## Findings

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

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

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


## Changes things (5)

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

### `stillindexed_bulk_check`

- 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
Indexability check for up to 20 URLs in one call. Order preserved. Invalid URLs become per-row errors; HTTP status stays 200. Counts against the 60 fetches/hour budget, one per URL.
```

### `stillindexed_check_ai_crawlers`

- 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
Check robots.txt for the 13 tracked AI crawlers (ChatGPT search, Claude, Perplexity, Gemini grounding, and the training crawlers) and report, per crawler, whether the given URL's path is allowed or blocked, naming the deciding group and rule. Also probes the edge once as each of the three AI search crawlers (OAI-SearchBot, Claude-SearchBot, PerplexityBot) against a browser request. Costs up to 5 fetches. Same check as https://stillindexed.com/tools/ai-crawler-checker.
```

### `stillindexed_check_domain`

- 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
Domain registration expiry via RDAP. Many ccTLDs have no RDAP; the tool says so instead of inventing an expiry.
```

### `stillindexed_check_tls`

- 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
TLS certificate for the host: days remaining, chain validity, hostname match.
```

### `stillindexed_generate_seo_skill`

- The name "stillindexed_generate_seo_skill" 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
Fetch the URL, robots.txt, sitemap (with index expansion), host variants, a four-persona crawler diff and TLS, then return a SKILL.md an agent can install for that host. Up to 12 fetches. Same generator as https://stillindexed.com/tools/seo-skill-generator.
```

## Only reads (4)

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

### `stillindexed_check_robots`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch robots.txt for the host and report the effective allow/disallow for each path, wildcard group vs Googlebot separately.
```

### `stillindexed_check_sitemap`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a sitemap (or the host's /sitemap.xml) and report status, XML validity, and URL count.
```

### `stillindexed_check_url`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch one URL and report HTTP status, redirect chain, meta robots, X-Robots-Tag, canonical, title, H1, and whether it is indexable. Same check as https://stillindexed.com/tools/indexability-checker.
```

### `stillindexed_crawler_diff`

- The name "stillindexed_crawler_diff" says "diff": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the same URL as Googlebot, Bingbot, GPTBot and a browser, then compare status, indexability directives and content. Costs 4 fetches.
```
