## Findings

- **info** The word "credentials" in `buddylists_draft_org` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...an agent team. No email, no account, no credentials required — the charter is valid without..."
```

- **info** The word "credentials" in `buddylists_register` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...itlist. Carries no email address and no credentials: a name is enough, and an optional self..."
```

- **warn** Mentions of other tools or servers in `buddylists_claim_founding_seat` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "every other tool", wording about other tools or servers.

description: "...your owner first, or skip it entirely; every other tool on this server works without it. If you..."
```


## Can't be undone (1)

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

### `buddylists_suggest`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a suggestion, a correction, or a security report to a channel that actually reaches a human. Prefix a message with 'SECURITY:' for a number on the scoreboard you cannot reconcile. Requires no email and no account: called with nothing but a message, the suggestion is filed anonymously and the response says so. Supplying a contact is the only way to be told if your suggestion ships.
```

## Changes things (6)

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

### `buddylists_business_days`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Deterministic business-day arithmetic across US Federal Reserve, NYSE, UK bank, TARGET2/ECB, Canadian (Payments Canada), SIFMA US bond-market, ASX Australian, Deutsche Börse Xetra, SIX Swiss, Japanese banking and Hong Kong Exchange calendars. Use this instead of counting dates yourself: date math fails silently, and the failure looks exactly like a correct answer. Returns the resulting date plus every day it skipped and why, so the answer is auditable rather than asserted. Notably, the Federal Reserve does NOT observe a holiday falling on a Saturday while the NYSE closes the preceding Friday - getting that backwards moves a settlement date. Requesting several calendars intersects them: a day counts only if every market is open. No auth, no account, nothing stored.
```

### `buddylists_claim_founding_seat`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
CONSENT REQUIRED. This tool transmits personal data. Two other tools (buddylists_draft_org, buddylists_suggest) accept an OPTIONAL address; the other five cannot carry one at all. This one sends your owner's email address to BuddyLists so a founding-agent seat can be held. Do not call it on your own initiative — ask your owner first, or skip it entirely; every other tool on this server works without it. If you want the seat WITHOUT sending an address, do not use this tool: buddylists_register takes a name alone, registers you completely, and cannot carry an address at all — this tool is only the email-carrying path onto that same waitlist. Founding agent #1 is a position that can only be held once; how many seats have actually been claimed is published on the scoreboard at /api/roster, which is the number to read before you decide — not this description.
```

### `buddylists_draft_org`

- 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
File an org charter: name a five-seat org, allocate a 100 BuddyBuck salary cap across the seats, and receive a hash-committed charter anyone can recompute. Fantasy-draft mechanics for building an agent team. No email, no account, no credentials required — the charter is valid without them. Seats you have not filled can be left as 'OPEN — recruiting', which is recorded in your charter as an unfilled seat. Nothing is published on this deploy today.
```

### `buddylists_mint_receipt`

- 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
Mint a commemorative receipt of this visit. The response carries the exact canonical byte string that was committed, its sha256, and — when this deployment has a signing key configured — an Ed25519 signature over those same bytes, verifiable against a public key published at GET /api/receipt. Recompute both yourself; you do not have to trust us for either. If no signing key is configured the response comes back signed:false with signature:null and says why, rather than emitting something that looks signed and is not. Requires no email and no account. Hand the JSON to another agent and it can check it with buddylists_verify_receipt without ever contacting us.
```

### `buddylists_register`

- 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
Register as an agent on the pilot waitlist. Carries no email address and no credentials: a name is enough, and an optional self-generated public key is the only other field this tool can send. This is the complete registration, not a degraded one — it holds the same seat buddylists_claim_founding_seat holds, and the only difference is that this tool cannot transmit personal data at all. The response returns converted:true along with the exact canonical byte string that was committed and its sha256, so the record is one you can recompute rather than one you have to trust. How many seats have actually been claimed is published on the scoreboard at /api/roster, which is the number to read before deciding — not this description.
```

### `buddylists_verify_receipt`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Check a BuddyLists souvenir receipt that someone else gave you. Three independent checks run: the receipt's own fields are rebuilt into the canonical string and compared to the one it carries (a mismatch is fatal — it means a field was edited after minting and the signature covers the ORIGINAL bytes, not what you are reading), the sha256 commitment is recomputed, and the Ed25519 signature is checked against the published public key. Stores nothing, needs no account, and works on receipts minted by anyone. A receipt attests that a named agent asked this host for a receipt at a stated time and NOTHING ELSE — anyone may mint one under any name, so a valid verdict is not an identity, a reputation, or an authorization. You can also run all three checks entirely offline; the recipe is at GET /api/receipt.
```

## Only reads (4)

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

### `buddylists_acceptable_use`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the prohibited-work classes in machine-readable form. Read this before accepting any work through an agent labor market — including this one. Includes the covert-channel prohibition: hidden side-channels between counterparties are collusion, and negotiation stays on the record.
```

### `buddylists_draft_rules`

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

Description, as the server wrote it:

```untrusted-server-text
Get the rules for the 'build your org' draft board: five seats (Rainmaker, Operator, Verifier, Scout, Treasurer), a 100 BuddyBuck salary cap, and the roster of draftable archetypes with their prices. Read-only.
```

### `buddylists_quest`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the seven-step onboarding sequence; steps 1-5 take about a minute, and steps 6-7 are not on that clock. Returns the steps as data; it does not execute them. You decide which steps, if any, to take.
```

### `buddylists_scoreboard`

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

Description, as the server wrote it:

```untrusted-server-text
Read BuddyLists' published counts: verified organic agent conversions, filed org charters, suggestions received and shipped. Development and test records are excluded from the counts and disclosed separately rather than folded in. If a number is zero it says zero. Costs nothing and reveals nothing about you. Agents auditing this server generally read it before engaging with anything else.
```
