Codex Runtime Rules

These Z Skills are native Codex workflows derived from github.com/zeveck/zskills at commit 14dea81da487b2904ea7d69a27295f1869206cdf. They are invoked by natural language or by naming the skill; examples that look like slash commands are only shorthand for the skill name.

Use Codex behavior first:

• Read the current repository before acting. Prefer existing project scripts, config, and conventions over the upstream examples.
• Never use Claude-only tools or assumptions: no CronCreate, CronList, CronDelete, Agent/Task tool syntax, allowed-tools, .claude/settings.json, or automatic Claude hooks.
• Use sub-agents only when the user explicitly asks for agents, parallel work, or delegation. For Z Skills landing gates, prefer a fresh independent verification context when it is available without violating the current Codex delegation policy; otherwise run inline, disclose lower assurance, and do not auto-land unless the user accepts it.
• For isolation, create git worktrees explicitly with normal git worktree commands. Do not rely on an isolation: "worktree" parameter.
• Config lookup order is project .agents/zskills-config.json first, then project zskills-config.json, then legacy .codex/zskills-config.json, then legacy .claude/zskills-config.json only if already present. Do not create new .claude runtime config for Codex.
• Scheduling is not automatic in Codex. If the user asks for recurring runs, explain the schedule and ask before installing any local cron/system scheduler. For normal turns, perform the requested work now.
• Helper assets live at project .agents/zskills-support by default. Use project-local scripts/* first; fall back to $CODEX_HOME/zskills-support only for explicit global installs or legacy setups.
• Preserve Codex safety rules: do not revert unrelated work, stage files by name, avoid destructive git commands, and verify from actual diffs/tests.

Detailed upstream text is archived in references/upstream-claude-adapted.md for edge cases and future diffs. Load it only when the concise workflow below is insufficient.

Run Plan

Workflow

1. Parse the request: plan file, optional phase, status, finish, auto, pr, or direct.
2. Read the plan and current progress. For status, report phases, next work, blockers, and stop.
3. If the request is finish auto and it is not a runner-managed child prompt, start the external runner immediately when .agents/zskills-support/scripts/zskills-runner.sh or $CODEX_HOME/zskills-support/scripts/zskills-runner.sh exists. Run it as a shell command with the requested plan and --repo <repo-root>, relay the runner result, and do not manually execute a phase in the parent turn. This is the normal unattended entrypoint.
4. Treat prompts containing RUNNER-MANAGED CHUNK or External ZSkills runner contract for this chunk as child chunks launched by zskills-runner.sh; in that case do not start the runner again. Execute exactly one incomplete phase and follow the supplied runner contract.
5. Determine landing mode from explicit request, then config lookup order: .agents/zskills-config.json, zskills-config.json, legacy .codex/zskills-config.json, legacy .claude/zskills-config.json, fallback cherry-pick. Also read execution.base_branch, execution.remote, testing.*, ci.*, and dev_server.* before choosing commands.
6. Identify the next incomplete phase unless a phase was specified.
7. Validate scope: phase text, expected files, tests, and risks. If the phase is too broad, stop and recommend splitting or refine-plan.
8. Execution mode:
   • direct: work in the current tree only when not protected and explicitly requested.
   • default/cherry-pick: create a manual git worktree under /tmp/<project>-cp-<plan>-phase-<phase> on a named branch.
   • pr: create a branch/worktree suitable for a PR.
9. Implement the phase. If the user explicitly requested agents, delegate implementation to a worker with the worktree path; otherwise implement inline.
10. Verify from actual diffs with a fresh verification context before landing. Use a separate verifier only when that is available under the current Codex delegation policy; otherwise run inline verification, disclose the lower assurance, and do not auto-land unless the user explicitly accepts inline verification.
11. Update the plan progress tracker and write or update reports/plan-<slug>.md.
12. Land only after verification passes and the requested mode allows it. Stage explicit files, avoid unrelated changes, and preserve user work.
13. For finish without auto, preserve chunking: execute at most one substantive phase per top-level Codex turn unless the user explicitly says to continue in the same turn after seeing the phase result.

Chunked Finish

finish means "keep advancing this plan until done," not "merge all phases into one long context." After each phase:

1. Persist state in the plan progress tracker and reports/plan-<slug>.md.
2. Write a concise handoff: completed phase, branch/worktree, tests, landing state, next phase, blockers, and exact suggested next invocation.
3. Stop the turn unless the user explicitly requested same-turn continuation and the remaining context/risk is small, or this is finish auto in the parent turn and the external runner is available.
4. For finish auto, prefer resumable top-level turns over long in-context loops. Unattended completion is runner-backed by .agents/zskills-support/scripts/zskills-runner.sh or $CODEX_HOME/zskills-support/scripts/zskills-runner.sh; the skill must invoke that runner directly when available. The runner launches fresh codex exec invocations and validates durable state between chunks. Without that external runner, finish auto degrades to one chunk plus a handoff; Codex has no built-in Z Skills cron.
5. Never combine multiple plan phases into one implementation chunk just to reduce orchestration overhead.

Codex-Native Replacements

• Do not use CronCreate, CronList, or CronDelete. For every, next, or stop, explain that Codex has no built-in scheduler and ask before creating an external schedule.
• Do not use Claude Agent prompts or isolation parameters. Use Codex sub-agents only when explicitly authorized by the current Codex delegation policy.
• Treat upstream hook checks as manual guardrails. Codex does not run Z Skills hooks automatically.

