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 | $0.00054 | $0.01022 |
| Opus 5.5 | $0.00022 | $0.00409 |
| Sonnet 5.5 | $0.00011 | $0.00204 |
| Haiku 4.5 | $0.00005 | $0.00102 |
Grade A, and why
linux-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.

Linux Development VM Workflow
Purpose
Prepare one persistent Linux development environment whose lifecycle, host integrations, provenance, validation, and reset path are explicit.
When To Use
-
Do not use this workflow to build, test, package, or deploy a Gale-owned Swift product service. Its local path is native macOS with Homebrew services, and GitHub Actions owns every cloud Linux artifact and deployment. Keep this workflow for explicit VM fidelity, distro, kernel, or unrelated repository work.
-
Use for distro-specific builds, services, systemd or another init system, repeated shells, full-system tests, custom kernels, EFI boot, or GUI Linux.
-
Use to decide between
container machine, Lima/Colima, and a full VM by required fidelity rather than product preference. -
Do not use for a single portable application image; use the container owner skills.
Single-Path Workflow
- Consume the virtualization shape record.
- Discover current official documentation and installed versions/help for every candidate tool.
- Select the smallest adequate path:
container machine: OCI-backed persistent Linux, init/services, repeated interactive development- Lima/Colima adapter: tool-managed Linux environment when its documented lifecycle and integration match the task
- full Virtualization framework VM: custom boot/kernel/disk/devices, full-system or GUI behavior, or tighter integration control
- Record distro/image/kernel provenance, architecture, CPU, memory, disks, network, mounts, sockets, credentials, and expected lifetime.
- Keep host home, writeable shares, SSH agent, credentials, clipboard, and unrestricted network opt-in. A development convenience is not a security boundary.
- Configure Linux or EFI boot, virtio devices, provisioning, services, Rosetta, and nested virtualization only when the selected path and current host/guest support them.
- Define create, provision, start, shell/SSH, stop, update, checkpoint/reset, export, and remove semantics using the selected tool's vocabulary.
- Validate the distro matrix: identity, architecture, toolchain, build, tests, services, filesystem semantics, network, reboot persistence, and cleanup.
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.

linux-development-vm-workflow is a skill published in the GitHub repository gaelic-ghost/socket (9 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 54 tokens to every session and 1,022 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.
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…
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…
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…
