## Findings

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

```untrusted-server-text
The server marks "atlas_links" 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 "atlas_links" says "link": a word for a change.
```

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

```untrusted-server-text
The server marks "atlas_navigate" 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 "atlas_navigate" says "navigate": a word for a change.
```


## Changes things (2)

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

### `atlas_links`

- The name "atlas_links" says "link": 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
List where one Atlas Node references other entries (outbound) and where they reference it (inbound), outbound first. Use to find related entries or what points at this one. Each occurrence gives direction, class, source Section, and the far end's Hook (one-line summary), plus its id and title unless the class is 'undisclosed' (unpublished and unannounced). Results are paged: follow the cursor to the end before concluding nothing points here. An unknown or Roadmap-only (unpublished) subject is refused as invalid_argument.
```

### `atlas_navigate`

- The name "atlas_navigate" says "navigate": 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
Browse the whole Atlas in the publisher's order: the canonical tree of every published Node, or the guided first learning path, an introduction then steps each naming a Node id with narration. Use to survey what exists or to start learning with no topic in mind. Neither view carries entry text or claims; the tour is null if none is published.
```

## Only reads (3)

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

### `atlas_cards`

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

Description, as the server wrote it:

```untrusted-server-text
Get one summary Card per Atlas Node id: its Hook (one-line summary) and the publisher's claims (thesis, law, when-to-reach, or claim), each citing its source Sections. Use when you hold ids and want their guidance without full text, such as to compare entries. Cards return in request order. Atomic: one unknown or Roadmap-only (unpublished) id refuses the whole batch as batch_not_atomic, naming the rejected ids.
```

### `atlas_orient`

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

Description, as the server wrote it:

```untrusted-server-text
Find Atlas entries by topic when you hold no id; an id you already hold can be read directly. Searches Nodes (patterns, concepts, examples) and Roadmap entries (announced, unpublished); kind narrows it to one Node kind, Decisions, or glossary terms. Node discovery preserves leading lexical matches and adds related entries with task vocabulary, using references in either direction. Related candidates explain their connection; direct matches have no via. Empty listings and exact id/title lookups stay lexical. Returns ranked ids with Hooks (one-line summaries; a term's is its whole definition), paged with a cursor. A miss is an empty page; invalid arguments are refused as invalid_argument.
```

### `atlas_read`

- The name "atlas_read" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the full text at one exact Atlas address. A bare Node id returns the whole entry: identity, tree position, Hook (one-line summary), and every Section; relationship occurrences are omitted. A Section, Decision, or glossary term address returns that one item. Use when a summary is not enough or you need exact wording to cite. An unknown or malformed address is refused as invalid_argument; a wrong slug's refusal lists the real ones.
```
