At a glance

Runs cozempic doctor to check Claude Code configuration and sessions for known problems such as trust-dialog hangs, corrupted tool blocks and zombie teams.

  • Troubleshooting Claude Code hooks that silently stop working
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Diagnosing 400 or 403 API errors in long sessions or agent teams
  • Cleaning up stale backups and team directories that take up disk space

What it does

The skill runs one command, `cozempic doctor`, and its name is chosen so it does not shadow Claude Code's built-in /doctor. The checks cover a Windows resume bug where a trust entry in .claude.json causes hangs, a missing hasTrustDialogHooksAccepted flag that makes hooks fail silently in v2.1.51 and later, subagents that do not inherit the team lead's model and trigger 403 errors, and a truncated or invalid .claude.json caused by concurrent write races.

It also looks at session data: tool_use blocks with names over 200 characters and tool_result blocks with no matching tool_use, both causing 400 API errors, sessions large enough to cause compaction issues, plus stale agent team directories, old .bak files and total Claude Code disk usage. Adding --fix to the command repairs the issues it detects automatically. The skill only permits Bash calls to the cozempic command.

When your agent uses it

  • Troubleshooting Claude Code hooks that silently stop working
  • Diagnosing 400 or 403 API errors in long sessions or agent teams
  • Cleaning up stale backups and team directories that take up disk space

Example prompts

  • “Run cozempic doctor and tell me what is wrong with my Claude Code setup.”
  • “My subagents keep failing with 403 errors, so check for model mismatches and fix what you can.”
  • “Run the cozempic health check with the fix option and report what changed.”

Requirements

  • The cozempic CLI installed and on the PATH
  • Pre-approved tools (allowed-tools): Bash(cozempic *)

What it can do on your machine

Read from SKILL.md and the folder at commit fd41e95. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(cozempic *)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Cozempic Doctor loads about 303 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 112 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~303

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.

description
Run health checks on Claude Code configuration and sessions. Use when troubleshooting Claude Code issues. (cozempic — does not shadow Claude Code's built-in /doctor)
allowed-tools
Bash(cozempic *)

Run cozempic health checks:

bash
cozempic doctor

Checks for:

  • Trust dialog hang — Windows resume bug where .claude.json trust entry causes hangs
  • Hooks trust flag — missing hasTrustDialogHooksAccepted causing hooks to silently fail (v2.1.51+ bug)
  • Agent model mismatch — spawned subagents not inheriting team lead's model causing 403 errors
  • Claude.json corruption — truncated or invalid .claude.json from concurrent write races
  • Corrupted tool_use — tool blocks with names >200 chars causing 400 API errors
  • Orphaned tool_results — tool_result blocks missing matching tool_use causing 400 API errors
  • Zombie teams — stale agent team directories accumulating on disk
  • Oversized sessions — sessions that may trigger compaction issues
  • Stale backups — old .bak files consuming disk space
  • Disk usage — total Claude Code storage footprint

To auto-fix detected issues:

bash
cozempic doctor --fix
