Use whenever the task involves project documentation, architecture, design decisions, implementation plans, specs, worklogs, project memory, or any durable knowledge that should live in the repo. This includes reading or writing docs, querying prior decisions, checking doc health, reviewing history, updating AGENTS.md / CLAUDE.md / ARCHITECTURE.md, or organizing project knowledge. If the repo has AGENTS.md, CLAUDE.md, or .harnesskit/, treat HarnessKit as the default documentation workflow: read the entrypoint first, then use the CLI when query, context, checks, indexing, or history are useful.
