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 | $0.00027 | $0.00339 |
| Opus 5.5 | $0.00011 | $0.00136 |
| Sonnet 5.5 | $0.00005 | $0.00068 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade A, and why
smithers-flow-registry 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 21d 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
Flow registry
Read the registry README and filesystem router README before changing discovery or command projection. A flow directory has one entry file: flow.ts, flow.mdx, or SKILL.md; the descriptor records source and digest without importing its body. Registry list and warnings read one metadata snapshot. Do not execute a discovered flow to answer a catalog listing.
Executable registration is a separate boundary that loads the selected body, resolves its delegate, and supplies runtime layers. A TypeScript module may export layer beside its default flow; build its action implementations once in the scoped host context, retain named load refusals for unavailable services, and provide the built context to both flow registrations. The host owns the action table: modules export Declared.toLayer / AgentAction.layer directly, without providing Action.layerImplementations. Preserve warning receipts for refusals and the refresh path for edited entries. A host must provide services required by delegate success/error codecs even when the catalog erases their static requirements. Pack entries retain provenance and path confinement; verify name precedence, stale descriptors, and an edit during refresh in tests.
@smthrs/fs command listing is metadata-only, but its first Incur help/OpenAPI/MCP projection imports visible modules to publish input schemas. Keep that distinction explicit when claiming a discovery path runs no user code.
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.

smithers-flow-registry is a skill published in the GitHub repository smithersai/smithers (439 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 339 once invoked, about $0.0001 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 2026-09-25.
