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 | $0.00049 | $0.01237 |
| Opus 5.5 | $0.00020 | $0.00495 |
| Sonnet 5.5 | $0.00010 | $0.00247 |
| Haiku 4.5 | $0.00005 | $0.00124 |
Grade A, and why
create-version-snapshot 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Version Snapshot
You are creating a new SDK version snapshot. This involves parsing the Clubhouse app's source types, diffing against the previous version, and generating a complete new SDK version directory.
Step 1: Determine the target version
If a version number was provided via $ARGUMENTS, validate it. Otherwise, ask the user.
- Read
sdk/versions.jsonto find the currentlatestversion - Validate the target version is greater than the current latest (use semver-style comparison on the version strings, e.g. "0.6" > "0.5")
- If invalid, explain and ask again
Step 2: Locate the Clubhouse source
Ask the user for the path to the Clubhouse application source code, or reuse a previously provided path. The source of truth is:
<source-path>/src/shared/plugin-types.ts
Verify this file exists before proceeding. If it doesn't, ask for correction.
Step 3: Parse and diff
- Read the source
plugin-types.tsfrom the Clubhouse app - Read the previous version's
sdk/v{prev}/plugin-types/index.d.ts - Compare the two and identify:
- Added: New types, interfaces, methods, or properties
- Changed: Modified signatures, added optional fields, changed types
- Removed: Deleted types, interfaces, methods, or properties
- Present a summary to the user in a clear table format:
API Changes: v{prev} → v{new}
Added:
- api.foo.newMethod(args): ReturnType
- NewInterface
Changed:
- api.bar.existingMethod — added optional `options` parameter
- ExistingType — field `x` changed from string to number
Removed:
- api.baz.deprecatedMethod
- OldInterface
- Ask for confirmation before generating files
Step 4: Generate the new SDK version
On confirmation:
sdk/v{new}/plugin-types/
index.d.ts— The new type definitions, derived from the Clubhouse source. Add a header comment:/** * Clubhouse Plugin API — v{new} * * Type definitions for the Clubhouse plugin SDK. * Generated from the Clubhouse application source. * * @version {new} * @see https://github.com/Agent-Clubhouse/Clubhouse-Workshop */
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.

create-version-snapshot is a skill published in the GitHub repository Agent-Clubhouse/Clubhouse-Workshop (2 stars, last pushed 11d ago), licensed MIT. It adds 49 tokens to every session and 1,237 once invoked, about $0.0002 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.
