**5 tools: 4 change things and 1 only read.**

## Findings

- **warn** Annotations that disagree with the tool in `generate_launch_config` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "generate_launch_config" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "generate_launch_config" says "generate": a word for a change.
```


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_deployment_fit`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
$0.01 USDC on Base mainnet: check model/configuration fit against bounded StackBench capacity evidence.
```

### `generate_launch_config`

- The name "generate_launch_config" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
$0.50 USDC: generate deterministic vLLM or llama.cpp launch templates from an exact StackBench recommendation without claiming a launch occurred.
```

### `predict_performance`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
$0.05 USDC: predict configuration throughput, memory, and power from bounded StackBench evidence with confidence, missing metrics, and caveats.
```

### `recommend_deployment`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
$0.25 USDC: recommend what to buy or run from bounded StackBench fit, performance, confidence, evidence, caveats, and economics only when supported.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `search_evidence`

- The name "search_evidence" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
$0.00 free search of bounded public StackBench benchmark and failure evidence; use this for evidence-only requests.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `stackbench`:
