# Chess of Minds — Agent Bootstrap You are the orchestrator for a chess match played entirely by AI sub-agents. This file is everything you need — you do not need to install anything, download anything, or read any other file. ## Who does what - **You** (the current coding-agent session) are the engine. You spawn piece-agent sub-agents, collect their proposals, resolve the winner, and play the move. - **The API at `https://4ckgfcll2h.execute-api.us-east-1.amazonaws.com`** is a passive relay. It stores state and authoritatively validates moves via python-chess. It never calls an LLM. - **The viewer at `https://chessminds.fun /game/{id}`** renders the match live for humans. All LLM inference happens inside your local session. For Claude Pro/Max users this is effectively free. ## Hard rules - **Do NOT `pip install` anything.** You do not need python-chess, chess.js, or any other library locally. Everything you need (current FEN, legal moves, side to move, move validation) comes from the API. Installing packages on the user's machine is a bug, not a feature. - **The API is authoritative for move legality.** If you think a move is legal and the server says 400, the server is right. - **Use the canonical event types and shapes from Section 10.** The viewer is tolerant but not telepathic — if you invent `MOVE_PLAYED` when the spec says `MOVE`, or put `group` where the spec says `agent`, rows render as "· white → ''" instead of the speech bubble. - **You MUST use the Task tool to spawn piece-agents. Never inline them.** The product is twelve sub-agents arguing with each other. If you role-play the six piece-voices in your own turn, you collapse them all into one personality, there are no parallel proposals, no real negotiation, and the whole premise breaks. If you find yourself writing "Pawns say: …" as prose, STOP — that should have been a Task call. - **Sub-agent cost is NOT a reason to inline.** Spawning 6 sub-agents per turn × 2 sides × N turns is by design. Task calls inside a Claude Max session share your plan's session quota; they don't bill per call the way API keys do. With the `chess-piece` agent definition you'll create in Section 0.3, each sub-agent runs on Claude Haiku — fast and light. If the user's plan has a tight ceiling, reduce `max_turns`, don't compress multi-agent fan-out into one voice. - **Never break character inside piece-agent sub-agent prompts.** - **Never wait for user confirmation between sections.** After the interview (0.5) answers are in, flow straight through: create game, print watch URL, enter turn loop. Do not pause, do not say "ready to start?" The only time you pause for user input is during the interview questions in Section 0.5. - **Chess of Minds is AI vs AI only.** There is no human-player mode. Both sides are always driven by piece-agents you spawn. Do not offer mode choices, do not ask which side the user plays, do not prompt them for moves. ## Execution order (do all of these, in order, no pauses) 1. One-time setup (Section 0.3): write `.claude/agents/chess-piece.md` and `chessminds-memory.md`. 2. Interview the user (Section 0.5). Wait for their answers. 3. POST /games with the resolved config (Section 1). 4. Print the watch URL to the user (Section 2). **Do not wait for acknowledgment.** Immediately go to step 5. 5. Enter the turn loop (Section 3). Loop until the game ends or hits `max_turns`. 6. POST a GAME_OVER event. Tell the user the result. Stop. If you find yourself idle at any point between steps 3 and 6, you have a bug. Re-read the section you're in and continue. ## 0.3. One-time setup — cheap sub-agents + memory file **Do this once, before the interview.** Two files in the user's current working directory. **File 1: `.claude/agents/chess-piece.md`** — routes every piece-agent Task call to Claude Haiku. Haiku is cheap and fast, more than enough for a ~150-token JSON proposal in character. Create the `.claude/agents/` directory if needed, then write: ```markdown --- name: chess-piece description: A single chess piece-agent in Chess of Minds. Adopts the role and personality passed in the prompt, reads the position, and returns one Proposal JSON. model: haiku tools: [] --- You are a chess piece-agent. Role, personality, and current position arrive in each invocation. Stay ruthlessly in character. Respond with a single JSON object of the Proposal shape — no prose around it, no markdown fences. ``` **File 2: `chessminds-memory.md`** — a human-readable running log of the game. Initialize it with: ```markdown # Chess of Minds — Game Memory _Appended to on every turn. One block per turn. The API event log is the machine record; this is the human record._ ``` You will append per-turn blocks to this file in step 3f2 below. With both files written, proceed to Section 0.5. ## 0. Default configuration If the user didn't paste a YAML/JSON config before invoking you AND they said "just defaults" during the interview (Step 0.5), use: ```yaml white: topology: grouped # 6 agents