What is windows-dev-process-cleanup?

A Windows troubleshooting guide for auditing and safely cleaning leftover development processes and UWP background tasks. UWP is Windows' platform for packaged apps.

Use it to audit process trees, preview cleanup plans, and remove narrowly selected stale development or app background processes on Windows.

It helps investigate buildup from tools such as npm, Playwright workers, development servers, IDE services, Phone Link, Dolby Access, and backgroundTaskHost.exe.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00124	$0.00785
Opus 5.5	$0.00050	$0.00314
Sonnet 5.5	$0.00025	$0.00157
Haiku 4.5	$0.00012	$0.00078

Security

Grade A, and why

windows-dev-process-cleanup 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 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/audit-dev-processes.ps1, scripts/audit-uwp-backgroundtasks.ps1, tests/audit-scripts.test.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Windows Dev Process Cleanup

Audit first and use the narrowest profile. Requires Windows and PowerShell 7; replace <skill-dir> with the loaded skill directory.

Workflow

Audit without side effects:

pwsh -NoLogo -NoProfile -File "<skill-dir>/scripts/audit-dev-processes.ps1" -Mode audit -AsJson
pwsh -NoLogo -NoProfile -File "<skill-dir>/scripts/audit-uwp-backgroundtasks.ps1" -Mode audit -AsJson

Treat blocked, mixed_tree, unknown, identity-missing, protected members, and audit_status: failed as manual review.
Select one profile:

Dev: safe, playwright-mcp, codex-playwright-safe, safe-plus-codex-playwright, or workspace-dev-server with an existing -WorkspacePath.
UWP: phone-link-background or dolby-backgroundtask. Dolby cleanup terminates only matching backgroundTaskHost instances.

Preview the exact plan before cleanup:

pwsh -NoLogo -NoProfile -File "<skill-dir>/scripts/audit-dev-processes.ps1" -Mode cleanup -Profile codex-playwright-safe -StaleMinutes 45 -WhatIf -AsJson
pwsh -NoLogo -NoProfile -File "<skill-dir>/scripts/audit-uwp-backgroundtasks.ps1" -Mode cleanup -Profile dolby-backgroundtask -WhatIf -AsJson

Run without -WhatIf only after an explicit cleanup request and an unblocked plan. The scripts recheck identity and affected members; drift fails the precondition.

Phone Link 2.0 Change

-DisablePhoneLinkBackground is deprecated and fails closed. It never writes the registry. Microsoft documents the supported per-app control in Windows Settings under System > Power & battery > Battery usage > Manage background activity. See migration-2.0.md.

Output Contract

Report normalized inputs, affected PIDs/fingerprints, roles/protection, blocked reasons, plan_id, target counts, preconditions, command status, and per-member outcomes. A zero taskkill exit code is not proof of termination.

Process termination is irreversible. Report exports are local files. No registry rollback exists because version 2.0 performs no registry mutation.

What ships with it

27 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
