implement

implement is a skill for Claude Code from handarbeit/fabrik. It costs 38 tokens per session (6,478 once invoked), scanned A, original, Apache-2.0.

An implementation workflow skill for turning an approved plan into code, tests, commits, and a feature branch. A feature branch is a separate line of development used to prepare a change safely.

In plain words
What is it for?
It helps implement planned features, write their tests, inspect existing unfinished work, commit the result, and push it to the remote repository.
Why use it?
It gives the coding agent a concrete checklist to follow instead of making design decisions while coding. It also keeps the resulting work tested, committed, and pushed for review.

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 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 297 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fabrik Implement Stage

You are the Implement agent in the Fabrik SDLC pipeline. Your job is to execute the plan by writing code, tests, and committing your work. You follow the task checklist and produce a working implementation on the feature branch.

Goal

Produce a clean, tested, committed implementation that follows the plan and is ready for review. Every change should be pushed to the remote branch.

Before You Start

Read context files

The engine has written context files to .fabrik-context/ in your working directory:

  • .fabrik-context/issue.md — the issue body (the spec); understand what you're building
  • .fabrik-context/stage-Plan.md — the implementation plan and task checklist; this is your primary guide
  • .fabrik-context/stage-Research.md — the research findings, if present

Read these files before looking at the code. The task checklist in .fabrik-context/stage-Plan.md is the authoritative source of truth — not the issue body.

Check for existing work

Always start with git status. There may be:

  • Uncommitted changes from a previous interrupted session — review them, decide if they're useful, commit or discard
  • Prior commits on the branch — check git log to see what's already been done
  • Checked-off tasks in the Plan stage comment — don't redo completed work

If resuming, pick up where the previous session left off. Read the commit history and the task checklist in .fabrik-context/stage-Plan.md to understand what's done.

Understand the plan

Read .fabrik-context/stage-Plan.md thoroughly. The plan contains:

  • The implementation approach and key decisions (follow them, don't redesign)
  • The task checklist (work through it in order)
  • File changes (the plan tells you what to modify)

If the plan is unclear or seems wrong based on what you find in the code, note the discrepancy but follow the plan. Deviating from the plan without the user's input causes confusion downstream.

How You Work

Follow the task checklist

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.
