What it does

Pp Kalshi is an agent skill from mvanhorn/printing-press-library. Trade prediction markets, persist tick data, and answer category-level P&L questions Kalshi.com cannot. Trigger phrases: kalshi market price, track prediction market, kalshi portfolio P&L, kalshi correlate markets, use kalshi, run kalshi.

Its SKILL.md is about 6.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR. It works with Kalshi. The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.

When your agent uses it

  • Phrases: kalshi market price
  • Track prediction market
  • Kalshi portfolio P&L
  • Kalshi correlate markets

Example prompts

  • “/pp-kalshi”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Read, Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
  2. Verify: kalshi-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

What it can do on your machine

Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • go
    • claude
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • KALSHI_API_KEY
    • KALSHI_PRIVATE_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pp Kalshi loads about 6.6k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 2,990 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~6.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Kalshi — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the kalshi-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:
    bash
    npx -y @mvanhorn/printing-press-library install kalshi --cli-only
  2. Verify: kalshi-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

bash
go install github.com/mvanhorn/printing-press-library/library/payments/kalshi/cmd/kalshi-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Every Kalshi feature, plus a local SQLite store that records market prices on every sync — so movers, correlations, and price history work offline. Honest about read-only vs read/write keys, with --dry-run on every mutator and a global --read-only safe-mode lock for newsroom and bot deployments.

When to Use This CLI

Reach for kalshi-pp-cli when an agent needs price-over-time or category-level analytics on Kalshi markets — the public API only returns current prices and flat positions, so historical and aggregated questions require the local snapshot store. Use it for daily portfolio reconciliation, signal discovery via correlation across markets, and safe scripting against read-only API credentials.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Local state that compounds
  • portfolio attribution — See your realized P&L broken down by market category and series over any time window — answer 'did politics actually make money this quarter?' in one command.

    Use when an agent needs realized P&L sliced by Kalshi taxonomy — the API returns flat fills and settlements; this command joins them with the category metadata required to attribute correctly.

    bash
    kalshi-pp-cli portfolio attribution --since 2026-01-01 --by category --json
  • markets history — Show how a market's yes/no price moved over time, with a sparkline rendering — built from snapshots captured by every markets sync.

    Use when an agent asks 'how did this market move' or needs price-over-time for backtesting; the API only returns current price.

    bash
    kalshi-pp-cli markets history KXPRES-2028-DJT --since 2026-04-01 --sparkline
  • portfolio winrate — Calculate your win/loss ratio, expected value, and ROI across all settled positions, optionally sliced by category.

    Use when an agent evaluates trading-strategy performance; no Kalshi tool computes this.

    bash
    kalshi-pp-cli portfolio winrate --category sports --since 2026-01-01 --json
  • portfolio calendar — See upcoming settlements with your positions, expected payouts, and category breakdown over the next N days.

    Use when an agent needs to plan around upcoming settlements; the API surfaces positions and event expiries on different endpoints.

    bash
    kalshi-pp-cli portfolio calendar --days 14
  • markets movers — Find markets with the biggest price swings since the last sync — sorted by absolute delta or by volume change.

    Use when an agent needs to surface notable market activity; the API has no 'recent movers' endpoint.

    bash
    kalshi-pp-cli markets movers --window 24h --category politics --json
  • markets correlate — Compute Pearson correlation of two markets' price histories — find correlated events for hedging or signal discovery.

    Use when an agent investigates cross-market relationships; no API endpoint or other tool computes correlation across Kalshi markets.

    bash
    kalshi-pp-cli markets correlate KXFEDFUNDS-26FEB KXCPI-26FEB --window 30d --json
  • portfolio exposure — Break down total exposure by category with concentration warnings when any bucket exceeds a configurable risk threshold.

    Use when an agent needs portfolio-level risk; the API doesn't aggregate exposure by Kalshi taxonomy.

    bash
    kalshi-pp-cli portfolio exposure --by category --warn-threshold 0.4 --json
  • watch diff — Maintain a local watchlist of tickers; watch diff shows price/volume change vs the last sync per watched market — Riley's daily-snapshot ritual reduced to one command.

