/docs-reflect — Session knowledge → repo documentation

Collect DOC: notes accumulated during the session, generalize them into rules, and propose documentation for the repository.

Step 1: Collect findings

Two sources: DOC: notes from the current session, and recurring feedback from memory.

1a: DOC: notes

node "$MEM" --dir="$MEM_DIR" docs

1b: Recurring feedback patterns

node "$MEM" --dir="$MEM_DIR" recurring

This scans feedback/ files for clusters — similar corrections that appeared 2+ times across sessions. Recurring patterns are strong candidates for promotion to .claude/rules/.

Combine

If both sources are empty — tell user "No documentation findings." and stop.

If recurring patterns found (3+ occurrences) — these are project conventions, not personal preferences. Treat them as DOC automatically:

• Save as DOC note: node "$MEM" --dir="$MEM_DIR" note "DOC: <domain> — <generalized rule from recurring feedback>"
• Highlight to user: "This feedback appeared N times — promoting to project rule."

Patterns with 2 occurrences — mention as candidates but don't auto-promote.

Step 2: Generalize

For each DOC: note, extract a generalized rule.

Bad (too specific):

"The PaymentService bug was on line 42 in processRefund()"

Good (pattern):

"Refund operations must check transaction state before mutating — stale state causes double-refunds"

Bad (class-level):

"UserService.getProfile() returns null when user is not found"

Good (convention):

"Services return null for missing entities instead of throwing — callers must handle null"

If a note can't be generalized — skip it.

Step 3: Detect documentation structure and route

3a: Detect existing structure

ls .claude/rules/ 2>/dev/null
cat CLAUDE.md 2>/dev/null | head -50
ls docs/ 2>/dev/null

Check memory for saved preference:

node "$MEM" --dir="$MEM_DIR" search "docs_target"

3b: Choose target

If no saved preference and no .claude/rules/ directory — ask:

Where should project rules go?
  1. .claude/rules/ (Claude Code loads these per-directory)
  2. docs/
  3. CLAUDE.md (single file, always loaded — use sparingly)
  4. Other — specify path

Choice? (default: 1)

Save preference:

node "$MEM" --dir="$MEM_DIR" note "CONFIG: docs_target=<chosen path>"

3c: Route by domain

Route using the chosen target directory (default: .claude/rules/):

If a matching file exists — add to it. If not — create one.

Step 4: Propose changes

## Docs-reflect: <date>

Found N DOC: notes, grouped into M domains:

### <target>/testing.md
- <rule 1>
- <rule 2>

### <target>/api.md
- <rule 3>

### Skipped
- <notes too specific to generalize>

Apply? (all / pick numbers / skip)

Wait for user confirmation.

Step 5: Apply

For each approved rule:

1. Read target file (or create with header)
2. Add rule to appropriate section
3. Format:

For rule files (.claude/rules/, docs/, or custom target):

## <Section>

- <Rule>

Rules

• Generalize or skip. Can't state it as a reusable rule → don't add it.
• No class/method API docs. Those belong in code comments.
• No ticket/branch references. Docs should not mention specific tasks.
• Right file matters. The main value is routing to the correct .claude/rules/ file.
• Deduplicate. Read existing docs before adding.
• User confirms first. Never write without showing what will be added.
• Respect existing structure. Add to existing files/sections. Don't reorganize.
• Less is more. 2 good rules is a great outcome. 0 is fine too.
