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 5.1 | $0.00036 | $0.00299 |
| Opus 5.5 | $0.00014 | $0.00120 |
| Sonnet 5.5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
acryl-change-plugin 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 24d 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
Change, improve or remove an ACRYL plugin
- Call acryl_list_plugins to find the plugin and the source directory it was installed from. If it is not listed the user may mean a built-in feature; say so instead of guessing.
- Read its files completely before editing, and the matching doc in {{pack}}/docs/README.md for the plugin type.
- Edit the source directory (never node_modules, never the pack). For UI changes edit client.js.
- Call acryl_install_plugin with the same directory: it updates in place, and host code changes take effect in the running app automatically ("hostReload": "automatic"). Read the result: if it has a "warning" the plugin could not be staged for automatic reload and host changes need an app restart ({{pack}}/docs/delivery/local-live.md); if it has a "next" note, tell the user to reload. A change to "inject" or the Config schema also needs a restart.
- To remove a plugin call acryl_remove_plugin. Confirm with the user first if they did not clearly ask for it. Report what changed and whether it is live; never claim it works without the tool result.
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.

acryl-change-plugin is a skill published in the GitHub repository acryldev/acryl (256 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 299 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-21.
