audit-discovery-symlinks

# audit-discovery-symlinks

## When to Use

- After adding new skills, agents, or teams to the almanac
- After a repository rename or move that may have broken absolute symlinks
- When slash commands or agents are not found in Claude Code
- As a periodic health check to catch drift between registries and discovery paths
- When onboarding a new project that should discover shared almanac content

**Do NOT use** for creating the initial symlink hub from scratch. See the [symlink-architecture guide](../../guides/symlink-architecture.md) for first-time setup.

## Inputs

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `almanac_path` | string | No | Absolute path to agent-almanac root. Auto-detected from `.claude/` symlink targets or cwd if omitted |
| `scope` | enum | No | `project`, `global`, or `both` (default: `both`) |
| `fix_mode` | enum | No | `report` (default: audit only), `auto` (fix all safe issues), `interactive` (prompt before each fix) |

## Procedure

### Step 1: Identify Almanac Path

Locate the agent-almanac root directory.

```bash
# Auto-detect from current project's .claude/agents symlink
ALMANAC_PATH=$(readlink -f .claude/agents 2>/dev/null | sed 's|/agents$||')

# Fallback: check if cwd is the almanac
if [ -z "$ALMANAC_PATH" ] || [ ! -f "$ALMANAC_PATH/skills/_registry.yml" ]; then
  if [ -f "skills/_registry.yml" ]; then
    ALMANAC_PATH=$(pwd)
  fi
fi

# Fallback: check global agents symlink
if [ -z "$ALMANAC_PATH" ] || [ ! -f "$ALMANAC_PATH/skills/_registry.yml" ]; then
  ALMANAC_PATH=$(readlink -f ~/.claude/agents 2>/dev/null | sed 's|/agents$||')
fi

echo "Almanac path: $ALMANAC_PATH"
```

**Got:** `ALMANAC_PATH` points to a directory containing `skills/_registry.yml`, `agents/_registry.yml`, and `teams/_registry.yml`.

**If fail:** If auto-detection fails, ask the user for the `almanac_path` input. The almanac root is the directory containing `skills/`, `agents/`, `teams/`, and their registries.

### Step 2: Inventory Registries

Extract the canonical lists of skills, agents, and teams from their registries.

```bash
# Count registered skills (entries with "- id:" under domain sections)
REGISTERED_SKILLS=$(grep '^ \{6\}- id:' "$ALMANAC_PATH/skills/_registry.yml" | awk '{print $3}' | sort)
REGISTERED_SKILL_COUNT=$(echo "$REGISTERED_SKILLS" | wc -l)

# Count registered agents
REGISTERED_AGENTS=$(grep '^ \{2\}- id:' "$ALMANAC_PATH/agents/_registry.yml" | awk '{print $3}' | sort)
REGISTERED_AGENT_COUNT=$(echo "$REGISTERED_AGENTS" | wc -l)

# Count registered teams
REGISTERED_TEAMS=$(grep '^ \{2\}- id:' "$ALMANAC_PATH/teams/_registry.yml" | awk '{print $3}' | sort)
REGISTERED_TEAM_COUNT=$(echo "$REGISTERED_TEAMS" | wc -l)

echo "Registered: $REGISTERED_SKILL_COUNT skills, $REGISTERED_AGENT_COUNT agents, $REGISTERED_TEAM_COUNT teams"
```

**Got:** Counts match the `total_skills`, `total_agents`, `total_teams` values in each registry header.

**If fail:** If counts diverge from the header totals, the registry itself is out of sync. Note the discrepancy in the report but continue with the actual `- id:` entries as the source of truth.

