specweave: Instructions file for Claude Code

CLAUDE.md

specweave CLAUDE.md is an instructions file for Claude Code from anton-abyzov/specweave. It costs 2,475 tokens per session, scanned A, original, MIT.

Repository instructions for SpecWeave, a tool that turns product ideas into planned software work. They cover code navigation, automatic workflow selection, and when to make a plan before coding.

In plain words
What is it for?
Use them to start SpecWeave work, inspect code definitions and references, route product descriptions into feature planning, and coordinate multi-step tasks with subagents.
Why use it?
They give the coding agent a consistent process for handling larger tasks and reduce unclear requirements or premature implementation.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions subagents; mentions Claude Code.

This is anton-abyzov/specweave's own configuration. It tells Claude Code how to work on specweave 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 specweave configures →

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

specweave 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Framework: SpecWeave | Truth: spec.md + tasks.md

LSP (Code Intelligence)

Native LSP broken in v2.1.0+. Use: specweave lsp refs|def|hover src/file.ts SymbolName

Getting Started

Your first increment starts at 0001. Just describe what you want to build:

/sw:increment "your-feature"

Auto-Detection

SpecWeave auto-detects product descriptions and routes to /sw:increment:

Signals (5+ = auto-route): Project name | Features list (3+) | Tech stack | Timeline/MVP | Problem statement | Business model

Opt-out phrases: "Just brainstorm first" | "Don't plan yet" | "Quick discussion" | "Let's explore ideas"

Workflow Orchestration

1. Plan Mode Default (MANDATORY)

  • ALWAYS enter plan mode for ANY non-trivial task (3+ steps or architectural decisions)
  • Call EnterPlanMode BEFORE writing specs, plans, or task breakdowns
  • Do NOT start implementation until the plan is reviewed and approved
  • If something goes sideways, STOP and re-plan -- do not keep pushing
  • Write detailed specs upfront to reduce ambiguity
  • /sw:increment REQUIRES plan mode -- never skip it

2. Subagent Strategy

  • Use subagents liberally to keep main context clean
  • Offload research, exploration, and parallel analysis to subagents
  • One task per subagent for focused execution
  • Append "use subagents" to requests for safe parallelization
  • In team mode, sub-agents submit plans for team lead review before implementing

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.
