gate-spec

gate-spec is a skill for Claude Code, Codex from orin-dx/agent-plugins. It costs 141 tokens per session (654 once invoked), scanned A, original, MIT.

A review gate for a software specification: a document that states what should be built and how success will be checked. It gives a pass or fail decision before the work is planned.

In plain words
What is it for?
Use it to check whether every acceptance criterion is testable, whether required specification details are present, and whether remaining issues should block planning.
Why use it?
It prevents vague requirements, unfinished decisions, or acceptance checks that cannot be tested from moving into implementation planning.

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

gate-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 today.

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

Scribe — Gate Spec

Without spec_file_path set, downstream agents fall back to reading the spec from conversation context, which is lossy under compression and cannot be independently verified.

2-Round Circuit Breaker: drafter ↔ auditor review loops (via scribe/draft-spec and scribe/audit-spec) are capped at 2 iterations before reaching this gate. On round 2, unresolved debates about internal helper names or line citations are demoted to non-blocking api_notes rather than looping further.

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.
