Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00097 | $0.02502 |
| Opus 5 | $0.00048 | $0.01251 |
| Sonnet 5 | $0.00019 | $0.00500 |
| Haiku 4.5 | $0.00010 | $0.00250 |
Grade A, and why
tauri-impl-security 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 10d 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.

Quick Reference
Security Architecture (Tauri 2)
| Layer | Mechanism | Configuration |
|---|---|---|
| Content Security Policy | Restricts resource loading in webview | app.security.csp in tauri.conf.json |
| Permissions | Define which IPC commands are allowed/denied | src-tauri/permissions/*.toml |
| Capabilities | Bind permissions to specific windows | src-tauri/capabilities/*.json |
| Scopes | Restrict what data commands can access | Within permission definitions |
| Isolation Pattern | Separate IPC from frontend context | app.security.pattern |
| Prototype Freeze | Prevent prototype pollution | app.security.freezePrototype |
Tauri-Specific Protocols
| Protocol | Purpose | CSP Directive |
|---|---|---|
tauri: |
Internal protocol for serving frontend assets | default-src |
asset: / https://asset.localhost |
Access bundled resources and filesystem assets | img-src, media-src |
ipc: / http://ipc.localhost |
IPC communication between frontend and Rust | connect-src |
Critical Warnings
NEVER set csp to null in production -- this disables all content security restrictions, exposing the app to XSS and injection attacks.
NEVER use "windows": ["*"] with broad permissions -- this grants all windows identical access. ALWAYS use specific window labels.
NEVER set dangerousDisableAssetCspModification: true unless you fully understand that it removes automatic CSP nonce injection for asset loading.
NEVER grant shell:default without scope restrictions -- this allows arbitrary command execution. ALWAYS define explicit command scopes.
ALWAYS enable freezePrototype: true in production -- it prevents JavaScript prototype pollution attacks.
ALWAYS add capabilities for every plugin you install -- plugins do NOT automatically receive permissions.
ALWAYS define deny rules for sensitive paths (e.g., $HOME/.ssh/*) when granting filesystem access.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-impl-security is a skill published in the GitHub repository OpenAEC-Foundation/OpenAEC-Workspace-Composer (5 stars, last pushed 5mo ago), licensed MIT. It adds 97 tokens to every session and 2,502 once invoked, about $0.0005 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.
