🌟 Vasilij’s Note
This week I tested all four Claude Code interfaces with the same client workflow—proposal generation with technical requirements extraction. Most consultancies test the wrong interface first, get frustrated, and abandon the tool entirely. The problem isn't Claude Code. It's interface selection. Web version failed on local file access. Desktop app worked immediately. CLI gave me automation I didn't know I needed. Same tool, different contexts, vastly different outcomes.

This Week in Agents | What Changed

  • Anthropic launches Cowork research preview – Claude Max and Pro subscribers can grant Claude direct access to specific local folders to read, edit, and create files across multi-step tasks. Requires user approval for destructive actions, includes prompt injection warnings → File system access transforms Claude from conversational assistant to autonomous workflow executor. Professional services firms can automate report assembly, client deliverable updates, and documentation maintenance—but security posture must address data leakage risks before deployment.

  • Google launches Universal Commerce Protocol (UCP) as open standard – Co-developed with Shopify, Etsy, Wayfair, Target, and Walmart with 20+ endorsements. Enables AI agents to handle complete shopping journeys from discovery through post-purchase without custom integrations. Compatible with Agent2Agent, Agent Payments Protocol, and Model Context Protocol → Retail standardisation reduces N×N integration complexity to single implementation. Professional services consultancies advising retail clients must understand UCP architecture—agentic commerce shifts purchase decisions upstream into conversational interfaces before customers reach traditional storefronts.

  • Anthropic expands into healthcare with HIPAA-ready Claude – Claude for Healthcare and enhanced Claude for Life Sciences connect to CMS coverage data, ICD-10, NPI Registry, ClinicalTrials.gov, PubMed. Novo Nordisk reduced clinical documentation from 10+ weeks to 10 minutes. Announcement came days after OpenAI's ChatGPT Health launch → Healthcare AI market forecast to reach $45.2 billion by 2026. Consultancies serving pharmaceutical, insurance, or healthcare delivery clients face regulatory compliance requirements and data governance frameworks as baseline deployment criteria.

Top Moves - Signal → Impact

Claude Code feature parity creates interface selection complexity

Web interface delivers parallel repository execution (unique capability) but limited to 60% overall features, no local file access, no MCP integration. Desktop app provides 75% features with local files and MCP but bash-only shell and worktree issues. IDE offers 85% features with native diffs but requires version-matching between components. CLI gives 100% features with full automation but high learning curve and no default visual diffs.

→ Multi-client consultancies requiring concurrent project work forced into Web despite missing local file access and system integrations. Agent workflow architecture constrained by interface limitations, not business requirements.

Calculate rollout efficiency: Desktop 5 min × 20 staff × 2 (troubleshooting) = 200 minutes (3.3 hours) vs CLI 10 min × 20 × 3 (support) = 600 minutes (10 hours). Interface selection costs 3x in deployment time.

GitHub Copilot Enterprise adds repository-wide context

GitHub ships natural language code search across entire organization repositories, PR summaries with automated review suggestions, and fine-tuning on private codebases. 55% of developers report shipping code faster with Copilot Enterprise vs standalone Copilot.

→ Consultancies managing 50+ client repositories gain unified search across engagement history. Technical debt documentation becomes searchable ("find all instances where we used deprecated API pattern X"). Code review time reduced 30-40% through AI-generated PR summaries highlighting security risks and breaking changes. Reduces dependency on senior developers for all code reviews.

Workflow automation platforms add agent orchestration

n8n, Make, and Zapier announce native agent nodes enabling multi-step autonomous workflows with approval gates. Agents can now trigger based on conditions, wait for human approval at specified checkpoints, and continue execution autonomously.

→ Mid-market consultancies (50-250 staff) previously requiring custom development to chain AI capabilities can now build agent workflows through low-code interfaces. Client onboarding automation (data collection → analysis → proposal draft → partner review → delivery) becomes accessible without engineering team. Reduces custom integration costs from £15,000-25,000 to under £2,000.

Maker Note | What I built this week

This week I mapped three client onboarding workflows across Claude Code's four interfaces.

Decision: Desktop for team rollout (lowest friction, highest stability), CLI for my automation library (full features, scripting support), Web for client-site testing (zero setup, works on locked-down devices). Each interface solves different problems—trying to use one for everything creates unnecessary friction and adoption failure.

I break down what each interface actually does, compare them across twelve key factors, and show you which one fits your workflow.

Operator’s Picks | Tools To Try

Claude Code Desktop App – Use for team rollout when terminal intimidates non-technical staff.

Standout: GUI throughout, five-minute setup, highest stability across interfaces.

Caveat: bash-only shell (won't work if team uses zsh/fish), worktree isolation issues requiring manual cleanup, context compacting in long sessions.

Claude Code CLI – Use for automation and power users comfortable with terminal.

Standout: 100% feature completeness, fastest updates (new features land here weeks before other interfaces), full scripting support, 200k context window.

Caveat: high learning curve blocks non-technical adoption, no default visual diffs (requires external tool configuration), ephemeral sessions, repetitive permission prompts for file operations.

