plan

A planning workflow for turning one software ticket idea into a defined piece of work. It questions the idea, investigates where the fix could belong, helps choose an approach, and files the ticket.

In plain words
What is it for?
Use it to plan new work, resume a ticket marked as needing planning, or examine an idea in detail before filing it.
Why use it?
It exposes unanswered questions and implementation choices before development begins.

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 B, and why

plan scanned grade B 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 2d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

3. **Unknown** - nothing readable settles it; grep `.claude/rules/` and auto-memory first, and cite a question already closed there rather than re-measuring it. Otherwise it is a spike.

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.
