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 | $0.00000 | $0.00306 |
| Opus 5.5 | $0.00000 | $0.00122 |
| Sonnet 5.5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
ui-evidence-bundle 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 2d 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
UI evidence bundle
Use this skill after a deterministic UI acceptance run to preserve a small, inspectable record after large CI artifacts expire.
Contract
- Stage only the evidence files safe to preserve publicly.
- Write a JSON spec with exact repository, issue, 40-character source SHA, surface, scenario, verdict, checks, files, and optional exact-desktop
buildprovenance. - Run
python .agents/skills/ui-evidence-bundle/scripts/ui-evidence-bundle.py create SPEC OUTPUT.zip. - Publish selected files or the bundle to content-addressed storage separately, then record their
ipfs://or HTTPS URLs in the spec. This tool never handles credentials or publishes content. - Before citing a bundle, run
... verify OUTPUT.zipand preserve the printed bundle SHA-256.
The byte-stable ZIP uses fixed metadata and stored members; verify with --expected-source-sha SHA when consuming evidence from another party. It contains canonical manifest.json, derived summary.md, and only explicitly staged evidence. Verification rejects source mismatches, dangling references, unsafe paths, undeclared members, and changed bytes. A valid bundle proves integrity and internal source consistency; it does not prove the acceptance assertion was well designed.
See references/ui-evidence-bundle.schema.json for the input shape. For packaged Electron, copy the provenance fields from an exact-desktop-artifact acquire result and set build.sourceSha to the same exact source SHA.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ui-evidence-bundle is a skill published in the GitHub repository seed-hypermedia/seed (59 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 306 tokens. 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 2026-10-27.

Adversarial design critique of the current work. Render it, look at it, and argue for rejection. Run after the gates are green, never instead of them.
