What it does
Prediction Markets Analysis is an agent skill from OctagonAI/octagon-mcp-server. Generate Kalshi prediction market research reports or fetch structured event history. Use when the user mentions Kalshi, prediction markets, market probability, expected return, or event history.
Its SKILL.md is about 470 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, covering Report writing. It works with Kalshi and Model Context Protocol. The repository describes itself as: An MCP server for public & prediction markets research. Ask natural-language questions and get structured, source-backed answers across SEC filings, earnings transcripts, company… The licence is MIT.
When your agent uses it
- The user mentions Kalshi
- Prediction markets
- Market probability
- Expected return
Example prompts
- “/prediction-markets-analysis”
What it can do on your machine
Read from SKILL.md and the folder at commit a323463. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
kalshi.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Prediction Markets Analysis loads about 465 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 133 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

}Tool selection rules
- Use
octagon-prediction-markets-agentfor analyst-style reports - Use
prediction_markets_historyfor structured history, pagination, or time filtering - If the user wants guaranteed fresh data, set
cachetofalse
Output expectations
- Compare model probability to market probability
- Highlight edge, expected return, and risk factors
- Surface missing Kalshi URL immediately when absent
Follow-up prompts
- "Refresh the report instead of using cache."
- "Show the event history with analysis included."
- "Summarize the largest drivers of divergence between model and market."
