specmanager: Instructions file for Claude Code

CLAUDE.md

specmanager CLAUDE.md is an instructions file for Claude Code from joanseg/specmanager. It costs 4,834 tokens per session, scanned A, original, MIT.

Project instructions for SpecManager, a tool that tracks product features through stages such as approved design documents and implementation. They explain where specifications live and how their lifecycle is managed.

In plain words
What is it for?
Reviewing feature specifications, checking lifecycle stages, and implementing work according to the approved project documents.
Why use it?
They help an agent determine which requirements are approved before changing a feature.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions subagents.

This is joanseg/specmanager's own configuration. It tells Claude Code how to work on specmanager itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything specmanager configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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

specmanager CLAUDE.md scanned grade A with 1 finding 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 14d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

**A surface test is also required when the release changes packaging** — anything in `plugin.json` beyond the `version` bump, `.mcp.json`, `hooks/`, the plugin-root `package.json` / `package-lock.json`, `ui/vite.config.t

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.
