Invoice Review Compliance
A practice-area skill: it carries legal knowledge — a doctrine, a regime, a review standard — and applies it to your material.
What this skill does
Reviews outside counsel invoices against billing guidelines, flags non-compliant entries by category, and produces the documents needed to approve, reduce, reject, and communicate those decisions. Covers the full invoice compliance workflow: line-item review through to formal firm escalation. Works with or without an e-billing platform. Where an e-billing system is in place, LEDES format and UTBMS coding are hard gates. Where there is no e-billing system, invoice submission by email is the channel and UTBMS coding is a best-efforts flag.

Where it runs, and how to install it
Agent Skills are a format, not a product feature: a folder with a SKILL.md and whatever files it needs. Nothing inside one is model-specific.
- Claude
- Drop the skill folder into ~/.claude/skills/, or upload it in Settings → Capabilities. Claude loads it when the description matches what you asked for.
- Claude Code
- Same folder, per-project instead: .claude/skills/ inside the repository, so the skill travels with the work rather than with the machine.
- Any agent that reads SKILL.md
- A skill is a folder with a SKILL.md and whatever files it needs. Nothing in the format is model-specific, so a runtime that reads the file reads the skill.

- Matter Intake ScopingMatter scoping across the full pre-execution arc — organise client data into a structured brief, capture the agreed baseline, or reconstruct scope mid-flight. Use when making sense of client information before a proposal, scoping a new matter, running a kickoff, defining scope, mapping stakeholders, or inheriting a matter mid-flight.
- Billing Cycle ManagerOperational billing execution for legal matters. Monthly bill prep and billing instructions, LC invoice review and disbursement treatment, client billing query responses, cashflow modelling, and leverage and burn analysis (staffing mix, predicted total cost, margin trajectory).
- Budget and Fee ManagerBuild, monitor, and adjust fee budgets across the full matter lifecycle. At matter setup: translate scope into a phase-based fee estimate with contingency and AFA structure. In flight: run WIP reviews that explain variance, not just report it. When scope changes are confirmed: model the financial impact.
- Collaboration Platform AdvisorCollaboration platform configuration methodology for legal matter sites. Site architecture, workflow identification, dashboard design, data quality governance, and user adoption for SharePoint, Teams, and equivalent platforms. Outputs are platform-agnostic enough to brief IT or build simple automations.
- Continuous Improvement EngineCapture, structure, and recycle lessons from active and closed legal matters. Three modes: in-flight capture (triggered by scope changes, risk events, status updates), mid-matter review (phase gates or quarterly), and matter close retrospective. Lessons are formatted for immediate reuse, not filed and forgotten.
- Document Approval TrackerApproval cascade definition and tracking for multi-stakeholder document workflows. Internal review sequences, client approval workflows, regulatory review, overdue chasing with escalation logic, version control coordination, and cross-jurisdiction document dependencies.
