developer

A development workflow agent for taking software changes from planning through implementation and review. It supports feature work, refactoring, quick fixes, and urgent production fixes.

In plain words
What is it for?
Use it to implement features from a specification and plan, restructure code, fix bugs, handle critical production issues, run build, lint, and test checks, open pull requests, and address reviewer feedback.
Why use it?
It gives different kinds of code changes an appropriate path, so small fixes do not require full planning and urgent fixes can start from the main code branch. It also checks the result and helps prepare the change for review.

Agent for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 75 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 3,458 The whole file, excluding the scripts and references it only reads on demand.

Origin unknown No closer match found in the catalogue.
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 B, and why

developer scanned grade B with 1 finding 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 2d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Before writing any code for documentation or policy changes, grep for all existing references to the policy being changed across `docs/`, `.cursor/`, `.claude/`, `.codex/`, `AGENTS.md`, `README.md`, `REVIEW.md` — do no

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.
