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 | $0.00029 | $0.00771 |
| Opus 5 | $0.00015 | $0.00385 |
| Sonnet 5 | $0.00006 | $0.00154 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
skill-product-solution-blueprint 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 5d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Solution Blueprinting
1. Objective
To translate abstract "Vision" into concrete "Requirements" without writing code. This skill powers the Solution Architect (p04) agent.
2. Text-Based UX Flows (The "Skeleton")
Constraint: Do NOT use Mermaid graphs for detailed logical flows. Use text lists.
Template
Use the Official Template for the full structure.
Syntax Example
### Flow 1: [User Story Name]
- **Size:** M (60h) | **LLM Friendly:** 0.8
1. User [Action] on [Page/Component].
- *System:* [Validates/Checks/Loads].
- *Error Path:* If [Condition], show [Error Message].
2. User sees [Result].
3. Business Case (Enhanced ROI)
Logic Locker (CRITICAL)
[!IMPORTANT] FORBIDDEN ACTION: You are strictly forbidden from calculating ROI/NPV manually. You MUST first list all User Stories with sizes + friendliness, then run the script.
Protocol
- Estimate: For each user story, assign a Size (XS, S, M, L, XL) and LLM Friendliness (0.0 - 1.0).
- Prepare: Create a temp JSON file in
docs/product/(e.g.,docs/product/stories.json):{ "stories": [ { "name": "Login", "size": "S", "llm_friendly": 0.9 }, { "name": "Complex Dashboard", "size": "L", "llm_friendly": 0.3 } ] } - Execute:
# Usage: python3 [skill_path]/scripts/calculate_roi.py --file docs/product/stories.json --users <SOM> --price <PRICE> python3 [skill_path]/scripts/calculate_roi.py --file docs/product/stories.json --users 5000 --price 29.99
Output Interpretation
- NPV (Net Present Value): Must be Positive.
- Payback Period: Ideal < 12 months.
- ROI: Ideal > 3.0x.
- LTV/CAC: Ideal > 3.0x.
- Verdict: Script provides "Strong Case", "Long Game", or "Risky". Trust it.
4. Risk Register
Track top 5 risks using this structure:
| Risk ID | Risk Description | Impact (1-5) | Likelihood (1-5) | Mitigation Strategy |
|---|---|---|---|---|
| R01 | API Limit Hit | 5 | 3 | Use Rotating Proxies |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

skill-product-solution-blueprint is a skill published in the GitHub repository MatrixFounder/Agentic-development (5 stars, last pushed 2d ago), licensed Apache-2.0. It adds 29 tokens to every session and 771 once invoked, about $0.0001 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.

argent-tv-interact
Control and inspect TV apps via argent — Apple TV (tvOS), Android TV (leanback), and Amazon Fire TV (Vega). Boot the target, read focus, navigate with the D-pad remote, type, screenshot, and on Vega debug the JS runtime (evaluate, console logs, network inspector). Use when a task targets a TV (runtimeKind "tv", or…
conversational-ux
Design voice and conversational interfaces — dialog flows, error recovery, and persona. Use when the interface speaks and listens rather than being tapped. For graphical input collection, use form-design.
critique-color
Critique a rendered screen's colour — contrast ratios, palette coherence, and semantic meaning. Use when reviewing one screen. For a product-wide WCAG audit use accessibility-audit (design-systems); for building the palette use color-system (ui-design).
animation-principles
Apply animation principles — easing, staging, follow-through — to one specific UI motion. Use when tuning how an animation feels. For product-wide duration and easing tokens use motion-system (design-systems); for a full interaction spec use micro-interaction-spec.
