spec

A command that starts a guided process for describing a software feature and refining its requirements through questions.

In plain words
What is it for?
It helps draft an initial specification, ask clarifying questions, check the result, run a review, and hand the work to the planning process.
Why use it?
It removes ambiguity before planning or building, so important details and decisions are recorded early.

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 A, and why

spec 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.

What it actually says

/speckit-gaia-spec, thin redirect to the GAIA router

This command exists because spec-kit's extension manifest schema requires provides.commands[] to be non-empty, and because the three GAIA hook targets (speckit.gaia.constitution-check, speckit.gaia.lint, speckit.gaia.self-review) need an extension to anchor them to. The canonical user-facing entry point for the GAIA Socratic discovery flow is /gaia-spec, which lives alongside /gaia-plan, /gaia-handoff, /gaia-pickup, and /gaia-audit as the GAIA workflows.

Dispatch

Read .claude/skills/gaia/references/spec.md and follow it, treating $ARGUMENTS as the feature description.

That reference is the single source of truth for the orchestration: pre-flight, /speckit-specify, gate 1, GAIA's Socratic clarify loop, the self-review, gate 2, the after_specify lint, save, and the /gaia-plan handoff prompt.

Why this is one line

Two doors into the same orchestrator:

Door Layer Body
/gaia-spec Command (.claude/commands/gaia-spec.md) Reads $ARGUMENTS, dispatches to references/spec.md.
/speckit-gaia-spec Auto-generated by specify extension add This file. One-line redirect to the same references/spec.md.

Never duplicate orchestration logic into this file. The drift cost between two parallel orchestrators outweighs the convenience. One source of truth (references/spec.md); two doors into it.

Changes

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.

spec is a command published in the GitHub repository gaia-react/gaia (22 stars, last pushed 2d ago), licensed MIT. It adds 30 tokens to every session and 417 once invoked, about $0.0002 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.
