specify

specify is a skill for Claude Code, Codex from andyrids/icm-spec. It costs 25 tokens per session (199 once invoked), scanned A, original, Apache-2.0.

A specification workflow that turns a feature request into a proposed specification change, implementation plan, and technical specification. It follows the project's ICM stage 01 process and pauses for approval before implementation.

In plain words
What is it for?
Preparing feature specifications and plans in projects that use the ICM process.
Why use it?
It creates a reviewed technical agreement before code is changed, reducing ambiguity about what should be built.

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

specify 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 3d 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

ICM stage 01 - specification

The argument is the feature request. If it is empty, ask for one before doing anything else.

  1. Read CONTEXT.md at the repository root, then ICM/process-plan/CONTEXT.md, then ICM/process-plan/stages/01-specification/CONTEXT.md. If any of these is missing, stop and suggest /icm:init.
  2. Execute the stage contract exactly as written - it defines the inputs, process and outputs.
  3. Stop at the workspace's review gate: present the spec change, the plan and the techspec for explicit user acceptance before any implementation begins. /icm:implement is the next step once accepted.

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.
