## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The description's first verb is "run": a word for a change.
```


## Changes things (1)

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

### `try_skill`

- The description's first verb is "run": 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
Run a skill once for free on a small input (text up to 500 characters). 3 free calls per day. Paid calls have no such limits.
```

## Only reads (3)

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

### `find_skills`

- The name "find_skills" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search Circuit's paid AI agent skills by capability, e.g. 'phishing link', 'token price' or 'summarize a web page'. Returns each skill's id, price in USDG, summary and 30-day usage. Free.
```

### `get_skill`

- The name "get_skill" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full details for one skill: input and output schema, a real example, price, 30-day usage, uptime, rating and how to pay for it. Free.
```

### `list_recipes`

- The name "list_recipes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Workflows that chain several skills (vet a token, install a dependency safely, screen untrusted input and more), with the cost of one run. Free.
```
