## Changes things (16)

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

### `compare_beliefs`

- The name "compare_beliefs" says "compare": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Compare two cited investment cases for support, contradiction or dependency, including explicit unknown and unrelated outcomes. Optional comparison_focus selects a public research topic within both complete cases; the result applies to that topic only. Shared-source provenance does not establish research independence. Per-call x402 price: 0.50 USDC on Base.
```

### `evaluate_belief_scenario`

- The name "evaluate_belief_scenario" says "evaluate": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Apply up to eight hypothetical condition assumptions to a case's recorded scenario model. Does not alter evidence or predict the investor's response. Per-call x402 price: 0.02 USDC on Base.
```

### `get_author_track_record`

- The name "get_author_track_record" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read an investor's stored publication-based outcome cohorts over one explicit ticker, entity, Belief or released corpus scope and optional source/publication window. Includes losses, pending and ineligible counts, preserves action/price/horizon cohorts and verified exits. Historical source completeness remains unknown. This read buys no new market data. Narrow scopes exceeding the supported bound. Per-call x402 price: 0.02 USDC on Base.
```

### `get_belief`

- The name "get_belief" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read a requested complete investment case or evidence beyond a brief, with risks, conditions and coverage gaps. An ordinary library overview can use get_brief without opening each case. Use paragraph_index only when it appears in the returned investment_case; follow support/text offsets. Records without investment_case return their full claims and citations without paragraph selectors. Per-call x402 price: 0.02 USDC on Base.
```

### `get_belief_catalysts`

- The name "get_belief_catalysts" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read evidence-linked Catalyst objects with qualified current status or explicit unknowns. Filter one ticker, entity, Belief or released corpus by person, source, publication dates or status. Current briefs include pending and unassessed attached catalysts; met, missed and superseded records remain available here. Follow signed pagination with identical filters. Per-call x402 price: 0.02 USDC on Base.
```

### `get_belief_changes`

- The name "get_belief_changes" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read a mixed, ordered change journal: author-view revisions, distribution changes and calculated publication outcomes are separate domains with distinct clocks. Use belief_id for changes to one case and inspect each event's domain. Use get_brief for a current synthesis; continuation is for requested journal history or polling. Per-call x402 price: 0.02 USDC on Base.
```

### `get_belief_relationships`

- The name "get_belief_relationships" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Inspect cited relationship paths within one investment case. Preserves stated links, engine inferences and unknowns. Per-call x402 price: 0.02 USDC on Base.
```

### `get_belief_risks`

- The name "get_belief_risks" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read evidence-linked Risk objects for exactly one ticker, entity, Belief or explicit released corpus. Filter by person, source, publication dates, status or severity. Unknown assessments remain unknown; an empty high-severity filter does not prove no material risks. Current briefs include attached open risks, continuing materialized risks and separately marked unknown concerns; no implicit age or severity cutoff. Follow signed pagination with identical filters. Per-call x402 price: 0.02 USDC on Base.
```

### `get_beliefs`

- The name "get_beliefs" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
List dated investment ideas for a requested inventory or filtered research on one ticker or subject. Investor, direction and time filters are optional. An ordinary overview uses get_brief; listing the same research afterward is unnecessary unless the user needs additional cases. Per-call x402 price: 0.02 USDC on Base.
```

### `get_brief`

- The name "get_brief" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use detail=current for a small typed view: up to three current Beliefs, each with up to three attached risks and three pending or unassessed catalysts, evidence URLs, timestamps, material qualifications and explicit unknowns. Open risks and materialized risks with supported continuing relevance qualify; no implicit severity or age cutoff. Selection reserves opposing views then distinct stances and recency. The 16 KiB response reports whole-case omissions, quality gaps and pagination; it is not complete coverage. Overview answers broader company/ETF research with outlook and changes. Full opens machine export. Historical reads preserve their cutoff. Per-call x402 price: 0.02 USDC on Base.
```

### `get_context_assessment`

- The name "get_context_assessment" says "get": a word for reading.
- The description's first verb is "open": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Open a dated engine context assessment and its permitted evidence. Engine analysis is separate from an investor's stated view. Per-call x402 price: 0.02 USDC on Base.
```

### `get_research_visual`

- The name "get_research_visual" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag private-data: The description's first sentence says "read" and "table": it reads databases.

- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read one cited chart or table, including its regions and paginated exact rows or data points. Per-call x402 price: 0.02 USDC on Base.
