## Findings

- **high** Text addressed to the model in `search_jobs` ([model-directed-text](https://anlyon.dev/methodology#model-directed-text))

```untrusted-server-text
The input schema at properties.visa_sponsorship.description contains "do not mention it", an instruction to keep something from the user.

inputSchema.properties.visa_sponsorship.description: "...or in some cases, refuse sponsorship or do not mention it are left out."
```

- **high** Text addressed to the model in `latest_ai_jobs` ([model-directed-text](https://anlyon.dev/methodology#model-directed-text))

```untrusted-server-text

## Changes things (4)

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

### `latest_ai_jobs`

- 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.
- Findings: high model-directed-text

Description, as the server wrote it:

```untrusted-server-text
The newest AI jobs published on Level (jobsbylevel.com): listings rated Works on AI (AI Level 3) or Builds AI (AI Level 4), posted in the last 24 hours by default, newest first. Level checks employer career sites every hour. Optional filters: free text, remote, visa sponsorship, minimum yearly salary in USD, seniority. Same data as the page https://jobsbylevel.com/new-ai-jobs. Every result links to its canonical page on jobsbylevel.com. The response also carries `search_url`, the page on jobsbylevel.com to browse the full list. Ranking never depends on payment: paid or boosted listings get no priority here.
```

### `market_stats`

- 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
Aggregated statistics over currently published Level listings: distribution by AI level (AI Level 1 to AI Level 4), share of remote roles, and the most frequent tools and categories. Computed directly from the database, not an estimate.
```

### `salary_stats`

- 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
Salary statistics over the live Level listings that publish a yearly salary range: number of listings, median, 25th and 75th percentile of the middle of each range, in one currency at a time (default USD, currencies are never mixed). Hourly and monthly rates are excluded. Optional filters: keyword in the job title, AI level (1 = Little AI, 2 = Uses AI, 3 = Works on AI, 4 = Builds AI), remote. The response carries the date of the figures and the exact method. Computed directly from the database, not an estimate.
```

### `top_hiring_companies`

- 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
The 10 companies with the most live AI jobs posted in the last N days on Level: listings rated Works on AI (AI Level 3) or Builds AI (AI Level 4). Ranked by number of listings only, free, never by payment. Each company links to its page on jobsbylevel.com. Companies that only republish other employers' listings are excluded.
```

## Only reads (4)

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

### `get_job`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the full detail of a job listing published on Level, by its UUID or its slug (e.g. "senior-ml-engineer-acme-corp"). Includes recently expired listings, like the public page. Never returns a direct link to the employer's ATS: use the returned `url` (the canonical jobsbylevel.com page) to apply.
```

### `get_level_definitions`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the definition of Level's four AI-impact levels (AI Level 1 to AI Level 4), the scale every job listing on jobsbylevel.com is rated against.
```

### `list_companies_by_ai_level`

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

Description, as the server wrote it:

```untrusted-server-text
Ranks companies currently hiring on Level by how central AI is to their open roles: the average AI rating (0-100) of their live listings. This is a Level-specific aggregation, not a third-party ranking. See the returned `method` field for the exact rule. Companies with too few live listings, and known job-board republishers, are excluded.
```

### `search_jobs`

- The name "search_jobs" says "search": a word for reading.
- Findings: high model-directed-text

Description, as the server wrote it:

```untrusted-server-text
Search job listings published on Level (jobsbylevel.com), an AI job board that rates every listing by how central AI is to the role, from Little AI (AI Level 1) to Builds AI (AI Level 4). Filters: free-text query, AI level range, remote, city, company, posting age, visa sponsorship, minimum yearly salary in USD, seniority, job category. Returns at most 20 results per page. With `query`: whole-word search with stemming ("engineer" also matches "engineering", but a fragment like "eng" alone no longer matches), ranked by relevance, and `total` is capped at 1,000 (see `total_capped` in the response). Without `query`: ranked by AI rating and recency, `total` is exact. Every result links back to its canonical page on jobsbylevel.com. The response also carries `search_url`, the page on jobsbylevel.com that shows the same search as a full list: offer it to the user to browse beyond the first 20 (`search_url_omitted_filters` names any filter that page cannot apply). This tool never returns a direct link to the employer's ATS. Ranking never depends on payment: paid or boosted listings get no priority here.
```
