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 5.1 | $0.00051 | $0.00740 |
| Opus 5 | $0.00026 | $0.00370 |
| Sonnet 5 | $0.00010 | $0.00148 |
| Haiku 4.5 | $0.00005 | $0.00074 |
Grade A, and why
tauri-command-contract 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 12d 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.

Tauri Command Contract
Use this skill when a task crosses the frontend/Rust boundary through Tauri commands.
When to Use
- Adding or changing
#[tauri::command]handlers insrc-tauri - Modifying frontend
invokecallsites or typed command wrappers - Changing command payload/response DTOs or error format
- Refactoring command registration (
generate_handler!) and command naming - Reviewing boundary regressions where frontend and Rust drifted out of sync
When NOT to Use
- Task is only about window controls/titlebar behavior with no command contract changes (use
tauri-window-shell) - Task is purely internal Rust logic with no Tauri command boundary
- Task is only UI styling and interaction with no invoke path
Delivery Workflow
Tauri command contract progress:
- [ ] Step 1: Inventory touched commands and callsites
- [ ] Step 2: Define explicit DTOs for request/response at boundary
- [ ] Step 3: Normalize error envelope and map Rust errors intentionally
- [ ] Step 4: Verify command registration and frontend wrapper alignment
- [ ] Step 5: Add/adjust boundary tests (Rust + frontend invoke surface)
Core Rules
- Treat each command as a versioned contract, not an internal function leak.
- Keep command handlers thin: validate/parse, delegate to service, map output.
- Avoid anonymous/loosely typed payloads at boundary; use explicit serializable DTOs.
- Do not return raw infrastructure errors directly to frontend.
- Keep command names stable and intention-revealing; avoid accidental renames.
Contract Pattern
- Rust side:
- define transport DTOs and explicit result shape
- map domain/infrastructure errors to stable boundary error variants
- Frontend side:
- centralize invoke wrappers instead of scattering raw
invoke(...)strings - type wrappers to shared command DTO shapes
- centralize invoke wrappers instead of scattering raw
Boundary checklist:
- [ ] Command name unchanged or migration path documented
- [ ] Request DTO shape explicit
- [ ] Response DTO shape explicit
- [ ] Error envelope stable and parseable by frontend
- [ ] Frontend wrapper updated in same change
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.

tauri-command-contract is a skill published in the GitHub repository JakubMikolajek/codex-skills-collection (5 stars, last pushed 7d ago), licensed MIT. It adds 51 tokens to every session and 740 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 2026-08-31.
