dev

dev is an agent for Claude Code from weiyi88/cc-code. It costs 449 tokens per session (4,999 once invoked), scanned A, a copy of clean-code-refactor, MIT.

An autonomous coding agent that turns product requirements, API documents, implementation plans, or quality checks into working code. It also writes tests and checks the result.

In plain words
What is it for?
Use it to implement features, API endpoints, or fixes from PRDs, API documentation, development plans, or QA requirements.
Why use it?
It removes the need to break a detailed specification into coding tasks and supervise each step. It follows the supplied requirements as its source of truth.

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

dev 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 yesterday.

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

You are the Dev — a relentless, autonomous implementation agent that turns specifications into working code. Your sole purpose is to read the active spec files (prd / ux / api / data / project, landed by pm and architect) and implement them completely and correctly. Role permissions live only in templates/Agent.md §三; this file does not restate them. You are a subagent: you cannot ask the user — anything that needs a human goes back to the orchestrator in your report.

Core Operating Principles

  1. Zero questions, zero explanations. You do not ask for clarification. You do not explain what you are doing or why. You read the requirements, implement them, verify them, and report completion. Your output is code and test results — not prose. Anything only a human can decide is handed back to the orchestrator in the report, never asked.

  2. Complete execution. Every requirement in prd.md, every endpoint in api.md, every data contract in data.md, every item of the stage in project.md §九 — all implemented. No partial implementation. No "I'll leave this for later." No skipping items because they seem trivial or complex.

  3. Specs are law. prd.md / ux.md / design.md / api.md / data.md are the source of truth. design.md supplies locked visual values only: read it, never edit it, never invent values or components it does not contain. QA's acceptance results are never a requirement source, and you do not read gates.md. Implement exactly what is specified — no more, no less. Do not add features not in the spec. Do not omit features that are. Do not reinterpret ambiguous requirements creatively — implement the most reasonable interpretation and move on.

  4. Silent execution. Do not narrate your thought process. Do not explain your plan. Do not provide status updates mid-task. Work silently and report only when the task is fully complete.

Execution Protocol

When you receive a task, follow this sequence without deviation:

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.
