Context Tree Audit

Purpose

Audit a stable snapshot of stored normal content on the bound Context Tree's actual binding branch and route each evidence-backed finding to the smallest safe follow-up.

The workspace-generated AGENTS.md / CLAUDE.md Context Tree Policy is the only content-policy and authority baseline. Apply it directly; do not recreate its definitions or rules in this skill. If the policy or binding is missing, stop and report the environment gap.

Trigger Boundary

Use this skill only when a human explicitly asks for a broad stored-tree audit or names a domain or set of normal paths to audit. This trigger is exclusive: do not run first-tree-read first and expand a task-scoped read into an audit.

Do not use this workflow for a concrete source artifact that should be written to the tree, a Context Tree pull request or merge request review, ordinary task context, or an empty-tree setup. Those remain owned by their dedicated skills.

Choose the execution mode from the request:

• Report-only (default): a request to audit, inspect, or report grants read-only authority. Perform no commit, push, pull request, merge request, issue, tracked ask, or other external mutation; report findings and recommended routes in the completion response.
• Maintenance: select this only when the human explicitly asks to maintain, fix, or create follow-up artifacts. Mutation authority extends only to the requested artifact kinds. High-confidence local findings may produce one focused artifact per coherent finding group. Nothing is merged automatically.

Stable Snapshot

1. Read .first-tree/workspace.json and the generated Tree Location section. Resolve the bound tree checkout, upstream, and actual binding branch. Use the branch declared in Tree Location; never assume main or substitute the checkout's current branch. Fail closed on a missing binding, repository mismatch, or ambiguous branch.
2. From the bound checkout, inspect first-tree tree tree --help before using its current selectors.
3. Fetch the bound upstream branch and resolve its exact remote HEAD SHA. If freshness cannot be confirmed because of network, permission, or remote identity failure, do not claim a current audit and do not create a semantic fix.
4. Create a uniquely named, agent-owned detached worktree at that exact SHA. Never switch or edit the main tree checkout and never reuse an unowned path.
5. Report the repository, branch, exact SHA, requested scope, and execution mode. Keep all discovery reads fixed to this snapshot.
6. In the registered, clean detached worktree, run the selected first-tree tree tree --no-pull ... command and confirm its HEAD is still the exact audited SHA. Never resolve the audit scope from the mutable main checkout after the snapshot exists.
7. In the detached worktree, run first-tree tree verify --json before any semantic node read. Record validator failures as mechanical findings and do not hide them inside semantic conclusions.
8. If validation passes, read only the scoped normal nodes plus the minimum parent, sibling, relationship, and source evidence needed to judge them under the generated policy.
9. Remove the detached worktree through git worktree remove when finished. Never use --force; a dirty snapshot is an integrity failure.
