kodo: Instructions file for Codex

AGENTS.md

kodo AGENTS.md is an instructions file for Codex, OpenCode from ikamensh/kodo. It costs 1,641 tokens per session, scanned A, original, MIT.

Project instructions for kodo that define mocked end-to-end checks for its command-line workflows. They cover starting runs, resuming interrupted work, improvement mode, interactive input, logging, and the browser-based log viewer.

In plain words
What is it for?
Use them when testing kodo’s CLI, resume behavior, planning and improve modes, interactive flow, mocked orchestration, JSON logs, or the log viewer.
Why use it?
They provide repeatable checks without real API keys or external services, making it possible to verify that major workflows still connect and finish correctly.

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

kodo 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.

Rules for writing code in this repo

End-to-end test scenarios (mocked)

Primary user workflows and how to verify them with mocks (no API keys or real backends):

Scenario Script What it verifies
Non-interactive run scripts/smoke_test_cli.py CLI starts, mocked orchestrator runs one cycle, exits 0, JSON output
Full mocked run scripts/run_cli_mocked.py Goal + team + launch flow, run_start/cycle_end/run_end emitted
Resume interrupted run scripts/smoke_test_resume.py Creates incomplete run, kodo --resume finds it, passes correct ResumeState to orchestrator
Improve mode scripts/smoke_test_improve.py Project type detection (app vs library), 7-stage improve plan, orchestrator receives plan
Interactive flow scripts/smoke_test_interactive.py Goal input, team/orchestrator/model selection, refine skip, confirmation, launch
Improve full run scripts/run_improve_mocked.py kodo --improve on buggy_project, plan built, cycle completes

Log viewer (browser): python -m kodo.viewer <log.jsonl> or --serve --port 8080. scripts/verify_viewer_browser.py uses Playwright (optional dep) to verify embedded data, stats bar, timeline, expand button.

Report bug: kodo issue [RUN_ID] — resolves run like --resume (latest or by id), prompts for description (leave empty if crash obvious), packs run into run.tar.gz (log, config, goal, conversations), opens GitHub new-issue URL with run context pre-filled. User attaches the archive (GitHub rejects .jsonl). Tests: tests/cli/test_subcommands.py::TestCmdIssue.

Steering input (kodo/cli/_interactive.py): deliberately no persistent prompt line or status bar — any always-visible UI needs a renderer that redraws around every output write, which desyncs and corrupts scrollback under tmux (issue #52). Instead a cbreak watcher opens a plain input() composer on first keypress; orchestrator output is buffered while composing. Don't reintroduce prompt_toolkit/TUI rendering here.

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.
