What Docs Impact Classifier does

Docs Impact Classifier classifies the documentation impact of a pull request diff into no change, in-place edit, or structural change. It uses deterministic path gates, symbol extraction, and a bounded LLM call to keep docs-sync costs low when no docs work is needed.

Docs Impact Classifier is cataloged under AI Engineering on DirSkills. Docs Impact Classifier comes from a repository tagged ai-agents, claude-code, codex-cli, context-engineering and github-copilot.

Documentation

README

Excerpt

docs-impact-classifier

Single responsibility: given a PR diff and the .apm/docs-index.yml corpus map, emit ONE classification verdict.

This skill is the cost gate for the entire docs-sync system. ~70% of PRs should exit at verdict no_change with zero panel spawn.

Architecture

This is a 3-layer funnel inside a single skill invocation:

L0 deterministic path gate -- pure file-path matching, no LLM.
L1 symbol extraction + corpus grep -- pure text processing, no LLM.
L2 LLM classifier -- bounded ~8 KB context envelope, 1 call.

The skill returns the verdict from the earliest layer that can decide.

This is the opening of the README. Read the full README on GitHub.
