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 | $0.00426 | $0.00426 |
| Opus 5.5 | $0.00170 | $0.00170 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
googlecloud-plugin AGENTS.md 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 1mo 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
AGENTS.md — GoogleCloud Plugin (Codex always-on adapter)
Human-led. Agent-powered. Built on Google Cloud.
Codex discovers this plugin's skills under .agents/skills/ and reads this file as the always-on contract for Google Cloud work. The skills carry the depth; this file carries the rules.
Design before generate
Restate the intent in one sentence before writing code. No GCP implementation without a design — route through the gate.
The gate (sequential — do not skip)
- Solution Gate —
solution-designer: objective vendor selection (GCP vs alternatives). Skip only if unambiguously GCP-only. - GCP Design Gate —
gcp-architect(+agent-architectfor agentic work): HLD/LLD + ADRs before code. - Security Gate —
gcp-security: least-privilege IAM, no secrets, Well-Architected security. Reviews the design. - Implementation — service skills; warn before every billable action.
- Quality Gate —
gcp-qarunsmake gate;agent-architectruns agent-eval for agentic work. - Operational Readiness Gate —
gcp-ops: SLO + alerting + runbook before production.
Non-negotiable safety rules
- Infer intent, never infer permission. A named human authorises anything consequential, billable, or irreversible.
- No credential values in any file — record location only.
- No public buckets or unauthenticated Cloud Run without gcp-security sign-off.
- Never pin a preview Gemini model ID; use GA IDs, reverify for the GEAP surface.
- GEAP naming in prose; legacy
vertex-ailiterals in code/URLs/Terraform.
Routing
See PLUGIN.md for the full routing table. New work → solution-designer; GCP design → gcp-architect; agentic systems → agent-architect.
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.

googlecloud-plugin AGENTS.md is an instructions file published in the GitHub repository jpantsjoha/googlecloud-plugin (4 stars, last pushed 2mo ago), licensed MIT. It adds 426 tokens to every session, about $0.0017 per session on Opus 5.5. 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.