### Step 3: Audit Project-Level Symlinks

Check `.claude/skills/*`, `.claude/agents`, `.claude/teams` in the current project directory.

```bash
PROJECT_CLAUDE=".claude"

# --- Skills ---
# Items on disk (excluding _template)
PROJECT_SKILLS=$(ls "$PROJECT_CLAUDE/skills/" 2>/dev/null | grep -v '^_template$' | sort)
PROJECT_SKILL_COUNT=$(echo "$PROJECT_SKILLS" | grep -c .)

# Missing: in registry but not in project .claude/skills/
MISSING_PROJECT_SKILLS=$(comm -23 <(echo "$REGISTERED_SKILLS") <(echo "$PROJECT_SKILLS"))

# Broken: symlink exists but target doesn't resolve
BROKEN_PROJECT_SKILLS=$(find "$PROJECT_CLAUDE/skills/" -maxdepth 1 -type l ! -exec test -e {} \; -printf '%f\n' 2>/dev/null | sort)

# Extraneous: in project but not in registry (and not external)
EXTRA_PROJECT_SKILLS=$(comm -13 <(echo "$REGISTERED_SKILLS") <(echo "$PROJECT_SKILLS"))

# --- Agents ---
if [ -L "$PROJECT_CLAUDE/agents" ] || [ -d "$PROJECT_CLAUDE/agents" ]; then
  PROJECT_AGENT_STATUS="OK"
  test -d "$PROJECT_CLAUDE/agents" || PROJECT_AGENT_STATUS="BROKEN"
  PROJECT_AGENT_COUNT=$(ls "$PROJECT_CLAUDE/agents/"*.md 2>/dev/null | wc -l)
else
  PROJECT_AGENT_STATUS="MISSING"
  PROJECT_AGENT_COUNT=0
fi

# --- Teams ---
# Teams are NOT symlinked. TeamCreate uses ~/.claude/teams/ for runtime state.
# A .claude/teams symlink is a misconfiguration — warn if found.
if [ -L "$PROJECT_CLAUDE/teams" ]; then
  PROJECT_TEAM_STATUS="MISCONFIGURED"
  PROJECT_TEAM_COUNT=0
  # Stale symlink — should be removed to avoid collision with TeamCreate
else
  PROJECT_TEAM_STATUS="OK"
  PROJECT_TEAM_COUNT=0
fi
```

**Got:** Zero missing, zero broken. Extraneous items are classified and explained.

**If fail:** If `.claude/` does not exist at all, the project has no discovery setup. Note this and skip to global audit.

### Step 4: Audit Global Symlinks

Check `~/.claude/skills/*` and `~/.claude/agents`. Also check that `~/.claude/teams` is NOT a symlink (it should be absent or a directory for TeamCreate runtime state).

```bash
GLOBAL_CLAUDE="$HOME/.claude"

# --- Skills ---
GLOBAL_SKILLS_ALL=$(ls "$GLOBAL_CLAUDE/skills/" 2>/dev/null | sort)

# Classify each entry: almanac vs external
ALMANAC_GLOBAL_SKILLS=""
EXTERNAL_GLOBAL_SKILLS=""
for item in $GLOBAL_SKILLS_ALL; do
  target=$(readlink -f "$GLOBAL_CLAUDE/skills/$item" 2>/dev/null)
  if [ -z "$target" ]; then
    # Real directory (not a symlink) — external
    EXTERNAL_GLOBAL_SKILLS="$EXTERNAL_GLOBAL_SKILLS $item"
  elif echo "$target" | grep -q "^$ALMANAC_PATH"; then
    ALMANAC_GLOBAL_SKILLS="$ALMANAC_GLOBAL_SKILLS $item"
  else
    EXTERNAL_GLOBAL_SKILLS="$EXTERNAL_GLOBAL_SKILLS $item"
  fi
done

# Filter: _template is always extraneous for almanac content
ALMANAC_GLOBAL_SKILLS=$(echo "$ALMANAC_GLOBAL_SKILLS" | tr ' ' '\n' | grep -v '^_template$' | grep -v '^$' | sort)

# Missing: in registry but not in global almanac skills
MISSING_GLOBAL_SKILLS=$(comm -23 <(echo "$REGISTERED_SKILLS") <(echo "$ALMANAC_GLOBAL_SKILLS"))

# Broken: symlink exists but target doesn't resolve
BROKEN_GLOBAL_SKILLS=$(find "$GLOBAL_CLAUDE/skills/" -maxdepth 1 -type l ! -exec test -e {} \; -printf '%f\n' 2>/dev/null | sort)

# Stale almanac entries: in global almanac set but not in registry
STALE_GLOBAL_SKILLS=$(comm -13 <(echo "$REGISTERED_SKILLS") <(echo "$ALMANAC_GLOBAL_SKILLS"))

# --- Agents ---
if [ -L "$GLOBAL_CLAUDE/agents" ] || [ -d "$GLOBAL_CLAUDE/agents" ]; then
  GLOBAL_AGENT_STATUS="OK"
  test -d "$GLOBAL_CLAUDE/agents" || GLOBAL_AGENT_STATUS="BROKEN"
  GLOBAL_AGENT_COUNT=$(ls "$GLOBAL_CLAUDE/agents/"*.md 2>/dev/null | wc -l)
else
  GLOBAL_AGENT_STATUS="MISSING"
  GLOBAL_AGENT_COUNT=0
fi

# --- Teams ---
# Teams are NOT symlinked. TeamCreate uses ~/.claude/teams/ for runtime state.
# A ~/.claude/teams symlink is a misconfiguration — warn if found.
if [ -L "$GLOBAL_CLAUDE/teams" ]; then
  GLOBAL_TEAM_STATUS="MISCONFIGURED"
  GLOBAL_TEAM_COUNT=0
  # Stale symlink — should be removed to avoid collision with TeamCreate
else
  GLOBAL_TEAM_STATUS="OK"
  GLOBAL_TEAM_COUNT=0
fi
```

