What actualize does

actualize compares the .fpf/ knowledge base with Git changes after the commit stored in .fpf/.baseline. When that baseline file is absent, it starts from the repository’s initial commit. It examines changed-file names and statistics, then checks project configuration against .fpf/context.md.

The skill reads evidence in .fpf/evidence/, inspects each carrier_ref, and flags records tied to changed files. It also follows links from files in .fpf/decisions/ to their evidence and hypotheses to identify decisions that may need review. It then updates .fpf/.baseline and produces a structured report.

Git and an .fpf/ directory are required because the skill compares repository changes with that knowledge base. Set up FPF before relying on this check.

What it helps with

  • compare an FPF knowledge base with Git history
  • flag evidence linked to changed files
  • identify decisions that may need re-evaluation
  • write a new baseline to .fpf/.baseline

Example prompts for the agent

  • Run the actualize skill for the current repository.
  • Use actualize to find stale evidence after code changes.
  • Run actualize and update .fpf/.baseline after the review.

What does actualize do?

It compares the FPF knowledge base with Git changes, checks whether evidence is still current, and reviews related decisions. It writes an updated baseline after the check.

Which files does actualize inspect?

It checks changes to configuration such as package.json, go.mod, Cargo.toml, requirements.txt, Dockerfile, docker-compose.yml, and .env.example. It also reads records in .fpf/evidence/ and .fpf/decisions/.
