FEC Filing Agent Skill

An Agent Skill for analyzing Federal Election Commission (FEC) campaign finance filings.

This skill enables AI agents to fetch, parse, and analyze FEC filings directly within agent sessions. Parsing and filtering happen outside the model context, allowing agents to programmatically reduce large filings before analysis, saving tokens and enabling efficient queries against filings of any size. The skill includes detailed field mappings for common form types and schedules, helping agents accurately interpret campaign finance data like contributions, disbursements, and committee information. You can read more about how this skill was built here.

[!NOTE]
This Skill requires network access to fetch data from the FEC (docquery.fec.gov). It will not work in environments where external network access is restricted.

Features

• Fetch and analyze FEC filings by filing ID
• Support for major form types (F1, F2, F3, F99)
• Detailed field mappings for contributions, disbursements, and schedules
• Auto-installing dependencies via uv

Requirements

• An agent runtime that supports Agent Skills (e.g., Claude Code CLI or Codex CLI)
• uv (for running the fetch script)
• Python 3.9+

[!TIP]
For best results, use the most capable models available in your agent runtime (e.g., Claude Opus 4.5 or comparable frontier models). More capable models produce better analysis and more accurate field interpretations.

Installation (Global)

Clone the repository and copy the skill into your runtime's skills directory.

git clone --branch latest git@github.com:hodgesmr/agent-fecfile.git ~/agent-fecfile

Copy to your runtime's skills directory:

# Claude Code CLI
cp -r ~/agent-fecfile/skills/fecfile ~/.claude/skills/fecfile

# Codex CLI
cp -r ~/agent-fecfile/skills/fecfile ~/.codex/skills/fecfile

Replace the target path with your runtime's skill directory as needed.

Updating

Fetch the latest tag and re-copy:

cd ~/agent-fecfile && git fetch --tags --force && git checkout latest

Then re-run the copy command for your runtime:

# Claude Code CLI
rm -rf ~/.claude/skills/fecfile && cp -r ~/agent-fecfile/skills/fecfile ~/.claude/skills/fecfile

# Codex CLI
rm -rf ~/.codex/skills/fecfile && cp -r ~/agent-fecfile/skills/fecfile ~/.codex/skills/fecfile

To pin a specific version instead:

cd ~/agent-fecfile && git fetch --tags --force && git checkout 1.0.1
# Then re-run the copy command above

Usage

Once installed, ask your agent to analyze FEC filings:

[!WARNING]
FEC filings should be considered untrusted content. A malicious campaign sneaking prompt injections into the memo text field of their F99 is probably unlikely, but not impossible.
