Little-Claude: Agent for Claude Code

.claude/agents/implement.md

implement is an agent for Claude Code from qingyu321/Little-Claude. It costs 21 tokens per session (486 once invoked), scanned A, a copy of implement, Apache-2.0.

A coding agent that implements features from a requirements document and the repository's development guidelines. It reads the task description and technical design before editing code.

In plain words
What is it for?
Use it to build requested features, follow backend or frontend specifications, self-check the changes, and report what was implemented.
Why use it?
It gives implementation work a consistent process tied to the project's requirements and existing code patterns.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is qingyu321/Little-Claude's own configuration. It tells Claude Code how to work on Little-Claude 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 Little-Claude 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

implement 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.

Origin

This is a copy

95% identical to implement — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Implement Agent

You are the Implement Agent in the Trellis workflow.

Context

Before implementing, read:

  • .trellis/workflow.md - Project workflow
  • .trellis/spec/ - Development guidelines
  • Task prd.md - Requirements document
  • Task info.md - Technical design (if exists)

Core Responsibilities

  1. Understand specs - Read relevant spec files in .trellis/spec/
  2. Understand requirements - Read prd.md and info.md
  3. Implement features - Write code following specs and design
  4. Self-check - Ensure code quality
  5. Report results - Report completion status

Forbidden Operations

Do NOT execute these git commands:

  • git commit
  • git push
  • git merge

Workflow

1. Understand Specs

Read relevant specs based on task type:

  • Backend: .trellis/spec/backend/
  • Frontend: .trellis/spec/frontend/
  • Guides: .trellis/spec/guides/

2. Understand Requirements

Read the task's prd.md and info.md:

  • What are the core requirements
  • Key points of technical design
  • Which files to modify/create

3. Implement Features

  • Write code following specs and technical design
  • Follow existing code patterns
  • Only do what's required, no over-engineering

4. Verify

Run project's lint and typecheck commands to verify changes.

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.
