A repository-checking skill that verifies required files, documentation, task structure, skill metadata, Python syntax, and obvious secrets before handoff or publishing.

Use it after restoring a repository, changing tasks or skills, preparing a public copy, or validating files before delivery.

It catches missing files, broken structure, invalid scripts, and accidentally exposed secrets before the repository is shared or used.

repo-health — Skill for Claude Code and Codex by rdudov

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add rdudov/task-agent --skill repo-health

Clone the repo

git clone --depth 1 https://github.com/rdudov/task-agent

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.01023
Opus 5	$0.00028	$0.00511
Sonnet 5	$0.00011	$0.00205
Haiku 4.5	$0.00006	$0.00102

Security

Grade A, and why

repo-health scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/check_deliverables.py, scripts/check_pre_push.py, scripts/check_repo_health.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo Health

This skill checks whether the repository is structurally usable after restore or before handoff.

Scope

Use it when:

a backup restore may have lost local artifacts
a public/template copy is being prepared
task, data, or skill structure has changed
an agent-engine change needs a quick repository health gate

Checks

The bundled script validates:

required root files: AGENTS.md, README.md, .gitignore, requirements.txt, and requirements.lock
required docs: docs/architecture.md and docs/task-execution.md
every task directory has task.md and plan.md. The rebuildable task index is deliberately not checked: it is regenerated from tasks/ on demand, and tasks_index.py check owns the task-metadata properties
every skills/*/SKILL.md has name and description frontmatter
executable Python scripts parse in memory, so the check works on read-only checkouts and does not create __pycache__ entries
obvious secret-like content is absent from the files Git can publish: tracked files plus untracked, non-ignored files. The check reuses the pre-push guard's pattern definitions and fails closed if Git cannot establish that scope.

Ignored tasks/ and data/ contain durable local evidence, not publishable source. Repository health therefore does not scan those histories for secrets; check_pre_push.py still refuses real task/data artifacts in outgoing commits.

Command

.venv/bin/python skills/repo-health/scripts/check_repo_health.py

For a sanitized template that intentionally omits local task history:

.venv/bin/python skills/repo-health/scripts/check_repo_health.py --allow-empty-tasks

Pre-Push Leak Check

Run before pushing source changes to a configured remote:

.venv/bin/python skills/repo-health/scripts/check_pre_push.py --remote origin

The check scans outgoing files for local task/data/state artifacts, environment files, private keys, and common token formats. It is a guardrail, not a complete security scanner; still review the outgoing diff before pushing.

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

repo-health is a skill published in the GitHub repository rdudov/task-agent (4 stars, last pushed 2d ago), licensed MIT. It adds 55 tokens to every session and 1,023 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
