intercheck

Code quality guards and session health monitoring for Claude Code.

What this does

Long coding sessions accumulate pressure: context grows, small errors compound, and formatting drift becomes invisible. intercheck runs three PostToolUse hooks that catch problems as they happen rather than letting them pile up.

Context pressure tracking scores each tool call (+1.0 for normal calls, +1.5 for heavy tools like Task), decays 0.5 per 10 minutes of inactivity, and escalates through Yellow/Orange/Red thresholds. At Red (120+), it triggers an auto-checkpoint so you don't lose work to context exhaustion.

Syntax validation runs after every Edit and Write: Python, Shell, JSON, TOML, YAML, Go, TypeScript, and JavaScript. Catches the kind of malformed output that's easy to miss when you're moving fast.

Auto-formatting silently applies ruff, shfmt, gofmt, jq, or prettier after edits. No prompting, no ceremony: just consistent formatting without thinking about it.

Installation

First, add the interagency marketplace (one-time setup):

/plugin marketplace add mistakeknot/interagency-marketplace

Then install the plugin:

/plugin install intercheck

Usage

The hooks run automatically. To check session health manually:

/intercheck:status

Shows a dashboard with current pressure score, tool call count, estimated token usage, and threshold status.
