open-bridge CLAUDE.md

open-bridge CLAUDE.md is an instructions file for coding agents from bks-lab/open-bridge. It costs 551 tokens per session, scanned A, original, MIT.

Project instructions for Open Bridge, a setup that stores information about your repositories, clients, and working methods in plain Markdown and YAML files. An AI coding agent reads this context at the start of a session, regardless of which model or coding interface is used.

In plain words
What is it for?
Use it to guide session startup, task management, agent use, standing instructions, commands, and project lookup. It is also the Claude Code-specific supplement to the repository's main AGENTS.md manual.
Why use it?
It prevents the agent from starting each session without knowing the project background and working rules. A project registry is indexed so the agent can load details about a named repository or client without keeping every project in context all the time.

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

open-bridge 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 5d 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 specifics

The canonical, tool-agnostic operating manual for this repo is the ~800-line AGENTS.md (Linux-Foundation convention, read natively by Codex/Cursor/Copilot/Gemini). It is inlined above via @AGENTS.md, so the full manual — session-start gate, rules, task management, agents, standing orders, commands — is already in your context. This file only adds the Claude-Code-specific bits.

The project registry (ecosystem.yaml, created at onboarding, gitignored) is no longer @-imported. It is indexed: Phase 1 runs python3 scripts/context-index.py ecosystem.yaml, which emits the settings verbatim and one line per repo, customer and workspace; the entry itself arrives with --get <name> when somebody names one. The registry is the always-on file that grows with the instance rather than with this repo, and reading it whole meant carrying a paragraph about every project in order to know that the project exists. Details: docs/context-index.md.

That trade has a real cost worth naming: an @-import is resident for the whole session, while a Phase 1 read is ordinary conversation and can be compacted away later. The card is small enough to re-run, and --get is always available; a file large enough to matter here is too large to keep resident on that argument alone.

Onboarding appends further @-imports here as it seeds the live USER files (e.g. identity/agent/SOUL.md + IDENTITY.md).

Run the Phase-0 session-start gate before responding. Belt-and-suspenders, so the gate survives even if the import above fails to resolve: Do not answer the first user message (even "hi", "status", "what can you do") before running Phase 0. Phase 0 mechanic, inlined here so it works even if @AGENTS.md is silently dropped: detect the current branch + whether a user/* branch exists + whether bridge-config.yaml is present, and route accordingly — on the core branch with no user/* and no bridge-config.yaml, trigger the NEW USER path (/bridge-onboard); otherwise route to the matching state (wrong-branch, orphan, broken-config, or normal task-management load).

If @AGENTS.md does not resolve in your harness, read AGENTS.md manually before responding.

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.
