sigrank-mcp: Instructions file for Codex

AGENTS.md

sigrank-mcp AGENTS.md is an instructions file for Codex, OpenCode from SunrisesIllNeverSee/sigrank-mcp. It costs 1,797 tokens per session, scanned A, original, MIT.

Project instructions for SigRank MCP, a command-line tool and MCP server for working with signature rankings. They document tests, local commands, alternative Bun commands, and the automatic publishing process.

In plain words
What is it for?
Installing dependencies, running tests and the local command-line tool, using Bun as an alternative runtime, and understanding the automated npm release workflow.
Why use it?
They provide the repository’s exact development and release rules, including how publishing is triggered and which manual actions are forbidden. This reduces errors when testing or releasing changes.

Instructions file for CodexOpenCode

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

This is SunrisesIllNeverSee/sigrank-mcp's own configuration. It tells Codex and OpenCode how to work on sigrank-mcp 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 sigrank-mcp 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

sigrank-mcp 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 yesterday.

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.

SigRank MCP — Agent Rules

Quick reference

What Command
Unit tests node test.mjs (313 assertions)
Signing tests node sign.test.mjs
Run CLI locally node index.mjs (TUI if TTY, MCP server if piped)
Install deps npm install

Bun (faster alternative): All commands work with Bun (~10-30x faster):

What Bun command
Install deps bun install
Unit tests bun test.mjs
Signing tests bun sign.test.mjs
Run CLI locally bun index.mjs
Run published CLI bunx sigrank (same as npx sigrank but faster)

Bun is installed at ~/.bun/bin/bun (v1.3.13). It reads the same package.json and package-lock.json — no migration needed. Use bunx instead of npx for one-off package execution.

Publishing

Auto-publish is ON (2026-07-31). Push to main triggers .github/workflows/publish.yml, which runs tests, bumps the patch version, publishes to npm, pushes the version commit back to main, and dispatches a sync-mcp-version event to sigrank-app (so the app's MCP_VERSION constant auto-updates → Vercel auto-deploys).

Do NOT manually run npm publish or npm version. The workflow handles it. If you need to publish manually (e.g. the workflow is broken), bump the patch version in package.json, commit, push, and the workflow will handle the rest.

Do NOT add npm publish or npm version to commit messages or scripts. The workflow does this automatically. Manual publishes create duplicate versions.

Version scheme: 1.0.x (graduated from 0.0.x on 2026-08-27). The patch (third decimal) increments on every release: 1.0.01.0.11.0.2 → ... Never use minor bumps (1.1.x, 1.2.x) or major jumps (2.0.x). The 0.0.x format was retired because legacy 0.17.x/0.18.x/0.19.x versions sorted higher in semver (0.17.2 > 0.0.232), causing the MCP Registry to show a stale version as "latest." Graduating to 1.0.x fixes this (1.0.0 > 0.19.0 > 0.17.2).

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.
