ctx-doctor

name	ctx-doctor
description	Troubleshoot ctx behavior. Runs structural health checks, analyzes event log patterns, and presents findings with suggested actions.

Diagnose ctx problems by combining structural health checks with event log analysis.

When to Use

• User says "doctor", "diagnose", "troubleshoot", "health check"
• User asks "why didn't my hook fire?"
• User says "hooks seem broken" or "context seems stale"
• User says "too many nudges" or "something seems off"
• User asks "what happened last session?"

When NOT to Use

• User wants a quick status check (use /ctx-status)
• User wants to fix drift (use /ctx-drift)
• User wants to change hook messages (use ctx hook message)
• User wants to pause hooks (use /ctx-pause)

Diagnostic Playbook

Follow this triage sequence:

Phase 1: Structural Baseline

Run ctx doctor --json to get the full structural health report.

ctx doctor --json

Parse the JSON output. Note any warnings or errors.

Phase 2: Event Log Analysis (if available)

If the doctor report shows event logging is enabled, query recent events:

ctx hook event --json --last 100

If the user is asking about a specific hook:

ctx hook event --hook <hook-name> --json --last 20

If event logging is not enabled, note: "Enable event_log: true in .ctxrc for hook-level diagnostics."

Phase 3: Targeted Investigation

Based on findings, check additional sources:

• Hook config: read .claude/settings.local.json to verify hook registration
• Custom messages: run ctx hook message list to check for silenced hooks
• RC config: read .ctxrc to check configuration
• Reminders: run ctx remind list for pending reminders

Phase 4: Present Findings

Structure your report as:

## Doctor Report

### Structural health
- Summarize ctx doctor results

### Event analysis (if available)
- Patterns, gaps, or anomalies in event data
- Specific hook behavior observations

### Suggested actions
- [ ] Actionable items based on findings

Phase 5: Suggest, Don't Fix

Present actionable next steps but do NOT auto-fix anything. The user decides what to act on.

Available Data Sources

Source	Command	What it reveals
Structural health	ctx doctor --json	All mechanical checks
Event log	ctx hook event --json --last 100	Recent hook activity
Event log (filtered)	ctx hook event --hook <name> --json	Specific hook
Reminders	ctx remind list	Pending reminders
Hook messages	ctx hook message list	Custom vs default
RC config	Read .ctxrc	Configuration

Graceful Degradation

If event logging is not enabled, the skill still works with reduced capability. Run ctx doctor for structural checks and note that event-level diagnostics require event_log: true in .ctxrc.
