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 | $0.00079 | $0.00961 |
| Opus 5 | $0.00039 | $0.00481 |
| Sonnet 5 | $0.00016 | $0.00192 |
| Haiku 4.5 | $0.00008 | $0.00096 |
Grade A, and why
related-skills-surfacer 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to use
Suggest community skills matching recent task — once, non-intrusively; strong matches only.
Preconditions
| Input | If missing |
|---|---|
| Hub engagement profile | Offer practice-setup |
| Task context or user query | Ask what they were doing |
Provisional mode
Notifications set to none in profile — skill off.
Trust spine
Structured-aggregation; frequency limit via surfaced.json; no nag on weak matches.
Workflow
The community might have built the thing you're about to build. This skill notices and mentions it — once, briefly, non-annoyingly.
How it runs
This skill surfaces related community skills after a task. It can be invoked directly by the user ("what else is out there for X?") or wired into other plugins via a Stop hook — the hook-based pattern requires each sibling plugin to declare a Stop hook that calls this skill, which is not wired by default. Without the hook wiring, invoke it directly.
Other plugins can include a light check at the end of a task:
"The strategy-builder-hub found a community skill that might help with this kind of thing: [name] — [one-line]. Want to take a look?"
Load context
~/.claude/plugins/config/claude-for-strategy/strategy-builder-hub/CLAUDE.md → engagement profile, installed skills (don't suggest what's already installed).
Registry cache from registry-browser.
The match
Given a task description (what the user was just doing), find registry skills that match:
- Keyword overlap between the task and skill descriptions
- Engagement profile fit (don't suggest PMO skills to a corporate strategist who didn't ask)
- Not already installed
Threshold: Only surface if the match is strong. Weak matches are noise. Better to surface nothing than to annoy.
Output
If strong match:
The community has a skill for this: [name] from [registry] — "[description]".
/strategy-builder-hub:skill-installer [name]to try it.
If no strong match: silent. No output. Don't announce "I found nothing."
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.

related-skills-surfacer is a skill published in the GitHub repository daddia/claude-for-strategy (2 stars, last pushed 2mo ago), licensed MIT. It adds 79 tokens to every session and 961 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
