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.

What it costs to keep this loaded
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 | $0.00120 | $0.00767 |
| Opus 5 | $0.00060 | $0.00383 |
| Sonnet 5 | $0.00024 | $0.00153 |
| Haiku 4.5 | $0.00012 | $0.00077 |
Grade A, and why
032-architecture-adr-non-functional-requirements 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 12d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create ADRs for Non-Functional Requirements
Guide stakeholders through a structured conversation to uncover and document architectural decisions for quality attributes using the ISO/IEC 25010:2023 quality model. This is an interactive SKILL. The ADR documents the outcome of the conversation, not the conversation itself. Act as an architecture consultant: challenge-first, consultative, adaptive. Use only the current conversation and repository files explicitly available in the current session.
What is covered in this Skill?
- Challenge-first opening: ISO 25010:2023 quality characteristics (Functional Suitability, Performance Efficiency, Compatibility, Reliability, Security, Maintainability, Flexibility, Safety)
- Understanding the challenge: drivers, constraints, system context
- Quality-specific deep dive tailored to primary NFR category
- Solution exploration and trade-off preferences
- Decision synthesis and validation before ADR creation
- ADR document generation with Quality Metrics & Success Criteria
Constraints
Use challenge-first, consultative discovery in small batches, build on answers, tailor to NFR category. Only create ADR after thorough conversation and user confirmation.
- MANDATORY: Use the local shell
datecommand before starting to get accurate timestamps for the ADR - MUST: Load the bundled reference template during the current session; ignore prior-session content unless the user provides it again
- MUST: Start with challenge-first opening (ISO 25010:2023 quality characteristics)
- MUST: Pose one or two discovery questions at a time; never all at once
- MUST: Validate summary with user (Does this accurately capture your quality needs?) before proposing ADR creation
- MUST: Wait for user to confirm proceed before generating the ADR
When to use this skill
- Create ADR for Non-functional requirements
- Document Non-functional requirements
- Capture Non-functional requirements
- Generate Non-functional requirements in an ADR
- Create ADR for performance scalability or security requirements
What ships with it
1 file 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.

032-architecture-adr-non-functional-requirements is a skill published in the GitHub repository jabrena/plinth (439 stars, last pushed yesterday), licensed Apache-2.0. It adds 120 tokens to every session and 767 once invoked, about $0.0006 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 2026-08-30.

component-family-consistency
Buttons, inputs, pills, badges, calendars, and other interactive components form a visual family — they share the same border-radius, colour logic, shadow scale, border style, and spacing rhythm. Inconsistency between them breaks the sense of a coherent product. Use when building or reviewing a component library…
modular-scale-typography
Typography feels cohesive and intentional when font sizes follow a modular scale — a ratio-based sequence where every size is mathematically related to the others. Use when defining type scales, setting up design tokens, reviewing font size choices, or when typography feels inconsistent or arbitrary.

Extract a complete design system — colors, typography, spacing, components, shadows, and W3C design tokens — from any live website using Dembrandt. Runs a headless browser against the URL and returns real computed values from the DOM. Use when you need a site's actual design tokens, want to reverse-engineer a visual…

A brand's visual tone — playful or serious, rounded or angular — should be consistent across all UI elements.

Complex data deserves multiple view modes — grid, list, table — chosen by the user based on their task. Row and item selection should use large hit areas (the whole row or card, not just a checkbox). Selected state is communicated through a subtle background colour shift. Mass actions appear when items are selected.…
