skill-based-architecture: Instructions file for Claude Code

CLAUDE.md

skill-based-architecture CLAUDE.md is an instructions file for Claude Code from WoJiSama/skill-based-architecture. It costs 813 tokens per session, scanned A, a copy of skill-based-architecture AGENTS.md, MIT.

Instructions for a meta-skill repository that routes coding tasks through focused, reusable workflows instead of scattered project rules.

In plain words
What is it for?
Maintaining the skill-based architecture, routing configuration, repository self-documentation, automatic triggers, and rules for handling changes that affect users or external interfaces.
Why use it?
They require agents to read the router and select the matching workflow, helping them use only the guidance relevant to the current task.

Instructions file for Claude Code

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

This is WoJiSama/skill-based-architecture's own configuration. It tells Claude Code how to work on skill-based-architecture 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 skill-based-architecture 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

skill-based-architecture 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 7d 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.

Origin

This is a copy

91% identical to skill-based-architecture AGENTS.md — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This repo is the skill-based-architecture meta-skill itself. Formal docs live at the repo root (self-hosting layout, see references/layout.md). Read SKILL.md first — it is the router.

Quick Routing (survives context truncation)

Task routes live in references/self-hosting-routing.yaml.

For every new task:

  1. Read SKILL.md.
  2. Read references/self-hosting-routing.yaml.
  3. Match exactly one route by labels, trigger_examples, and task intent; if none matches, use other.
  4. Follow only that route's workflow; the route does not preload project knowledge.
  5. Let the workflow inspect the smallest evidence that can decide the next action, then pull later knowledge only when that unresolved decision requires it.

Auto-Triggers

  • New task in same session → always re-match the route above. After a route change, read the new workflow; after compaction, recover only the current workflow and decision-relevant evidence. Only one clear read-only or fixed-contract maintenance action/check with no new desired behavior executes directly. A request that adds or changes user-visible behavior, a business flow/state, or an external contract first reaches requirement-ready; if meaning is incomplete, return current understanding, real risk/conflict, and the minimum normative question without an implementation Plan. Then establish a Task Anchor, prove the current owner and Current -> Target until implementation-ready, and only afterward derive a concise harness-native Plan before mutation. Present only useful alignment, do not repeat visible steps in chat, and run the compact Anchor Checkpoint before each main step. This is Session recitation, not planning-file persistence. Can't tell if context compacted? Re-read the current workflow.
  • Before any requested commit/push/MR/deploy/publish delivery, enter templates/skill/workflows/task-closure.md; Ready for Delivery is not completion, and Closure remains open until the requested artifact is verified.
  • Closure checks fire by blast-radius bucket (path-based classification of files changed):
    • A (entry shells / SKILL.md / routing yaml / scripts / *.tpl) → full AAR + smoke-test + path-integrity gates
    • B (template rules/workflows non-example, references linked from SKILL.md, workflows/full-migration.md) → lightweight AAR only
    • C (README, examples, docs, UPSTREAM-CHANGES, references not linked from SKILL.md) → skip closure entirely
    • Multiple files in one task → take the max bucket. Path not in any list → default B. Trivial edit (typo / whitespace) in an A-bucket file still = full closure (bucket measures what could break, not what changed).
    • Pure Q&A / code explanation / read-only investigation / advice with no file changes → exempt; no AAR, no smoke-test.
    • Full path lists + canonical bucket rules: references/protocols.md § Task Closure Protocol.
  • When adding to templates/ → apply the "would two real projects disagree?" admission test (templates/ANTI-TEMPLATES.md)

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.
