Maintenance Sweep

System-wide health check using agnix lint + a deterministic Python facts script + 3 parallel judgment sub-agents. Produces a consolidated report at log/audits/system-audit-YYYY-MM-DD.md. Report-only — never modifies any files.

Architecture note (2026-05-23): Sub-agents previously handled counts, broken-link detection, ecosystem inventory, and friends-repo file checks (SA1/SA4/SA5/SA7). They were unreliable — rolling their own counters, resolving links against the wrong CWD, recursing into the wrong directories — and produced false-positive findings that wasted triage cycles. Those four are now replaced by .scripts/system_audit_facts.py, which uses count_inventory.py as ground truth and resolves links against the source file's directory. The 3 remaining sub-agents (SA2 Bibliography, SA3 Conventions, SA6 Skill Quality) handle genuinely judgment-heavy work that can't be reduced to a script.

When to Use

• Periodic system hygiene (monthly or after major changes)
• When the user says "maintenance sweep", "system health check", "audit my setup"
• After adding/removing skills, hooks, agents, or rules
• Before presenting the system to others (ensure everything is consistent)

Overview

1. Lint — run npx agnix . + skill-numbering lint + review-agent logger-gate lint
2. Facts — run .scripts/system_audit_facts.py all --json (deterministic: counts, docs, ecosystem, friends repo)
3. Dispatch — launch 3 judgment sub-agents in parallel via the Task tool (SA2/SA3/SA6)
4. Collect — gather facts JSON + sub-agent findings
5. Consolidate — merge into a single timestamped report
6. Present — show key findings to the user

Python: Always use uv run python or uv pip install. Never bare python, python3, pip, or pip3. Include this in sub-agent prompts.

Autonomy

Per the global --autonomous / -y convention in ~/.claude/rules/phased-work.md § "Autonomy flag convention". Invoke as /system-audit --autonomous (or -y). When set:

• No inter-phase pauses — Lint → Dispatch → Collect → Consolidate → Present chain end-to-end.
• No AskUserQuestion mid-run — sub-agent count defaults to 3 (SA2/SA3/SA6), all sub-agents launch in parallel without confirmation.
• No interim "review and continue" pauses between dispatch and consolidation.
• Sub-agent forbid-list still applied — all 3 sub-agents are read-only (no edits to skills/hooks/agents/rules during the audit).
• Report-only invariant preserved — --autonomous does NOT change the skill's read-only nature; it only suppresses confirmation prompts. No fixes are ever applied.
• Single end-of-run report at log/audits/system-audit-YYYY-MM-DD.md is the only mandatory user-facing output.

This is one of the safer skills to run autonomously — it's read-only by design, sub-agents have no write access to the system, and the output is a single timestamped report that you can review afterward. Recommended for scheduled monthly runs via /scheduled-job.

Recommended invocations:

/system-audit --autonomous                              # full sweep, end-to-end
/system-audit -y                                        # short form

Phase 0: Pre-flight Lints

Two fast lint passes run in the main context before sub-agent dispatch. Both are summary-only — full findings feed into the final report.

0.1 agnix lint

Run npx agnix . and capture the summary line.

Pass criteria: 0 errors. Warnings are informational only.

If errors > 0, list them in the report under an agnix Lint section. These are structural issues in skill/hook/agent frontmatter that should be fixed.

Config lives in .agnix.toml at project root — known false positives are already suppressed.

0.2 skill-numbering lint

Run uv run python scripts/lint-skills.py and capture the summary line.

Pass criteria: 0 findings. Findings indicate phase-numbering smells, frontmatter typos, or stale cross-skill phase references. Reference: skills/_shared/skill-template.md § Anti-patterns.

If findings > 0, list them in the report under a Skill-Numbering Lint section. The linter explains each rule (R1–R9) inline.

