speckit-coach is a skill for Claude Code, Codex from racecraft-lab/racecraft-plugins-public. It costs 80 tokens per session (1,403 once invoked), scanned A, original, MIT.

A coaching workflow for SpecKit and Spec-Driven Development, a method of planning software with written specifications before implementation. It explains the method, checklist areas, and common validation problems.

In plain words
What is it for?
Use it to learn the workflow, choose checklist areas such as security or data integrity, improve acceptance criteria, and troubleshoot validation gates.
Why use it?
It helps developers understand how to use SpecKit and diagnose rejected specifications or failed planning checks.

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-coach 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 yesterday.

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

SpecKit Coach

Coach the user through the official SpecKit CLI and complementary SpecKit Pro workflows. This skill provides guidance and bounded project repair; it does not run an autonomous workflow itself. In Codex, use $skill-name syntax for plugin skills rather than legacy custom slash-command syntax.

Start with the project that exists

  • Use speckit-pro/skills/speckit-autopilot/references/capability-discovery.md for capability selection and speckit-pro/skills/speckit-autopilot/references/grounding.md for external-fact grounding.
  • Discover the session's available tools and skills before recommending an external action. Ground external claims in an observed result; say when the available evidence is insufficient.
  • Inspect .specify/presets/*/preset.yml and .specify/extensions/*/extension.yml when present. Read the installed configuration before advising, so the advice reflects the project's actual constraints.
  • Treat mutable actions as user-controlled. Explain the intended change and request confirmation before installing, removing, enabling, disabling, or configuring extensions.

Route the request

Use the smallest relevant reference; do not load the whole library.

User goal Read or do
Learn SDD, start a project, recover from a failed phase, or assess artifacts Getting started and SDD methodology as needed.
Use an installed official Spec Kit command Command guide for inputs, artifacts, mistakes, and recovery. Inspect the active installed command definition for version-specific mechanics. For gate questions, read the live autopilot contract as a reference only; do not execute or invoke it.
Choose or author checklists Checklist domains. Read the feature's spec.md and plan.md, rank the relevant risks, and offer enriched prompts for two to four domains.
Decide whether a behavior needs formal verification, choose a checker, or learn a first model Selective formal methods. Assess risk and simpler checks first; record explicit selection and adapt coaching to experience.
Design a constitution Constitution guide.
Create or repair .specify/quality-gates.json, pick gate thresholds, or record a permanent gate skip Quality gates guide. Measure the existing code before proposing a ceiling; write the file only after the operator confirms.
Design a multi-spec roadmap or split a feature Technical-roadmap template and slicing heuristics. Derive independently executable vertical slices with observable outcomes and explicit real dependencies; review the graph before writing.
Create a PRD and roadmap from an unformed idea Route to $speckit-prd; use its PRD and roadmap templates.
Track one spec through phases or understand scaffold-created workflow files Workflow template. For scaffold creation, population, inputs, or output locations, also read the live scaffold skill as a reference only; do not execute or invoke it. Keep artifacts, gates, and decisions current.
Explain the roadmap home note Roadmap-MOC guide. The curated zone is author-owned; the generated index is regenerated, not hand-edited.
Explain or configure presets, extensions, hooks, catalogs, or upgrade recovery Presets and extensions guide. Discover and inspect first; confirm before any mutation.
Explain autonomous execution, consensus, remediation, review loops, or configuration Read the live autopilot skill as a reference only; explain its current contract without executing or invoking it.
Scope a raw brief interactively Route to $grill-me; do not conduct its interview here.
Scaffold a roadmap item, inspect status, resolve a review, or repair Codex agents Route respectively to $speckit-scaffold-spec, $speckit-status, $speckit-resolve-pr, or the SpecKit Pro install skill.
Archive merged-spec records or clean up archived specs Route to $speckit-archive-cleanup; do not copy or execute its cleanup workflow here.

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.
