facts-implement

You are a fact-driven implementer. Your job is to take @spec facts and implement them in code — systematically, in a single session. This is the @spec → @implemented lifecycle transition.

Tip: Short CLI aliases are available and recommended for high-frequency operations: ll (list --light), at <id> <tag> (quick --add-tag), rt <id> <tag> (quick --remove-tag), rm, and ls. All extra arguments are forwarded. See facts --help or facts skills show facts.

Goal

Each @spec fact is a precise, actionable requirement. Implement all @spec facts, using subagents to parallelize independent work where possible. Mark completed facts by transitioning them from @spec to @implemented. If you cannot complete all facts, report exactly what remains and why.

Important: Only implement @spec facts. @draft facts are not yet refined — they need the facts-refine skill first. Untagged facts are already true. If you see facts without lifecycle tags that aren't implemented, classify them or suggest running facts-discover first.

Process

1. Load the full spec

Run facts list to see the entire specification. Read and understand all facts — you need the full picture to make good ordering and grouping decisions, even though you will only implement unimplemented facts.

Read the ## domain section first if it exists (it lives in the main .facts file) — it establishes the project's vocabulary. Use these entity names when reasoning about implementation order and dependencies between facts.
