Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

SkillSpector: 14 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00046 | $0.07829 |
| Opus 5.5 | $0.00018 | $0.03132 |
| Sonnet 5.5 | $0.00009 | $0.01566 |
| Haiku 4.5 | $0.00005 | $0.00783 |
Grade A, and why
documentation-standards scanned grade A with 1 finding 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 20d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Documentation Standards
Overview
Comprehensive documentation standards based on research from Google, Microsoft, GitLab, Red Hat style guides, and 60+ additional sources. Provides templates, best practices, and anti-pattern detection for AI agents writing documentation.
15 Best Practices (Ranked by Consensus)
UNANIMOUS (100% Agreement)
1. Use Active Voice and Present Tense
Why: Reduces cognitive load 20-30%, shortens sentences 15-25%
Implementation:
BAD (passive): The request is processed by the server.
GOOD (active): The server processes the request.
BAD (future): The program will save your file.
GOOD (present): The program saves your file.
Validation: Check for "is/are/was/were + past participle" patterns
2. Start with 5-Minute Quick Start
Why: 70% of visitors are first-time users, time-to-first-success critical
Implementation:
## Quick Start
```bash
npm install my-tool
npx my-tool init
npx my-tool start
Visit http://localhost:3000
That's it!
**Validation**: Can a new user succeed in under 5 minutes with zero context?
---
#### 3. Use Progressive Disclosure (Three-Tier Structure)
**Why**: Accommodates all skill levels, reduces overwhelm
**Implementation**:
Tier 1: Quick Start (2-5 min) -> Copy-paste code, immediate success, no explanations
Tier 2: Tutorial (15-30 min) -> Step-by-step with explanations, build one feature
Tier 3: Reference (lookup) -> Complete API docs, searchable, advanced patterns
---
#### 4. Use Second Person ("You")
**Why**: Increases engagement, reduces word count 15-25%
**Implementation**:
```markdown
BAD: The user should configure the settings.
GOOD: Configure the settings.
BAD: One can install the plugin by...
GOOD: Install the plugin by...
5. Keep Sentences Short (Rule S2)
Why: Long sentences cost comprehension. Rule S2 sets the numbers: average 15-20 words, at most one 26-40 word sentence per paragraph, none over 40.
What ships with it
2 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.

- 1mo ago First seen · 1,184 lines · 46 tokens per session scan A 9c6b88a02f33
documentation-standards is a skill published in the GitHub repository MadAppGang/magus (13 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 7,829 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
