gencc-link: Instructions file for Codex

AGENTS.md

gencc-link AGENTS.md is an instructions file for Codex, OpenCode from berntpopp/gencc-link. It costs 1,120 tokens per session, scanned A, original, MIT.

A repository instruction file for GenCC-Link, a Python server that answers gene–disease validity questions using Gene Curation Coalition data stored locally.

In plain words
What is it for?
Use it when working on the server, its data ingestion, SQLite search database, MCP interface, Docker setup, documentation, or tests.
Why use it?
It gives coding agents the project background, source-of-truth guidance, working rules, and commands needed to make consistent changes.

Instructions file for CodexOpenCode

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

This is berntpopp/gencc-link's own configuration. It tells Codex and OpenCode how to work on gencc-link 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 gencc-link 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

gencc-link 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 6d 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.

Shared repository instructions for agentic coding tools working in GenCC-Link.

Project

GenCC-Link is a Python FastAPI + MCP server that grounds gene-disease validity questions in the Gene Curation Coalition (GenCC) dataset. GenCC harmonizes curated gene-disease assertions (Definitive ... Refuted) from member organizations (ClinGen, Genomics England PanelApp, Orphanet, Ambry, Invitae, Illumina, and others). GenCC has no live API yet, so the server downloads the bulk submissions export and serves it from a local SQLite + FTS5 database; the analytical value-add is per-pair consensus and conflict detection across submitters.

Primary areas:

  • gencc_link/ - Python package: config, models, data store, services, MCP code
    • ingest/ - download + parse + build the SQLite database
    • data/ - schema.sql, read-only repository, repository Protocol (base.py)
    • services/ - consensus aggregation, response shaping, orchestration
    • mcp/ - facade, tools, capabilities, envelope, next_commands, resources
  • tests/ - unit and integration tests; fixtures under tests/fixtures/
  • docker/ - Dockerfile and Compose deployment files
  • docs/ - architecture, usage, and design specs (docs/superpowers/)
  • .claude/skills/ - repo-local Claude Code workflows for recurring tasks

Source Of Truth

  • Use this file for shared repo-wide agent guidance.
  • Keep CLAUDE.md lean and Claude-specific; it should reference this file.
  • Prefer Makefile targets over ad hoc commands.
  • Use uv.lock as the dependency lock source of truth.
  • The GenCC export schema and classification ranks live in gencc_link/constants.py; the SQLite schema in gencc_link/data/schema.sql.

Working Rules

  • Do not revert or overwrite changes you did not make unless explicitly asked.
  • Keep edits scoped to the task and avoid unrelated refactors.
  • Prefer existing code patterns over new abstractions.
  • Put tests under tests/; do not create alternate test roots.
  • Use ASCII unless a file already requires non-ASCII content.
  • Keep public hosted MCP tools read-only and research-use scoped.
  • Respect the GenCC download quota (20/IP/day): use HEAD + conditional requests (ETag / Last-Modified); never poll the full export in a loop.

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.
