mcp-sso: Instructions file for Claude Code

CLAUDE.md

mcp-sso CLAUDE.md is an instructions file for Claude Code from acartag7/mcp-sso. It costs 420 tokens per session, scanned A, original, MIT.

Repository instructions for the mcp-sso project, including its rules for code quality, testing, security, and Claude Code session notes.

In plain words
What is it for?
Use them when changing the repository, especially around its acceptance tests, build phases, trust boundaries, allowlists, and existing verification commands.
Why use it?
They give an AI coding assistant the project’s standing rules and checks to follow, reducing the risk of breaking required tests or security safeguards.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is acartag7/mcp-sso's own configuration. It tells Claude Code how to work on mcp-sso 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 mcp-sso 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

mcp-sso 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 9d 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.

What it actually says

@AGENTS.md

Claude Code session notes (mcp-sso)

AGENTS.md is the canonical source for this repo's rules, structure, commands, invariants, and always-check list. This file keeps only context that is specific to Claude Code sessions here and does not belong in the portable AGENTS.md.

Build/extraction context (lives in Claude memory, not in the repo)

  • The build/extraction plan is not kept in this repo (no handoff artifacts in repos — repo docs are durable-only). It lives in this project's Claude memory and in session prompts from the owner.
  • Extraction source is ~/project/smart-fetch (Captatum) — read-only reference. Never copy deployment-specific details (hostnames, infra) or any security-audit* document into this repo.

Repository quality rules

The canonical rules live in AGENTS.md, which this file includes via @AGENTS.md. In short: keep the 16 manifest-frozen acceptance tests and all five active phases intact; keep freeze-hash, mixed-diff, and stage-artifact active; define product and security contracts before new trust boundaries; fail closed with allowlists; and run the existing repository gates.

Sweep all adapters, stores, examples, and mutable-state exit paths for sibling defects. Never weaken checks or push directly to protected branches. Use conventional commits with the required Spec: <path> trailer, and prove each regression test fails without its fix. Codex Reviewer must review the exact final PR head, and every review object and inline thread must be read before merge. After more than two unsuccessful review cycles, split or redesign the PR.

Local review before Codex is class-closure-review, not a prose “sibling sweep.” Empty matrix cell = do not push.

Changes

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.
