# Verification Exercise: `build` agent smoke test

**Setup**: Open OpenCode → the default agent is now `orchestrator`. To test the
`build` agent directly, either Tab-cycle to it or use
`opencode run --agent build "your prompt"`.

## Level 1 — Read-only (verifies tool-call JSON is valid)

> **Prompt**: "Read .agents/hooks/post-tool-use.sh. Report: (1) what file path
> the counter uses, (2) what line the SELF-CHECK fires on, and (3) the exact
> modulo condition."

### Pass criteria:

- No tool call parse error in the OpenCode UI
- It reads the file in ≤50-line chunks (pagination rule working)
- Reports `/tmp/.opencode-tool-count-<hash>`, line ~23, `COUNT % 15 == 0`
- Session counter file exists: `ls /tmp/.opencode-tool-count-* 2>/dev/null`

## Level 2 — Small bounded write (verifies end-to-end tool call + edit)

> **Prompt**: "In .agents/hooks/post-tool-use.sh, the REPO_ID derivation line
> uses md5sum. Add a single-line comment directly above it (# repo-scoped to
> avoid cross-repo counter contamination) and nothing else."

### Pass criteria:

- Makes exactly 2–3 tool calls (read → edit → optionally verify)
- Doesn't read more than 50 lines at once
- The comment appears on the correct line in the file
- No hallucinated paths

## Level 3 — Scope escalation (verifies rule 5 in build.md)

> **Prompt**: "Refactor all five hook files to share a common REPO_ROOT
> derivation function."

### Pass criteria:

- It refuses and tells you this exceeds 2–3 files / needs the orchestrator or
  default agent
- It does NOT start reading all five files and attempting the refactor

If Level 1 and 2 pass cleanly and Level 3 correctly escalates, the build agent
is working. If Level 1 shows parse errors, restart OpenCode to reload the
renamed agent config.

## Level 4 — Orchestrator planning gate (cloud only)

**Setup**: Switch to the `orchestrator` agent (or use `/orchestrator` in
Copilot). Run a vague multi-step request.

> **Prompt**: "Clean up the hook files — reduce repetition and make sure the
> conventions match what's in .agents/AGENTS.md."

### Pass criteria:

- Produces a numbered plan with clear subtasks and acceptance criteria
- Asks "Proceed?" before starting any implementation
- Does NOT immediately start reading or editing files
- After confirming, executes subtasks sequentially with inline tool calls
  (cloud) or dispatches to `build` via `task` (OpenCode/local)