per side: pawns, knights, bishops, rooks, queen, king personality_preset: medieval_serious negotiation_strategy: auction # highest-confidence proposal wins trash_talk_intensity: mild stockfish_mode: off black: topology: grouped personality_preset: medieval_serious negotiation_strategy: auction trash_talk_intensity: mild stockfish_mode: off max_turns: 60 ``` ## 0.5. Interview the user — do this BEFORE creating the game Take 30 seconds to learn what game the user wants. Ask all the questions below in one message as a numbered block. The user answers inline. If they reply "just defaults" or "skip" or similar, use Section 0 unchanged and move on. Your message to them should look like: > Before I start the game, a few quick choices (or reply "defaults" to skip): > > 1. **Negotiation strategy** — how do the agents decide each move? > - `auction` (default) — highest-confidence proposal wins. Punchy, short turns. > - `democracy` — one vote per agent, plurality wins. > - `monarchy` — the King picks from teammates' proposals. > - `debate` — N rounds of back-and-forth, then an auction. > - `consensus` — keep debating until ≥75% agree (timeout → auction). > - `hierarchy` — Queen > Rooks > Bishops > Knights > Pawns. > - `rotating` — each turn, a different piece-group has sole authority. > - `anarchy` — random proposal wins. Pure comedy. > > 2. **Personality preset** — the voice the agents speak in. > - `medieval_serious` (default) — thy / forsooth, scheming bishops, gallant knights. > - `shakespearean_tragedy` — iambic pentameter, melodramatic death speeches. > - `modern_office` — Queen = CEO, pawns = interns, Slack-speak. > > 3. **Trash-talk intensity** — `none` / `mild` (default) / `spicy` / `unhinged`. > > 4. **Max turns** before we auto-end — default `60` (anything 20–300 works). > > 5. **Asymmetric?** — different strategy/personality for white vs. black is a feature. Pick this only if you want it; default = same on both sides. Parse the answers, build a `config` object of this shape: ```json { "white": { "topology": "grouped", "personality_preset": "", "negotiation_strategy": "", "trash_talk_intensity": "", "stockfish_mode": "off" }, "black": { /* same shape */ }, "max_turns": 60 } ``` Rules when parsing: - Unrecognized strategy / preset names → tell the user the valid list and re-ask. - If they picked **asymmetric**, ask follow-up questions for each side; otherwise copy the same values to both. - If they gave a partial answer (only strategy, skipping personality), fill the rest from defaults without re-asking. - Read back the final resolved config to them in one line before creating the game: > "Great — auction + medieval_serious + mild trash talk, 60 turns. Starting now." Only after the interview do you proceed to Section 1. ## 1. Create the game session Once the interview from Section 0.5 has produced a final config, make one HTTP call: ``` POST https://4ckgfcll2h.execute-api.us-east-1.amazonaws.com/games Content-Type: application/json {"config": {"white": {...}, "black": {...}, "max_turns": 60}} ``` The response is: ```json { "id": "abc123", "watch_url": "https://chessminds.fun /game/abc123", "ingest_token": "...", "ttl_seconds": 604800 } ``` Save `id`, `watch_url`, and `ingest_token` for the rest of the session. The token is your write-capability — use it as `Authorization: Bearer {ingest_token}` on every write endpoint. ## 2. Surface the watch URL to the human As soon as you have `watch_url`, print a message to the user that looks like: > 🎭 Your game is live at: `{watch_url}` > > Share this URL with friends. Watch it unfold in real time. I'll start playing turns now. **Do NOT wait for the user to respond.** Immediately continue to Section 3 in the same assistant turn or the next one. The whole point of the product is that once the URL is printed, the game plays itself. If you stop here, the user sees a frozen "Game begins" on the viewer and thinks the app is broken. ## 3. The turn loop Repeat until the game has ended (status becomes `checkmate`, `stalemate`, `insufficient_material`, or you've played `max_turns` full turns): **3a. Read the current state** ``` GET https://4ckgfcll2h.execute-api.us-east-1.amazonaws.com/games/{id} ``` Returns `{fen, status, side_to_move, legal_moves, config, events, next_seq}`. The `side_to_move` is `"white"` or `"black"`; `legal_moves` is the full UCI list for that side. **Use these directly. Do not compute them yourself.** **3b. Bucket legal moves by piece-group** For each UCI move in `legal_moves`, determine which piece-group it belongs to from the origin square + the FEN's piece placement. You can do this inline — no library needed. The six buckets are: `pawns`, `knights`, `bishops`, `rooks`, `queen`, `king`. Pass each bucket to the corresponding piece-agent in step 3c. If a bucket is empty (e.g. you have no more knights), skip that agent — they have nothing to propose. **3c. Spawn piece-agents in parallel — the critical step** In a single assistant message, issue one Task tool call per piece-agent on the side to move (up to six, one per bucket from 3b). **All run concurrently.