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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00023 | $0.00944 |
| Opus 5 | $0.00012 | $0.00472 |
| Sonnet 5 | $0.00005 | $0.00189 |
| Haiku 4.5 | $0.00002 | $0.00094 |
Grade A, and why
cat-memory-recovery 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
🛡️ Cat-Memory-Recovery: Universal Snapshot Instructions
1. 6 Core Project Files (Major Protection Targets)
- Strategic Goals:
implementation_plan.md - Progress Records:
walkthrough.md - Real-time Tasks:
task.md - AI Brain:
.agents/SKILL.md - Manuals:
.agents/workflows/*.md - Blueprint:
README.md
2. Snapshot Recording Policy (Zero-Silence)
- Zero Loss: Capture 100% of the original content. Do not summarize.
- Multiple Files: Create individual snapshot blocks for each modified file.
- Trigger Condition: Only trigger when any of the 6 core files are written/modified.
3. Snapshot Format Specification
<!-- [CAT_SNAPSHOT_START: filename]
[Full Content of the File]
[CAT_SNAPSHOT_END: filename] -->
4. Smart Snip Protocol (Season 2+)
- Semantic Summarization: If the conversation becomes too long, identify completed task blocks.
- Tool Output Collapse: Replace long outputs with a concise [CAT_SNIP_SUMMARY].
- Preserve Decisions: Never snip "Design Decisions" or "User Approvals".
What ships with it
5 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.

cat-memory-recovery is a skill published in the GitHub repository bluesaurel/antigravity-cat-toolkit (2 stars, last pushed 5mo ago), licensed MIT. It adds 23 tokens to every session and 944 once invoked, about $0.0001 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.