**Got:** Zero missing almanac skills, zero broken. External content (peon-ping, etc.) is listed but not flagged as errors.

**If fail:** If `~/.claude/` does not exist, the global hub is not set up. Refer to the [symlink-architecture guide](../../guides/symlink-architecture.md) for initial setup.

### Step 5: Generate Audit Report

Produce a summary table covering both layers.

```markdown
# Discovery Symlink Audit Report

**Date**: YYYY-MM-DD
**Almanac**: <almanac_path>
**Scope**: both | project | global

## Summary

| Content | Registered | Project | Global (almanac) | Global (external) |
|---------|------------|---------|-------------------|-------------------|
| Skills  | N          | N       | N                 | N                 |
| Agents  | N          | STATUS  | STATUS            | —                 |
| Teams   | N          | STATUS  | STATUS            | —                 |

## Issues

### Missing (registered but no symlink)
- Project skills: [list or "none"]
- Global skills: [list or "none"]

### Broken (symlink exists, target gone)
- Project: [list or "none"]
- Global: [list or "none"]

### Extraneous
- Stale almanac (in discovery but not registry): [list or "none"]
- _template in discovery path: [yes/no]
- External content (non-almanac): [list — informational only]
```

**Got:** A clear, actionable report. Zero issues means a clean bill of health.

**If fail:** If report generation itself fails, output raw counts and lists to the console as fallback.

### Step 6: Repair (Optional)

If `fix_mode` is `auto` or `interactive`, fix the issues found.

**6a. Create missing project symlinks:**
```bash
for skill in $MISSING_PROJECT_SKILLS; do
  ln -s "../../skills/$skill" "$PROJECT_CLAUDE/skills/$skill"
done
```

**6b. Create missing global symlinks:**
```bash
for skill in $MISSING_GLOBAL_SKILLS; do
  ln -s "$ALMANAC_PATH/skills/$skill" "$GLOBAL_CLAUDE/skills/$skill"
done
```

**6c. Remove broken symlinks:**
```bash
# Project
for broken in $BROKEN_PROJECT_SKILLS; do
  rm "$PROJECT_CLAUDE/skills/$broken"
done

# Global
for broken in $BROKEN_GLOBAL_SKILLS; do
  rm "$GLOBAL_CLAUDE/skills/$broken"
done
```

**6d. Remove stale almanac entries:**
```bash
# Only remove items that target the almanac path but aren't in the registry
for stale in $STALE_GLOBAL_SKILLS; do
  rm "$GLOBAL_CLAUDE/skills/$stale"
done

# Remove _template if present
rm -f "$GLOBAL_CLAUDE/skills/_template"
rm -f "$PROJECT_CLAUDE/skills/_template"
```

**6e. Fix missing directory symlinks (agents/teams):**
```bash
# Project agents
if [ "$PROJECT_AGENT_STATUS" = "MISSING" ]; then
  ln -s ../agents "$PROJECT_CLAUDE/agents"
fi

# Project teams
if [ "$PROJECT_TEAM_STATUS" = "MISSING" ]; then
  ln -s ../teams "$PROJECT_CLAUDE/teams"
fi

# Global agents
if [ "$GLOBAL_AGENT_STATUS" = "MISSING" ]; then
  ln -s "$ALMANAC_PATH/agents" "$GLOBAL_CLAUDE/agents"
fi

# Global teams
if [ "$GLOBAL_TEAM_STATUS" = "MISSING" ]; then
  ln -sf "$ALMANAC_PATH/teams" "$GLOBAL_CLAUDE/teams"
fi
```

**Important:** Never remove items classified as external. These belong to other projects (e.g., peon-ping) and must be preserved.

