Claude Code: deny. ### `enqueue_solve` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Record a heads-up postflop solve request. Required: title, board, pot (bb), effective_stack (bb). The job stays pending: solver dispatch and billing are not configured, so this does not start a solve. ``` ### `submit_request` - The name "submit_request" says "submit": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text File a feature request or data request for the user, after telling them their question isn't covered and they agree. kind "data" is missing coverage (a game, format, stack depth, spot, or solve); kind "feature" is a missing capability (a tool, filter, export, or endpoint). Free with any key; the PokerData team reads every one. ``` ### `upload_hand_history` - The name "upload_hand_history" says "upload": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Secondary upload path for a small paste. Prefer get_upload_link and the hosted /upload page. Runs the same ingestion pipeline and returns hands parsed, tournaments parsed, and errors. Does not grade solver frequencies. ``` ## Changes things (1) Creates or changes something that can be changed back. Claude Code: ask. ### `get_started` - The name "get_started" says "get": a word for reading. - The description's first verb is "start": a word for a change. - 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 Start here with a new user. Returns the short set of questions to ask them (game, format, stakes, goal), a menu of what PokerData can do with the tools for each, what is free without a key, and how to file a feature or data request. Free, no key needed. ``` ## Only reads (28) Looks things up and changes nothing. Claude Code: allow. ### `compare_strategies` - The name "compare_strategies" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preferred tool for differences between two preflop or postflop contexts. The server fetches both strategies and returns action-frequency/EV deltas plus the largest postflop combo changes, avoiding two large node payloads. ``` ### `explain_combo` - The name "explain_combo" says "explain": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preferred tool for exact NLHE postflop hand questions. Returns a canonical context, exact action mix, action EV/loss when available, made-hand and draw classification, blocker facts, and same-rank-class suit comparisons. The server computes evidence; the agent should phrase causality as interpretation. ``` ### `find_hands` - The name "find_hands" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find hands the account has uploaded. Returns hand_id, session_id, handAt, position, cards, game, board, potType, street lines, and netBb. Solver grade buckets are not filled. If this account has no hands, offer the hosted upload page from get_upload_link (https://pokerdata.io/upload) instead of asking the user to paste histories into chat. ``` ### `get_board_report` - The name "get_board_report" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preferred tool for board-texture heuristics. Aggregates action frequencies and range/action composition across solved boards in one postflop pack. Results explicitly report sample breadth and use equal weight per board. ``` ### `get_config` - The name "get_config" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Table for one preflop game and stack, in big blinds: seats, stacks, blinds (sb 0.5, bb 1), ante, antePostedBy, stackIncludesAnte, openSizes (first-in raise-to), evUnit, evBaseline. Convergence is not published. stackIncludesAnte is true: the named depth is the starting stack and the 1bb BB ante is posted from it. openSizes at 40bb is open 2.2x (listing 2.2bb; node decodes code 40034 to 2.19bb) and SB 2.8x (2.8bb). 10bb is all-in/fold versus 50bb stacks, so stacks is null there. evs on nodes are small blinds relative to fold. Example: get_config({ game: "nlmtt8", stack: 40 }). ``` ### `get_exploitability` - The name "get_exploitability" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preflop exploitability for a game. No preflop dataset publishes exploitability, convergence, or iteration counts. The answer is not available; this tool never fills in a number. ``` ### `get_hand_results` - The name "get_hand_results" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Per-hand cumulative results for a winnings curve. `points` is [{ hand, bb }], oldest to newest, downsampled.

Description, as the server wrote it: ```untrusted-server-text The range a player takes one flop action with, from a solved pack: hand-class weights ("AA:1,AKs:0.42,...", same format as the preflop ranges) after every earlier flop action on the path. `path` ends in the action whose range you want, e.g. ["Check", "Bet 1.8", "Call 1.8"] for the check-call range. Bet-size tree. "33" = 33% pot on the flop, then 75% pot on the turn and river, plus all-in. "75" = 75% pot on every street, plus all-in. Compact and full detail apply to the other range tools; this returns the action range itself. ``` ### `get_queued_solve` - The name "get_queued_solve" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Look up one queued solve for this account. status is pending, running, done, or failed. solution_id is null until a worker exists. ``` ### `get_range` - The name "get_range" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The GTO range for one spot. `spot` is an action path of POSITION_ACTION pairs ending in the action whose range you want, e.g. NLHE cash "UTG_60%_HJ_Call", nlmtt8 "UTG_Open", or PLO "UTG_Open_HJ_3B". Add `hand` for one exact frequency and EV. Compact mode is default; PLO returns representative pure/mixed hands unless a hand is specified; plo5 returns the top hands by EV that take the action (limit up to 500 compact, 2000 full). ``` ### `get_range_metadata` - The name "get_range_metadata" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Index metadata for one preflop game, stack, and path: bundle stats for hold'em/PLO bundles, or the matching node row for plo5 and plo6hu. Does not return a strategy and does not invent exploitability. ``` ### `get_session_summary` - The name "get_session_summary" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One uploaded session's headline numbers: hero, game type, start and end times, hands played, net result in big blinds, and HUD rates (VPIP, PFR, 3-bet, open limp) as percentages with the sample size. Use it after list_my_sessions to report how a session went; use get_hand_results for its winnings curve and find_hands for individual hands. Returns an error for an unknown session id. Any key works, free trial included, and it never counts against the allowance. If this account has no hands, offer the hosted upload page from get_upload_link (https://pokerdata.io/upload) instead of asking the user to paste histories into chat. ``` ### `get_tournament_results` - The name "get_tournament_results" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text MTT results imported from tournament summary files. Money is in cents. Hand histories are not a source of buy-ins or prizes.

Description, as the server wrote it: ```untrusted-server-text Primary hand-upload path. Returns https://pokerdata.io/upload on this origin, with a short-lived signed token for the caller's account when signing is configured. Hand the URL to the user. Pasting histories into chat is the fallback. ``` ### `list_datasets` - The name "list_datasets" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List preflop datasets in the shipped tree documentation (stacks, positions, whether each bundle was analyzed). Preflop exploitability is not available. ``` ### `list_games` - The name "list_games" says "list": a word for reading.

Description, as the server wrote it: ```untrusted-server-text Every solved postflop pack: preflop line, positions (OOP vs IP), stack, pot, the bet-size trees it is solved under, and the solved boards. Boards use the spaced form ("3h 3d 2s"). NLHE packs list `sizingTrees`: "75" (75% pot every street, the pack id itself) and "33" (33% pot on the flop, then 75%, under the `-flop33` id); every postflop tool accepts either tree's packId. PLO5 packs (ids starting plo5-) solve one 33% flop tree, flop decisions only. Compact output lists board names per pack. Pass `pack` (the 75% id or the -flop33 id) for that tree's per-board detail and per-flop exploitability where the index publishes a number. Missing exploitability is omitted, never estimated.
