What is KodoCode AGENTS.md?

A project instruction file for KodoCode, a web interface for using coding agents. It records the repository’s priorities, required checks, testing command, and maintainability rules.

Use it to guide work on KodoCode, including formatting, linting, type checking, testing, reliability, performance, and code organization.

It gives coding agents shared project context and completion rules, reducing inconsistent changes and missed validation steps.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00611	$0.00611
Opus 5.5	$0.00244	$0.00244
Sonnet 5.5	$0.00122	$0.00122

Security

Grade A, and why

KodoCode 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 2mo 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.

Task Completion Requirements

All of bun fmt, bun lint, and bun typecheck must pass before considering tasks completed.
NEVER run bun test. Always use bun run test (runs Vitest).

Project Snapshot

Kodo Code is a minimal web GUI for using coding agents like Codex and Claude.

This repository is a VERY EARLY WIP. Proposing sweeping changes that improve long-term maintainability is encouraged.

Core Priorities

Performance first.
Reliability first.
Keep behavior predictable under load and during failures (session restarts, reconnects, partial streams).

If a tradeoff is required, choose correctness and robustness over short-term convenience.

Maintainability

Long term maintainability is a core priority. If you add new functionality, first check if there is shared logic that can be extracted to a separate module. Duplicate logic across multiple files is a code smell and should be avoided. Don't be afraid to change existing code. Don't take shortcuts by just adding local logic to solve a problem.

Package Roles

apps/server: Node.js WebSocket server. Wraps Codex app-server (JSON-RPC over stdio), serves the React web app, and manages provider sessions.
apps/web: React/Vite UI. Owns session UX, conversation/event rendering, and client-side state. Connects to the server via WebSocket.
packages/contracts: Shared effect/Schema schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types. Keep this package schema-only — no runtime logic.
packages/shared: Shared runtime utilities consumed by both server and web. Uses explicit subpath exports (e.g. @t3tools/shared/git) — no barrel index.

Codex App Server (Important)

Kodo Code is currently Codex-first. The server starts codex app-server (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.

How we use it in this codebase:

Session startup/resume and turn lifecycle are brokered in apps/server/src/codexAppServerManager.ts.
Provider dispatch and thread event logging are coordinated in apps/server/src/providerManager.ts.
WebSocket server routes NativeApi methods in apps/server/src/wsServer.ts.
Web app consumes orchestration domain events via WebSocket push on channel orchestration.domainEvent (provider runtime activity is projected into orchestration events server-side).

Changes

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.
