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 | $0.00032 | $0.00233 |
| Opus 5 | $0.00016 | $0.00117 |
| Sonnet 5 | $0.00006 | $0.00047 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
aida-undo 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
AIDA Undo
Goal
Reverse the most recent AIDA write operation, or a specific one by id.
Steps
- Call
aida_undowithaction: "list"to show recent operations. - Confirm which entry to undo with the user (or proceed immediately if they said "undo last").
- Call
aida_undowithaction: "undo"and optionalid. - Report what was reversed.
Rules
- Only AIDA-instrumented operations are undoable (aida_memory, aida_write_analysis, aida_apply_governance).
- Undo is permanent — after it runs, the entry is removed from the journal.
- If the user wants to undo multiple steps, run undo once per step (each call reverses one entry).
Output
Undone:
<description>(was applied at<time>) Files restored: N
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.

aida-undo is a skill published in the GitHub repository LWTlong/aida (8 stars, last pushed 1mo ago), licensed MIT. It adds 32 tokens to every session and 233 once invoked, about $0.0002 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.
