specrate

specrate is a skill for Claude Code, Codex from rickygao/specrate. It costs 20 tokens per session (546 once invoked), scanned A, original, Apache-2.0.

A system for managing software specifications and proposed changes in structured documents. It covers the full path from proposing and planning a change to implementing and archiving it.

In plain words
What is it for?
Use it to show specification status, propose or amend changes, plan and implement approved work, archive completed changes, or correct specifications to match the codebase.
Why use it?
It gives teams a defined way to track what the system should do, why it is changing, and which changes are complete.

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

specrate 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.

Specrate

Overview

The specrate system is designed to manage specs and changes to those specs in a structured manner. It provides a framework for proposing, planning, implementing, and archiving changes to the system's specs.

  • PRINCIPLE.md must be read first to understand how specrate works.
  • actions folder defines detailed steps for each specrate action.
  • templates folder contains templates for various specrate artifacts and reports.

Decisions

Based on the user's request, decide which action to take.

  • If the user intends to show the current status of specs and changes, follow SHOW-STATUS.md action.
  • If the user intends to propose a new change, follow PROPOSE-CHANGE.md action.
  • If the user intends to amend an existing change, follow AMEND-CHANGE.md action.
  • If the user intends to plan a proposed change, follow PLAN-CHANGE.md action.
  • If the user intends to implement a planned change, follow IMPLEMENT-CHANGE.md action.
  • If the user intends to archive an implemented change, follow ARCHIVE-CHANGE.md action.
  • If the user intends to fix a spec according to the codebase, follow FIX-SPEC.md action.
  • If the user's intent mixes multiple actions, break down the intent into individual actions, ask for confirmation, and execute them one by one.
  • If the user's intent is ambiguous (e.g., “update the spec”), ask a clarifying question with possible options to determine the specific action needed.

Disciplines

  • Always ask for clarifications if needed, and ensure the workspace remains consistent after each step. When asking for clarifications, provide concise options to the user if applicable.
  • All specrate-managed artifacts that this skill creates/updates in the user's repository MUST reside in the .specrate/ folder at the repository root.
  • Do NOT create auxiliary documents (README, index, etc.) outside .specrate/ unless explicitly instructed by the user.

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.
