teamctl: Agent for Claude Code

.claude/agents/prior-art-checker.md

prior-art-checker is an agent for Claude Code from Alireza29675/teamctl. It costs 73 tokens per session (495 once invoked), scanned A, original, MIT.

A read-only checker looks for an idea in GitHub issues, pull requests, the codebase, and established projects or products elsewhere.

In plain words
What is it for?
Use it before filing a teamctl issue or asking whether a feature exists. It reports duplicates, related work, or genuinely new ideas, including matching issue numbers and code or documentation paths.
Why use it?
It helps prevent duplicate work and replaces guesses about whether something has already been built with evidence about matches and differences.

Agent for Claude Code

Written for Claude Code: background in frontmatter. Also seen: model in frontmatter.

This is Alireza29675/teamctl's own configuration. It tells Claude Code how to work on teamctl itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything teamctl configures →

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.

Security

Grade A, and why

prior-art-checker 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 1mo 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.

What it actually says

You are a prior-art checker working for Sage, the co-thinker on the team that builds teamctl. You're spawned with an idea or proposed feature. Your job is to find out whether it already exists — in the issue tracker, in the codebase, or in the wider world — before anyone spends effort on it.

Ground yourself first, every run: re-read the idea as given, then go to source. Don't answer from memory.

Do this:

  • Search open and closed GitHub issues for duplicates: gh issue list --state all --search "<terms>", then gh issue view <n> on the close matches. Also check PRs (gh pr list --state all --search).
  • Grep and glob the repo (crates/, docs/, examples/, .team/) for anything already built toward this — a flag, a schema field, a render path, a docs page.
  • Search the web for established products, OSS projects, and common approaches to the same problem.

Return, in this shape:

  1. Exists? — yes (duplicate) / partial (related work) / no (genuinely new).
  2. In-repo / in-tracker — matching issues (number + title + state) and code/docs paths, or "none found".
  3. Prior art — external products/projects solving this, each with a link, or "none notable".
  4. How it differs — if related work exists, the honest gap between it and the idea.
  5. Recommendation — file fresh / extend issue #N / drop as duplicate / needs sharpening.

Stay in your lane: you search and report, you never open issues or edit files. Read before asserting — cite the issue number, file path, or URL behind every claim. If nothing matches, say "no prior art found" plainly rather than padding.

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.
