CLAUDE.md Maintainer

CLAUDE.md Maintainer

Audit and maintain CLAUDE.md files across any repository. Ensures they function as Claude Code memory (not user documentation).

Core Principle

CLAUDE.md is Claude's memory, not a README. Every line loads into context, so keep it lean and actionable.

Algorithm

Phase 1: Plan (read-only)

1. Discover existing memory files:

   • ./​CLAUDE.md or ./​.claude/​CLAUDE.md
   • ./​CLAUDE.local.md
   • Nested **/​CLAUDE.md
   • .claude/​rules/​**/​*.md

2. Validate each against invariants (see docs/​invariants.md)

3. Audit verbosity:

   • Count total lines (warn if > 300, suggest if > 60)
   • Detect verbose patterns (see docs/​verbose-patterns.md)
   • Flag linter-duplicating instructions
   • Identify content that should move to agent_docs/
   • Report actionable findings with line numbers

4. Identify module roots (see docs/​directory-heuristics.md)

5. Output proposed changes:

   • Files to update (with change summary)
   • Files to create
   • Ambiguous cases requiring human decision

Phase 2: Apply (with confirmation)

Only after user confirms:

1. Update existing files
2. Create missing files from templates
3. Report final state

Init Algorithm

For /​bluera-base:claude-code-md init - creates new CLAUDE.md from scratch.

Detection Priority

Check files in order (stop at first match):

package.json → JavaScript/​TypeScript
Cargo.toml   → Rust
pyproject.toml → Python
go.mod       → Go

Lockfile → Package Manager

Script Extraction

JavaScript/​TypeScript:

jq -r '.scripts | keys[]' package.json 2>/​dev/​null | head -10

Python (pyproject.toml):

grep -A 20 '^\[project.scripts\]' pyproject.toml | grep '=' | cut -d'=' -f1 | tr -d ' "'

Rust/​Go: Use standard commands (cargo build/​test, go build/​test).

Generated Structure

includes/​CLAUDE-BASE.md

---

## Package Manager

**Use `{PM}`** - All scripts: `{PM} run <script>`

---

## Scripts

{SCRIPTS - grouped by category if many}

---

## CI/​CD

{Only if .github/​workflows/ or .gitlab-ci.yml exists}

---

Design Principles

1. Auto-detect over ask - Only interview when ambiguous
2. < 60 lines target - Start lean, user expands later
3. Never overwrite - Check for existing CLAUDE.md first
4. @include always - Start with CLAUDE-BASE.md reference

---

Learn Algorithm

For /​bluera-base:claude-code-md learn - adds learnings to marker-delimited regions.

Marker Format

## Auto-Learned (bluera-base)
<!-- AUTO:bluera-base:learned -->
- Learning 1
- Learning 2
<!-- END:bluera-base:learned -->

Algorithm Steps

1. Determine target file:

   • Default: CLAUDE.local.md (personal, gitignored)
   • With --shared: CLAUDE.md (team-shared)

2. Read target file (or create if missing)

3. Find markers:

   • Start: <!-- AUTO:bluera-base:learned -->
   • End: <!-- END:bluera-base:learned -->

4. If markers missing: Insert at end of file:

   
   ---
   
   ## Auto-Learned (bluera-base)
   <!-- AUTO:bluera-base:learned -->
   <!-- END:bluera-base:learned -->
   

5. Parse existing learnings between markers into list

6. Dedupe check:

   • Normalize: trim whitespace, lowercase
   • If learning already exists (fuzzy match), skip with message

7. Secrets check (CRITICAL):

   • Regex: api[_-]?key|token|password|secret|-----BEGIN|AWS_|GITHUB_TOKEN|ANTHROPIC_API
   • If match: REJECT with warning, do NOT write

8. Hard cap check:

   • Max 50 lines in auto-managed section
   • If exceeded: warn user, suggest pruning old learnings

9. Insert learning as new bullet point

10. Write file using Edit tool (replace marker region only)

Secrets Denylist

api[_-]?key
token
password
secret
-----BEGIN
AWS_
GITHUB_TOKEN
ANTHROPIC_API_KEY
OPENAI_API_KEY
private[_-]?key
credential

Example Implementation

# Pseudo-code for the Edit operation
OLD_CONTENT="<!-- AUTO:bluera-base:learned -->
- Old learning 1
<!-- END:bluera-base:learned -->"

NEW_CONTENT="<!-- AUTO:bluera-base:learned -->
- Old learning 1
- New learning here
<!-- END:bluera-base:learned -->"

---

User Control Modes

Control auto-learning behavior via /​bluera-base:config command:

/​bluera-base:config enable auto-learn    # Opt-in to learning observation
/​bluera-base:config set .autoLearn.mode auto  # Change mode

Configuration stored in .bluera/​bluera-base/​config.json:

{
  "autoLearn": {
    "enabled": false,    // opt-in by default
    "mode": "suggest",   // suggest | auto
    "threshold": 3,      // occurrences before suggesting
    "target": "local"    // local | shared
  }
}

Session signals are tracked in .bluera/​bluera-base/​state/​session-signals.json (ephemeral, gitignored). Commands with ≥threshold occurrences trigger learning suggestions.

Key Rules

1. Never duplicate - Module CLAUDE.md should not repeat root rules
2. Prefer rules files - Move topic-specific rules to .claude/​rules/<topic>.md
3. Use paths: scoping - Rules files can use paths: frontmatter
4. Hard cap - If > 25 modules, summarize at bucket level, defer individuals

Output Format

Report these sections:

• Memory files found
• Files to create
• Files to update (with diff summary)
• Rules files to create/​update
• Verbosity report (if issues detected)
• Follow-ups (ambiguous items)

Verbosity Report

When line count exceeds targets or verbose patterns detected, include:

Line Count:

• CLAUDE.md: 142 lines (target: < 60, hard limit: < 300)

Verbose Patterns Detected:
