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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00056 | $0.00216 |
| Opus 5.5 | $0.00022 | $0.00086 |
| Sonnet 5.5 | $0.00011 | $0.00043 |
| Haiku 4.5 | $0.00006 | $0.00022 |
Grade A, and why
xcodebuildmcp 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.
What it actually says
xcodebuildmcp
This skill wraps an MCP server behind a local CLI so pi agent can use it without MCP support.
Setup
Run once:
cd {baseDir}
npm install
Usage
Use --output json for agent workflows.
{baseDir}/xcodebuildmcp.sh --help
{baseDir}/xcodebuildmcp.sh --output json <command> [flags]
Regenerating the CLI
If the MCP server adds/removes tools, regenerate the CLI from its embedded metadata:
cd {baseDir}
npx mcporter generate-cli --from ./xcodebuildmcp.ts
What ships with it
4 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.

xcodebuildmcp is a skill published in the GitHub repository w-winter/dot314 (139 stars, last pushed 3d ago), licensed MIT. It adds 56 tokens to every session and 216 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 2026-08-30.
