A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

```See INSTALL.md — review scripts/bootstrap.sh (sha-pinned) before running it yourself.The text {match} is the classic direct prompt-injection phrasing. Placed in a skill body that the agent reads as trusted instructions, it tries to make the agent abandon its prior rules and follow whatever comes next — a full system-prompt override.
ignore/disregard/forget … previous instructions sentence.Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Discovers MCP clients and servers across 22 AI tools, scans for CVEs, maps blast radius, runs cloud CIS benchmarks, checks OWASP/NIST/MITRE compliance, generates SBOMs, and assesses AI infrastructure against AISVS v1.0 and MAESTRO framework layers.

unknown — a CVE ID with no details is still a real finding. Report what is known; mark severity as unknown explicitly.cis_benchmark) — these make live API calls to AWS/Azure/GCP using the user's credentials.UNKNOWN severity as unresolved, not benign — it means data is not yet available, not that the issue is minor.Never do:
agents() autonomously on sensitive environments without user confirmation. The autonomous_invocation policy is restricted.Stop and ask the user when:
CRITICAL CVEs — present findings and ask whether to generate a remediation plan.OWASP AISVS v1.0 ships as a benchmark surface alongside the tag-mapped frameworks (9 verification checks).
This skill installs agent-bom from PyPI. Verify the redaction behavior before running with any config files:
# Step 1: Install
pip install agent-bom
# Step 2: Review redaction logic BEFORE scanning
# sanitize_env_vars() replaces ALL env var values with ***REDACTED***
# BEFORE any config data is processed or stored:
# https://github.com/msaad00/agent-bom/blob/main/src/agent_bom/security.py#L159
# Step 3: Review config parsing — only structural data extracted:
# https://github.com/msaad00/agent-bom/blob/main/src/agent_bom/discovery/__init__.py
# Step 4: Verify package provenance (Sigstore)
agent-bom verify agent-bom
# Step 5: Only then run scans
agent-bom agentsWhat is extracted: Server names, commands, args, and URLs from MCP client config files across 22 AI tools. What is NOT extracted: Env var values are replaced with ***REDACTED*** by sanitize_env_vars() before any processing. Only public package names and CVE IDs are sent to vulnerability databases. Cloud CIS checks use locally configured credentials and call only the cloud provider's own APIs.
