Hyperflow Doctrine (single-agent port)

Apply Hyperflow's behavioral floor in surfaces that load skills but do not provide the full Claude Code multi-agent runtime.

Runtime Adaptation

Codex and Antigravity run one foreground agent. Where the full doctrine says to dispatch parallel workers under reviewers:

• Do the work yourself, one coherent batch at a time.
• Self-review each batch before moving on.
• Run a final integration self-review over the cumulative diff.
• Preserve the same autonomy, clarification, commit cadence, file-first artefact, no-attribution, and security rules.

Codex Function Router

Codex loads Hyperflow as skills, not as native Claude-style slash commands. Treat these user messages as function aliases and execute the matching skill workflow inline in the current thread:

Do not answer that /hyperflow:* is an unknown command in Codex. Strip the alias, load the matching skills//SKILL.md, and follow its workflow. If that workflow says to use unavailable Claude Code tools (Agent, Skill, or AskUserQuestion), emulate them: do worker/reviewer steps inline with visible labels, continue chained skills inline, and use the Codex question fallback below.

Codex Subagents And Auto-Chain

When Codex exposes multi-agent tools, map Hyperflow agent dispatches to Codex subagents instead of falling back to inline work:

• Hyperflow Agent worker/searcher/writer calls map to Codex worker or explorer subagents.
• If the callable tool is named multiagentv1.spawnagent, use agenttype: worker for implementer/writer execution and agent_type: explorer for search/codebase-research tasks, then collect results before review.
• Spawn independent sibling workers together when the runtime supports parallel subagent calls.
• Worker roles use gpt-5.4 with low reasoning in fast mode when model overrides are available and Hyperflow Codex defaults are active.
• Thinking roles stay in the foreground on gpt-5.5 with task-adaptive reasoning: low for trivial docs/config checks, medium for normal planning/review, and high for debugging, architecture, security, or final integration review.
• Never request or default to xhigh.

When Codex does not expose subagent tools in the current session, use the single-agent port above: execute worker/reviewer phases inline with clear labels and continue.

For /hyperflow:workflow, use the Codex portable workflow adapter instead of falling back to scope: research and planning, .hyperflow/tasks/ progress tracking when needed, parallel subagents when exposed, inline worker/reviewer phases otherwise, adversarial verification, quality gates, per-task conventional commits, and final synthesis. Do not describe this as native Claude Code dynamic workflow support.

Codex also may not expose Claude Code's Skill handoff tool. Treat every Hyperflow handoff as an inline auto-chain:

• amplify handoff continues into spec after the required handoff gate.
• spec continues into scope after the approved spec.
• scope continues into dispatch after writing the task file.
• dispatch offers audit and deploy structural gates, then runs the selected follow-up inline.
• audit fix gates continue into scope with the generated audit-fix spec.

Do not stop with "Skill tool unavailable" in Codex. Auto-chain is a behavior contract, not a host API requirement.

Codex Interaction Fallback

Codex may load Hyperflow skills without exposing the full AskUserQuestion popup UI. In that case, do not skip the question or silently choose the recommended option. Render the same structural gate as a concise chat block and wait for the user's answer:

Hyperflow Question
<question>

1. <recommended option> (Recommended) — <short consequence>
2. <option> — <short consequence>

Use this fallback for every required clarification or structural gate: Amplify handoff, Spec chain mode, Spec brainstorming questions, Scope ambiguity questions, Dispatch audit/deploy gates, Audit fix gate, Deploy commit-inclusion and push gates, and any security/irreversibility escalation. It is still banned to ask invented confirmation questions such as "should I proceed?".

Codex Model Policy

• Thinking roles use gpt-5.5.
• Worker roles use gpt-5.4 in fast mode.
• Resolve thinking reasoning by task/profile: low for trivial docs/config checks, medium for normal planning/review, and high for debugging, architecture, security, and final integration.
• Never default Codex reasoning to xhigh.

Core Rules

1. Execute task-shaped requests without confirmation.
2. Clarify only after reading the relevant code and only for genuine ambiguity.
3. Keep long-form plans, specs, task decompositions, and audits under .hyperflow/.
4. Use conventional commits, one distinct user task per commit.
5. Never reference the model as the actor in commits, docs, comments, task files, or memory.
6. Respect the security blocklist in security.md.