**Got:** All missing symlinks created, all broken symlinks removed, all stale almanac entries cleaned. External content untouched.

**If fail:** If `ln -s` fails due to an existing file/directory at the target path (e.g., empty directory instead of symlink), remove the blocker first with `rmdir` (for empty dirs) or flag for manual review (for non-empty dirs).

### Step 7: Verify

Re-run the audit checks from Steps 3-4 to confirm repairs.

```bash
echo "=== Post-repair verification ==="
echo "Project skills: $(ls "$PROJECT_CLAUDE/skills/" 2>/dev/null | grep -v '^_template$' | wc -l)"
echo "Global skills (almanac): $(echo "$ALMANAC_GLOBAL_SKILLS" | wc -w)"
echo "Broken project: $(find "$PROJECT_CLAUDE/skills/" -maxdepth 1 -type l ! -exec test -e {} \; -print 2>/dev/null | wc -l)"
echo "Broken global:  $(find "$GLOBAL_CLAUDE/skills/" -maxdepth 1 -type l ! -exec test -e {} \; -print 2>/dev/null | wc -l)"
echo "Project agents: $PROJECT_AGENT_STATUS ($PROJECT_AGENT_COUNT .md files)"
echo "Global agents:  $GLOBAL_AGENT_STATUS ($GLOBAL_AGENT_COUNT .md files)"
echo "Project teams:  $PROJECT_TEAM_STATUS ($PROJECT_TEAM_COUNT .md files)"
echo "Global teams:   $GLOBAL_TEAM_STATUS ($GLOBAL_TEAM_COUNT .md files)"
```

**Got:** Zero missing, zero broken. Counts match registered totals (for almanac content). External content listed separately.

**If fail:** If issues remain after repair, report the specific failures. Common causes: permission errors on `~/.claude/`, NTFS path length limits on `/mnt/` paths, or a non-empty directory blocking symlink creation.

## Validation

- [ ] Almanac path correctly identified and contains all three registries
- [ ] Registry counts match `total_*` header values (or discrepancy noted)
- [ ] Project-level skills, agents, and teams audited
- [ ] Global-level skills, agents, and teams audited
- [ ] External content (non-almanac) identified and excluded from issue counts
- [ ] `_template` entries flagged as extraneous (never belongs in discovery paths)
- [ ] Audit report generated with clear counts and actionable lists
- [ ] If `fix_mode` is `auto`: all safe repairs applied, external content untouched
- [ ] Post-repair verification confirms zero missing, zero broken

## Pitfalls

1. **Confusing external content with missing almanac content**: `~/.claude/skills/` may contain skills from other projects (e.g., peon-ping). Always check whether a symlink target is under the almanac path before classifying it as stale or extraneous.

2. **Removing external content**: Never delete items that don't target the almanac. They belong to other projects and are intentional.

3. **Symlinking `_template` directories**: Templates are scaffolding, not consumable content. The `_template` directory should never appear in `.claude/skills/` or `.claude/agents/`. Bulk sync scripts must explicitly skip it.

4. **Stale `.claude/teams` symlink**: A `.claude/teams` symlink pointing to team definitions is a misconfiguration. Claude Code's `TeamCreate` uses `~/.claude/teams/` for runtime state (config.json, inboxes). If this path is a symlink to the almanac's `teams/` directory, runtime artifacts will be written into the git-tracked repository. Remove any `.claude/teams` symlink found at project or global level.

5. **Relative vs absolute paths**: Project-level skill symlinks use relative paths (`../../skills/<name>`). Global symlinks use absolute paths (`/path/to/almanac/skills/<name>`). Mixing these patterns causes breakage on moves.

6. **Registry header vs actual count**: The `total_skills` field in the registry header may be stale if someone added entries without updating the count. Trust the actual `- id:` entries, not the header.
