What is spectre CLAUDE.md?

A repository guide for spectre, a plugin that organizes coding work into stages such as defining scope, planning, executing, and cleaning up. It also describes the repository layout and release checks.

Use it when changing spectre prompts, subagents, hooks, skills, synchronization scripts, or tests.

It explains which files are the source of truth and helps agents follow the intended workflow without editing generated files by hand.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01581	$0.01581
Opus 5.5	$0.00632	$0.00632
Sonnet 5.5	$0.00316	$0.00316
Haiku 4.5	$0.00158	$0.00158

Security

Grade A, and why

spectre CLAUDE.md 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 1mo 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.

Project Overview

spectre is a Claude Code and Codex plugin providing standalone Scope, then Plan, Execute, and Ship, alongside ten retained public utilities. Scope owns feature boundaries; Plan owns implementation planning; Execute owns implementation, review, and proof; Ship owns cleanup, testing, rebase, and pull request closeout. It's a meta-prompt orchestration system where prompts invoke subagents.

Architecture

Meta-Prompt Orchestration

Skills are contract-form workflow prompts that:

Parse user arguments
Spawn parallel subagents (@spectre:dev, @spectre:analyst, etc.)
Subagents execute specialized prompts
Main prompt synthesizes findings and produces artifacts

Subagents

Agent	Purpose
`@spectre:dev`	Implementation with MVP focus
`@spectre:analyst`	Understand how code works
`@spectre:finder`	Find where code lives
`@spectre:patterns`	Find reusable patterns
`@spectre:web-research`	Web research
`@spectre:tester`	Test automation
`@spectre:reviewer`	Independent review

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.
