fp-implement

A workflow for finding, claiming, implementing, and completing software issues with the fp command-line tool. It also covers progress comments and issue dependencies.

In plain words
What is it for?
Use it to find the next task, mark work as started, report updates, implement changes, and close completed issues.
Why use it?
It gives agents a consistent way to choose work, show progress, and keep issue status accurate.

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.

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 C, and why

fp-implement scanned grade C with 2 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 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.

FP Implement Skill

Find, claim, and complete work on issues.

Prerequisites

Before using fp commands, check setup:

# Check if fp is installed
fp --version

If fp is not installed, tell the user:

The fp CLI is not installed. Install it with:

curl -fsSL https://setup.fp.dev/install.sh | sh -s
# Check if project is initialized
fp tree

If project is not initialized, ask the user if they want to initialize:

This project hasn't been initialized with fp. Would you like to initialize it?

If yes:

fp init

Core Workflow

1. Find work     → fp tree, fp issue list --status todo
2. Claim work    → fp issue update --status in-progress <PREFIX>-X
3. Do work       → implement the task
4. Comment often → fp comment <PREFIX>-X "progress update"
5. Complete      → fp issue update --status done <PREFIX>-X

Finding Work

See the Full Picture

fp tree

Shows all issues with hierarchy, status, and dependencies.

fp tree --status todo

Shows only todo items (filters out done work).

fp tree <PREFIX>-X

Shows a specific issue and its children - useful for focusing on one feature/epic.

List by Status

fp issue list --status todo          # Available to pick up
fp issue list --status in-progress   # Currently active
fp issue list --status done          # Completed
fp issue list                        # All issues

Pick the Right Task

Look for tasks that:

  • Have status todo
  • Have no dependencies, OR all dependencies are done
  • Match your current focus/expertise

Claiming Work

Mark as In-Progress

fp issue update --status in-progress <PREFIX>-2

This captures the current VCS state as the starting point for tracking changes.

Log That You're Starting

fp comment <PREFIX>-2 "Starting work. First step: implement the User model schema"

Load Context

fp context <PREFIX>-2

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.

fp-implement is a skill published in the GitHub repository fiberplane/claude-code-plugins (40 stars, last pushed 6mo ago), licensed MIT. It adds 42 tokens to every session and 1,434 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
