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 B, and why

auto-updater scanned grade B with 1 finding 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 7d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

When to use

Check installed community skills for updates; show diff; apply only after explicit human approval.

Preconditions

Input If missing
Hub engagement profile with installed list Offer practice-setup
User approval for each apply Never auto-apply

Provisional mode

N/A — updates always require diff review.

Trust spine

Governance-tracking; fail-closed on skills-qa regression; security-surface diffs force human approval.

Workflow

Community skills improve. This skill notices when, shows you what changed, and applies updates only with your explicit approval.

Trust posture

Installed skills are code running inside your privileged strategy environment. An upstream repository can be compromised, transferred to a new owner, or simply change behavior in ways you don't want. This skill is designed so that no update is ever applied without you reading the diff and approving it. That's not a preference — it's the design.

Load context

  • ~/.claude/plugins/config/claude-for-strategy/strategy-builder-hub/CLAUDE.md → installed skills summary, update preferences (notify / manual).
  • ~/.claude/plugins/config/claude-for-strategy/strategy-builder-hub/install-log.yaml → authoritative pinned_sha per skill (see skill-installer/references/install-log-schema.md). Prefer the latest install or update entry over the CLAUDE.md table when they disagree.

Workflow

Step 1: Check each installed skill

For each skill in the installed list:

  • Read pinned_sha from the latest install or update entry in install-log.yaml for that skill
  • Fetch the current commit SHA from the source registry (the exact commit, not a tag or branch head — tags are mutable and can be retroactively rewritten by the publisher; only commit SHAs are immutable)
  • Compare to the pinned SHA from install time
  • If different: update available

Step 2: Diff and trust review

For each update, show the full diff:

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.
