pi-claude-bridge: Instructions file for Codex

AGENTS.md

pi-claude-bridge AGENTS.md is an instructions file for Codex, OpenCode from elidickinson/pi-claude-bridge. It costs 836 tokens per session, scanned A, original, MIT.

A project instruction file for the Claude Code bridge, describing agent rules, restricted actions, and how to verify claims about Claude Code’s behaviour.

In plain words
What is it for?
Use it when changing or investigating the bridge, especially when checking Claude Code’s file formats, requests, or undocumented behaviour.
Why use it?
It helps prevent unsupported conclusions and actions such as automatic commits or public GitHub activity. It also points contributors to tests and request captures when documentation or stored files are misleading.

Instructions file for CodexOpenCode

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

This is elidickinson/pi-claude-bridge's own configuration. It tells Codex and OpenCode how to work on pi-claude-bridge 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 pi-claude-bridge 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

pi-claude-bridge AGENTS.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.

Do not auto-commit.

Do not interact with the public without explicit permission. For example, do not open PRs or comment on github issues unless I say so.

Claims about how Claude Code behaves

~/.claude/projects/** is not evidence of what CC does. The bridge writes into the same files and CC re-serializes imported records under synthetic ids, so a scan of that directory largely reflects our own output handed back to us — 352 of 1,810 files hold both shapes. Before asserting "CC does X" from disk, split by provenance (CC-live records carry a real requestId/promptId; ours carry msg_syn_*/req_syn_*) and regroup by message.id, since CC stores one content block per record while cc-session-io stores one record per message. diag/audit-transcripts.mjs does both.

Better still, prove it with a live probe. tests/int-cc-contracts.mjs pins each undocumented behavior we depend on against the installed CC/SDK and is the right home for a new assumption; diag/capture-proxy.mjs captures the actual request bodies when the question is what CC sends. claude-code-rip/ lags the installed CLI by an unknown margin, so read it for mechanism, never for current behavior: what it gates, defaults, or omits may already have changed. And before reverse-engineering an SDK option at all, grep node_modules/@anthropic-ai/claude-agent-sdk/sdk.d.ts — it documents every settings field, several of which solve problems the CC source makes look intractable.

The same skepticism applies to any rate computed from the debug log. Before believing one, check the metric against a case whose answer you know: the cache-break scanner counted a request's uncached input as if the next request should read it back, which turned every tool-heavy turn into a false break and manufactured a dose-response that looked like a real finding.

Bin by era before comparing groups. A correlation computed over a window that straddles the onset of the phenomenon will credit whatever else changed. Three independent analyses agreed one account state was safe on 5,611 clean requests — every one of which predated the first failure; switching to that state reproduced the failure in five minutes.

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.
