odyssey: Instructions file for Codex

AGENTS.md

odyssey AGENTS.md is an instructions file for Codex, OpenCode from KhourySpecialProjects/odyssey. It costs 1,489 tokens per session, scanned A, original, MIT.

A workflow guide for a project that uses five coding agents: planner, implementer, reviewer, auditor, and wrap-up. It explains when to call each one, what it produces, and how work state moves between them.

In plain words
What is it for?
It is for coordinating agents during feature development, bug fixes, and refactoring, with plans, implementation updates, review findings, audit verdicts, and session notes.
Why use it?
It gives feature work a defined sequence from planning through review and final cleanup, including steps for handling problems.

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

odyssey 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 today.

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.

Odyssey — Agent Workflow

For project conventions, version constraints, and core patterns, see CLAUDE.md. For agent implementation details, see .claude/agents/*.md. This file documents the workflow — when to use which agent, how state flows between them, and what to do when things break.

The Five Agents

Agent When to invoke What it produces
planner Starting any feature, bug fix, or refactor docs/plans/ODY-342.md (spec + implementation tasks in one file)
implementer After plan is approved Code, tests, updated plan with completion status
reviewer After each implementation chunk Prioritized findings (critical/warning/suggestion)
auditor Feature branch complete, before merge docs/plans/<slug>-audit.md with verdict
wrap-up End of every working session Learnings, progress file, bloat pruning

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.
