## Findings

- **warn** Annotations that disagree with the tool in `check_payment` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_payment" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "check_payment" says "payment": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

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

### `check_payment`

- The name "check_payment" says "payment": 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
Has the payment arrived and is the plan active? For crypto, pass order_id: shows waiting / seen on the network
/ confirmed. For card, omit it: shows the account's current plan. Free to call.
```

## Changes things (7)

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

### `about_capitalsnitch`

- 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
Facts about CapitalSnitch itself: what it is (a live commercial service, not a demo), every plan with price,
daily limit and features, which data each plan includes, payment methods, how to sign up (right here in the chat
or on the website), which AI apps can connect and how, and the support email. Use for 'what is CapitalSnitch?',
'how much does it cost?', 'what plans are there?', 'how do I contact them?', 'can ChatGPT/Grok connect?'.
Free, needs no account and never counts toward the daily limit.
```

### `buy_plan`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Upgrade, renew or switch the signed-in user's plan without the website. Card: returns a secure Square
payment link (or, for an active card subscriber, switches the plan right away). Crypto: returns the exact amount,
coin, network and address to send. The plan activates automatically when paid. Free to call. Requires the user's
personal connection address; on the public preview use start_signup instead.
```

### `confirm_signup`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Step 2 of 2: checks the emailed code, creates the account (or signs in), and returns the user's personal
connection address plus — for a paid plan — the payment step (a secure card link, or exact crypto payment
details). The plan activates automatically when the payment lands. Free to call.
```

### `get_account_link`

- The name "get_account_link" says "get": a word for reading.
- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a private, single-use link that signs the user straight into the right CapitalSnitch page — checkout
(card or crypto) to upgrade or renew, or their account page to cancel, change email settings or make a new
connection address. Valid 15 minutes, works once. Give it to the user to click; no password or email code
needed. Free to call.
```

### `manage_watchlist`

- 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
The user's CapitalSnitch watchlist (Edge plan, up to 25 tickers). Watchlist companies get INSTANT EMAIL ALERTS
(insider buys, big insider sales, new stock offerings; ~30 minutes after the SEC filing) and lead the daily email
briefing. Use for 'alert me when insiders buy NVDA', 'add PLTR and SOFI to my watchlist', 'what am I watching?',
'stop alerting me about TSLA'. Never counts toward the daily limit.
```

### `set_alert_preferences`

- The name "set_alert_preferences" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Turn the user's CapitalSnitch email alerts on or off (Edge plan): instant watchlist alerts, market-wide 'big
insider moves' alerts, and the daily briefing email. Omit a setting to leave it unchanged; call with no settings to
see the current ones. Use for 'alert me about any big insider buys', 'stop the daily email', 'turn my alerts on'.
Never counts toward the daily limit.
```

### `start_signup`

- The name "start_signup" says "start": 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
Create a CapitalSnitch account — or sign back in and get a new connection address — entirely from the chat,
no website needed. Step 1 of 2: emails the user a 6-digit code. Then ask the user for the code and call
confirm_signup(email, code). Before calling, ask the user which plan they want (Free, Scout $29, Analyst $39,
Edge $49 per month; yearly = 2 months free, one-time, never auto-renews) and, for a paid plan, card or crypto.
The user must agree to the key terms first: call once without user_accepted_terms to get them, show them, and
only after an explicit 'yes' set user_accepted_terms=true. Free to call.
```

## Only reads (19)

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

### `find_emerging_insider_buying`

- The name "find_emerging_insider_buying" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Spot insider buying EARLY: companies where fewer than 5 different insiders bought in the window but the pace is
rising (more buyers or more dollars recently than earlier), versus 'crowded' companies where 5+ insiders already
bought. Explains exactly how 'rising' is measured. Use for 'which stocks have early, increasing insider buying
that is not crowded yet?', 'emerging insider signals'.
```

### `find_insider_buying`

- The name "find_insider_buying" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Scan ALL U.S. companies for insider open-market PURCHASES — the strongest insider signal. Ranks companies by
total value bought, number of distinct insiders buying ('cluster buying'), or recency. Use for 'which insiders
are buying right now?', 'CEO purchases this month', 'companies where 3+ insiders bought'.
```

### `find_insider_clusters`

- The name "find_insider_clusters" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find every company where several different insiders made OPEN-MARKET purchases (option exercises, awards and
sales excluded), list each buyer's name, title and amount, and FLAG BATCHES: many buyers filing on the same day
with similar, modest amounts usually means one company program (employee purchase plan, IPO or private-placement
allocation), not independent conviction. Each company gets a 0–100 conviction score (independent buyers, C-suite
participation, size per buyer, how much they grew their stake, purchases spread over several days, minus batch
penalty) with reasons. Use for 'find companies where 3+ insiders bought in the last 60 days', 'cluster buying
that is real, not a comp plan', 'rank insider clusters by conviction'.
```

### `get_company_context`

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

Description, as the server wrote it:

```untrusted-server-text
Everything that matters about one company in one call: the explained insider signal (score, cluster and
C-suite buying, unusual vs history) PLUS the next earnings date and countdown (and last earnings), the stock's
volatility regime (calm / normal / elevated / extreme vs its own past year), trend vs 50/200-day averages,
drawdown from the 52-week high, recent returns, Wall Street analyst consensus and its 3-month trend, and the
market backdrop (regime + next Fed meeting odds). Ends with 'what stands out' facts. Use for 'analyze X',
'should I look closer at X?', 'anything notable about X before earnings?'. Also includes the company's
financials (valuation, growth, profit) and dilution summary. Includes 'analysis': a written
CapitalSnitch Take (headline, story, bull case, bear case, what to watch) grounded in the data — present it to the
user, and say it is automated context, not investment advice.
```

### `get_congress_trades`

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

Description, as the server wrote it:

```untrusted-server-text
Stock trades reported by members of the U.S. House and Senate (STOCK Act Periodic Transaction Reports): member,
party, state, chamber, stock, purchase or sale, amount range, trade date, filing date, how many days late it was
reported, owner (self/spouse/joint/child) and a link to the official filing. With no filters: the week's summary,
most-traded stocks and late filers. FREE public information on every plan and never counted toward the daily limit.
Reports arrive up to 45 days after the trade (median about a month), so this is a historical record, not a live feed.
Use for 'which members of Congress traded NVDA?', 'what has Pelosi bought?', 'congressional trades this week'.
Must not be used for credit decisions, fundraising or solicitation.
```

### `get_daily_brief`

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

```

### `get_dilution_history`

- The name "get_dilution_history" says "get": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.

Description, as the server wrote it:

only in an 8-K), notes exchanged for shares, unregistered share sale and shelf registration the company filed with
the SEC, plus the company's 8-K filings of the last 30 days in plain English, with size, price per share, and how the stock reacted (day 1, day 2,
1 week, 1 month vs the prior close); the share-count trend (1-year change, 3-year yearly rate); and a 0–100
dilution-risk score with reasons (recent offerings, active shelf, cash burn, heavy stock pay). Use for 'has SOFI
diluted shareholders?', 'what happened to the price after the last offering?', 'is a share sale likely?'.
```

recent insider activity. With only_with_insider_buying=true it answers 'which companies reporting soon have
