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 | $0.00189 | $0.00189 |
| Opus 5.5 | $0.00076 | $0.00076 |
| Sonnet 5.5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
google-keyword-planner-mcp keyword-contracts.instructions.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 17d 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
Treat C# and Go as implementations of the same functional API contract while preserving their documented legacy argument formats. Temporary divergence requires evidence-backed tracking issues and companion implementation PRs.
Use the shared synthetic v25 response fixtures in testdata/google-ads/v25
from both test suites. Update them against authoritative Google API definitions,
not the current implementation. Preserve optional metric presence and assert
nonempty results so an incorrect response key cannot pass unnoticed.
Parse captured JSON before asserting embedded query strings; serializers may
escape quotes without changing their semantic value.
Coordinate concurrency tests with barriers, cancellation and fake time, not sleep-based ordering assumptions. Verify cancellation never returns partial forecasts as success. Planning concurrency does not replace customer-level quota pacing.
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.