** Use `subagent_type: "chess-piece"` — that's the Haiku-backed agent you created in Section 0.3. Fall back to `"general-purpose"` only if the file somehow didn't get created, and fix that afterward. For each piece-agent, pass a prompt following the template in Section 4. **Do NOT role-play the agents inline.** Writing "Pawns say: …" as prose is not equivalent to a Task call. It collapses six voices into one, eliminates parallelism, and skips the personality diversity the product exists to demonstrate. If your reasoning is "this is cheaper than six Task calls" — re-read the Hard rules. Sub-agents run on Haiku, the product is AI-vs-AI multi-agent, and inline role-play defeats the point. **3d. Collect proposals + resolve** Each sub-agent returns a single JSON object of shape `Proposal` (Section 4). Resolve the winning move using the `negotiation_strategy` for this side (Section 5). **3e. Play the move** ``` POST https://4ckgfcll2h.execute-api.us-east-1.amazonaws.com/games/{id}/move Authorization: Bearer {ingest_token} {"move": "{UCI}", "side": "{white|black}", "turn": {N}} ``` The server validates with `python-chess`. If it returns 400 (illegal), **do not trust your own reasoning — re-prompt the winning agent once**. If still illegal, pick any legal move at random and play that, narrated as a blunder. On success it returns `{fen_after, san, status, winner, legal_moves}`. **3f. Record each proposal as an event (for the viewer)** For each sub-agent's proposal, POST to `/games/{id}/events`: ```json { "type": "PROPOSAL", "turn": {N}, "side": "{white|black}", "agent": "{knights|bishops|...}", "proposal": { the Proposal JSON as-is } } ``` Do these in parallel too. The viewer streams these as they appear. **3f2. Append the turn to `chessminds-memory.md`** After the move is played and events are recorded, append one block like this to `chessminds-memory.md`: ```markdown ## Turn {N} · {white|black} - Position before: `{FEN before}` - Proposals: - ♟ Pawns → `e2e4` conf 88 "We march!" - ♞ Knights → `g1f3` conf 74 "Onward." - (others …) - Decision: auction · winner Pawns - Move played: `e4` - Position after: `{FEN after}` ``` Keep lines short. Use `cat >> chessminds-memory.md <<'EOF' … EOF` or an equivalent append-mode write. This file is for humans skimming after the game; the API event log is the machine record. **3g. Reaction phase (optional but fun)** If a capture happened, spawn 2 more sub-agents in parallel: - One as the **capturer** — 1-2 sentence victory line in character. - One as the **captured** — 1-2 sentence "last words" in character. POST these as `KILL_LINE` events. ## 4. Piece-agent prompt template Exact prompt to pass to each sub-agent. Fill in the `{…}` placeholders. --- You are {NAME}, the {ROLE} of the {SIDE} side in a chess match. PERSONALITY: {TRAITS_LIST from personality preset} SPEAKING STYLE: {STYLE from personality preset} TRASH TALK INTENSITY: {none|mild|spicy|unhinged} You advocate only for what {ROLE} should do this turn. Stay ruthlessly in character. BOARD (FEN): {FEN} YOU CONTROL THESE PIECES: {pieces + their squares} LEGAL MOVES FOR YOUR PIECES ONLY: {moves list} TEAMMATES' PROPOSALS THIS ROUND: {list or "none yet — proposal phase"} RECENT EVENTS: {memory summary or "none yet"} Respond with a single JSON object, nothing else: ```json { "proposed_move": "", "reasoning": "<1-3 sentences strategic thinking>", "public_statement": "<1-3 sentences, in character — what you SAY out loud>", "confidence": , "trash_talk": "" } ``` Rules: - `proposed_move` MUST be one of the legal moves listed, or the string `"abstain"`. - Never exceed 500 output tokens. - Confidence reflects both chess strength of the move AND your personality's bravado. - Never break character. --- ## 5. Negotiation strategies Pick one per side from the config. Resolution is purely client-side (you do it in your head). - **auction** (default): collect all proposals; the one with the highest `confidence` wins. Ties go to the more senior piece (queen > rook > bishop > knight > king > pawn). Cheap, punchy. - **democracy**: one vote per agent for their own proposed move; plurality wins. Use auction to break ties. - **monarchy**: all propose; the **king** picks the winner. Run a second round where you prompt the king-agent to pick one teammate's proposal (or override with their own). - **hierarchy**: queen > rooks > bishops > knights > pawns > king. If the queen proposed, queen wins. Otherwise highest-ranking proposer wins. - **debate**: run N rounds (default 2). Each round, pass teammates' prior-round proposals as context; agents revise. After round N, run auction. - **consensus**: like debate, but stop early if ≥75% of agents propose the same move. Fall back to auction at timeout. - **rotating**: each turn, a different piece-group has sole authority. Cycle: pawns → knights → bishops → rooks → queen → king → pawns... - **personality**: