implement

implement is a skill for Claude Code from kaisa-kucherenko/claude-code-flow. It costs 140 tokens per session (4,157 once invoked), scanned A, original, MIT.

A guided workflow for completing one implementation phase from a written specification. It selects the next phase, explains the plan, runs the implementation, checks the changes, tests them, and records a commit.

In plain words
What is it for?
Use it to turn one specified phase into a reviewed, tested Git commit and update the project's handoff record.
Why use it?
It keeps a multi-phase change from losing track of what comes next or skipping review and testing. The project handoff supplies the commands and phase details instead of making the workflow guess.

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 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.

How it starts

The opening of the file, as written. The whole thing — 244 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement — run one phase of a spec

The spec says what; this skill is how a phase moves from text to a commit without the user losing the thread. One invocation = one phase.

Prerequisites

A Linux or macOS shell with ss (or lsof — adjust the port checks), setsid, and a scripted browser (playwright) for browser rows. <scratchpad> is the session's temporary directory — any per-session temp path works, it only has to survive the phase. The project's CLAUDE.md must name its stack start command, its ports, its health endpoint and its test/lint/build commands: this skill runs them, it does not guess them.

0. Which phase — the handoff decides

Main flow (/implement, no number): read the live handoff (HANDOFF_*.md in the project root; several → the one whose topic matches the current branch/issue). Its NEXT names the next phase and the spec path; the handoff's done-section («Зроблено» in a Ukrainian handoff — the heading follows the handoff's language) lists the phases already committed. If NEXT does not name the spec path, look in the handoff's Artifacts section; still nothing → ask before launching, do not guess. Cross-check against the spec index's phase map and git log on the branch — a phase marked done in the handoff but absent from the log (or the reverse) is a divergence: say so, stop.

Spec index = the single spec file (<topic>-spec.md) or the directory's README.md — whichever the spec has; it carries the preamble, the Ground rules and the phase map, and it is where a phase gets marked done (step 7).

Alternative (/implement N): the user names the phase. Still read the handoff for the spec path and the done-list; if N's dependencies are not done, say so, stop.

No handoff → the spec index's map is the only source; say that the handoff is missing and offer /handoff before continuing.

Spec location: the path in the handoff; else <topic>-spec.md or <topic>-spec/README.md next to the ADR (project root, or docs/adr/<domain>/ for a split ADR). Phase file: NN-<name>.md or the ## Phase N section.

implement is a skill published in the GitHub repository kaisa-kucherenko/claude-code-flow (23 stars, last pushed 4d ago), licensed MIT. It adds 140 tokens to every session and 4,157 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-19.
