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 | $0.00077 | $0.02201 |
| Opus 5 | $0.00039 | $0.01100 |
| Sonnet 5 | $0.00015 | $0.00440 |
| Haiku 4.5 | $0.00008 | $0.00220 |
Grade A, and why
swift-package-testing-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 yesterday.
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.

Swift Package Testing Workflow
Purpose
Use this skill as the primary execution workflow for test-focused work in existing Swift package components. Keep it focused on Swift Testing, XCTest holdouts, code coverage, .xctestplan handoff conditions, async-test guidance, semantic accessibility-test boundaries, performance-sensitive package workload profiling, filters, retries, fixtures, and package-level test diagnosis. scripts/run-workflow.fsx resolves the nearest package root and plans the test surface without classifying the containing repository.
When To Use
- Use this skill for running, diagnosing, organizing, or evolving tests in an existing Swift package repo.
- Use this skill for Swift Testing-first package work, XCTest holdouts, async-test design, semantic accessibility-test boundaries, and test-fixture organization.
- Use this skill for package-level
.xctestplanexecution when the package surface needs Xcode test-plan follow-through. - Use this skill when the request is about test selection, filtering, retries, failures, flaky tests, or test-only Debug/Release validation.
- Use this skill when the request is about package-first performance-sensitive testing, signpost placement, Release workload harnesses, or profiling-ready package test design for Audio, Metal, MLX, local AI, streaming, or other Apple silicon-sensitive workloads.
- Do not use this skill for broad manifest edits, dependency work, package resources, package-extension design, or ordinary build and run work.
- Do not use this skill for brand-new package bootstrap from nothing.
- Do not use this skill for repo-guidance alignment in an existing package repo.
- Do not use this skill as the default path for Xcode workspace, scheme, preview, simulator, or navigator-driven work.
- Recommend
swift-package-build-run-workflowwhen the request is primarily about ordinary package build/run, manifest, dependency, resource, or Metal-distribution work. - Recommend
swift-package-extension-workflowwhen trait matrices, macro/plugin test shape, or generated-source validation is the primary concern. - Recommend
bootstrap-xcode-workspace --operation create --component-kind librarywhen the package repo does not exist yet. - Recommend root workspace
just alignwhen product guidance needs to be refreshed. - Recommend
xcode-testing-workflowwhen test work depends on active Xcode workspace state, navigator diagnostics, simulator or device flows, XCUITest, runtime accessibility verification, or Xcode-native test plans and test execution. - Recommend
apple-ui-accessibility-workflowwhen the request is primarily about accessibility semantics or review rather than package-side testing strategy. - Recommend
xcode-build-run-workflowwhen package test work crosses into guarded mutation, file membership, or other Xcode-managed project-integrity work. - Recommend
explore-apple-swift-docswhen the user needs Apple or Swift docs exploration before implementation or test 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.

swift-package-testing-workflow is a skill published in the GitHub repository gaelic-ghost/socket (7 stars, last pushed 9d ago), licensed Apache-2.0. It adds 77 tokens to every session and 2,201 once invoked, about $0.0004 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 2026-09-03.
Other skills, from other repositories
pipeline
Use when the user wants a feature idea taken end-to-end in one autonomous run — phrases like "run the whole pipeline", "take this feature from idea to finished branch", "brainstorm then build it autonomously", "do everything from idea to merged", "implement all phases without stopping". Triggers when they want…
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…
chief-financial-officer
Owns the financial position: planning, budgeting, forecasting, unit economics, cash, and the numbers the business is run and reported on. Use this to build or challenge a budget, model a decision's financial consequence, assess unit economics or runway, evaluate an investment or spend request, set financial controls…
chief-strategy-officer
Owns where the business plays and how it wins over a multi-year horizon — portfolio choices, corporate development, strategic partnerships, and planning under uncertainty. Use this for a decision about which markets or businesses to be in, whether to build, buy, or partner, how to allocate capital across business…
business-growth-consultant
Finds the single constraint currently limiting a business's growth and the highest-leverage moves against it, rather than producing a list of everything that could be improved. Use this when growth has stalled or slowed, when deciding where to spend limited time or budget, when revenue rises but profit does not, when…
ceo-advisor
Pressure-tests a decision, plan, or idea before it is committed to — surfacing the assumption it rests on, the case against it, and what would have to be true for it to work. Use this when weighing options, when a plan needs challenging before commitment, when you have already decided and want a genuine gut check…
