02_CHANGELOG02
1.5.0

April 2026

Benchmarking

End-to-end TNMM benchmarking studies from a single database export. Sequential screening, annual report downloads, website screenshots, Excel workbooks with traceable formulas, and optional standalone benchmark reports. Firm-overridable standards control every step.

01

Five-step TNMM workflow

Select your benchmarking standards, upload data in any format, review the proposed screening approach, build a seven-tab Excel workbook, and optionally generate a standalone benchmark report. Each step requires your confirmation before proceeding.

02

Sequential screening with audit trail

Three qualitative screening stages run strictly in order: database assessment from your data, web screening on official company websites, then detailed financials screening from downloaded annual reports. Each stage reduces the comparable set for the next. The search matrix traces every company from initial search to accept or reject.

03

Annual report downloads and website screenshots

The agent navigates company investor relations pages, downloads annual reports as PDF, and takes homepage screenshots of all accepted comparables. Every document is saved to the working papers folder for reviewer traceability.

04

Firm-overridable benchmarking standards

Default standards ship with the plugin. Your firm can override quantitative thresholds, rejection criteria, PLI selection, adjustment formulas, range computation, and the benchmark report playbook. Place your standards file in the firm library and the agent detects and offers it automatically.

05

Traceable Excel workbook

Seven tabs covering search strategy, quantitative screening, search matrix, business descriptions, PLI report, and range analysis. Every computed cell is a formula. Accounting and capital adjustments are fully documented. A reviewer can click any cell and trace the calculation back to the source data.

06

Standalone benchmark report

Generate a reusable working paper with no client or entity names. Follows a playbook structure (customisable per firm) and renders as both an interactive HTML preview and a PDF export. Appendices reproduce the detailed workbook data.

1.4.0

March 2026

Visual Analytics

Automated charts, diagrams, and structured tables bring your documentation to life. Org charts, supply chain flows, DEMPE analyses, and industry graphs are generated directly from your data and rendered in both the interactive preview and PDF exports.

01

Legal entity org charts

Ownership structures render as tree diagrams with percentage labels, country badges, and highlighted entities. Large structures automatically split into a simplified body chart and a full appendix version on a landscape page.

02

Supply chain and transaction flow diagrams

Intercompany flows render as directed graphs showing how goods, services, IP licences, and payments move between group entities. Solid arrows for goods and services, dashed arrows for payment flows. Works for both high-level value chain overviews and per-transaction diagrams.

03

DEMPE analysis tables

Cross-entity DEMPE contributions displayed as structured tables grouped by Development, Enhancement, Maintenance, Protection, and Exploitation. Each entity rated on a seven-point scale from Sole/primary to None.

04

Industry data visualisations

Market size trends, revenue splits, and competitive positioning render as line charts, bar charts, or bubble charts. Data sourced from your files and public information, with clear attribution.

05

Improved functional analysis structure

Functional profiles are now written per profile type first (e.g. Toll Manufacturers, Limited-risk Distributors), then confirmed or adjusted per entity. Reduces repetition when multiple entities share the same characterisation.

06

Markdown formatting in preview and PDF

Bold headings, italic category labels, and paragraph spacing render correctly in both the interactive HTML preview and the PDF export. No more literal stars or missing line breaks.

1.3.0

March 2026

Professional Conduct

IESBA professional ethics and firm-specific conduct standards are built into every interaction. The agent pushes back on unsupported positions, flags risks, and keeps your documentation professionally defensible.

01

IESBA ethics built in

Six core principles from the International Code of Ethics for Professional Accountants (2025 edition) guide every interaction. Includes the 2025 tax planning revisions covering credible basis, the stand-back test, and anti-avoidance awareness.

02

Firm conduct standards

A pre-filled conduct file is created in your workspace at setup, covering output review, data handling, client-facing language, and risk flagging. Sensible defaults work out of the box. Customise to match your firm's policies.

03

Behavioral checkpoints

The agent applies conduct principles at key decision points: method selection, range positioning, conclusions, and risk flagging. It will push back on unsupported positions, decline compliance sign-offs, and flag risks before proceeding.

04

/conduct command

View, edit, or reset your firm's conduct standards directly from Claude Cowork. Add sign-off roles, escalation paths, disclaimer text, or data handling rules without leaving your workflow.

1.2.0

March 2026

Playbook System

Standardize report structures across your firm. Create, inherit, and version playbooks that define how documentation is built for every entity.

01

Folder-based playbooks

Each playbook is a folder with a playbook.md definition and a verbatim/ directory for boilerplate content. Structure and prose live side by side.

02

Template inheritance

Playbooks can extend other playbooks. Start from a firm-wide base, customize per jurisdiction or entity type. One change at the top cascades down.

03

Version control

Every playbook carries a version number. Track changes across reporting periods and ensure consistency across your team.

04

/playbook command

Manage playbooks directly from Claude Cowork. Create, list, inspect, and assign playbooks to entities without leaving your workflow.

1.1.0

March 2026

Memory System

The agent remembers your conventions, entity details, and past decisions across every session. Five memory scopes ensure the right context is always available.

01

Five memory scopes

Personal, firm, group, entity, and deliverable. Each scope captures knowledge at the right level of abstraction for your TP workflow.

02

Persistent context

Memory files survive across sessions. Your firm conventions, entity-specific transfer pricing policies, and methodological choices are always at hand.

03

Automatic memory creation

Running /setup and /prep-local-file creates the right memory folders for your scope. No manual file management required.

04

Dated entries

Each memory entry is timestamped. Track when decisions were made and how your documentation approach has evolved over time.

1.0.0

March 2026
