About this skill
Prototype one risky assumption within a fixed budget, then keep or discard the result
What this skill tells your AI
The instructions your AI receives, as published by hashgraph-online/awesome-codex-plugins in plugins/nyldn/claude-octopus/skills/skill-prototype/SKILL.md and read by ahel’s review.
Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex. Cross-reference commands use installed skill names in Codex rather than
/octo:*slash commands. Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it. For host tool equivalents, seeskills/blocks/codex-host-adapter.md.
Bounded prototype
Use a prototype to answer one named question, not to start implementation by a different name.
Contract
Agree on the question, hypothesis, deadline, artifact path, and success signal
before writing. Record the source revision. Store artifacts through
scripts/plan-storage.sh, outside the installed plugin cache.
Native read-only plan mode permits a proposal only. Wait for an explicit execution handoff before creating files. Choosing prototype mode does not authorize deployment, provider calls, browser login, repository rewrites, or new permissions.
Stop at the deadline. Return observations, a keep, discard, or inconclusive
verdict, and the disposition of each artifact. Automatic cleanup may remove
only artifacts created by this run after ownership checks. Retain anything the
user changed.
The completion record contains question, hypothesis, deadline,
artifact_path, source_revision, observations, verdict, and
disposition.