Claude Code Web – Use for zero-setup testing and client-site work where installation blocked.

Standout: instant access, mobile support via iOS/Android apps, parallel repository execution (only interface supporting this), fast updates.

Caveat: 60% features vs other interfaces, no local files, no MCP integration, 500MB repo size limit, GitHub connection mandatory, cloud execution only.

Deep Dive | Thesis & Playbook

Claude Code fixes the isolated Claude Projects problem through shared context and automatic handoffs between agents. But four different interfaces create adoption barriers when firms test the wrong one first.

On Paper

  • Four interfaces, same underlying system.

    Web: instant setup, cloud execution, parallel repos, 60% features.

    Desktop: 5-minute setup, GUI interaction, local files, MCP support, 75% features, highest stability.

    IDE: 15-minute setup (extension + CLI), native diffs, error sharing, 85% features.

    CLI: 10-minute setup, terminal-based, full automation, 100% features, fastest updates.

  • Open standard enables portability. Skills work across interfaces. Enterprise admins control provisioning org-wide. API supports up to 8 skills per request with versioning.

In Practice

  • Setup reality varies dramatically. Web instant, Desktop 5 minutes, CLI 10 minutes, IDE 15 minutes with two components requiring version matching. Learning curve: Web and Desktop low, IDE medium, CLI high.

  • Feature fragmentation forces interface selection based on workflow constraints. Need parallel repos? Web only. Need MCP integration? Desktop/IDE/CLI. Need full automation? CLI only. Need visual diffs? IDE native, others require configuration.

  • Desktop limitations: bash-only shell breaks teams using zsh/fish. Worktree isolation issues need manual cleanup. IDE limitations: extension-CLI version mismatches cause breakage. Performance overhead on large codebases. CLI limitations: terminal intimidation blocks non-technical staff. No persistence between sessions.

  • Adoption friction: 2-4 weeks before consistent usage across teams. Edge cases require manual intervention 10-20% initially. Context compacting affects all interfaces in long sessions.

Issues / Backlash

  • Interface confusion causing adoption failures. Teams test CLI first because "that's what developers use," hit learning curve, abandon tool before trying Desktop. Feature expectations misaligned—teams discover limitations after rollout begins.

  • Web client's 500MB repository limit and GitHub-only requirement blocks use cases. No local file access eliminates entire workflow categories. Desktop's bash limitation frustrates 40% of development teams using alternative shells.

  • Security gaps persist across interfaces. Prompt injection risks in file uploads. Data governance complexity when skills inherit user permissions. Shadow AI proliferation as teams share interface access outside approved channels.

My Take (What to do)

  • Startup (15-40 staff): Start with Desktop app—5-minute setup, GUI throughout, lowest learning curve. Gets team productive immediately without terminal training. Add Web access for quick testing on client sites. Hold CLI until you have specific automation requirements worth the learning investment (calculate: will automation save more hours annually than learning curve costs?). Don't force everyone onto one interface.

    Calculate rollout cost: 5 min × team size × 2 (troubleshooting factor) = total hours. For 20-person team, that's 3.3 hours vs 10 hours for CLI.

  • SMB (50-120 staff): Desktop as default for general adoption. Web for project managers and non-technical staff. CLI for senior consultants who already use terminal—let them build automation library for common workflows. IDE for developers doing code reviews.

    Establish interface selection policy: which roles use which interfaces based on technical capability and workflow needs. Track adoption patterns monthly, identify winning workflows, standardise.

  • Enterprise (150-250 staff): Formal interface selection policy required before rollout. Desktop as default for business users. CLI for technical team and automation workflows. IDE for developers refusing to leave editor. Web as fallback for restricted environments. Require business case for CLI adoption—automation ROI must justify learning curve investment (calculate hours saved vs hours spent on training and support).

    Consider workflow-specific recommendations: proposal generation (Desktop), code reviews (IDE), client onboarding automation (CLI), on-site consulting (Web). Monitor interface usage, retire underutilised access patterns.

How to Try (15-minute path)

  1. Go to claude.ai/code, connect GitHub account, select one test repository. Test file navigation and simple code generation request. Observe parallel repo capability if you have multiple projects open. (5 min)

  2. Install Desktop app (claude.ai/download), open local project folder, run same workflow from step 1. Compare experience—note local file access, GUI interaction model, project switching mechanism. Check if bash-only shell limitation affects your workflows. (5 min)

  3. Document decision matrix: Did you need local files? MCP integration for connecting to your internal systems? Parallel repo work? Full automation capabilities? Match requirements to interface features. Calculate setup time across team size for chosen interface. (3 min)

  4. If terminal-comfortable and automation critical to workflows, test CLI with claude-code command in one directory. Note feature completeness difference and scripting possibilities. (2 min)

    Success metric: Clear decision on which interface(s) your team needs based on actual workflow requirements and technical capability, not assumptions or "what developers should use." Documented rollout plan with calculated hours and interface-to-role mapping.
