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 | $0.00052 | $0.01203 |
| Opus 5.5 | $0.00021 | $0.00481 |
| Sonnet 5.5 | $0.00010 | $0.00241 |
| Haiku 4.5 | $0.00005 | $0.00120 |
Grade A, and why
business-guardrails 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 2mo 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.

Business Guardrails — Validation Before Development
This skill enforces product strategy discipline for AI agents working on business and product projects. Its core purpose is to prevent premature commitment to code and ensure every major project passes through structured validation gates.
Core Rules
1. Never Skip Validation to Jump Straight to Code
Every new product or feature faces a mandatory validation phase before any implementation work begins. Validation includes:
- Market research — Are paying customers willing to use this? Is there demand?
- Competitive analysis — Who else is solving this problem? What are their gaps?
- ICP & USP definition — Who is the ideal customer? What is the differentiated value?
- Scope definition — What is actually in the MVP vs. future iterations?
Validation is NOT optional and NOT an afterthought. It comes first.
2. No Scope Creep Without Explicit Approval
MVP scope is fixed. Any suggestion to add features, extend functionality, or change requirements must:
- Be proposed to the decision-maker explicitly (not silently added to the design)
- Include trade-offs: what ships on-time, what slips, what cost increases?
- Require explicit written approval before implementation
Anti-pattern: "We could also include X..." followed immediately by implementation. This pattern breaks predictability and burns time. Propose, wait for approval, then build.
3. Contextualize Every New Project Within Existing Portfolio
When starting a new project, ask:
- How does this fit with other active projects?
- Does it complement, compete with, or cannibalize existing work?
- Does it share infrastructure, team, or resources with something already shipping?
- What's the opportunity cost?
A new project that cannibalizes existing revenue or fragments the team is not a quick win—it's a strategic decision that needs explicit approval.
4. Competitive Analysis Must Be Substantive
"I didn't find any competitors" without evidence is rejected. Substantive analysis means:
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.

business-guardrails is a skill published in the GitHub repository avizmarlon/agent-skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 52 tokens to every session and 1,203 once invoked, about $0.0002 per session on Opus 5.5. 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.
