Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00147 | $0.00893 |
| Opus 5.5 | $0.00059 | $0.00357 |
| Sonnet 5.5 | $0.00029 | $0.00179 |
| Haiku 4.5 | $0.00015 | $0.00089 |
Grade A, and why
aio-agent-threats-reference 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 17d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI-Agent Attack-Vector Reference
Semantic-search lookup over the aio-agent-threats corpus. This skill retrieves and reads; for a guided engagement workflow use the sibling aio-agent-threats advisor skill.
The corpus lives in the sibling skill folder ${CLAUDE_PLUGIN_ROOT}/skills/aio-agent-threats/: volume-NN-*/ directories, with search scripts in scripts/.
Lookup Workflow
1. Search by meaning
cd "${CLAUDE_PLUGIN_ROOT}/skills/aio-agent-threats/scripts" && npx tsx search-vectors.ts "<what you're looking for>" --top 6 --json
# first run only, if embeddings.json is missing: npx tsx build-embeddings.ts
Returns ranked {title, volume, file, score}. Read the full file for the top hits — the file field is the path under ${CLAUDE_PLUGIN_ROOT}/skills/aio-agent-threats/.
2. Browse a volume
List and read articles directly:
ls "${CLAUDE_PLUGIN_ROOT}/skills/aio-agent-threats/volume-03-tool-and-mcp/"
| Vol | Focus |
|---|---|
| 01 foundations | attack-surface taxonomy, instruction/data channel, kill chain, OWASP/NIST crosswalk, trust boundaries |
| 02 prompt-injection | direct, indirect, cross-modal, system-prompt leakage, obfuscation, delivery |
| 03 tool-and-mcp | tool poisoning, rug-pull, shadowing, line-jumping, excessive agency, MCP CVEs |
| 04 memory-and-context | MINJA, AgentPoison, RAG poisoning, persistent false beliefs, cross-session, misattribution gap |
| 05 multi-agent | contagious poisoning/worms, A2A trust, orchestrator hijack, cascading failures, protocol attacks |
| 06 jailbreak-evasion | Crescendo/STAC, Echo Chamber, roleplay/DAN, encoding/GCG, many-shot, policy puppetry |
| 07 supply-chain-exfil | coding-agent weaponization, repo poisoning, exfil channels, real incidents, espionage case, model supply chain |
| 08 defense-hardening | detection, spotlighting, dual-LLM/CaMeL, least-privilege, provenance/attestation, defense-in-depth |
3. Read the article
Each article carries: Core Concept · Origin/First Seen · How It Works · Attack Surface · Weaponization (lab) · Real-World Instances · Detection · Mitigations · Related Vectors · References. Every factual claim carries a source URL and a HIGH/MEDIUM/LOW confidence label — carry that label through into whatever you report.
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-agent-threats-reference is a skill published in the GitHub repository aiocean/claude-plugins (4 stars, last pushed 16d ago), licensed MIT. It adds 147 tokens to every session and 893 once invoked, about $0.0006 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 2026-10-26.
