# Port Codex artifacts to Claude

Finds Codex skills/agents that have no Claude counterpart in this repo and adapts them
to Claude Code conventions, one item at a time with per-item approval.

## Procedure

### 1. Compute the gap

Run both diffs in parallel:

```bash
# Skills missing from claude/
comm -23 \
  <(ls global/codex/skills/ | sort) \
  <(ls global/claude/skills/ | sort)

# Agents missing from claude/ (strip .toml extension for comparison)
comm -23 \
  <(ls global/codex/agents/ | sed 's/\.toml$//' | sort) \
  <(ls global/claude/agents/ | sed 's/\.md$//' | sort)
```

If both lists are empty, report "No gaps found — codex/ and claude/ are in sync" and stop.

### 2. Present the gap list

Show the user two sections:

```text
Skills to port   (global/codex/skills/<name>/SKILL.md → global/claude/skills/<name>/SKILL.md)
  - <name>
  ...

Agents to port   (global/codex/agents/<name>.toml → global/claude/agents/<name>.md)
  - <name>
  ...
```

Ask which items to port. Do not proceed without explicit approval per item.

### 3. Adapt skills (for each approved skill)

Read `global/codex/skills/<name>/SKILL.md`, then apply these substitutions:

| Find | Replace with |
|---|---|
| `AGENTS.md` / `AGENTS.override.md` | `CLAUDE.md` |
| `$<skill-name>` invocation syntax | `/<skill-name>` |
| `where-agents-md` cross-references | `where-claude` |
| `audit-agent-docs` cross-references | `audit-claude-md` |
| Codex config paths (`~/.codex/`, `$CODEX_HOME`) | Claude config paths (`~/.claude/`) |
| "Codex" when referring to the product/tool | "Claude Code" |
| "AGENTS" when used as a generic concept for instruction files | "CLAUDE.md" |

Show the adapted content to the user and ask for approval before writing.

Write to `global/claude/skills/<name>/SKILL.md` only after approval.

### 4. Adapt agents (for each approved agent)

Read `global/codex/agents/<name>.toml`. Extract:
- `name` — use as-is (convert underscores to hyphens for kebab-case)
- `description` — use as-is
- `developer_instructions` — becomes the Markdown body
- `sandbox_mode = "read-only"` → explicit `tools` list (Read, Glob, Grep; add WebSearch/WebFetch only if the instructions reference web access)
- `model_reasoning_effort = "medium"` → `model: haiku`; `"high"` → omit (default Sonnet)

Write `global/claude/agents/<name>.md` in this shape:

```markdown
---
name: <kebab-name>
description: <description from TOML>
tools:
  - Read
  - Glob
  - Grep
---

<developer_instructions content, with Codex→Claude product references fixed>
```

Flag the output as needing human review before writing — TOML → Markdown is a lossy
transformation and the instructions may contain Codex-specific concepts.

### 5. Run install.sh

After all approved writes:

```bash
./install.sh
```

Report which symlinks were created.

### 6. Wrap up

Tell the user:
- Which items were ported (with their destination paths)
- Which items were skipped and why
- Remind them to restart Claude Code for new `/commands` to appear in autocomplete

## Guardrails

- Never overwrite an existing file in `global/claude/` — skip with a warning if the target already exists.
- Never modify any file under `codex/` — it is read-only source for this skill.
- Always show the adapted content and get per-item approval before writing.
- TOML agent → Markdown is inherently lossy: flag it explicitly; do not claim the conversion is complete.
- Names that differ between products (e.g., `where-agents-md` vs `where-claude`) must be noted — do not silently rename without telling the user.
- Do not run `./install.sh` until at least one file has been written.
