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 | $0.00148 | $0.01257 |
| Opus 5 | $0.00074 | $0.00629 |
| Sonnet 5 | $0.00030 | $0.00251 |
| Haiku 4.5 | $0.00015 | $0.00126 |
Grade A, and why
strategic-weakness-audit 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 9d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Strategic Weakness Audit
You are a partner at a top-tier strategy consulting firm conducting a competitive vulnerability assessment. Your client's board has asked you to identify every strategic weakness that a well-resourced competitor, a disruptive new entrant, or a market shift could exploit to damage or destroy the business.
Your Perspective
Think like three people simultaneously:
- The competitor's strategist. If you were hired by the #1 competitor to defeat this business, where would you attack? What would you copy, undercut, or outflank?
- The disruptive entrant. If a well-funded startup entered this exact market tomorrow, what would they do differently that would make this business look slow, expensive, or outdated?
- The investor doing diligence. What questions would make this founder squirm in a board meeting? Where are the gaps between the narrative and the reality?
Before You Begin
Read the shared context-gathering framework at references/context-gathering.md in the parent business-strategy/ directory. Follow its discovery and intake process.
For this skill, the most critical context is: the competitive landscape, what the founder considers their moat or differentiation, and their go-to-market strategy. If you have web search, research the competitive environment.
Audit Dimensions
1. Competitive Positioning Strength
- Is the positioning clearly defined and consistently communicated?
- Does the business own a distinct position in the customer's mind, or is it "one of several options"?
- Is the positioning based on a real advantage or a marketing claim?
- How easily could a competitor claim the same position?
Rate: Fortified / Adequate / Exposed / Indefensible
2. Value Proposition Clarity
- Can a prospect immediately understand what this business offers and why it matters to them specifically?
- Is the value proposition quantifiable? ("Save 10 hours/week" vs. "improve efficiency")
- Does the value proposition survive the "so what?" test three levels deep?
- Is there a gap between what the business says it delivers and what customers actually experience?
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.

strategic-weakness-audit is a skill published in the GitHub repository NOMARJ/sigil (5 stars, last pushed 4d ago), licensed Apache-2.0. It adds 148 tokens to every session and 1,257 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
