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 | $0.01763 | $0.01763 |
| Opus 5.5 | $0.00705 | $0.00705 |
| Sonnet 5.5 | $0.00353 | $0.00353 |
| Haiku 4.5 | $0.00176 | $0.00176 |
Grade A, and why
cliproxy-plugin-opencode-cloak AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
What this repo is
A C-ABI shared library, not a program. Single flat Go package main at the repo root, built with
-buildmode=c-shared and loaded via dlopen by a CLIProxyAPI host. func main() {} is intentionally
empty — never "fix" it. Read README.md for the product-level contract (activation gates, config
fields, division of labor with the host).
Commands
make build # go build -buildmode=c-shared -o bin/opencode-cloak.$EXT . (EXT auto: dylib/so/dll)
make test # go test ./... -count=1
make vet # go vet ./...
make fmt # gofmt -w .
CI (.github/workflows/ci.yml) runs, in order: gofmt check → go vet → go test → c-shared build,
on ubuntu-latest + macos-latest. The gofmt gate is test -z "$(gofmt -l .)" — any unformatted file
fails the build, so run make fmt before finishing.
Single test: go test -run TestName -v. There is no lint tool beyond gofmt + go vet.
Build constraints
- CGO is mandatory (
CGO_ENABLED=1);make buildrelies on the default being on. - Cross-compilation does not work.
GOOS=linux go buildon macOS fails inruntime/cgo. Release artifacts come from a 5-runner matrix in.github/workflows/release.yml(linux/darwin × amd64/arm64 plus windows/amd64), triggered by av*tag. Never try to produce another platform's library locally. bin/is gitignored;bin/opencode-cloak.his cgo-generated output, not source. The release build likewiserms the generated.hbefore packaging — the store installer rejects an archive that carries anything but the single dynamic library.

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.
