Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00068 | $0.03699 |
| Opus 5 | $0.00034 | $0.01850 |
| Sonnet 5 | $0.00014 | $0.00740 |
| Haiku 4.5 | $0.00007 | $0.00370 |
Grade A, and why
driver-test-runner scanned grade A 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Driver Test Suite Runner
Methodically run the RivetKit driver test suite one file group at a time across the native (NAPI) and wasm runtimes, tracking progress in ~/.agents/notes/driver-test-progress.md.
Arguments
The skill accepts optional arguments:
reset— Clear progress and start from the beginning.resume— Pick up from where we left off (default behavior).only <file>— Run only a specific test file group (e.g.,only actor-conn).from <file>— Start from a specific file group, skipping earlier ones.runtime <native|wasm|both>— Which runtime(s) to run (default:both).encoding <bare|cbor|json>— Override encoding (default:bare).registry <static>— Override registry type (default:static).
Runtime Matrix
The driver suite runs over a runtime × SQLite-backend × encoding matrix defined in rivetkit-typescript/packages/rivetkit/tests/driver/shared-matrix.ts. The runtime dimension has two values:
native— NAPI bindings (@rivetkit/rivetkit-napi). Pairs withsqlite=localfor the primary native driver pass.wasm— WebAssembly bindings (@rivetkit/rivetkit-wasm). Wasm cannot use local SQLite; it must pair withsqlite=remote(executes SQL through the engine over the wire).
The skill defaults to running each test file twice: once on native/local and once on wasm/remote, each at encoding=bare. A file is checked off only when both runtimes pass.
The test harness does not read environment variables for matrix selection. Always select matrix cells with Vitest -t using the full inner describe name: runtime (<runtime>) / sqlite (<backend>) / encoding (<encoding>).
How It Works
0. Anchor the reference before fixing parity bugs
If a RivetKit driver test fails because native or Rust behavior diverges from the old runtime, do this before inventing a separate debugging workflow:
- Treat
rivetkit-typescript/packages/rivetkitdriver tests as the primary oracle. - Compare the failing behavior against the original TypeScript implementation at ref
feat/sqlite-vfs-v2usinggit showorgit diff. - Patch native/Rust to match the original TypeScript behavior.
- Rerun the same TypeScript driver test before adding any lower-level native tests.
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.

driver-test-runner is a skill published in the GitHub repository rivet-dev/actors (6,096 stars, last pushed 3d ago), licensed Apache-2.0. It adds 68 tokens to every session and 3,699 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

lint-js
Lint JS/TS code only. Use before opening a PR when only JavaScript or TypeScript files were changed (no Rust).
feishu
Work with Feishu or Lark bots, docs, sheets, bitables, approval flows, and OpenAPI/MCP setup without hardcoding credentials.
interview
Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.
test
Detect the project’s test stack, run the narrowest useful tests, create tests when authorized, and report coverage/gaps honestly.
verify
Exercise the real app/API/CLI and collect observable evidence; tests alone do not count as end-to-end verification.
