pos: Skill for Claude Code

.claude/skills/vault-scaffolder/SKILL.md

vault-scaffolder is a skill for Claude Code from xcota/pos. It costs 29 tokens per session (5,517 once invoked), scanned A, original, MIT.

A personalisation tool for a Personal OS workspace, using a completed `profile.yaml` file as the person's profile. It fills in identity, goals, and operating files in an existing workspace.

In plain words
What is it for?
Use it after creating a Svoboda profile to personalise the Personal OS, write context and operational files, and add profile-specific guidance to the workspace.
Why use it?
It avoids manually copying profile information into many workspace files. It also checks that the required profiling step has already been completed.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is xcota/pos's own configuration. It tells Claude Code how to work on pos itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pos configures →

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 →

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.

Security

Grade A, and why

vault-scaffolder 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 10d 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.

/vault-scaffolder — Personalize the Personal OS (in-place)

Takes a completed svoboda profile.yaml (v3.2 schema) and personalizes the Personal OS in the current workspace. Overwrites the blank onboarding CLAUDE.md, writes context/identity.md, context/goals.md, the self-entity, and the operational layer, and appends profile-specific anti-patterns to the shipped corpus.

Assumes the engine is already present. Skills (.claude/skills/), templates (_templates/), context/scoring-gate.md, AND the shipped engine corpus — context/anti-patterns.md, anti-patterns-index.md, context/learned.md, learned-index.md, rules/*.md — all ship with the starter repo. The scaffolder personalizes content; it does NOT re-scaffold skills, templates, or the AP/L corpus. It NEVER regenerates anti-patterns.md or learned.md — it appends to them.

Reads the v3.2 nested schema directly (see contract below). It does not require the profiler to flatten anything.

Invocation

/vault-scaffolder {subject_id}

Input

  1. Required: {subject_id} argument
  2. Read memory/svoboda/{subject_id}/profile.yaml
  3. If missing → error: "Run /svoboda-profiler {subject_id} first"

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.
