Auto-Sync

Mode Detection

EXECUTE using Bash tool (args: $ARGUMENTS):

bash "${CLAUDE_SKILL_DIR}/scripts/detect-mode.sh" $ARGUMENTS

Parse output: MODE|ARG|FLAGS. If exit code non-zero → report error, EXIT.

Mode	Trigger	Scope
STATUS	status	Report INDEX state → EXIT
INIT	init <path>	Tag file + add to INDEX → EXIT
GLOBAL	global	~/.claude/** (excludes managed dirs)
PROJECT	empty	.claude/** (excludes managed dirs)
FILE	file path	Single file
FOLDER	folder path	All .md in folder

Managed directories (excluded from auto-scan, explicit path required):

• rules/ — sync via /brewdoc:auto-sync .claude/rules
• agents/ — sync via /brewdoc:auto-sync .claude/agents
• skills/ — sync via /brewdoc:auto-sync .claude/skills

INDEX Format

{"p":"skills/auth/SKILL.md","t":"skill","u":"2026-02-05","pr":"default"}

Field	Description
p	Relative path
t	Type: skill/agent/rule/config/doc
u	Last sync date (YYYY-MM-DD)
pr	Protocol: default/override

Paths: Project .claude/auto-sync/INDEX.jsonl | Global ~/.claude/auto-sync/INDEX.jsonl

Frontmatter Fields

Required (3):

auto-sync: enabled
auto-sync-date: 2026-02-05
auto-sync-type: skill

Optional override (multiline YAML):

auto-sync-override: |
  sources: src/**/*.ts, .claude/agents/*.md
  focus: API endpoints, error handling
  preserve: ## User Notes, ## Custom Config

Override Field

When auto-sync-override: present in frontmatter → INDEX gets pr: "override".

Stored in frontmatter only — never in document body.

1. Read INDEX.jsonl, verify indexed files exist
2. Find all .md files in scope
3. Compare indexed vs found → identify non-indexed
4. Detect type for non-indexed (discover.sh typed) — output: TYPE|PATH per line
5. Output report: Indexed (path, type, protocol, last sync, stale), Non-Indexed (path, detected type, reason), Summary (counts)
6. EXIT

Input: init <path>

1. Read <path> — if NOT found → error, EXIT
2. If has auto-sync: enabled → "Already tagged", EXIT
3. Detect type via discover.sh
4. Add frontmatter: auto-sync: enabled, auto-sync-date: {today}, auto-sync-type: {type}
5. Check frontmatter auto-sync-override: → set pr: override|default
6. Add to INDEX.jsonl
7. Output: path, type, protocol; EXIT

Sync Mode (PROJECT/GLOBAL/FILE/FOLDER)

Phase 1: Setup INDEX

EXECUTE using Bash tool:

SCOPE="project"  # or "global"
INDEX_DIR=".claude/auto-sync"
[ "$SCOPE" = "global" ] && INDEX_DIR="$HOME/.claude/auto-sync"
mkdir -p "$INDEX_DIR" && INDEX_FILE="$INDEX_DIR/INDEX.jsonl" && touch "$INDEX_FILE"
echo "INDEX=$INDEX_FILE"

Phase 2: Discover + Queue (load config: INTERVAL_DAYS, PARALLEL_AGENTS from .claude/tasks/cfg/brewdoc.config.json)

1. Find tagged files — EXECUTE using Bash tool:

bash "${CLAUDE_SKILL_DIR}/scripts/discover.sh" "$SCOPE_PATH" typed

Output: TYPE|PATH per line (types: skill, agent, rule, config, doc). Capped at MAX_FILES (default 50).

2. For each file not in INDEX → auto-add:

   • Read file, use type from discover output
   • If no frontmatter → add auto-sync: enabled, auto-sync-date, auto-sync-type
   • Check <auto-sync-override> → set pr
   • Add to INDEX (index-ops.sh add)

3. Find stale entries — EXECUTE using Bash tool:

bash "${CLAUDE_SKILL_DIR}/scripts/index-ops.sh" stale "$INDEX_FILE" "$INTERVAL_DAYS"

4. Queue: new + stale files

Phase 3: Process + Report

1. Launch bd-auto-sync-processor agents (max PARALLEL_AGENTS batches, model="sonnet"):

   Task(subagent_type="brewdoc:bd-auto-sync-processor",
        prompt="PATH: {path} | TYPE: {type} | FLAGS: {flags}")
   

   Context: BD_PLUGIN_ROOT is injected into agent prompt by pre-task.mjs hook.

2. For each result:

   • If status = updated or unchanged → update INDEX u to today (index-ops.sh update)
   • If status = error → log to Errors table, do NOT update INDEX (file remains stale for retry)

3. Output report:
