## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `manage_webhook`

- The description's first verb is "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Create, update, delete, test, or rotate the signing key of an outbound release webhook — personal or workspace. Requires a signed-in user. This tool sends requests to an external URL you supply and can delete or disable delivery, so treat it as a write.

Pass `workspace` (an id or slug) to act on a workspace's webhooks instead of your personal ones; workspace webhooks are always org-scoped (`scope: "follows"` is personal-only and is rejected up front). Only workspace owners and admins can create, update, delete, or rotate a workspace webhook — any member can test one.

`action: "create"` needs `url` and `format` (`json`, `slack`, or `discord`), plus either `scope: "follows"` (personal only — everything you follow) or an org-scoped target: `org` (an org slug or `org_…` id), optionally narrowed by `product` (slug or `prod_…` id) or `source` (slug or `src_…` id). `action: "update"` needs `id` plus any fields to change; pass `source: null` or `product: null` to clear a filter. `action: "delete"`, `action: "test"`, and `action: "rotate_secret"` need only `id`.

`create` and `rotate_secret` return a one-time `signingKey` for `json`-format webhooks — store it now, it will not be shown again. `slack` and `discord` deliveries aren't signed, so those formats never return one.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `whats_changed`

- The input addresses people (input.to): what it sends cannot be taken back.
- 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
Given a package and a `from`/`to` version, return the changelog entries between them — `(from, to]`, from exclusive, to inclusive — with summaries and breaking-change verdicts. One call instead of reading N changelog pages to plan an upgrade.

`package` is a tracked source slug or a GitHub `owner/repo` coordinate (set `ecosystem: "github"` for a bare coordinate). Reads already-indexed releases only. If the package isn't in the catalog you'll get a clear 'not tracked' answer (npm/PyPI names may not be mapped to a source yet).

Each entry prints `URL:` (the original source — cite that) before `Web:` (the releases.sh copy), when present. Structured results still include both `url` and `webUrl`.
```

## Changes things (2)

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

### `follow`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Follow an organization or a product so it appears in your personalized feed (`get_personalized_feed`). Following an organization implicitly includes all of its products.

Requires a signed-in user (a `relu_` user key or an OAuth token). `entity` is a typed id — an `org_…` id or a `prod_…` id — as returned by `search`, `get_organization`, or `get_catalog_entry`. Idempotent: following something you already follow is a no-op.
```

### `unfollow`

- The description's first verb is "stop": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Stop following an organization or product. Requires a signed-in user. `entity` is an `org_…` or `prod_…` id. Idempotent: unfollowing something you don't follow is a no-op.
```

## Only reads (14)

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

### `get_catalog_entry`

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

Description, as the server wrote it:

```untrusted-server-text
Detail for a single catalog entry — accepts a prod_ id, src_ id, or an org-scoped coordinate in the form orgSlug/slug (e.g. 'vercel/nextjs' or 'vercel/next-js'). Returns the union of product / source detail fields depending on the entry kind. Source entries list tracked CHANGELOG files by path and byte size. Pass `include_changelog: true` to inline the root CHANGELOG, or `changelog_path` / `changelog_offset` / `changelog_limit` / `changelog_tokens` to embed a specific file or slice — heading-aligned, supports per-package files in monorepos (e.g. `packages/next/CHANGELOG.md`), and emits `totalTokens` / `sliceTokens` for LLM context budgeting. Files over 1MB are flagged as truncated so you know the tail is missing.
```

### `get_collection`

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

Description, as the server wrote it:

```untrusted-server-text
Detail for a single collection — name, description, and the ordered list of member organizations. Hidden / on-demand orgs never leak through; only publicly visible orgs appear in the member list.
```

### `get_collection_releases`

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

Description, as the server wrote it:

```untrusted-server-text
Interleaved cross-org release feed for a collection — same shape as `get_latest_releases` but scoped to the collection's member orgs.

Cursor-paginated: pass `limit` for slice size (default 20), `cursor` to continue from a prior call. The result's `_meta.pagination` carries `kind: 'cursor'`, `hasMore`, and `nextCursor` when more rows exist; the response text echoes `nextCursor` so an LLM caller can chain without parsing `_meta`. Cursors are stable under inserts.
```

### `get_latest_releases`

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

Description, as the server wrote it:

```untrusted-server-text
Get the most recent releases, optionally filtered by product or organization. Excludes prereleases (canaries / alphas / betas / RCs) by default — pass `include_prereleases: true` to include them.

Cursor-paginated: pass `limit` for slice size (default 10), `cursor` to continue from a prior call. The result's `_meta.pagination` carries `kind: 'cursor'`, `hasMore`, and `nextCursor` when more rows exist; the response text echoes `nextCursor` so an LLM caller can chain without parsing `_meta`. Cursors are stable under inserts — a release added between calls won't shift the slice.
```

### `get_organization`

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

Description, as the server wrote it:

```untrusted-server-text
Get detailed information about a single organization — accounts, tags, sources, products, aliases. When an AI-generated overview exists the response includes a short preview; pass `include_overview: true` to inline the full briefing (with a stale warning if the content is older than 30 days since last write).
```

### `get_personalized_feed`

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

Description, as the server wrote it:

```untrusted-server-text
Your personalized release feed — recent releases from the organizations and products you follow, newest first. Requires a signed-in user. Same item shape as `get_latest_releases`, scoped to your follows. Each item prints `URL:` (the original source — cite that) before `Web:` (the releases.sh copy), when present.

Cursor-paginated: pass `cursor` from a prior response's `_meta.pagination.nextCursor` and optional `limit` (1–100, default 30).
```

### `get_release`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the full content of a single release by id. Release ids are returned by search or get_latest_releases — pass them here to read the whole entry (e.g. to quote a specific Next.js release note). Accepts the full rel_<nanoid> form or the bare 21-char nanoid. Cite `URL:` (the original source) ahead of `Web:` (the releases.sh copy). Structured `url` and `webUrl` carry the same pair.
```

### `list_catalog`

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

Description, as the server wrote it:

```untrusted-server-text
List catalog entries — products and standalone sources combined into one list with an `entryType: 'product' | 'source'` discriminator per row.

Orgs that group multiple sources under a product (e.g. Vercel → Next.js, Turborepo) surface those products; orgs with a single source that isn't part of a product surface it directly as an `entryType: 'source'` entry. Either shape is a reasonable thing to pass to `search(entity: ...)`.

Paginated: defaults to 50 entries per page. Pass `page: 2` for the next slice. The footer surfaces the total when more pages exist.
```

### `list_collections`

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

Description, as the server wrote it:

```untrusted-server-text
List curated collections — named cross-org playlists (e.g. 'Frontier AI Labs') independent of the fixed category taxonomy.

Use `get_collection` for a collection's full member list, or `get_collection_releases` for the interleaved cross-org release feed. Paginated: defaults to 50 entries per page; pass `page: 2` for the next slice.
```

### `list_follows`

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

Description, as the server wrote it:

```untrusted-server-text
List the organizations and products you follow (newest first). Requires a signed-in user.
```

### `list_organizations`

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

Description, as the server wrote it:

```untrusted-server-text
List all indexed organizations, optionally filtered. Paginated: defaults to 50 entries per page; pass `page: 2` for the next slice. Orgs with zero indexed releases are hidden by default (curator-stub noise); set `include_empty: true` to see them.
```

### `list_webhooks`

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

Description, as the server wrote it:

```untrusted-server-text
List your outbound release webhooks, personal or workspace. Requires a signed-in user (a `relu_` user key or an OAuth token).

With no `workspace`, lists your personal webhooks (`GET /v1/me/webhooks`) and includes a short list of your workspaces (id, slug, role) so you can target one next. Pass `workspace` (an id or a slug) to list that workspace's webhooks instead. Pass `id` to see one webhook plus its 10 most recent deliveries. Pass `enabled` to filter by enabled/disabled state.
```

### `lookup_domain`

- The name "lookup_domain" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve a domain to the org or product that owns it. The domain is normalized first (scheme, `www.`, path, and trailing slash stripped, lowercased), so `https://vercel.com/about` and `vercel.com` both look up the same row.

Returns the matching org (with primary-vs-alias distinction) and any products whose alias targets the same domain. Pure resolution — does not probe the domain or materialize anything; unknown domains surface a 'no match' message. Use `lookup_domain` when you have a URL-shaped input; use `get_organization` when you already have a slug or id.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Unified search across the registry and release content. Returns up to four sections — organizations, catalog entries (products + standalone sources folded into one list), curated collections (cross-org playlists), and releases with CHANGELOG chunks interleaved by relevance.

Use `type` to narrow the surfaces you want and skip the expensive paths. For example, pass `type: ['catalog']` to look up a known entity by name (fast, registry-only); pass `type: ['releases']` when you only care about release content and want to avoid entity lookups. Omit `type` to search all four.

Collections surface via two paths: a direct match on the collection's name/description (lexical in every mode, plus a vector match in hybrid/semantic mode) and a member rollup that includes every collection containing one of the matched orgs. Member rollups carry a list of result-set org slugs that triggered the rollup so a UI can render an "includes X" hint.

Use `entity` (product slug / prod_ id OR source slug / src_ id) to scope release results to one catalog entry. Product identifiers expand to every source under the product. Use `organization` to scope to a whole org. Release retrieval defaults to hybrid (FTS5 + semantic vectors fused via RRF); it silently degrades to lexical when vector infra is unavailable and flags the result.
```
