+## Named agent dispatch
+
+Claude Code skills reference named agent types like `superpowers:code-reviewer`.
+Codex does not have a named agent registry — `spawn_agent` creates generic agents
+from built-in roles (`default`, `explorer`, `worker`).
+
+When a skill says to dispatch a named agent type:
+
+1. Find the agent's prompt file (e.g., `agents/code-reviewer.md` or the skill's
+   local prompt template like `code-quality-reviewer-prompt.md`)
+2. Read the prompt content
+3. Fill any template placeholders (`{BASE_SHA}`, `{WHAT_WAS_IMPLEMENTED}`, etc.)
+4. Spawn a `worker` agent with the filled content as the `message`
+
+| Skill instruction | Codex equivalent |
+|-------------------|------------------|
+| `Task tool (superpowers:code-reviewer)` | `spawn_agent(agent_type="worker", message=...)` with `code-reviewer.md` content |
+| `Task tool (general-purpose)` with inline prompt | `spawn_agent(message=...)` with the same prompt |
+
+### Message framing
+
+The `message` parameter is user-level input, not a system prompt. Structure it
+for maximum instruction adherence:
+
+```
+Your task is to perform the following. Follow the instructions below exactly.
+
+<agent-instructions>
+[filled prompt content from the agent's .md file]
+</agent-instructions>
+
+Execute this now. Output ONLY the structured response following the format
+specified in the instructions above.
+```
+
+- Use task-delegation framing ("Your task is...") rather than persona framing ("You are...")
+- Wrap instructions in XML tags — the model treats tagged blocks as authoritative
+- End with an explicit execution directive to prevent summarization of the instructions
+
+### When this workaround can be removed
+
+This approach compensates for Codex's plugin system not yet supporting an `agents`
+field in `plugin.json`. When `RawPluginManifest` gains an `agents` field, the
+plugin can symlink to `agents/` (mirroring the existing `skills/` symlink) and
+skills can dispatch named agent types directly.
+
+## Environment Detection
+
+Skills that create worktrees or finish branches should detect their
+environment with read-only git commands before proceeding:
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
+```
+
+- `GIT_DIR != GIT_COMMON` → already in a linked worktree (skip creation)
+- `BRANCH` empty → detached HEAD (cannot branch/push/PR from sandbox)
+
+See `using-git-worktrees` Step 0 and `finishing-a-development-branch`
+Step 1 for how each skill uses these signals.
+
+## Codex App Finishing
+
+When the sandbox blocks branch/push operations (detached HEAD in an
+externally managed worktree), the agent commits all work and informs
+the user to use the App's native controls:
+
+- **"Create branch"** — names the branch, then commit/push/PR via App UI
+- **"Hand off to local"** — transfers work to the user's local checkout
+
+The agent can still run tests, stage files, and output suggested branch
+names, commit messages, and PR descriptions for the user to copy.
