Builds pure string-transform functions that live in domain/formats/. Every function in this
layer is stateless, has no I/O, is a named export, and uses .js ESM import paths. Where a
forward transform exists, a lossless reverse transform must accompany it.

Codex install prompt
Install the "format" agent skill from https://github.com/ai-driven-dev/framework/tree/main/cli/.claude/skills/format. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Creates or modifies pure string-transform functions in domain/formats/. Use when adding a new format module (toml, markdown, json, placeholders, command), implementing a lossless round-trip transform and its inverse, or writing exhaustive unit tests for an existing pure function. Do NOT use for capability classes — use `capability` instead. Do NOT use for AI tool definitions — use `tool` instead. Do NOT use for I/O-bearing code — use `adapter` instead. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"ai-driven-dev-format","task":"Install format","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: cli/.claude/skills/format/SKILL.md. Confirm the source matches these instructions.
