speckit-implement

A workflow tool that creates a custom checklist from a feature's requirements. It treats the checklist as a review of how clear and complete the requirements are, not as a software test.

In plain words
What is it for?
Reviewing requirements for completeness, clarity, and consistency, such as checking whether visual or accessibility rules are defined. It is intended for the Speckit workflow mode.
Why use it?
It helps reveal missing, vague, or inconsistent requirements before implementation begins.

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

speckit-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.

Origin

This is a copy

77% identical to speckit-implement — 164 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Workflow Mode Guard

Use this skill only when the active local workflow mode is speckit.

Before proceeding:

  • Run ./scripts/hooks/workflow-mode.sh status.
  • If the active mode is superpowers, stop and tell the user to switch with make workflow-use mode=speckit or continue with the Superpowers workflow instead.
  • Do not mix speckit-* commands with Superpowers workflow skills in the same session or worktree.

You MUST adhere to the following mandatory requirements when implementing features.

Workflow context:

  • Input: tasks.md (actionable task list)
  • Output: Working code with passing tests
  • Verification: Execute Show & Tell steps after each phase

Base requirements: Follow all rules in copilot-instructions.md, particularly:

  • Repository tooling
  • Test-driven development
  • Repository verification policy

Prerequisite: This skill assumes tasks.md already exists. If tasks.md does not exist, stop and tell the user to run /speckit-tasks first.

Scope Notes

  • For infrastructure, scripts, documentation, or reporting tools, use lightweight validation that stays explicit and deterministic
  • If project setup or ignore-file guidance does not apply to the feature scope, skip that work instead of inventing application-style setup tasks

Implementation Process (Mandatory)

  1. Work through tasks in tasks.md sequentially
  2. For code tasks, follow TDD: write failing test first, then implement, then refactor
  3. After completing each phase or user story, execute its Show & Tell steps to verify correctness
  4. For infrastructure, scripts, documentation, or reporting tools, lightweight validation such as file presence, expected keys, or deterministic command output is sufficient
  5. Respect the repository's canonical local quality-gate policy after every source code change; where hooks enforce the gates automatically, do not duplicate the same gate commands manually unless diagnosing a failure

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.
