kobato AGENTS.md

kobato AGENTS.md is an instructions file for Codex, OpenCode from syhily/kobato. It costs 7,213 tokens per session, scanned A, original, MIT.

Project-specific instructions for working on syhily/kobato, a React application with server rendering, SQLite storage, and a DuckDB analytics sidecar. They describe its code layout, configuration file, and environment-variable rules.

In plain words
What is it for?
Use them when navigating the repository, changing server or client code, working with configuration, or running tests and tools that need a specific config file.
Why use it?
They help an agent make changes that fit the project’s existing structure and configuration behavior.

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

kobato 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.

Project conventions

Repository conventions for AI agents and contributors.

Quick orientation

  • React Router 8 Framework Mode with SSR (appDirectory: 'src'), React 19 TSX/TS only, SQLite (node:sqlite) + a DuckDB analytics sidecar.
  • Path alias @/*./src/*.
  • Five layers under src/: routes/ (orchestration), server/ (SSR), client/ (browser), ui/ (components), shared/ (isomorphic).

Config file

Infrastructure configuration lives in kobato.config.json — auto-created with defaults when missing. src/server/infra/config.ts's CONFIG_TABLE maps nested config paths to Zod schemas; the validated serverConfig object exported from that module is what consumers read. Env var names are derived by convention (path.join('__')storage__database).

  • Location order: --config <path> → SEA <execDir>/kobato.config.json./kobato.config.json~/.config/kobato.config.json. First existing wins.
  • Precedence: schema defaults < config file < env vars. Env values differing from the file are written back.
  • VITEST=true without --config → env-only, zero filesystem access.
  • Tooling that spawns the binary MUST pass --config <tempDir>/… to avoid persisting throwaway config next to the binary.
  • Adding a config value: add a CONFIG_TABLE row → update kobato.config.example.json → cover it in tests/unit/server/infra/config.test.ts.

Subdirectory conventions

Claude loads these additively as it moves through the codebase:

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.
