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 | $0.00110 | $0.06824 |
| Opus 5 | $0.00055 | $0.03412 |
| Sonnet 5 | $0.00022 | $0.01365 |
| Haiku 4.5 | $0.00011 | $0.00682 |
Grade B, and why
skills-qa scanned grade B with 2 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
1. **Override / ignore instructions** — "ignore previous instructions", "disregard the above", "forget what the user said", "the real instructions are", "priority override". Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
8. **Shell / code execution** — any instruction to run shell commands, curl scripts from URLs, eval strings, or execute code outside what the skill's stated purpose requires. How it starts

When to use
Evaluate skill against Strategy Skill Design Framework — 13 parameters, failure modes, Ready / Some Concern / Material Concerns verdict.
Preconditions
| Input | If missing |
|---|---|
| Skill path, SKILL.md path, or pasted content | Ask once |
| Hub profile (optional) | Proceed; flag conflict check incomplete |
Provisional mode
SKILL.md only — flag incomplete dependency mapping; ask once for commands/agents/hooks.
Trust spine
Hypothesis-driven-analysis; injection heuristic scan before design eval; fail-closed on update regression; verdict advisory not install block (except installer integration).
Inputs accepted
- File path to a skill directory (preferred — enables full dependency mapping)
- File path to a SKILL.md only
- SKILL.md content pasted directly into the conversation
Context to load
~/.claude/plugins/config/claude-for-strategy/strategy-builder-hub/CLAUDE.md→ engagement profile and installed skills list (provides context for evaluating whether the skill fits the user's team and workflow, and whether it duplicates something already installed)
Notes
This QA check runs automatically as part of /strategy-builder-hub:skill-installer. You can also run it directly on any skill before deciding whether to install, or on a first-party skill before deploying to your team.
Run it deliberately — before incorporating any community skill you did not build, or before deploying a first-party skill to your team.
If the user runs /strategy-builder-hub:skill-installer and then asks "should I trust this?" or "is this well-designed?", route to this skill rather than answering inline.
Purpose
Anyone can build a skill. This one checks whether it was built well before it touches your workflows.
Evaluates any skill against the Strategy Skill Design Framework: nine design-parameter checks (Parameters 1–9 — audience through escalation logic), plus trust-surface review (Parameter 10), freshness (11), schema (12), and conflicts (13). Parameter 7 embeds the three strategy-specific failure modes. Step 1.5 runs the prompt-injection heuristic scan before the nine-parameter evaluation. Produces a dependency map and a clear verdict. Works for community skills from registries and first-party skills your team is building or deploying.
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.

skills-qa is a skill published in the GitHub repository daddia/claude-for-strategy (2 stars, last pushed 2mo ago), licensed MIT. It adds 110 tokens to every session and 6,824 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
