At a glance

Verify that Gemini CLI and Claude Code CLI are installed, authenticated, and API-reachable before starting collaboration workflows.

  • Documents & Office work in your project
  • SKILL.md covers When to use, When not to use, Inputs and Outputs, plus 4 more sections
  • Calls claude, gemini and npm; reaches docs.anthropic.com; needs GEMINI_API_KEY and GOOGLE_API_KEY

What it does

Check Collaborators is an agent skill from yunshenwuchuxun/latex-paper-skills. Verify that Gemini CLI and Claude Code CLI are installed, authenticated, and API-reachable before starting collaboration workflows.

Its SKILL.md is about 1.4k 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 Documents & Office. The repository describes itself as: A modular skill-based framework for writing, revising, and managing LaTeX academic papers with AI assistance. The licence is MIT.

When your agent uses it

  • Documents & Office work in your project

Example prompts

  • “/check-collaborators”

Requirements

  • Node.js
  • A credential in GEMINI_API_KEY
  • A credential in GOOGLE_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit d0f1061. 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:

    • claude
    • gemini
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • docs.anthropic.com

    Also links to:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • GEMINI_API_KEY
    • GOOGLE_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Check Collaborators loads about 1.4k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 557 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

Collaborator CLI health check

Collaborator CLI Health Check

When to use

  • Before starting any collaboration workflow that depends on Gemini or Claude Code.
  • When diagnosing CLI connectivity or authentication issues.
  • After installing or reconfiguring either CLI.

When not to use

  • Both CLIs are already confirmed working in the current session.
  • The task does not involve cross-agent collaboration.

Inputs

  • Current OS environment (auto-detected).

Outputs

  • Summary table: Collaborator x CLI / Version / Auth / API / Status.
  • Actionable remediation advice for any failed step.

Workflow

Run the Gemini and Claude detection chains in parallel where possible. For each collaborator, execute steps sequentially and short-circuit on the first failure — skip subsequent steps and mark the failure reason.

Step 0: Detect OS

Determine the platform to choose the correct binary-lookup command:

  • Windows (win32): use where
  • Unix/macOS: use which

Detect via uname -s 2>/dev/null (returns nothing or errors on Windows) or check $OSTYPE.

Gemini Detection Chain
1. CLI Exists
bash
# Unix
which gemini
# Windows
where gemini

Pass: command exits 0 and outputs a path. Fail: command not found — suggest: npm install -g @anthropic-ai/gemini-cli or see https://github.com/google-gemini/gemini-cli

2. Version
bash
timeout 15 bash -c 'GEMINI_CLI_NO_RELAUNCH=true gemini --version'

On Windows (no timeout command), run directly:

bash
GEMINI_CLI_NO_RELAUNCH=true gemini --version

GEMINI_CLI_NO_RELAUNCH=true is required to prevent the CLI from hanging.

Pass: output contains a version string (e.g., 0.32.1). Fail: timeout or no version output.

3. Auth

Check for any of the following (any one is sufficient):

  1. Environment variable GEMINI_API_KEY is set and non-empty.
  2. Environment variable GOOGLE_API_KEY is set and non-empty.
  3. File ~/.gemini/oauth_creds.json exists.
bash
[[ -n "$GEMINI_API_KEY" ]] || [[ -n "$GOOGLE_API_KEY" ]]
test -f "$HOME/.gemini/oauth_creds.json"

Pass: any one condition is true. Fail: none found — suggest: export GEMINI_API_KEY=<key> or run gemini interactively to complete OAuth.

4. API Connectivity
bash
timeout 30 gemini --prompt "Reply with exactly: HEALTH_OK"

Pass: stdout contains HEALTH_OK. Fail: timeout or no HEALTH_OK in output — suggest checking network, API key validity, or quota.

Note: Gemini CLI may emit warnings (e.g., skill conflict notices) in its output. These are benign and do not affect the health check. The pass/fail criterion is solely whether HEALTH_OK appears in stdout.

Claude Code Detection Chain
1. CLI Exists
bash
# Unix
which claude
# Windows
where claude

Pass: command exits 0 and outputs a path. Fail: command not found — suggest: npm install -g @anthropic-ai/claude-code or see https://docs.anthropic.com/en/docs/claude-code

Show full SKILL.md (225 more words)Show less
2. Version
bash
timeout 15 claude --version

Pass: output contains a version string (e.g., 2.1.74). Fail: timeout or no version output.

3. Auth
bash
claude auth status

Pass: output contains Logged in or JSON field loggedIn: true. Fail: not logged in — suggest: run claude interactively and use /login.

4. API Connectivity
bash
timeout 30 claude --print "Reply with exactly: HEALTH_OK" --output-format text --no-session-persistence --max-budget-usd 0.50

Pass: stdout contains HEALTH_OK. Fail: timeout or no HEALTH_OK — suggest checking API key, network, or account quota.

Note: --max-budget-usd must be at least 0.50. Lower values (e.g., 0.01, 0.05) cause immediate Exceeded budget errors because model inference has a minimum cost floor.

Output Format

Present a summary table after all checks:

| Collaborator | CLI | Version | Auth | API | Status    |
|--------------|-----|---------|------|-----|-----------|
| Gemini       | ✓/✗ | x.y.z   | ✓/✗  | ✓/✗ | Available / Failed |
| Claude Code  | ✓/✗ | x.y.z   | ✓/✗  | ✓/✗ | Available / Failed |
  • Use ✓ for passed steps, ✗ for failed steps, — for skipped steps (due to short-circuit).
  • Status is Available only if all 4 steps pass; otherwise Failed.
  • Version column shows the detected version string, or — if not reached.

For any failed step, append actionable remediation advice below the table:

### Issues Found

**Gemini — Auth failed**
No API key or OAuth credentials detected.
→ Set `GEMINI_API_KEY` environment variable, or run `gemini` to complete OAuth login.

**Claude Code — CLI not found**
Claude Code CLI is not installed.
→ Install: `npm install -g @anthropic-ai/claude-code`
→ Docs: https://docs.anthropic.com/en/docs/claude-code

If both collaborators pass all checks:

Both collaborators are available and ready for collaboration workflows.

Verification

  • Run this skill and confirm the summary table appears with correct status for each collaborator.

Safety and guardrails

  • Read-only checks only; no configuration files are modified.
  • API connectivity tests consume minimal tokens (~$0.01 per check).
  • Steps 2-4 spawn external CLI processes; run them outside sandbox (escalated permissions) to avoid hangs or EPERM errors.
  • On Windows, timeout may not be available; run commands directly and watch for hangs.
  • Gemini --version must use GEMINI_CLI_NO_RELAUNCH=true to prevent the CLI from relaunching itself.
