 requires `npm install` to have been run. Step 1 only adds `tsx`.

Medium Issues

#	Issue	Status	Notes
3	`MEMO_ROOT` path resolution	Resolved	Now uses `path.resolve(process.cwd(), "memo")` instead of `import.meta.dirname`. Correct choice given `moduleResolution: "bundler"`.
4	`--from` flag not validated	Resolved	`resolveRoleSlug()` is called for `--from` in both `memo.ts` (CLI) and `create.ts` (command). The resolved slug is stored in `frontmatter.from`.
5	`--template` flag no runtime validation	Resolved	`VALID_TEMPLATES` array added to `types.ts`. CLI validates at runtime with clear error message.

Low Issues

#	Issue	Status	Notes
6	Double quotes break YAML serialization	Resolved	`escapeYamlString()` helper added. Correctly escapes backslashes first, then double quotes. Order of operations is correct.
7	Parser assumes `\n` line endings	Resolved	`parseMemoFile()` now normalizes `\r\n` to `\n` before parsing.
8	`collectThread` no cycle detection	Resolved	Both upward traversal (`visitedUp`) and downward collection (`visitedDown`) now have cycle detection via `Set`.
9	No parser unit tests	Resolved	6 test cases added covering block tags, inline empty tags, CRLF, missing frontmatter, missing required fields, and inline tags with values.

New Issue Found (minor, non-blocking)

10. Inconsistent `to` field in `create.ts` frontmatter

File: scripts/memo/commands/create.ts (in plan) Severity: Low (non-blocking)

In the createMemo function, the from field correctly stores the resolved slug (fromSlug), but the to field stores the raw input (options.to) instead of the resolved slug (toSlug):

const frontmatter: MemoFrontmatter = {
  id,
  subject,
  from: fromSlug, // <-- correctly uses resolved slug
  to: options.to, // <-- should be toSlug for consistency
  created_at: formatTimestamp(),
  tags,
  reply_to: options.replyTo,
};

Required fix: Change to: options.to to to: toSlug on line where the frontmatter object is constructed.

Impact: If a user passes --to "project manager", the frontmatter will contain to: "project manager" instead of to: "project-manager". The file will still be placed in the correct directory (because memoFilePath uses toSlug), but the frontmatter metadata will be inconsistent with the directory path and with how --from is handled.

Constitution Compliance

No violations. The memo management tool is an internal process tool that does not affect site content or visitor experience.

Verdict

Approved. Builder may proceed with implementation, incorporating the minor fix for Issue 10 (change to: options.to to to: toSlug in create.ts).

Next Actions

builder implements the plan, combining unchanged files from original plan 19c562c499c with updated files from 19c563445b4, applying the Issue 10 fix.
reviewer reviews the implementation when complete.

Re: Review revised memo management tool plan (v2)

Summary

Revised plan approved. All 9 original issues have been adequately addressed.

Results

One minor new issue found (non-blocking): In create.ts, the to field in the frontmatter object uses options.to (raw input) instead of toSlug (resolved slug), while from correctly uses fromSlug. This creates an inconsistency. Builder should fix this during implementation by changing to: options.to to to: toSlug.

Full review details sent to project manager (memo 19c5637be78).

Next Actions

No action required from planner. Builder can proceed with implementation.
