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.

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 | $0.00077 | $0.01014 |
| Opus 5 | $0.00039 | $0.00507 |
| Sonnet 5 | $0.00015 | $0.00203 |
| Haiku 4.5 | $0.00008 | $0.00101 |
Grade C, and why
agent-bom-discover-gcp scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- "~/.config/gcloud/application_default_credentials.json" What it actually says
agent-bom-discover-gcp
Use this skill to collect GCP AI and workload inventory as schema-valid agent-bom inventory. Default to discover-only: write JSON to an operator-selected path and stop.
Guardrails
- Use only operator-approved projects and read-only credentials.
- Do not request or display service account private keys, OAuth refresh tokens, or bearer tokens.
- Do not modify GCP resources. This workflow is discovery-only.
- Write inventory only to a path the operator chose.
- Treat AI-generated prose as non-authoritative; schema-validated inventory JSON is the evidence.
Workflow
python examples/operator_pull/gcp_inventory_adapter.py \
--project "$GOOGLE_CLOUD_PROJECT" \
--region us-central1 \
--source gcp-skill-invoked \
--discovery-method skill_invoked_pull \
--output gcp-inventory.json
Scan only when the operator asks for findings:
agent-bom scan --inventory gcp-inventory.json --format json --output agent-bom-gcp-findings.json
Evidence Contract
The emitted inventory carries discovery_provenance.source_type: skill_invoked_pull, observed_via: skill_invoked_pull, gcp_sdk, sanitized
metadata.permissions_used, and redacted credential material. If schema
validation fails, stop and fix the inventory instead of scanning a best-effort
summary.
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.

agent-bom-discover-gcp is a skill published in the GitHub repository msaad00/agent-bom (31 stars, last pushed today), licensed Apache-2.0. It adds 77 tokens to every session and 1,014 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
