aio-agent-threats-reference

aio-agent-threats-reference is a skill for Claude Code from aiocean/claude-plugins. It costs 147 tokens per session (893 once invoked), scanned A, original, MIT.

A semantic search and reading tool for an encyclopedia of AI-agent attacks and defenses. Semantic search finds articles by meaning rather than requiring an exact keyword.

In plain words
What is it for?
Use it to research prompt injection, MCP or tool poisoning, memory poisoning, multi-agent attacks, jailbreaks, coding-agent supply-chain risks, and defensive techniques.
Why use it?
It helps you locate the full article on a particular threat or defense without browsing every volume. It is intended for lookup, not for guiding a complete security engagement.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

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.

Security

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.
