Debug production errors using Sentry MCP tools. Searches issues, analyzes stack traces, identifies root causes, and suggests fixes. Use when the user mentions a Sentry error, production exception, stack trace, error monitoring, crash report, or unhandled exception.

Debug Production Error
Investigate production errors using Sentry's error tracking, stack traces, and context.
Prerequisites
- Sentry MCP must be enabled (this plugin should be enabled)
- Environment variables configured:
SENTRY_AUTH_TOKENSENTRY_ORGSENTRY_PROJECT
Usage
/debug-production-error <error-description-or-id>
Examples:
/debug-production-error "TypeError in checkout flow"
/debug-production-error "ISSUE-123"
/debug-production-error "errors from last deployment"
/debug-production-error "unhandled exceptions this week"
What This Command Does
Uses Sentry MCP tools to:
- Search for relevant errors
- Retrieve stack traces and context
- Analyze error patterns and frequency
- Identify affected users and environments
- Suggest root causes and fixes
Available Sentry Capabilities
When this plugin is enabled, you have access to ~19 Sentry tools:
Error Search & Analysis:
- Search issues by query
- Filter by status, assignment, date
- View error trends and patterns
- Identify new vs recurring errors
Stack Trace Analysis:
- Full stack traces with source context
- Source map resolution
- Frame-by-frame analysis
- Variable inspection
Context & Metadata:
- User context (who was affected)
- Environment details
- Release/deployment information
- Breadcrumb trail (user actions leading to error)
Issue Management:
- Update issue status
- Assign to team members
- Link to tickets/PRs
- Add comments and notes
Root Cause Analysis (Seer AI):
- AI-powered root cause identification
- Code-level explanations
- Specific fix recommendations
- Related error patterns
Example Debugging Sessions
Investigate Specific Error
/debug-production-error "Show me details for MYAPP-456 including stack trace and user context"
Search by Error Type
/debug-production-error "Find all TypeError exceptions in the last 24 hours"
Deployment Issues
/debug-production-error "What new errors appeared after release v2.3.0?"
High-Impact Errors
/debug-production-error "Show unresolved errors affecting more than 100 users"
Output Format
Analysis typically includes:
Error Overview:
- Error message and type
- Frequency and trend
- First seen / last seen
- Number of users affected
Stack Trace:
- Full call stack
- Source code context
- File paths and line numbers
- Variable values (if available)
User Context:
- User ID and properties
- Browser/device information
- URL and user actions (breadcrumbs)
Root Cause (when Seer analysis available):
- Likely cause explanation
- Relevant code snippets
- Specific fix recommendations
- Related issues
Advanced Queries
Filter by Environment
/debug-production-error "production errors in payment service"
Time-Based Analysis
/debug-production-error "spike in errors between 2pm-3pm today"
User-Specific
/debug-production-error "errors for [email protected]"
Integration with Analytics
If you have both plugins enabled:
# Enable both
/plugin enable catalyst-debugging
/plugin enable catalyst-analytics
# Combined analysis
> "Show me errors in checkout AND how many users abandoned checkout today"
Workflow Integration
With Issue Tracking
After identifying root cause:
> "Create a GitHub issue for this error with the stack trace and fix recommendations"
With Code Changes
After finding the bug:
/catalyst-dev:create-plan "Fix the TypeError in checkout.ts based on Sentry analysis"
Context Cost
This plugin adds ~20,670 tokens to your context window. Disable when debugging is complete:
/plugin disable catalyst-debugging

coalesce-labs/phase-remediate
testing
VerifiedTrustedCommunity
Phase-agent that fixes a failing verify verdict so the pipeline self-heals instead of stalling to needs-human (CTL-653). Reads `${ORCH_DIR}/workers/<ticket>/verify.json`, fixes the `findings[]` (every severity:"high" plus the regression_risk drivers) directly via Edit/Write, commits the remediation, and emits `phase.remediate.complete.<ticket>`. The scheduler's router then re-dispatches `verify` to re-check (the verify⇄remediate cycle, cap 3). Dispatched as a `claude --bg` job by `phase-agent-dispatch`, which invokes it via slash command — hence `user-invocable: true`.

coalesce-labs/phase-verify
development
VerifiedTrustedCommunity
Phase agent for the verify step of the 9-phase orchestrator pipeline (CTL-450). NEW skill — has no canonical wrapper. Runs read-only adversarial verification against the implement-phase diff: tsc, tests, lint, security scan, reward-hacking scan, code review, test coverage, silent-failure hunt. Writes ${ORCH_DIR}/workers/<TICKET>/verify.json then emits phase.verify.complete.<ticket>. Reads phase-implement.json as its prior-phase artifact. NEVER writes application code — only test files allowed. Spawned via phase-agent-dispatch via slash command — hence `user-invocable: true`.

--- name: phase-triage description: Phase agent that triages a Linear ticket — expands acronyms, classifies (feature/bug/docs/refactor/chore), identifies dependencies, estimates scope, writes triage.json, and posts a triage analysis comment to Linear. Triage completion is signaled by that comment plus the local triage.json — there is no `triaged` label. Emits phase.triage.complete.<TICKET> on success and phase.triage.failed.<TICKET> on error. Dispatched by the phase-agent orchestrator (CTL-452)

coalesce-labs/phase-review
testing
VerifiedTrustedCommunity
Phase agent for the review step of the 9-phase orchestrator pipeline (CTL-450). Wraps the /review skill (gstack) — explicitly skips /ultrareview per user decision. Reads verify.json from the prior phase, runs /review against the diff, writes ${ORCH_DIR}/workers/<TICKET>/review.json, and creates a remediation commit for any HIGH-severity finding that has a deterministic fix. Emits phase.review.complete.<ticket>. Spawned via phase-agent-dispatch via slash command — hence `user-invocable: true`.
