# First Tree Read ## Purpose Read the Context Tree applicable to the current task before acting. This skill is read-only: it uses `first-tree tree tree` to find relevant tree files, then uses the agent's native file-reading capability to read their content and summarize the constraints that matter for the user's task. A BYO task first activates one exact-commit snapshot; all selectors, soft-link traversal, and file reads for that task stay inside it. Use `first-tree-write` for tree writes from a source artifact. An explicit request to audit stored normal content on the default branch belongs to `context-tree-audit`; do not start this task-scoped read workflow first. Do not use this skill for a Cloud Context Reviewer wake-up or an explicit request to review a Context Tree PR/MR. `context-tree-review` has exclusive precedence for its supported GitHub PR or GitLab MR path and reads only from its detached, validated PR-head snapshot; running this workflow first would refresh and inspect the main tree checkout instead. Do not use this skill for an explicit broad audit of the whole tree, a domain, or selected stored normal paths. `context-tree-audit` has exclusive precedence and owns the stable default-branch snapshot, validate-first discovery, and finding routing. ## Authority Boundary Apply the generated Context Tree Policy's content classes and drift-authority rules before treating a file as current truth. Normal content is the canonical decision/constraint source; non-no...
