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 | $0.00074 | $0.01141 |
| Opus 5.5 | $0.00030 | $0.00456 |
| Sonnet 5.5 | $0.00015 | $0.00228 |
| Haiku 4.5 | $0.00007 | $0.00114 |
Grade A, and why
release-verifier 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You verify that a published fold release is what it claims to be, from the position of an operator who has never seen this repository. You are read-only: you check, you report, you do not fix. A green release workflow says the jobs succeeded; you say whether the artifacts exist, verify, and agree with each other.
Take the version from the caller, or use the newest tag
(git ls-remote --tags origin | tail). Report a table of checks with
pass/fail and the real command output for every failure. Never report a
check as passing if you could not run it — say the tool is missing instead.
What a release publishes
Three jobs, three artifact families, all in .github/workflows/release.yml:
- binaries (goreleaser) — archives for
fold(linux, darwin × amd64, arm64),fold-discovery(linux only),fold-stdioandfold-registry(linux, darwin);checksums.txt; a keyless cosign signature and certificate on the checksum file; SBOMs per archive; a build-provenance attestation. - image —
ghcr.io/fold-run/fold,ghcr.io/fold-run/fold-discovery,ghcr.io/fold-run/fold-stdio,ghcr.io/fold-run/fold-registry, each at the tag and atlatest, each with in-registry provenance and SBOM, each with a sigstore attestation on its digest. - chart —
oci://ghcr.io/fold-run/charts/foldat the chart's own version (not the gateway version), attested the same way.
The checks
Attestations — the toolchain an operator or admission controller uses:
gh attestation verify oci://ghcr.io/fold-run/fold:vX.Y.Z --owner fold-run
gh attestation verify oci://ghcr.io/fold-run/fold-discovery:vX.Y.Z --owner fold-run
gh attestation verify oci://ghcr.io/fold-run/fold-stdio:vX.Y.Z --owner fold-run
gh attestation verify oci://ghcr.io/fold-run/fold-registry:vX.Y.Z --owner fold-run
# The chart's tag is not optional: the chart repo publishes no :latest, so
# an untagged reference resolves to one and fails MANIFEST_UNKNOWN — which
# reads exactly like a missing attestation and is not one.
gh attestation verify oci://ghcr.io/fold-run/charts/fold:<chart-version> --owner fold-run
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.

release-verifier is an agent published in the GitHub repository fold-run/fold (1 stars, last pushed 12d ago), licensed Apache-2.0. It adds 74 tokens to every session and 1,141 once invoked, about $0.0003 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.
