Project-grounded blast-radius tracing for code changes, PRs, diffs, files, symbols, or bugfixes, especially in Helpdesk-style repos. Use before editing, committing, merging, or reviewing when downstream callers, tests, routes, SQL, configs, schema, auth/tenant boundaries, external integrations, sibling bugs, or review-derived trap replays could be affected.
Standard rigorous multi-agent pipeline for bugs and build tasks that "must be workflowed". Engage when the user says "workflow this", "must be workflowed", "run the bug factory", "process the open bugs", "sweep and fix the bugs", or flags a build/bug task for the full pipeline. Sweeps open issues tagged `bug` (closes already-resolved ones), then runs each surviving bug through: confirm to plan/zoom-out/blast-radius convergence loop (fresh eyes) to build (one agent per file) to test to review (blast-radius + patch-or-fix + zoom-out) to verify (computer-use + Chrome on the local Cortex instance, explicit demonstrative proof) to ship (PR to dev, babysit, test on dev, PR to main, babysit, confirm on main). One agent = one job. Proof-or-STFU. The main merge is the only human-gated step.
Audit pull requests, branches, diffs, or local source files for semantically suspicious variable, identifier, member-access, and payload-field usage. Use when checking wrong-object bugs such as product.id versus rexProduct.id, source-system identity confusion, alias erasure, mismatched payload keys, or cross-system variable mixups; optionally publishes open-PR comments or merged-PR investigation issues and hands explicit issue targets to issue-to-green-pr when publication is authorized.
Review plans, fixes, and designs before implementation so code can be built mechanically. Use before coding, contract review, spec audit, readiness checks, or post-implementation contract verification. Fails vague contracts and missing Mechanical Build Packet fields.
Use when choosing daily Helpdesk service-to-domain migration candidates, table ownership moves, write seam consolidation, domain README gaps, or A-plus architecture burn-down work before implementation.
Use when inspecting Helpdesk domains for SRP, README, write-boundary, table ownership, or service-migration opportunities and when running one selected domain refactor lane through enterprise gates, PR audits, review loops, and explicit dev merge authorization.
Mandatory read-only pre-action and plan-review protocol for substantive coding, debugging, design, review, refactor, system-analysis, workflow, and business-context work. Use this skill to prevent first-match excitement by forcing source-grounded reading, explicit zoom-out system mapping, operator/business framing, root-cause, blast-radius, ownership, status/lifecycle coverage, plan viability, edge-case, SRP/refactor, schema/live-DB, headless UI, and verification thinking before implementation. Deep Think must not edit files, create worktrees, delegate coding, mutate systems, or fix bugs; it produces a decision-quality handoff only. Apply by default on bug fixes, feature work, refactors, plan reviews, code reviews, incidents, architecture, risky config, schema/query/data-sensitive work, and UI/PDF/file workflows. Exempt only pure chat and tiny low-risk housekeeping.
Use when preparing to deploy code to production, merging to main, running migrations on production databases, or setting environment variables on Render. Use when the user mentions "deploy", "push to production", "merge to main", "run migrations", or asks about pending deploy items. Also use when reviewing what needs to happen before a feature goes live.
