3p

3p is a skill for Claude Code from patrickjaja/claude-desktop-extra. It costs 143 tokens per session (1,987 once invoked), scanned A, original, MIT.

Reference material for running a managed or third-party Claude Desktop deployment on Linux. In this setup, Claude Desktop can use an organization-controlled configuration and a non-Anthropic model service.

In plain words
What is it for?
Use it to configure or troubleshoot the Linux managed settings file, separate third-party user data, hidden interface elements, Cowork behavior, and related hardcoded paths.
Why use it?
Managed deployments have different configuration files, user-data locations, and visible app behavior than a normal installation. The reference explains those differences and notes version-specific details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

3p scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

3p / enterprise / inference-gateway deployment on Linux

"3p" = third-party / managed deployment: Claude Desktop pointed at a non-Anthropic inference backend (Bedrock, Vertex, Azure, or a self-hosted gateway like LiteLLM) and/or an MDM-managed config. On Linux it is driven by /etc/claude-desktop/managed-settings.json. Minified names below are version-specific (they churn every release - see /linux); anchor on stable strings. Verified against v1.14271.0.

managed-settings.json (/etc/claude-desktop/managed-settings.json)

The official Linux build reads /etc/claude-desktop/managed-settings.json natively - it ships a Linux managed-config reader, so we no longer patch the win32-registry/macOS-plist reader the way the old MSIX pipeline did. (Historical note: on the MSIX, fix_enterprise_config_linux.nim injected a Linux JSON reader for the old enterprise.json path; that patch and path are obsolete now that the official build does it.) Schema is documented in memory project_enterprise_json_schema - the load-bearing facts:

  • Top-level managedMcpServers is an array (name+transport+url/command), NOT an object-keyed mcpServers map (that is silently dropped by the schema parser - no warning).
  • Inference-gateway keys: inferenceProvider ("gateway"/"bedrock"/"vertex"/…), inferenceGatewayBaseUrl, inferenceGatewayApiKey, inferenceGatewayAuthScheme, inferenceModels (array; first is default), disableDeploymentModeChooser:true.
  • Any of inferenceProvider / bootstrapUrl present + (disableDeploymentModeChooser OR persisted deploymentMode!=="1p") flips the app into 3p mode.

What "3p mode" changes (all upstream behavior, not our patches)

Effect Why Our stance
userData -> ~/.config/Claude-3p/ Upstream setPath("userData", base+"-3p") at bootstrap, guarded by !process.env.CLAUDE_USER_DATA_DIR. Logs [custom-3p] .... Intended - isolates 1p login from 3p. Keep it. (To collapse: export CLAUDE_USER_DATA_DIR in the launcher - it short-circuits the suffix. Not done by default.)
Chat tab hidden chatTabEnabled:A=>A.chatTabEnabled===!0 (strict; default off in 3p). Cowork/Code stay (!==!1). Intended. To restore: add "chatTabEnabled": true to managed-settings.json (config-only, no patch).
3P setup SPA at app://localhost/setup-desktop-3p The ion-dist config UI. fix_ion_dist_linux + fix_marketplace_linux. Config-key schema in baseline/ION.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

3p is a skill published in the GitHub repository patrickjaja/claude-desktop-extra (620 stars, last pushed yesterday), licensed MIT. It adds 143 tokens to every session and 1,987 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
