+# `_graders` — shared waza grader helpers
+
+Reusable `program`-grader scripts that any task can reference.
+
+## `verify-code-runs.ts` — does the produced code actually run?
+
+Closes the "does the artifact run" gap from OpenAI's
+[skill-eval methodology](https://developers.openai.com/blog/eval-skills): for
+*building* skills, grading the response text for the right patterns isn't enough
+— the code the agent produces should actually parse/type-check.
+
+```yaml
+graders:
+  - type: program
+    name: produced_code_parses
+    config:
+      command: "bun"
+      args: ["evals/_graders/verify-code-runs.ts"]
+      timeout: 60
+```
+
+### How it works
+
+waza pipes the agent's full final response to a `program` grader on **stdin**
+(exit 0 = pass, non-zero = fail). This helper:
+
+1. Extracts fenced code blocks from the response.
+2. Writes JS/TS blocks to temp files.
+3. Syntax-checks JS with `node --check`; type-checks TS with
+   `npx tsc --noEmit --skipLibCheck` (only fails on `TS1xxx` *syntax* errors, so
+   missing-import noise in a snippet doesn't false-fail).
+4. Exits 0 only if every code block parses; 1 otherwise (including "no code
+   block found", which is itself a failure for a code-producing task).
+
+### waza `program` grader facts (learned the hard way)
+
+- The agent's response arrives on **stdin** — not as workspace files. The
+  copilot agent-under-test answers in text and does **not** populate
+  `$WAZA_WORKSPACE_DIR` by default.
+- waza **swallows grader stderr on success** and only surfaces it on failure.
+  Exit non-zero (temporarily) if you need to see a grader's diagnostics.
+- Reference a committed script via a single clean `args` entry rather than
+  inlining bash — inline shell/YAML escaping is brittle (same lesson as the
+  `_hooks/` helpers).

+# `_hooks` — shared waza `before_run` helpers
+
+## `prepare-skill.ts`
+
+Syncs a skill into `~/.agents/skills/<name>/` (where the copilot agent discovers
+skills) and runs `npm install` if the skill ships bundled scripts.
+
+```yaml
+hooks:
+  before_run:
+    - command: "bun evals/_hooks/prepare-skill.ts <skill-name>"
+```
+
+### Two gotchas this helper exists to handle
+
+1. **waza runs hook `command:` entries WITHOUT a shell.** `cd X && cmd` fails with
+   `cd: executable file not found in $PATH`. Each hook must be a single executable
+   invocation — no `&&`, no shell builtins. This helper does the multi-step work
+   (mkdir + rsync + npm install) in one process.
+
+2. **Hooks run from waza's invocation cwd (the repo root), not the eval dir.** So the
+   path is `evals/_hooks/prepare-skill.ts`, not `../_hooks/...`. The helper itself
+   resolves the repo root from its own file location, so it's robust regardless.
+
+## Running evals against OpenRouter
+
+waza's embedded GitHub Copilot CLI has native BYOK custom-provider support, and
+OpenRouter is OpenAI-compatible — so waza runs on OpenRouter with **zero adapter
+code**. Set these env vars before `waza run` (the skillet `skill-eval` skill's
+`run-waza.ts` sets them automatically):
+
+```
+COPILOT_PROVIDER_TYPE=openai
+COPILOT_PROVIDER_BASE_URL=https://openrouter.ai/api/v1
+COPILOT_PROVIDER_WIRE_API=completions          # NOT "openai" — waza rejects that
+COPILOT_PROVIDER_API_KEY=$OPENROUTER_API_KEY
+COPILOT_MODEL=anthropic/claude-opus-4.8        # BYOK refuses to start without an explicit model
+COPILOT_DISABLE_KEYTARCLI=1
+```
+
+Model slugs must be real OpenRouter IDs (family-first, e.g. `anthropic/claude-opus-4.8`).
