Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00057 | $0.00562 |
| Opus 5 | $0.00028 | $0.00281 |
| Sonnet 5 | $0.00011 | $0.00112 |
| Haiku 4.5 | $0.00006 | $0.00056 |
Grade A, and why
aio-patch-anchor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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.jsalready extracted (aio-patch-extractrun before this)node(withacorn,acorn-walk,eslint-scopeinstalled intools/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
oldfield. - Run
/aio-claude-toolkit:aio-patch-anchor find "<fragment>"to find the new location. - Update
tools/pipeline/patches.jsonoldfield 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).
Implementation
Invokes ${CLAUDE_PLUGIN_ROOT}/skills/aio-patch-anchor/scripts/anchor.sh "$@".
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

aio-patch-anchor is a skill published in the GitHub repository aiocean/claude-plugins (4 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 562 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
