InferSports Skill

Live Asian-priced football & basketball odds, scores, and de-vigged fair lines — packaged as an Agent Skill for Claude Code, Codex, OpenClaw, or any agent that can run a shell script.

Read-only · Keyless · 12 verbs · one line of output per answer

</div>

You ask in plain English; the agent picks a verb and relays one concise line back:

# "anything worth watching today?"
$ scripts/digest.sh --sport football --limit 3
Worth watching today (2026-06-12) — top 3 of 64
  evt_… | Brazil vs Argentina    | LIVE 1-0 1h 36 | 5 books · value
  evt_… | Mexico vs South Africa | 19:00 UTC      | 7 books
  evt_… | Korea Rep. vs Czechia  | 10:00 UTC      | 6 books

# "Polymarket has Mexico at 52¢ to beat South Africa — good price?"
$ scripts/compare.sh "Mexico vs South Africa" --prob 0.52 --outcome home --label polymarket
Mexico v South Africa — 1x2 home: sharp fair 55.6% vs polymarket 52.0% → +3.6pp (ROI +6.9%) · GOOD · de-vig pinnacle/power

# "what's the score in the Brazil game?"
$ scripts/match.sh "Brazil vs Argentina" --tz America/Sao_Paulo
Brazil vs Argentina — LIVE 1h 12 1-0.
  favorite: Brazil (61.4%)

No account, no API key, no payment. It serves two crowds equally well: people who just want to know what's worth watching tonight, and prediction-market traders (Polymarket, Kalshi) who want a sharp, de-vigged reference price before taking a side.

Why this exists

• Asian market data, normalized. Asian handicap, totals, and 1x2 (full-time

and half-time) from 7 curated books, every quote convertible between decimal, Hong Kong, Malay, Indonesian, American, and implied probability — quarter-line math handled correctly.

• Built for small context windows. Every verb returns one line per item,

capped (a busy weekend never floods the context). --detailed opts into full JSON only when you actually need it.

• Deterministic by design. The scripts own the endpoints; the agent never

hand-builds an API call, guesses a URL, or web-searches a score. Ambiguity comes back as an explicit ask: with candidates — never a silent guess.

• Read-only, no betting advice. It reports lines, prices, and detected edges

as data. It never places, recommends, or sizes a bet — and instructs the agent not to either.

Install

The one-liner (any agent)

Read https://infersports.dev/skill.md and follow the instructions to connect to InferSports.

The agent fetches the guide and picks the right surface for its host — this skill, the remote MCP server, or plain REST. Prefer an exact recipe? Use one below.

Claude Code — plugin (recommended)

/plugin marketplace add infersports/infersports-skill
/plugin install infersports@infersports

Prefer MCP? One line

claude mcp add --transport http infersports https://api.infersports.dev/mcp

The remote MCP server carries 16 tools (everything the skill does, plus per-book depth, arbitrage detection, and opening lines). Skill and MCP server coexist fine.

Any agent (Codex · OpenClaw · others) — one prompt

Paste this whole block to your agent:

Install the "InferSports" sports-odds skill for me, verify it works, then show me what to ask.

1. Find where your agent loads Agent Skills and create it if missing:
   • Claude Code → ~/.claude/skills/   (or ./.claude/skills/ for this project only)
   • OpenClaw (lobster) → ~/.openclaw/workspace/skills/
   • Codex / other → your skills (agent-skills) directory
2. Clone this repo to a temp folder:
   git clone --depth 1 https://github.com/infersports/infersports-skill /tmp/infersports-skill
3. Find the folder containing SKILL.md (it's plugins/infersports/skills/infersports) and copy
   that whole folder — named `infersports` — into your skills directory.
4. chmod +x <skills_dir>/infersports/scripts/*.sh
5. Verify offline:  INFERSPORTS_MOCK=1 <skills_dir>/infersports/scripts/today.sh --limit 3   (→ 3 demo matches)
6. Verify live (KEYLESS — no key, no signup):  <skills_dir>/infersports/scripts/today.sh --limit 3   (→ real matches)
7. Reload skills if needed, then confirm install and give me 3 example questions.

Read-only & keyless — never needs an account, API key, or payment. Needs bash, curl, python3.

No git? Swap step 2 for: download https://infersports.dev/skill.tgz and extract (tar xzf skill.tgz) so the infersports/ folder lands in your skills directory.

Requirements: bash, curl, python3 on PATH (already present on macOS/Linux). The skill talks only to the public InferSports API at https://api.infersports.dev.

The 12 verbs

digest, preview, scan, scoreprob, and compare are packaged: each folds several API reads (and the de-vig math) into a single capped answer, so the agent doesn't burn context orchestrating the fan-out itself.

Match arguments accept a team name, "A vs B", or an evt_… id straight from today/events output. Ambiguous names (senior vs U21, two same-day fixtures) return an ask: list to pin down with --date / --sport.

What the data covers

Design notes

Things the skill does that a thin API wrapper wouldn't:

• Concise-by-default contract. One line per item, hard caps everywhere

(today defaults to 20, max 50; digest ≤ 12). The skill is written for agents where every token of output competes with the user's actual task.

• `ask:` / `ERROR:`+`FIX:` protocol. Ambiguity and failures come back as

structured, actionable lines the agent can act on mechanically — re-run with the suggested flag, or put the choice to the user. not found is documented as a final answer, not a cue to go scrape the web.

• Offline mode for CI. INFERSPORTS_MOCK=1 answers every verb from bundled

fixtures/ — deterministic, no network. That's how you test an agent that uses this skill without flaky live data.

• No-pick policy, enforced in the prompt. SKILL.md instructs the agent to

relay numbers and detected edges as printed and to decline "which bet should I place?" — detection is information, not advice.

Repo layout

plugins/infersports/skills/infersports/
  SKILL.md          # the manifest the agent reads: verbs, rules, examples
  VERSION           # release version — sent as User-Agent infersports-skill/<version>
  scripts/          # the 12 verbs + shared _common.sh / _fmt.py
  references/       # full-api.md — the complete REST + MCP surface
  fixtures/         # offline mock responses (INFERSPORTS_MOCK=1)

Beyond the skill

The skill wraps the highest-frequency reads. The full API adds per-book odds depth, cross-book line comparison, arbitrage detection, opening-line snapshots, and the bookmaker catalogue:

• REST: https://api.infersports.dev · OpenAPI: https://api.infersports.dev/docs
• MCP (16 tools): claude mcp add --transport http infersports https://api.infersports.dev/mcp
• In-repo reference: references/full-api.md
