implement

A workflow for carrying out an approved, multi-step coding plan by sending each phase to a new helper agent and checking the result before continuing.

In plain words
What is it for?
Use it to implement planned features across several phases, with proportional checks after each phase and support for resuming partial work.
Why use it?
It keeps the main work session smaller and provides a clear way to continue unfinished work from the first pending phase.

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 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 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.

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

Run the dispatch loop on a worktree with an approved multi-phase plan.

Opt-in. Invoked after /agent-dashboard:feature (or a sibling task skill) probes the user at plan approval and the user picks "Hand off to /agent-dashboard:implement". Each phase dispatches to a fresh Agent() subagent, keeping the orchestrator session slim. Re-invoking on a partially-done worktree resumes from the first pending phase — no separate resume mode.

Instructions

Follow these phases in order. Each phase has a gate — do not proceed until the gate is satisfied.

If a dispatched phase touches browser UI, Playwright, dev-server ports, screenshots, or interactive Browser/Chrome inspection, include ../_shared/ui-automation.md in the subagent context and pass the resolved worktree-local UI resources explicitly.

Include ../_shared/verification-profiles.md in every subagent prompt so Verification profile names remain defined even when agent-dashboard is installed without external core rules.


Phase 1: Locate worktree + plan

  1. Confirm cwd is a worktree. Run git rev-parse --show-toplevel; the path must match .../worktrees/<app>/<name>. If not, halt: "Run this from inside a feature worktree, not the main checkout."

  2. Read .feature-plan-path from the worktree root. Its single line is the absolute path to the approved plan markdown:

    cat .feature-plan-path
    
  3. Fallback if the sentinel is missing (older /agent-dashboard:feature run, or deleted):

    • ls -lt ~/.claude/plans/*.md | head -5
    • Show the top 3 candidates via AskUserQuestion, including the current branch name in the prompt for context. User picks one or "Other" to type a path.
  4. Wait for env setup. Check the worktree root for the env sentinels:

    • .env-setup-done → proceed.
    • .env-setup-failed → surface contents, halt.
    • Neither → /agent-dashboard:feature Phase 2's background agent is still running. Wait.

Gate: Worktree confirmed, plan file path resolved, env setup complete.

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.

implement is a skill published in the GitHub repository bjornjee/agent-dashboard (21 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 2,220 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
