Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is jsynowiec/mcp-server-airly's own configuration. It tells Codex and OpenCode how to work on mcp-server-airly 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-server-airly 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-server-airly 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 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.

Architecture Decisions

Documented in docs/adr/. When a significant architectural decision is made with the user during a session, add a new ADR and update the index. When a plan includes an ADR, it must be the first task executed so it guides the implementation.

@docs/adr/README.md

Conventions

  • Use Node subpath imports for module references: #/* for app modules (resolves to ./src/* under Bun, ./dist/* at runtime), #tests/* for test helpers. Never use relative imports.
  • SDK: @modelcontextprotocol/sdk v1 (deep imports: @modelcontextprotocol/sdk/server/mcp.js)
  • Schema validation: Zod v3, .describe() on every field
  • Tool names: snake_case
  • All logging to stderr (never stdout — that's the STDIO transport)
  • ESM only, .js extensions in imports

Testing

  • Mock globalThis.fetch in API client tests, InMemoryTransport.createLinkedPair() for tool/resource/prompt tests
  • No real API calls in tests
  • createServer() in src/server.ts wires everything without connecting a transport — tests import it directly, src/index.ts is a pure CLI runner

Completion Checks

When finishing work always verify that the package builds cleanly.

bun run build
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.
