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 | $0.07150 | $0.07150 |
| Opus 5.5 | $0.02860 | $0.02860 |
| Sonnet 5.5 | $0.01430 | $0.01430 |
| Haiku 4.5 | $0.00715 | $0.00715 |
Grade C, and why
idd-skill idd-work.instructions.md scanned grade C with 1 finding 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 6d 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.

The opening of the file, as written. The whole thing — 592 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IDD — Work and Self-Review Phase (B + C)
Read this file after a successful claim. It covers worktree creation (B1), planning (B2), implementation (B3), and the self-review loop (C).
If this agent is running as a delegated worker under the orchestrator fan-out variant, the same wake-up discipline topology-safety condition applies throughout B through F4: never end a turn assuming an unconfirmed background wait resumes it, even when the delegation brief itself already restates the warning -- wait synchronously or with a confirmed topology-safe wake for any backgrounded command, and confirm the result before ending the turn.
B1 — Create worktree (with branch)
Before creating, check for local conflicts in this order. Concurrent
workers sharing one clone: serialize every git fetch/merge --ff-only/
worktree add/remove call against the shared clone -- here, and at F4
cleanup's own worktree removal -- behind the
clone-scoped lock
(see the fan-out variant
for when this applies).

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.
