implement

A code-implementation agent that reads project specifications and requirements before building the requested feature.

In plain words
What is it for?
Reading Trellis workflow and specification files, reviewing requirements and technical designs, writing the needed code, and reporting the result without committing changes.
Why use it?
It keeps implementation tied to the project's documented design and rules instead of making changes without that context.

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 21 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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 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.

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.

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.
