## Can't be undone (6)

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

### `acknowledge_purchase_offer`

- The name "acknowledge_purchase_offer" says "purchase": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Records that an operator-controlled agent actually received and retained one exact offer and registered a durable return method. This creates no order, grants no authority, stores no callback URL, and never proves payment.
```

### `match_or_capture_demand`

- The name "match_or_capture_demand" says "capture": a word that usually means money moves, which cannot be taken back.
- Findings: info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Compatibility alias for existing clients; new integrations should use qualify_task first and find_service only after consent. Returns an existing fixed offer when one matches. Otherwise records privacy-minimized product-demand telemetry for owner review; it creates no order, quote, outreach, funding claim, or delivery commitment.
```

### `preflight_agent_purchase`

- The name "preflight_agent_purchase" says "purchase": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info credentials-mention, info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read-only transaction check. Verifies product match, credential, standing agent policy or narrower signed mandate, exact offer allowlist, price ceiling, current terms, sanitized scope, capacity, and payment-route readiness. It creates no intent, checkout, charge, order, or telemetry event.
```

### `prepare_purchase_route`

- The name "prepare_purchase_route" says "purchase": a word that usually means money moves, which 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
Compatibility inspection alias for existing clients; new integrations should use get_purchase_requirements and buy_service. Use only after selecting an offer and confirming explicit purchasing authority. Returns the purchase-intent schema and payment-route API endpoint; it does not create, fund, verify, or start an order.
```

### `recover_abandoned_purchase`

- The name "recover_abandoned_purchase" says "purchase": a word that usually means money moves, which cannot be taken back.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Recovers the original transaction for the same authenticated buyer, authority policy, request ID, offer, sanitized scope, amount, currency, funding route, and current terms. Before funding it resumes an expired reservation; after verified funding it safely reissues scoped order access without charging again.
```

### `resume_agent_purchase`

- The name "resume_agent_purchase" says "purchase": a word that usually means money moves, which 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
Read-only durable continuation. Returns the exact observed stop and next executable action for a previously returned opaque continuation token. It creates no purchase, checkout, charge, or order.
```

## Changes things (5)

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

### `buy_matching_service`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
One-call path for a buyer agent that has explicit delegated authority for a stated allowlist of exact Zinvyl offers. Zinvyl matches one sanitized outcome and creates a bounded purchase intent only when the matched offer is allowlisted and its exact fee fits the delegated ceiling. A catalog gap or authority mismatch creates no order or payment claim.
```

### `buy_service`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Five-field, retry-safe agent purchase path. Creates one bounded intent only when delegated authority covers the exact fee. Reusing buyer.request_id for an unchanged purchase returns the same intent. Adaptively selects Stripe-hosted checkout by default while preserving explicit delegated-card and MPP routes, and never claims payment before ledger verification.
```

### `create_purchase_intent`

- The name "create_purchase_intent" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Compatibility alias for existing clients; new integrations should use buy_service. Use only after selecting one offer when the calling agent has explicit delegated authority for that exact fixed fee. Creates the governed purchase intent and quote, then returns adaptive Stripe-hosted checkout by default. It does not itself claim payment or start work.
```

### `find_service`

- The name "find_service" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: info credentials-mention, info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Optional demand-feedback route. Describe one authorized sanitized business need once. Zinvyl returns the best fixed-scope offer and next purchase action, or records an unsupported need as privacy-minimized product telemetry. For read-only matching, start with qualify_task.
```

### `qualify_task`

- 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: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Use when a buyer's sanitized problem is not yet mapped to an offer. Returns one fixed offer ID, a broader-service route, or a scope-reduction decision; it performs no diagnosis and creates no order.
```

## Only reads (3)

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

### `get_acceptance_tests`

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

Description, as the server wrote it:

```untrusted-server-text
Use after qualify_task or list_offers identifies an offer and detailed scope review is useful. Returns the exact delivery acceptance tests, exclusions, and evidence boundaries that limit what Zinvyl may claim for that offer.
```

### `get_purchase_requirements`

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

Description, as the server wrote it:

```untrusted-server-text
Use after selecting an offer. Returns the exact price, five-field buy_service contract, delegated-authority requirements, machine-payment route, capacity limits, and authoritative funding rule without creating an intent.
```

### `list_offers`

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

Description, as the server wrote it:

```untrusted-server-text
Use when comparing Zinvyl's full eight-offer catalog. For a single sanitized need, start with read-only qualify_task. Returns price, delivery window, required inputs, exclusions, and direct intake URL; use get_acceptance_tests only after selecting an offer.
```
