Multi-phase, subagent-driven deep audit and remediation of codebase guidance (root agent instructions, docs, module context files, skills/agents references, task routing). Phase 1 subagents write verified findings only; Phase 2 subagents verify and fix guidance. Use when the user asks to audit, refresh, or fix agent context, CLAUDE.md or AGENTS.md drift, stale docs, contradictory rules, or run a context-guidance deep dive.
Use when the user asks to create, draft, save, revise, or improve a Codex Goal, GOAL.md, goal file, persistent objective, completion contract, or long-running Codex work objective. This skill must be used before inventing or saving any goal for Codex.
Use when the user wants to create, brainstorm, draft, or post social media content for X (Twitter), LinkedIn, or Instagram. This includes generating post ideas, writing captions or threads, adapting content across platforms, planning a posting cadence, or navigating to a platform's posting interface via browser tools. Trigger whenever the user mentions social media, posting, tweets, LinkedIn posts, Instagram captions, content calendars, thought leadership posts, or sharing research/business updates online — even if they just say something like 'I should post about this' or 'help me share this.'
Build Discounted Cash Flow (DCF) valuation models for commercial real estate (CRE). Calculate NOI-based cash flows, levered and unlevered IRR, equity multiple, DSCR, debt yield, exit cap rate reversion, and sensitivity analysis. Use for office, retail, industrial, multifamily, mixed-use, and hotel properties. Trigger on: CRE valuation, property DCF, NOI projection, cap rate analysis, IRR analysis, real estate investment return, acquisition underwriting, hold-period analysis, CRE sensitivity table.
Build discounted cash flow (DCF) valuation models in Excel specifically for commercial real estate (CRE). Use when creating CRE acquisition underwriting models, property-level DCF workbooks, NOI projections, rent roll buildouts, debt schedules, or IRR/equity-multiple return analyses in Excel or ExcelJS. Covers all CRE property types: office, retail, industrial, multifamily, mixed-use, hotel. Trigger on: 'CRE excel model', 'build underwriting model', 'property DCF excel', 'NOI projection spreadsheet', 'rent roll model', 'IRR excel', 'acquisition model', 'CRE waterfall', 'cap rate model'.
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
