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.
Add Block
Workflow
- Confirm the target project actually has a block registry/model system. If not, adapt the concept to the local architecture or stop.
- Identify the block category, ports, parameters, runtime semantics, serialization, codegen needs, and UI/editor representation.
- Implement in the established local patterns: registry, runtime/evaluator, rendering, inspector/editor UI, serialization, tests, and docs as applicable.
- For multiple blocks, build shared infrastructure first, then add blocks in small batches.
- Add focused unit tests plus integration/codegen tests if the project supports them.
- Create or update examples using
add-example semantics when useful.
- Manually verify the editor workflow if UI changed.
- Report files changed, tests, screenshots/manual checks, and any unsupported semantics.
For block-diagram repositories, load references/upstream-claude-adapted.md and complete the original 12-step checklist before landing. At minimum, cover registry/type definitions, runtime semantics, editor/rendering UI, inspector parameters, serialization/migration, codegen/export if present, examples, unit tests, integration tests, manual editor verification, documentation, and final self-audit.
Preserved Z Skills Invariants
- Require a concrete plan before broad block-system changes.
- Complete runtime, UI, serialization, tests, docs, and examples as applicable.
- Do not land with unresolved sign-off items.
