## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `fde_catalogue`

- 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
FREE. List every Forward Deployed Engineering rule, playbook, and checklist phase available from this server — id, title, phase, and tags, with the paid body withheld. Call this first to see what is on offer before paying for anything.
```

### `fde_lessons_full`

- 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
PAID. Return the full Forward Deployed Engineering ruleset, or the subset matching a topic. Requires a machine payment (MPP over Stripe). If unpaid, returns the exact payment challenge and the URL to retry against.
```

### `fde_playbook`

- 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
PAID. Return situational runbooks with ordered, checkable steps — DNS migration and static-site change. Use before executing that class of operation, not after it fails.
```

### `fde_preship_checklist`

- 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
PAID. Return the pre-ship checklist: every gate to clear before shipping, each with the concrete failure it prevents. Designed to be called before every deploy.
```

### `pricing_changes`

- 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
PAID. Return only the dated Agent Pricing Index corrections at or after a given date — what changed, not the full 47-row dataset. Backed by a monthly re-read against each vendor's own page. Cheaper than fde equivalent full-dataset calls when you only need to know what moved.
```

## Only reads (1)

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

### `fde_lessons_preview`

- The name "fde_lessons_preview" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
FREE. Return the foundational Forward Deployed Engineering rules in full, no payment required. Each rule carries the real incident behind it and an implementable agent-behavior constraint.
```
