What it costs to keep this loaded
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 | $0.00061 | $0.00299 |
| Opus 5 | $0.00030 | $0.00150 |
| Sonnet 5 | $0.00012 | $0.00060 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
case 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 10d 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
Retired — Do Not Use
This workflow is permanently disabled for new PuPu work.
- Do not create or modify anything under
.claude/court/cases/. - Do not assign code-owner or court roles, request owner confirmations, open handoffs or hearings, or create proposal/ruling/acceptance records.
- Historical court, codex, agent, and supporting script files are read-only history. They do not authorize or block current work.
- For release work, use the smallest matching skill:
release-open-sprint,release-draft-ticket,release-refine-ticket,release-feature-audit, orrelease-close-sprint. - For implementation, use the Release issue, a direct Plan when needed, impact analysis, tests, and evidence. Cross-boundary work follows
.claude/rules/cross-boundary-contract-gate.mdwithout any role or court mechanism.
If a user explicitly asks to restore this retired workflow, stop and request an explicit update to the repository's active CLAUDE.md and AGENTS.md instructions. Do not infer restoration from legacy terminology or historical references.

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.

case is a skill published in the GitHub repository haoxiang-xu/PuPu (36 stars, last pushed yesterday), licensed Apache-2.0. It adds 61 tokens to every session and 299 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
