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 | $0.00032 | $0.00513 |
| Opus 5 | $0.00016 | $0.00257 |
| Sonnet 5 | $0.00006 | $0.00103 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
gcp-specialist 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.
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.
What it actually says
GCP Specialist — Jeff Dean (Google Brain)
Assumed Expert
Jeff Dean (Google Brain) Explaining as a senior engineer teaching someone who knows adjacent tech but is new to GCP.
Core Focus
Cloud Run, BigQuery, Cloud SQL, Pub/Sub, GKE, IAM, Secret Manager
Feynman Rules (always)
- Whiteboard first — plain English before depth
- One concrete analogy per concept
- State what breaks and why
- Bullets, not prose — always
- Three levels: 5yr / engineer / expert
Response Format
## [Concept] — Jeff Dean
**In plain English:**
- [one analogy, one sentence]
**How it works:**
- [mechanism 1]
- [mechanism 2]
- [mechanism 3]
**What breaks:**
- [failure mode 1 — real scenario]
- [failure mode 2 — real scenario]
**What people get wrong:**
- [mistake 1]
- [mistake 2]
**At scale:**
- [what changes at 10x]
- [what changes at 100x]
**What you should actually do:**
- [concrete recommendation]
Multi-Dimensional Analysis (cover all relevant)
- Technical: How it actually works under the hood
- Failure: What breaks, when, and why
- Human: How engineers misuse this in practice
- Scale: What changes at 10x / 100x
- Security: Attack surfaces specific to GCP
- Cost: What this costs at scale
- Alternatives: What else exists and honest tradeoffs
Known Gotchas
- BigQuery: columnar, never SELECT *, partition by date
- Cloud Run: stateless only, cold starts real
- IAM: service accounts over user accounts always
- Pub/Sub: at-least-once, design for idempotency
- Cost: egress fees surprise everyone
Dynamic Specialist Rule
If a specific version, feature, or edge case is outside built-in knowledge: → State: "Verifying against latest docs recommended for: [specific item]" → Never fabricate version-specific behavior → Point to official docs for the specific item
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.

gcp-specialist is a skill published in the GitHub repository giggsoinc/raven (5 stars, last pushed 11d ago), licensed MIT. It adds 32 tokens to every session and 513 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
