Aio Patch Anchor

Find and navigate anchors in the extracted cli.js — wraps tools/cli-nav/{find-anchors,navigate,build-explorer}.cjs (acorn-based AST navigator). Used primarily for drift recovery when Claude version bumps shift the location of anchored patch points.

File contents

aio-patch-anchor — anchor discovery & AST navigation for cli.js

Goal

Help write durable patches by surfacing structural / textual anchors in the extracted dist/<arch>/cli.js. Bridge between "I want to patch X" and "what's the invariant string near X I can anchor on".

Usage

/aio-claude-toolkit:aio-patch-anchor find <pattern>      # grep + AST proximity hits
/aio-claude-toolkit:aio-patch-anchor navigate --fn <name>   # walk AST around a function
/aio-claude-toolkit:aio-patch-anchor navigate --at <line>   # show AST context at a line
/aio-claude-toolkit:aio-patch-anchor explorer            # render single-file HTML browser of cli.js

Requires

Scaffolded project (walk-up sentinel)
dist/<arch>/cli.js already extracted (aio-patch-extract run before this)
node (with acorn, acorn-walk, eslint-scope installed in tools/cli-nav/node_modules/)

If tools/cli-nav/node_modules is empty, anchor.sh runs bun install (preferred) or npm install in tools/cli-nav/ first.

Drift recovery workflow

Compile reports MISSING patch IDs.
For each missing ID, take a 3-5 word fragment of the patch's old field.
Run /aio-claude-toolkit:aio-patch-anchor find "<fragment>" to find the new location.
Update tools/pipeline/patches.json old field with the surrounding invariant content.
Re-run /aio-claude-toolkit:aio-patch-compile (transitive — extract first if cli.js stale).

See docs/repatching-playbook.md (step-by-step re-anchoring recipe).
