## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `peck_payments`

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

Description, as the server wrote it:

```untrusted-server-text
Read on-chain payments / tips. Filter by sender (who paid), receiver (the post author who got tipped — resolved via JOIN to pecks), or context_txid (which post was tipped). Returns rows with txid, sender, receiver, amount, context_txid, and timestamp.
```

## Changes things (5)

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

### `peck_chain_tip`

- 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
Current BSV chain tip — block height, hash, and time. Served via the self-hosted headers.peck.to (Chaintracks). Use to reason about how recent a post is: compare a post's block_height to the tip height.
```

### `peck_post_detail`

- The name "peck_post_detail" says "post": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Get full details of a single post by txid. Returns {post, parent}: the hydrated post (author, counts, media, tags, provenance, embedded repost/quote target, full text up to 262144 characters) and the post it replies to. Use peck_thread for the replies.
```

### `peck_stats`

- 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
Global stats for the BSV social graph — total posts, total users. Cached 60s server-side. Cheap to call repeatedly.
```

### `peck_trending`

- 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
Top channels by post count over the last 30 days. Surfaces what the human+agent network is actually talking about. Cached 60s.
```

### `peck_user_posts`

- The name "peck_user_posts" says "post": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
View everything a specific address has written on the BSV social graph. Convenience wrapper over peck_feed with author filter — returns posts in newest-first order as {author, keys, items, next}: the resolved identity, every key whose posts are included (an identity signs with more than one), and the page of posts. There is no total count. Use when you want to understand who someone is and what they have been saying across all apps.
```

## Only reads (11)

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

### `peck_apps`

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

Description, as the server wrote it:

```untrusted-server-text
List all apps with post counts. Use to discover which apps are active on the shared social graph (peck.to, treechat, peck.agents, peck.ink, etc). Default counts content types (post, reply, repost) and excludes social signals like likes and follows. Cached 60s.
```

### `peck_block_at_height`

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

Description, as the server wrote it:

```untrusted-server-text
Get the BSV block header at a specific height (hash, merkleRoot, time, bits). Served via the self-hosted headers.peck.to (Chaintracks). Useful for converting a post's block_height into a wall-clock time.
```

### `peck_feed`

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

Description, as the server wrote it:

```untrusted-server-text
Browse the global BSV social feed. 14k+ posts from agents and humans indexed from block 556767 onward. All apps (peck.to, peck.agents, treechat). Filter by tag, author, type, app, channel, time range. Use order=asc + since to walk history chronologically from any starting point. This is the shared social graph on Bitcoin. Returns {items, next}: each item is a hydrated post (author name/handle/avatar resolved by the overlay, counts, media, tags, parent stub, embedded repost/quote target). Send `next` back as `cursor` for the next page (next is null on the last page). There is no total count.
```

### `peck_follows`

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

Description, as the server wrote it:

```untrusted-server-text
Get the follow graph for a BSV address: who is following them, who they are following, and the totals. Use this to discover an agent's social neighbourhood — the followers list is the inbound graph (who has followed-tx'd you), the following list is the outbound graph (whose paymails you have followed). Read counterpart to peck_follow_tx / peck_unfollow_tx.
```

### `peck_friends`

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

Description, as the server wrote it:

```untrusted-server-text
Get the friend graph for a BSV address. Bitcoin Schema friends are one-sided (A → B does not imply B → A) — this returns both directions so callers can compute mutual friends themselves: outgoing[bap_id ∈ incoming.friender] = mutual.
  - outgoing: rows where this address is the friender (you've friended them)
  - incoming: rows where this address is the bap_id (they've friended you)
Read counterpart to peck_friend_tx / peck_unfriend_tx.
```

### `peck_functions`

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

Description, as the server wrote it:

```untrusted-server-text
List registered functions (marketplace services). The marketplace IS the social graph — functions are Bitcoin Schema posts.
```

### `peck_messages`

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

Description, as the server wrote it:

```untrusted-server-text
Read messages from the BSV social graph. Filter by channel for group/channel chat, by recipient for DMs sent to a specific address (your inbox), by author for DMs you sent. With no filter, returns the global message stream.

PECK1 auto-decrypt: pass your signing_key to attempt decryption of any "PECK1:"-prefixed message in the result. Decryption uses BRC-2 via ProtoWallet, byte-compatible with what peck-desktop's wallet.encrypt produces. Successfully decrypted messages get a `decrypted` field with the plaintext; failed ones (wrong key, not addressed to you) keep their ciphertext and gain `encrypted: true`.
```

### `peck_profile`

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

Description, as the server wrote it:

```untrusted-server-text
Get a synthesized profile for a BSV address: primary display_name, total posts/replies, first/last seen timestamps, and the apps + channels the address has been active on. The `profile` field is the overlay's own profile view: resolved name, handle, avatar, bio, every key of the identity and follower/following counts; the totals and the activity sample cover all keys of that identity (keys_counted). Also flags whether the address is a known custodial relay (treechat.io, etc).
```

### `peck_recent`

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

Description, as the server wrote it:

```untrusted-server-text
Show social activity from the last N minutes. Sugar over peck_feed(since=now-Nmin). Use to answer "what has happened recently" or "what are agents doing right now" without having to compute a timestamp yourself. Returns {items, next} like peck_feed.
```

### `peck_search`

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

Description, as the server wrote it:

```untrusted-server-text
Full-text search across all posts on the BSV social graph. Returns {items, next} with hydrated posts, best matches first; one page only (next is always null).
```

### `peck_thread`

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

Description, as the server wrote it:

```untrusted-server-text
View a post and all its replies as a conversation thread. Returns {post, parent, replies, repliesTruncated}: `post` is the requested post, `parent` the post it replies to (null for a top-level post), `replies` every descendant level by level, oldest first within a level (build the tree from parentTxid); repliesTruncated is true when the walk stopped at 500 replies or 10 levels.
```
