+
+# LibreQoS Review Sub-Agents Workflow
+
+Use this skill when code changes in this repo need the project-standard reviewer pass.
+
+## Agents
+
+- `thomas`: adversarial review of recent code changes for Rust best practices, safety, idiomatic style, and warning or Clippy suppression
+- `beck`: review of recent code changes for meaningful unit-test coverage and weak or pointless tests
+- `jonas`: review of recent code changes for scope drift, unrelated cleanup, and algorithmic or performance mistakes
+- `helen`: review of recent user-interface changes for accessibility, ADA issues, missing alt text, missing labels, missing ARIA semantics, and related barriers
+
+## Required Invocation Rules
+
+- During large sessions, invoke `thomas`, `beck`, and `jonas` together after substantial implementation batches.
+- Always invoke `thomas`, `beck`, and `jonas` before the final user-facing completion message when code changed in the session.
+- After any user-interface change, invoke `helen`.
+- If the session includes both UI and code changes, invoke `helen` alongside the others at the same review checkpoint.
+
+## What Counts As A Large Session
+
+Treat a session as large when any of these are true:
+
+- the diff is more than a tiny one-file tweak
+- multiple files or crates changed
+- you finished a meaningful implementation batch and are about to continue layering on more work
+- the blast radius is not obvious from a quick glance
+
+## Invocation Pattern
+
+1. After a substantial implementation batch, spawn `thomas`, `beck`, and `jonas` in parallel against the current recent changes.
+2. If UI changed, spawn `helen` at the same checkpoint.
+3. Use the current worktree diff as the default scope. If the worktree is clean but the session included recent commits, pass an explicit commit or diff range.
+4. Review the findings, fix valid issues, or record why a concern is intentionally accepted.
+5. Before final completion, rerun any reviewer whose scope changed since the prior pass.
+
+## Required Prompt Shape
+
+When spawning a reviewer, include:
+
+- the review scope:
+  - current worktree diff, or
+  - explicit commit or diff range
+- the intent of the change
+- any area-specific context that helps the reviewer load the right project skills
+
+Example prompt for `thomas`, `beck`, and `jonas`:
+
+```text
+Review the recent changes for this session. Use the current worktree diff as the review scope unless I specify a narrower range. The goal of the change is: <brief intent>.
+```
+
+Example prompt for `helen`:
+
+```text
+Review the recent user-interface changes for this session. Use the current worktree diff as the review scope unless I specify a narrower range. Focus on accessibility and other user barriers.
+```
+
+## Notes
+
+- These agents are read-only review surfaces, not replacements for targeted tests, `cargo check`, `cargo clippy`, or visual verification.
+- For tiny trivial edits, an intermediate review pass may be unnecessary, but the final required review still applies whenever code changed.
+- In this repo, the subagent definitions live under `.codex/agents/*.toml`.

 ## Preferred Rust Direction

@@ -42,4 +44,9 @@ Use this skill for Rust work in this repo.
 - Existing code does not fully match all preferred conventions yet. Treat these as direction for new and touched code, not as a reason to perform unrelated cleanup.
 - Build/package scripts live under `src/`, not repo root.
 - `src/build_dpkg.sh` is a functional packaging manifest for shipped installs. Forgetting to update it is a common failure mode; treat package-content drift as a bug.
- For Insight/LTS2 integrations, preserve the existing external protocol and identity values unless the task explicitly covers coordinated changes on both sides. Unilateral protocol drift is a breaking change.
+- Treat protocol and identity surfaces as compatibility boundaries:
+  - Prefer additive-only changes (new optional fields, `#[serde(default)]` where applicable).
+  - Assume rolling upgrades where old/new binaries may coexist unless a coordinated restart is explicitly planned.
+  - Do not rename fields, change types, or change semantics without explicit versioning and a coordinated rollout plan.
+  - Keep compatibility shims at the boundary, make them explicit, and test them; avoid “fallbacks everywhere”.
+  - Avoid per-request `info!` logging in hot paths; prefer `debug!`, sampling, or aggregate counters.