External Runner Contract

An external runner may automate finish auto only by starting a new top-level codex exec process for each chunk. The runner must:

• acquire a per-plan lock before launching Codex;
• refuse unsafe git states such as merge, rebase, cherry-pick, conflicts, or unexpected dirty files;
• run with conservative child Codex flags and never default to dangerous bypass;
• derive progress from plan/report hashes and .zskills/tracking/ markers, not from chat text alone;
• run zskills-gate.sh and post-run invariants before scheduling the next chunk;
• stop on no progress, missing reports/markers, direct-mode ambiguity, PR/CI waiting states, timeouts, or max chunk limits.

If no runner is active, report the exact next invocation instead of trying to continue multiple phases in one context.

Landing Modes

Use one shared config contract across Z Skills. Read .agents/zskills-config.json, then zskills-config.json, then legacy .codex/zskills-config.json, then legacy .claude/zskills-config.json.

• execution.landing: "direct": work on the current branch/main only with a clean tree, no unrelated changes, explicit current-turn authorization for broad/autonomous work, and execution.main_protected false or explicitly overridden after warning.
• execution.landing: "cherry-pick": work in a manual git worktree, commit the phase there, verify, then cherry-pick the scoped commit back to ${execution.base_branch:-main} from ${execution.remote:-origin}. This is the default.
• execution.landing: "pr": work in a manual git worktree on ${execution.branch_prefix}..., push to ${execution.remote:-origin}, create a PR with gh if available, and do not push directly to main.

Explicit request words direct or pr override config for the current invocation. locked-main-pr means execution.landing: "pr" plus execution.main_protected: true.

Landing Helper Contract

Use project-local helpers first. If absent, inspect .agents/zskills-support/scripts/* or $CODEX_HOME/zskills-support/scripts/* before relying on prose:

• worktree-add-safe.sh: create isolated worktrees and reject branch/path poisoning.
• write-landed.sh and land-phase.sh: record scoped landing state and cleanup only expected ephemeral files.
• post-run-invariants.sh: check base freshness, landing evidence, report state, and dirty tree after landing.
• zskills-gate.sh: Codex-native pre-land/pre-continue/pre-push gate for reports, tracking markers, ignored tracking files, and untracked artifacts.

Do not run support scripts blindly when a project has different branch names or report paths; pass config-derived base/remote values or adapt a project-local copy.

Minimum Report

Every executed phase should report: plan, phase, branch/worktree, files changed, tests run, verification result, landing result, and remaining phases. Do not claim that work was committed, cherry-picked, pushed, or fully landed until that git operation has actually succeeded. Before landing, use pending language; after landing, update the report with the real landed state. Verification reports used as landing evidence are project artifacts; keep them under reports/ and land them with the phase report unless the repository has an explicit external-report convention.

Tracking And Gates

Retain file-based tracking even though Codex does not run Claude hooks:

1. Create .zskills/tracking/<pipeline-id>/ for the plan run.
2. Before verification, write requires.verify-changes.<tracking-id> with phase, diff base, and expected report path.
3. During the phase, write canonical markers: step.run-plan.<tracking-id>.implement, step.run-plan.<tracking-id>.verify, and step.run-plan.<tracking-id>.report.
4. For finish, if another phase remains, write handoff.run-plan.<tracking-id> after the phase so the next top-level turn can resume without relying on conversation memory. Do not leave step.run-plan.<tracking-id>.land or fulfilled.run-plan.<tracking-id> present for a non-final chunk.
5. Only when the plan is complete, write step.run-plan.<tracking-id>.land and finally fulfilled.run-plan.<tracking-id>, and remove any stale handoff.run-plan.<tracking-id>.
6. Before landing, check the implement, verify, and report markers plus the persistent verification report. Treat missing or inconsistent markers as a stop condition unless the user explicitly chooses manual recovery.

Tracking files are ephemeral gates. Do not include .zskills/, .zskills-tracked, or other tracking marker files in landed commits or PRs unless the user explicitly asks to version them.

Post-Landing Gates

• Before landing, pushing, scheduling another chunk, or declaring completion, re-check whether main/base moved since verification. If it moved, re-run verification on the current diff.
• After landing, run project-local scripts/post-run-invariants.sh when available. If absent, inspect or adapt .agents/zskills-support/scripts/post-run-invariants.sh or $CODEX_HOME/zskills-support/scripts/post-run-invariants.sh when the project uses Z Skills tracking. Do not schedule the next chunk or declare completion if invariants fail.
• Before declaring a phase complete, inspect git status --short. Only expected ephemeral tracking files may remain uncommitted. Untracked reports, source files, tests, plans, or config files are a stop condition.

Preserved Z Skills Invariants

• Extract and follow the phase text exactly, but challenge unsafe or impossible instructions.
• Write/update the phase report before landing.
• Require a separate verifier per phase when it is available under the current Codex delegation policy; otherwise disclose inline verification and reduced assurance.
• Block auto-landing when verification fails, user sign-off is required, scope changed materially, or unrelated changes are present.
• Preserve delegate/direct/worktree/PR modes with Codex-native mechanics.
• Preserve chunking to reduce context fatigue and resource anxiety; do not collapse remaining phases into one mega-phase.
• Preserve tracking-file gates as manual Codex checks, even without hook enforcement.
• Keep tracking files out of landed commits and PRs by default.
• Re-run verification when the base moved and run post-run invariants before continuing.
• Do not leave verification reports or other project artifacts untracked after landing.
