About the project

Kaneo is an open-source project-management application for organizing work with kanban boards, issues, and issue tracking. Teams use it to manage projects, and its self-hosted design lets them keep the application and data under their control. The catalogue contains skills, rules, instructions, and an MCP integration for working with Kaneo.

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

kaneo 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.

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kaneo

Kaneo is a fast, simple, self-hosted project manager. The Hono API owns domain behavior and authorization; the React app uses its typed client. PostgreSQL stores durable state, events and WebSockets keep clients current, and Redis is optional for delivery across API instances.

People use Kaneo to manage active work on instances they control. Changes reach existing tasks, workspaces, and deployments, not just a fresh dev setup. Protect what they rely on: quick boards, straightforward workflows, reliable live updates, and self-hosting that stays simple. A change that weakens those needs a compelling product reason.

Treat this guide as a set of defaults. The developer's request takes precedence.

What matters

  • Keep routine work simple. Solve the user's problem with the smallest model that makes the behavior clear. Read the relevant code first, but do not keep complexity just because it is already there.
  • Keep modules small. Across the whole repo, give each file one responsibility: one component per file, and pure helpers and types in their own modules next to the code that uses them, with tests beside them. When a file grows a second concern, split it into a folder. Do not extract one-line wrappers; inline those.
  • Keep boards fast. Task-heavy views and realtime updates should not move or render more data than they need.
  • Keep self-hosting easy. A single instance must work without Redis or another managed service. Support both bundled same-origin and separately hosted API and web deployments.
  • Respect workspace boundaries. The API enforces authentication and permissions; a hidden UI control is not an authorization check. Never leak secrets or private workspace data through responses, logs, events, WebSockets, or MCP.

Where code lives

  • apps/api — Hono routes, controllers, database, events, integrations, and WebSockets.
  • apps/web — React UI, fetchers, TanStack Query hooks, and realtime cache updates.
  • apps/mobile — Expo/React Native app for Android and iOS with its own HTTP client; see apps/mobile/AGENTS.md.
  • packages/libs — typed Hono client and URL helpers; packages/permissions — permission vocabulary and built-in roles.
  • packages/mcp — published stdio MCP package.
  • apps/docs — product and API docs; apps/site — public site and docs host.
  • charts/kaneo — Helm chart; tests/api and tests/api-integration — API tests.

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.
