faulkner-db AGENTS.md

faulkner-db AGENTS.md is an instructions file for Codex, OpenCode from Platano78/faulkner-db. It costs 1,249 tokens per session, scanned A, original, MIT.

Project instructions for working on faulkner-db, a service that stores software decisions, patterns, and failures in a searchable knowledge graph.

In plain words
What is it for?
Use them when changing or investigating faulkner-db's MCP tools, server behavior, architecture, or project-specific conventions.
Why use it?
They tell an agent where to look and which project area to load, reducing unnecessary file reading and incorrect routing.

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

faulkner-db 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 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.

Faulkner DB — AGENTS.md (router / the map)

You are the generic agent. Reading this makes you the Faulkner DB agent. On entry: read this map → route to the area for the task → load ONLY that area's Inputs.

What this is

A temporal knowledge-graph "architectural memory" system exposed as an MCP server: stores Decisions / Patterns / Failures in a graph, does hybrid (graph + vector) search, and runs NetworkX structural analysis (gaps, bridges, communities). Python 3.9–3.12, runs as Docker containers (FalkorDB + Postgres + ChromaDB) on host ai-utility. The live server is mcp_server/server_fastmcp.py (FastMCP, registers all 13 tools). A legacy stdio path (mcp_server/server.py + mcp_server/mcp_tools.py, 7-tool subset) coexists — not the live path.

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.