0.3 review-agent logger-gate lint

Run:

grep -E "^After producing (DOMAIN-REVIEW|CODE-REVIEW|your verdict|your referee|the verification)" .claude/agents/*.md

Pass criteria: 0 matches. Any match means a review-agent definition is using the stale/fragile logger-gate intro pattern that was fixed by the 5-agent patch (commit 23ebcfff, 2026-05-17). The fragile pattern conditions the review-state-log.sh call on producing a stale top-level filename (DOMAIN-REVIEW.md-style) or a soft generic phrase ("your verdict", "the verification"); when orchestrators like /review-cluster send "Return findings as a structured list, NOT a file write", the gate fails and the helper never fires — leaving a logger gap detectable by /review-recap.

If matches > 0, list them in the report under a Review-Agent Logger-Gate section with the suggested replacement intro:

Write [your report] to reviews/<source-slug>/<YYYY-MM-DD-HHMM>.md (mkdir -p reviews/<source-slug>/ first). Then append a row to the project's REVIEW-STATE.md so /review-recap can render the run. Use the shared helper:

Reference pattern: see paper-critic.md line ~432 (already patched).

Phase 1: Deterministic Facts

Run the deterministic facts script in the main context. This replaces the four count/link/inventory sub-agents that were unreliable.

uv run python .scripts/system_audit_facts.py all --json > /tmp/system-audit/facts.json

What this covers (all deterministic — no LLM judgment needed):

Section	Replaces	What it checks
inventory	SA1 Inventory Auditor	Skill/hook/agent/rule counts vs count_inventory.py ground truth, symlinks, file-extension sanity
docs	SA4 Documentation Freshness	Stale counts in CLAUDE.md/README/docs, broken markdown links (resolved against source-file dir, not CWD), .context/ mtime freshness
ecosystem	SA5 Ecosystem Health	MCP server registry alignment, orphan tool references, CLI tool presence
friends	SA7 Friends Repo Health	Friends-repo skill/rule freshness vs upstream, anonymisation hygiene, install script presence

Why this is deterministic-only, not a sub-agent:

• Counts have a single source of truth (count_inventory.py) — re-rolling them in an LLM produces drift.
• Broken-link detection requires resolving relative paths against the source file's directory; sub-agents have variable CWD and produce false positives.
• Friends-repo file checks are presence/diff operations, not judgment.

If the script fails (exit code != 0), capture stderr in the report under a Facts Script Failure section and continue with sub-agent dispatch — the audit degrades gracefully but is no longer authoritative on the deterministic sections.

Phase 2: Dispatch Judgment Sub-Agents

Launch 3 in a single message using parallel Task tool calls. Each sub-agent is subagent_type: Explore.

Context overflow prevention: Instruct each sub-agent to keep its returned output concise — summary tables and key findings only (under 500 words). If detailed findings are large, the sub-agent should write them to a temp file (e.g., /tmp/system-audit/sa-N.md) and return only the file path + summary.

All sub-agents receive shared context (Task Management root, research projects root, category directories). Full shared context block and the 3 sub-agent prompt templates:

references/sub-agent-prompts.md

Sub-agents at a glance:

#	Name	What it checks
2	Bibliography & Project Hygiene	.bib files, naming, MEMORY.md presence
3	Convention Compliance	LaTeX out/, Overleaf separation, Python env, git health
6	Skill Quality & Overlap	Bloat, staleness, cross-component overlap

Sub-agent numbering retained from the old 7-agent fan-out so prompts and reports stay cross-referenceable. SA1/SA4/SA5/SA7 are now handled by .scripts/system_audit_facts.py in Phase 1.

---

Phase 3: Collect and Consolidate

After the 3 sub-agents return, merge their findings + the Phase 1 facts JSON into a single report.

Error Handling

• Sub-agent timeout: If a sub-agent doesn't return, note "timed out" in the report and continue with the others.
• Missing directories: If a category folder is empty or doesn't exist, note "no projects found" rather than erroring.
• Permission issues: If files can't be read, note "access denied" and continue.
