What is health-check?

A scheduled project check for Claude Desktop that reviews tests, diagnostics, security, and Git status. It runs hourly or daily when configured as a scheduled task.

Use it for regular project maintenance checks. It can review the current Git branch and changes, collect errors and warnings, run the test suite, and report other listed health checks.

It gathers common signs of project problems in one recurring check, so issues such as failing tests, warnings, security findings, or uncommitted changes are easier to notice.

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	$0.00000	$0.00626
Opus 5.5	$0.00000	$0.00250
Sonnet 5.5	$0.00000	$0.00125

Security

Grade A, and why

health-check 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 2mo ago.

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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Installation

Copy this template to your Claude Desktop scheduled-tasks directory:

mkdir -p ~/.claude/scheduled-tasks/health-check
cp /path/to/claude-ide-bridge/templates/scheduled-tasks/health-check/SKILL.md \
   ~/.claude/scheduled-tasks/health-check/SKILL.md

Then restart Claude Desktop to detect the new scheduled task. Configure the schedule in Claude Desktop settings under "Scheduled Tasks".

The bridge must be running when this task fires. Start it with claude-ide-bridge --watch or npm run start-all.

Emergency stop: Set CLAUDE_CODE_DISABLE_CRON=1 in your environment to immediately halt all scheduled cron jobs mid-session. Useful if a task runs amok or you need to suppress scheduled runs temporarily.

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.
