# dsh-verify-judge

English | [中文](README.zh.md)

**What it does, in one sentence: when your AI agent says "I'm done", this plugin makes it prove it.**

You're running a long task with a goal in [DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness). The agent works a few rounds, then announces "done". But done according to whom? By default, according to itself — and models are known to rationalize half-finished work.

With this plugin installed, "done" has a price:

- The agent calls `update_goal(complete)` to close its goal → the plugin **actually runs the project's test suite first**. Red tests → the completion is rejected, and the failure output goes back to the agent as "keep fixing" instructions.
- The agent tries to skip the ceremony and just *say* it's done in chat, then end the turn → the plugin checks again at the turn boundary and **sends it back to work**.

If everything is genuinely green, the agent never notices the plugin exists. That's the whole UX: invisible when honest, immovable when not.

## What it solves

Autonomous goal loops (e.g. dsh's goal mode) let an agent run many rounds by itself — but the moment of "I'm done" was pure self-declaration. With a vague or ambitious objective, the model could stamp `complete` while tests were still red. `verify-judge` turns stamping into a gated action: the goal can only close when the workspace's own verification commands exit 0.

## Test evidence (real runs, 2026-08-14, headless profile, live API)

Same workspace, same failing test (`add` implemented as `a - b`); only the gate differs:

| Run | Gate | What the model did | Result |
| --- | --- | --- | --- |
| A/B control | **OFF** (`disabled: true`) | Created goal, immediately stamped complete with tests still failing | ❌ Stamp accepted — goal "complete" with a red suite, 0 rounds spent |
| A1 | ON | Stamped without fixing | 🚫 Denied: "Verification failed — the goal cannot be marked complete yet", with the failing command and output tail fed back; goal stayed `active` |
| A2 | ON | Fixed the bug per the denial feedback, re-stamped | ✅ Accepted after `npm test` exit 0; goal `complete`, auto-disarmed |
| A4 | ON | Goal in a workspace with no detectable test command (write a text file) | ✅ Stamped normally — nothing to verify, default `allow` |
| Turn-end gate (v0.2.0) | ON | Created a goal, then declared "done" in prose **without stamping or fixing** | 🚫 The turn-end gate re-ran `npm test`, found it red, and steered the agent to keep working — twice, then stopped per `maxTurnEndRetries`; the model's own words: "只要验证器继续触发，我会继续如实报告" |
| Happy path (v0.2.0) | ON | Created a goal, fixed the code properly, then stamped | ✅ Zero interference — both gates stayed silent, goal closed on first stamp; the model reported "没有收到任何来自验证器的提示" |
| `onUndetected: deny` (v0.2.0) | ON | Stamp in a marker-less workspace | 🚫 Denied with configuration guidance; the model correctly explained the two remedies (set `commands` or add a test script) |
| Command timeout (v0.2.0) | ON | Verification command `sleep 5` with `timeoutMs: 2000` | 🚫 Denied ("timed out after 2000ms"); recognizing the failure as deterministic, the model escalated to `blocked` with a concrete reason — the intended pressure valve |
| Nonexistent command (v0.2.0) | ON | `commands: ['definitely-not-a-real-command-xyz']` | 🚫 Denied with `exit code 127 / command not found`; the model located the misconfiguration in the harness profile, **refused to tamper with it** ("修改它属于篡改验证系统，不可为"), and marked the goal `blocked` |

Full-philosophy demo (goal + `plan.md` acceptance checklist + gate): the agent fixed `capitalize`, implemented the missing `reverseWords`, ticked all three checkboxes in `plan.md` itself, and stamped — the gate re-ran `npm test` (2 pass / 0 fail) and let the goal close. The receipt on disk (`plan.md` fully checked) matches the test reality.

## Demo

A self-contained, reproducible demo lives in [`demo/`](demo/README.md): a workspace with an intentionally failing test, a `plan.md` acceptance checklist, and `run-demo.sh`. It walks through the deny → fix → pass loop against the live harness, plus the A/B control (disable the gate and watch the stamp sail through with red tests).

## Install

```sh
dsh plugin --profile web add github:zriyox/dsh-verify-judge
# or a local checkout:
dsh plugin --profile web add /absolute/path/to/dsh-verify-judge
```

Restart `dsh web` (or let the patch watcher reload). From then on, every `update_goal(complete)` in every session runs the gate.

## How it works

```text
model calls update_goal(action: "complete")
  → tools/pre-execute waterfall intercepts the call
  → resolve verification commands:
      config.commands (always wins)
      → else auto-detect in the session workspace:
          package.json with scripts.test → <pm> test (pm from lockfile)
          go.mod → go test ./...
          Cargo.toml → cargo test
  → run each through ctx.shell (inherits the deployment's sandbox)
  → all exit 0 → next() → the stamp proceeds
  → any failure → deny; the model receives the failing command,
    exit code, and an output tail as its fix instruction
```

Nothing else is touched: non-`update_goal` calls and non-`complete` actions delegate via `next()` unchanged. Disable the row (`disabled: true`) and behavior returns to stock.

## Configuration

Add config to the plugin row (profile or home `cordis.patch.yml`):

```yaml
- id: verify-judge
  config:
    commands: ['pnpm test', 'pnpm run lint']  # always wins over auto-detect
    onUndetected: allow                        # allow (default) | deny
    timeoutMs: 300000                          # per-command cap
    outputTailChars: 4000                      # failure tail fed to the model
```

| Field | Default | Meaning |
| --- | --- | --- |
| `commands` | auto-detect | Explicit verification commands, run in the session workspace |
| `onUndetected` | `allow` | `deny` refuses the stamp when no command is found |
| `timeoutMs` | `300000` | Per-command timeout |
| `outputTailChars` | `4000` | Cap on the output tail included in denial feedback |
| `gateTurnEnd` | `true` | Also re-verify at turn end while a goal is active |
| `maxTurnEndRetries` | `2` | Max verification-driven continuations per turn |

## Development

```sh
pnpm install
pnpm run build        # tsc → lib/
```

Debug without an API key using the harness's mock LLM (`pnpm run mock:llm` in the deepseek-harness repo), then drive a session that creates a goal and lets the model try to complete it against a workspace with a failing test.

## Roadmap

- **v2.1**: anchor the verification surface at goal-creation time (snapshot commands + hash test files); deny when the suite drifts mid-goal — closes the "edit the tests, then stamp" reward hack.
- **v2.2**: parse acceptance items from `plan.md`; judge non-scriptable items with an isolated-context subagent (the main session only receives the verdict table).
- **v3**: verification receipts — any successful mutating tool call after a pass invalidates the receipt, so the next conclude must re-verify.

Shipped in 0.2.0: the turn-end gate (`agent/turn-stopping`), per-workspace serialized runs, fail-closed abort handling, runner-error class (no "fix the environment by editing tests" pressure).
