What it does
Health Check is an agent skill from Jxck/sptth. Run a repository-wide maintenance pass before merge/release. Covers cleanup, formatting, tests, docs, security, and CI checks.
Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: reverse https proxy (https <- sptth) for local development. The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “/health-check”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Changed files
- What was auto-fixed
- What needs maintainer decision
- Validation results (fmt/test/check)
- Residual risks or follow-ups
What it can do on your machine
Read from SKILL.md and the folder at commit cd865e2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
cargo
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Health Check loads about 801 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 366 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

health-check Skill
Use this skill to run a repository-wide maintenance pass before merge/release.
Goal
Keep the repository clean, reproducible, and aligned across code, tests, CI, and documentation.
Scope
- Detect and remove unnecessary code/definitions/dependencies where safe.
- Ensure repository formatting is fully clean.
- Review dependency freshness and apply safe updates.
- Verify tests/build checks pass.
- Ensure markdown/docs reflect current behavior.
- Run security and release-readiness checks.
Required Procedure
- Baseline and inventory
- Check current git status and changed files.
- Identify generated/untracked artifacts that should not remain.
- Code and dependency cleanup
- Remove unused code/imports/definitions that are clearly dead.
- Review dependencies for obvious removals or outdated versions.
- Separate risky major upgrades from safe upgrades in reporting.
- Formatting and consistency
- Run repository formatting commands.
- Re-run format checks to confirm zero drift.
- Validation gates
- Run:
cargo run -p xtask -- fmt-checkcargo test -qcargo check --workspace
- Documentation sync
- Verify README/docs match current code behavior and defaults.
- Check command examples, config examples, option names, and stated limitations.
- Security pass
- Apply checklist from
skills/rust-security-checklist/SKILL.md:- input/resource limits
- trust boundary validation
- key/file handling
- command execution safety
- logging hygiene
- Compatibility and impact pass
- Confirm config compatibility implications are identified.
- Confirm
config.example.tomland docs are aligned with runtime behavior.
- CI reproducibility pass
- Ensure local validation commands match CI expectations.
- Flag workflow drift (missing checks, stale commands).
- Release readiness pass
Show full SKILL.md (143 more words)Show less
- Detect blockers for release quality:
- leftover generated artifacts
- stale docs
- unresolved TODOs that affect users
- broken or outdated command examples
- Language consistency pass
- Check for unintended Japanese text in repository files.
- Keep user-facing and project policy docs consistent with the repository language policy.
- Report intentional exceptions explicitly if any exist.
- Skill-policy conformance pass
- Verify that current code and workflow still conform to repository skills
(
sptth-dev,rust-error-handling,rust-testing,rust-security-checklist). - Identify mismatches between implemented behavior and skill guidance.
- Propose concrete remediation when drift is detected.
Output Format
Provide:
- Changed files
- What was auto-fixed
- What needs maintainer decision
- Validation results (fmt/test/check)
- Residual risks or follow-ups
Guardrails
- Prefer minimal safe edits; avoid broad refactors unless requested.
- Do not silently introduce breaking dependency upgrades.
- Keep commit scope coherent if committing.
- Follow commit format in
docs/commit-message.mdand keep commit text in English.