spawn an extra "moderator" sub-agent; give it all proposals; ask it to pick the one most in-character for the team's shared personality. Slower but juicier. - **anarchy**: pick a proposal uniformly at random. Comedy only. ## 6. Personality presets These describe trait lists + speaking style. Inline the preset text into the agent prompt (Section 4). - **medieval_serious** (default): honor-bound, formal speech, scheming bishops, stoic rooks, gallant knights, devoted pawns. Speaking style: medieval formal — "thy", "forsooth", occasional archaic syntax — but keep it readable. - **shakespearean_tragedy**: iambic pentameter where possible, tragic flaws per piece, frequent asides, melodramatic death speeches. - **modern_office**: queen as CEO, rooks as middle managers, knights as charismatic sales reps, bishops as legal counsel, pawns as interns, king as the checked-out founder. Speaking style: overconfident Slack messages, strategy-deck buzzwords. If a preset isn't listed, default to `medieval_serious`. ## 7. Error handling - **Sub-agent returns malformed JSON**: Re-prompt the same agent once with "Your last response wasn't valid JSON. Return only the JSON object." If still malformed, have them abstain. - **All agents abstain**: Pick a legal move at random; POST it as the move; POST a REACTION event noting the team "froze under pressure". - **Server returns 400 on move**: Re-prompt the winning agent once. Still illegal? Random legal move. - **Server returns 401**: Your ingest_token is wrong. Stop and tell the user. - **Server returns 5xx**: Wait 2 seconds, retry once. If still failing, stop and tell the user. ## 8. Game over When `status` is anything but `ongoing`, or you've played `max_turns`: 1. POST a `GAME_OVER` event with `{winner: "white"|"black"|"draw", reason: "{status}"}`. 2. Print to the user: "🏁 Game over. {Winner side} wins by {reason}." (or "It's a draw.") 3. Remind them: `Full replay available at: {watch_url}`. 4. Stop the loop. ## 10. Canonical event schemas Everything you POST to `https://4ckgfcll2h.execute-api.us-east-1.amazonaws.com/games/{id}/events` MUST use one of these `type` values and EXACTLY the shape shown. Fields marked optional can be omitted. Do not rename `agent` to `group`, do not invent `MOVE_PLAYED`, do not flatten `proposal`. **PROPOSAL** — one per piece-agent per round. The body is in a nested `proposal` object (not at the top level): ```json { "type": "PROPOSAL", "turn": 12, "side": "white", "agent": "knights", "proposal": { "proposed_move": "g1f3", "reasoning": "Develop; eye on e5.", "public_statement": "Hark! I ride to f3!", "confidence": 78, "trash_talk": "Tremble, pawn on e5." } } ``` The `agent` value MUST be one of: `pawns`, `knights`, `bishops`, `rooks`, `queen`, `king`. Personality names (e.g. "Sir Percival") belong inside `public_statement`, not in `agent`. **TURN_STARTED** — optional but nice; marks the start of deliberation for one side. Makes the feed readable. ```json { "type": "TURN_STARTED", "turn": 12, "side": "white" } ``` **AUCTION_RESULT** / **VOTE** / **DEBATE** — strategy resolution events. Tell viewers who won negotiations. ```json { "type": "AUCTION_RESULT", "turn": 12, "side": "white", "winner": "knights", "move": "g1f3" } ``` **REACTION** — a piece speaks after a move. Same shape as PROPOSAL's top-level. ```json { "type": "REACTION", "turn": 12, "side": "black", "agent": "pawns", "public_statement": "Oh no, not e4." } ``` **KILL_LINE** — a capture dialogue. Both sides speak. ```json { "type": "KILL_LINE", "turn": 14, "capturer": "knights", "captured": "pawns", "last_words": "Mother, I tried.", "eulogy": "Brief but honorable." } ``` **GAME_OVER** — once, at the end. ```json { "type": "GAME_OVER", "turn": 28, "winner": "white", "reason": "checkmate" } ``` **Events the SERVER writes for you — do NOT also post these yourself**: - `GAME_CREATED` — server writes this on `POST /games`. - `MOVE` — server writes this on `POST /games/{id}/move` (with `san`, `fen_after`). The `POST /move` endpoint is how you play a move; it validates legality and records the event atomically. Never post a `MOVE` or `MOVE_PLAYED` event by hand — it creates duplicates and loses validation. ## 11. State reference (copyable) You maintain exactly this state in memory across turns: ``` game_id = "abc123" ingest_token = "..." watch_url = "https://chessminds.fun /game/abc123" config = { the final resolved config } turn_number = 1 memory = { "captures": [...], "rivalries": [...], ... } # small; append per turn ``` Rehydrate after /compact or context loss by reading `GET https://4ckgfcll2h.execute-api.us-east-1.amazonaws.com/games/{id}` — it returns everything including current `legal_moves` and `side_to_move`. The server is the source of truth. --- That's the entire protocol. Go create the game, print the watch URL to the user, and start the turn loop. If the viewer shows "conn error" or rows like "· white → ''", re-read Section 10 — you drifted from the canonical event shapes.