    Use when an agent tracks a stable set of markets across runs; the API has no watchlist concept.

    bash
    kalshi-pp-cli watch diff --since 24h
Honest auth
  • --read-only — Global env-var/flag lock that blocks every mutating command client-side regardless of which key tier is loaded — pair with --dry-run on every mutator for safe scripting against read-only credentials.

    Use when an agent runs against an unknown Kalshi key tier — the read-only key tier exists and mid-script 403s are common; this surfaces the constraint client-side before the API is hit.

    bash
    kalshi-pp-cli --read-only portfolio create-order --ticker KXTEST --side yes --count 1 --yes-price 50 --dry-run
  • subaccounts rollup — Aggregate positions, fills-today, balance, and exposure-by-category across every subaccount you can see — household view of risk and resting orders.

    Use when an FCM-tier user needs aggregate risk across subaccounts; no Kalshi tool surfaces a household view.

    bash
    kalshi-pp-cli subaccounts rollup --by category --json

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

bash
kalshi-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Politics-category P&L this quarter
bash
kalshi-pp-cli portfolio attribution --since 2026-01-01 --by category --agent --select 'rows.category,rows.realized_pnl,rows.fills'

Realized P&L attributed to Kalshi taxonomy; --select narrows the response to the three fields agents need.

Track the Fed-cut market on a watchlist
bash
kalshi-pp-cli watch add KXFEDFUNDS-26FEB && kalshi-pp-cli watch diff --since 24h --agent

Add ticker to local watchlist, then ask for the per-ticker delta since yesterday.

Correlate inflation and rate-cut markets
bash
kalshi-pp-cli markets correlate KXFEDFUNDS-26FEB KXCPI-26FEB --window 30d --agent

Pearson r computed locally over snapshot price series for both markets.

Safe paper-trading session
bash
kalshi-pp-cli portfolio create-order --ticker KXTEST-2026 --side yes --count 1 --yes-price 50 --action buy --dry-run

Both safety floors engaged: client-side read-only lock + dry-run; never reaches the API. (Pair with KALSHI_READ_ONLY=1 to engage the client-side safe-mode lock.)

Movers in sports markets, last 24h
bash
kalshi-pp-cli markets movers --window 24h --category sports --limit 5 --agent

Computes price deltas from market_price_history snapshots; works offline after a sync.

Auth Setup

Kalshi requires composed RSA-PSS signature auth: a UUID access key id (KALSHI_API_KEY) plus an RSA private key file (KALSHI_PRIVATE_KEY_PATH or KALSHI_PRIVATE_KEY). Kalshi issues two key tiers — read-only and read/write — and the CLI honors KALSHI_READ_ONLY=1 (or --read-only) as a client-side lock that blocks every POST/PUT/PATCH/DELETE before signing, regardless of which tier is loaded. Write commands run against a read-only key will surface a 403 from Kalshi; pair with --dry-run while debugging.

Run kalshi-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

  • Pipeable — JSON on stdout, errors on stderr

  • Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

    bash
    kalshi-pp-cli api-keys get --agent --select id,name,status
  • Previewable — --dry-run shows the request without sending

  • Offline-friendly — sync/search commands can use the local SQLite store when available

  • Non-interactive — never prompts, every input is a flag

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

json
{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

kalshi-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
kalshi-pp-cli feedback --stdin < notes.txt
kalshi-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.kalshi-pp-cli/feedback.jsonl. They are never POSTed unless KALSHI_FEEDBACK_ENDPOINT is set AND either --send is passed or KALSHI_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

SinkEffect
stdoutDefault; write to stdout only
file:<path>Atomically write output to <path> (tmp + rename)
webhook:<url>POST the output body to the URL (application/json or application/x-ndjson when --compact)

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

kalshi-pp-cli profile save briefing --json
kalshi-pp-cli --profile briefing api-keys get
kalshi-pp-cli profile list --json
kalshi-pp-cli profile show briefing
kalshi-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
