openconcho AGENTS.md

A set of project instructions for openconcho, a web and desktop interface for self-hosted Honcho instances. Honcho stores and displays information such as memories, peers, sessions, conclusions, and chats.

In plain words
What is it for?
Use it to bootstrap dependencies, start the web or desktop app, build it, run linting and type checks, execute tests, or run its Docker-based checks.
Why use it?
It gives an agent the repository's structure, preferred commands, and development conventions. This reduces uncertainty when building, testing, or running the project.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

openconcho 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.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

openconcho

Frontend UI for self-hosted Honcho instances — browse memories, peers, sessions, conclusions, and chat with memory context. Ships as a web app (@openconcho/web) and a Tauri desktop wrapper (@openconcho/desktop).

Commands

make is the canonical interface; it shells out to pnpm scripts which shell out to turborepo. CI calls the same targets — make help lists everything.

Command Purpose
make bootstrap Install deps + Playwright Chromium (run once after clone)
make dev-web Vite dev server on http://localhost:5173
make dev-desktop (or make dev) Tauri desktop app
make build Turbo: build web + desktop
make lint Biome check
make typecheck tsc --noEmit
make test Vitest (unit + integration), excludes e2e/
make test-e2e Playwright e2e (uncached)
make smoke-docker Local: build image + hermetic smoke test of the /api proxy (Docker required)
make up Run the web container from source (dev-forward, builds) at :8080
make prod Run the web container from the published image (pulls ghcr…:latest)
make down Stop + remove the web container (dev or prod)
make clean down + remove the locally built image
make check lint + typecheck + test
pnpm --filter @openconcho/desktop cargo-check Local Rust/Tauri compile check before pushing desktop changes
pnpm --filter @openconcho/web generate:api Regen src/api/schema.d.ts from openapi.json

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.
