Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00048 | $0.00942 |
| Opus 5.5 | $0.00019 | $0.00377 |
| Sonnet 5.5 | $0.00010 | $0.00188 |
| Haiku 4.5 | $0.00005 | $0.00094 |
Grade A, and why
macos-development-vm-workflow 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.
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.

macOS Development VM Workflow
Purpose
Prepare a reproducible macOS guest while keeping restore images, identity, disks, saved state, clones, integrations, and exported evidence as separate lifecycle artifacts.
When To Use
- Use for clean macOS releases, installers, updates, signing, entitlements, quarantine, Gatekeeper, XProtect, TCC, SIP-enabled behavior, LaunchServices, and native persistence.
- Use after custom host implementation or with an existing documented VM manager.
- Use for development guests and benign security fixtures; security controls still require
prepare-isolated-analysis-labfor untrusted execution.
Single-Path Workflow
- Consume the virtualization shape record.
- Verify Apple silicon host, host build, current framework/tool docs, restore-image support, guest build, storage, memory, and installation time budget.
- Record each artifact using macOS VM artifact lifecycle: restore image, hardware model, machine identifier, auxiliary storage, disk, bundle metadata, saved state, clone, and evidence export.
- Build or verify a compatible Mac platform, boot loader, disk, CPU/memory, graphics/display, network, input, and entropy configuration; validate before installation or boot.
- Install with the documented restore-image flow and preserve exact progress/errors. Do not invent or duplicate Mac identity artifacts.
- Configure guest purpose and integrations. Directory sharing, clipboard, audio input, USB, Apple account, iCloud, developer account, signing identities, browser profiles, and network are opt-in.
- Establish a clean baseline, then choose named development/update checkpoints or disposable clones using only lifecycle operations the selected tool actually supports.
- Validate guest build/architecture, SIP and relevant controls, network/shares, reboot, toolchain, target behavior, evidence export, and reset.
- Record VM artifacts and physical-hardware gaps that may affect the conclusion.
What ships with it
3 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.
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.

macos-development-vm-workflow is a skill published in the GitHub repository gaelic-ghost/socket (7 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 48 tokens to every session and 942 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
Other skills, from other repositories
craft
Use when a product idea is still vague and needs to become a clear definition of what to build — "let's craft an app like X", "help me define what I actually want", "clarify this idea before we plan it". Also use before planning or implementation when requirements, UX, domain behaviour, or technical preferences have…
pipeline
Use when the user asks to take a substantial feature from an initial idea through implementation in one mostly autonomous run.
turbo-pipeline
Use when the user wants a feature built end to end after answering one round of questions and then being left alone — "turbo", "ask me once, then just build it", "I'll answer up front, don't come back to me", "decide the rest yourself". Not for a run that wants a spec approval and no tests (superb:fast-pipeline), one…
pipeline-auto
Use when the user wants a substantial feature taken from idea through implementation in one run with as little interruption as possible ("just build it", "don't keep asking me"), or when controlling such a run and a worker question, quorum responses, the drift budget, a human decision, a review class or a completeness…
bug-fix
Use when a bug, regression, or unexpected behaviour is reported and the user wants it fixed end to end — "why is X broken", "this stopped working after Y", "fix this crash". Also use when a symptom is known but its cause is not. Not for building new behaviour, and not for a change whose cause is already proven.
fast-pipeline
Use when the user wants a feature built quickly with low token cost and few interruptions, approves a spec once, and says no automated tests should be written because they will test it manually — "fast pipeline", "go fast, no tests, I'll test it myself", "don't keep asking me". Not for a run that should write or keep…
