agent-red-teaming

agent-red-teaming is a skill for Codex from seb1n/awesome-ai-agent-skills. It costs 82 tokens per session (2,062 once invoked), scanned A, original, MIT.

A structured process for safely testing an AI agent or multi-agent workflow with adversarial cases, such as attempts to bypass instructions or misuse tools. It requires written permission, a defined scope, limits, and a cleanup plan before testing a live target.

In plain words
What is it for?
Use it to assess prompt injection, excessive tool access, identity or handoff problems, memory risks, and external integrations. It helps produce rules of engagement and evidence-based findings.
Why use it?
It finds control and security failures without probing systems that have not been authorized for testing. It records the setup, evidence, stop conditions, and retests needed to verify fixes.

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

agent-red-teaming 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/score_campaign.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Agent Red Teaming

Find exploitable control failures without creating uncontrolled harm. Treat written authorization and rules of engagement as prerequisites for execution, not paperwork to complete afterward.

Inputs

Collect:

  • Named target owner and explicit authorization for the exact systems to be tested
  • Target identifiers, environment, accounts, endpoints, models, versions, and a reproducible configuration digest
  • Start/end time, tester identities, source addresses, rate and cost limits, and emergency contact
  • In-scope objectives and out-of-scope systems, tenants, data, techniques, and effects
  • Agent architecture, tools, privileges, memory, retrieval, handoffs, identities, and external integrations
  • Protected assets, security requirements, prior incidents, existing controls, and expected benign tasks
  • Approved synthetic data, canary values, test destinations, cleanup plan, and evidence-handling rules

If target-specific authorization or scope is missing, stop at a non-executable assessment plan. Do not probe a live target to infer scope.

Output contract

Deliver:

  1. Signed-off or explicitly pending rules of engagement with scope, constraints, stop conditions, contacts, and cleanup duties
  2. A system and privilege map plus prioritized threat hypotheses
  3. A machine-readable, owner-approved campaign plan with unique case IDs, targets, environment, configuration digest, tester subjects, authorization reference, time window, limits, stop conditions, cleanup duties, protected invariants, and safe oracles
  4. Execution records tied to an approved case ID and unique test ID, with matching target/configuration, timestamps, observed limits, structured evidence, and cleanup traceability
  5. Deduplicated findings with reproducibility, evidence, impact, likelihood, preconditions, root control failure, and remediation
  6. Plan-denominator campaign metrics that distinguish passes, failures, blocked cases, errors, missing records, and tests not run
  7. Retest results, residual risk, cleanup confirmation, and any incident or scope deviation

Changes

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.
