gaia-spec

gaia-spec is a command for Claude Code from gaia-react/gaia. It costs 0 tokens per session (167 once invoked), scanned A, original, MIT.

A guided workflow for writing an unchanging project specification, meaning a shared description of what should be built and why. It uses questions to discover the requirements, then stops and prints a prompt for a separate planning step.

In plain words
What is it for?
Use it to create a GAIA specification through interactive questions, or use its automatic mode when no person needs to answer the questions.
Why use it?
It separates agreeing on requirements from deciding how to implement them, reducing accidental planning before the specification is settled.

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

gaia-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 5d 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

Run the GAIA spec workflow with these arguments: $ARGUMENTS

Read .claude/skills/gaia/references/spec.md from the project root and follow it exactly. That reference is written to consume an argument string, treat the arguments above as that input (including a leading auto token, which the reference detects). If no arguments were provided, follow the reference's no-argument path.

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.
