fix: resolve all vale linting errors (#298)
* feat: implement production-grade vale linting configuration ## Summary This commit establishes a comprehensive, maintainable Vale configuration for auth4genai documentation that catches real errors while minimizing false positives in code-heavy and example-driven content. ## Key Changes - **Fixed all 73 Vale linting errors** across 41 files (brand capitalization, spelling, HTML structure) - **Created custom AuthDocs style bundle** with Brands.yml (systematic corrections like github→GitHub) and Spelling.yml (domain-specific ignore list) - **Configured path-based rule overrides** for snippets, components, sample apps, and GitHub integration pages where strict rules generate noise - **Aligned MinAlertLevel = error strategy** with explicit rule disabling instead of severity demotion (clear, maintainable, no false expectations) - **Documented configuration thoroughly** with concrete MDX examples, workflow guidance, and clear explanation of tradeoffs ## Technical Details - StylesPath correctly maps to .vale/styles where all rules and ignore lists live - BasedOnStyles = Vale, AuthDocs applied consistently to MD and MDX files - Vale.Spelling disabled globally; replaced with AuthDocs.Spelling for domain-aware checking - AuthDocs.Brands disabled only on paths where word boundary matching triggers on URLs/domains (documented pattern and escape hatch in README) - IgnoredScopes/SkippedScopes intentionally exclude link text and code blocks to focus on prose ## Vale Status ✓ 0 errors, 0 warnings, 0 suggestions across 137 files ## Maintenance Future updates are purely content-driven: - Add terms to .vale/styles/config/ignore/authdocs.txt as new jargon emerges - Add substitutions to .vale/styles/AuthDocs/Brands.yml for systematic fixes - Adjust path-based disables in .vale.ini for new files with false positives

# Vale Linting
2+
3+
This directory contains the Vale configuration used to lint and standardize the documentation in `auth4genai`. Vale helps ensure consistent terminology, brand usage, spelling, and overall prose quality.
4+
5+
## Requirements
6+
7+
To run Vale with MDX support, you must have:
8+
9+
- **Vale 3.13.0 or newer**
10+
- **mdx2vast 0.3.0 or newer**
11+
- Node.js and npm installed
12+
- Both `vale` and `mdx2vast` available on your `$PATH`
13+
14+
## Installation
15+
16+
Vale must be installed locally before running checks. MDX support additionally requires the external parser `mdx2vast`.
17+
18+
Install Vale ([docs](https://vale.sh/docs/install)):
19+
20+
```bash
21+
brew install vale
22+
```
23+
24+
Install the MDX parser ([MDX format docs](https://vale.sh/docs/formats/mdx)):
25+
26+
```bash
27+
npm install -g mdx2vast
28+
```
29+
30+
Both executables must be available in your `$PATH`.
31+
32+
Run Vale from the `auth4genai` directory:
33+
34+
```bash
35+
vale .
36+
```
37+
38+
A clean run should report zero errors. If you see unexpected output, refer to the [MDX behavior notes](https://vale.sh/docs/formats/mdx#behaviors) for details on what Vale ignores by default.
39+
40+
## How MDX content is interpreted
41+
42+
> **Important:** MDX files do *not* support HTML comments (`<!-- vale off -->`).
43+
> Always use MDX comment syntax instead:
44+
>
45+
> ```mdx
46+
> {/* vale off */}
47+
> ...ignored content...
48+
> {/* vale on */}
49+
> ```
50+
51+
Vale parses `.mdx` files using `mdx2vast`. The parser automatically ignores:
52+
53+
* `import` and `export` statements
54+
* JSX components and JSX blocks
55+
* fenced code blocks
56+
* inline backtick code
57+
* URLs (see [URL handling](https://vale.sh/docs/topics/urls))
58+
* single-line `{ ... }` JavaScript expressions
59+
60+
These defaults help avoid false positives in pages that combine prose with examples, components, and structured metadata.
61+
62+
Inline MDX-aware controls are supported when necessary. MDX files use curly-brace comment syntax (not HTML comments):
63+
64+
```mdx
65+
{/* vale off */} …ignored… {/* vale on */}
66+
{/* vale Style.RuleName = NO */}
67+
{/* vale Style.RuleName["match"] = NO */}
68+
```
69+
70+
For example, to disable the custom spelling rule for a specific word that would normally be flagged:
71+
72+
```mdx
73+
{/* vale AuthDocs.Spelling["ocurrance"] = NO */}
74+
This misspelling is intentional in this context and should be skipped.
75+
{/* vale AuthDocs.Spelling["ocurrance"] = YES */}
76+
```
77+
78+
**Note:** These are MDX-style comments. HTML comments (`<!-- vale off -->`) will not work in `.mdx` files.
79+
80+
Guidance on these controls:
81+
[https://vale.sh/docs/topics/config/#comment-based-controls](https://vale.sh/docs/topics/config/#comment-based-controls)
82+
83+
## Configuration structure
84+
85+
All configuration begins with a single file: `.vale.ini`. That file loads a custom style bundle located under `.vale/styles`.
86+
87+
### `.vale.ini`
88+
89+
* Configures MDX and Markdown behavior using a shared style stack
90+
* Enables project-specific rules via `AuthDocs`
91+
* Sets global defaults such as `MinAlertLevel = error` (only error-level issues are reported; suggestions and warnings are suppressed)
92+
* Applies overrides for snippet directories, component demos, and sample-app index pages
93+
* Contains path-based exceptions for content where strict linting generates false positives
94+
95+
See the Vale config reference:
96+
[https://vale.sh/docs/topics/config](https://vale.sh/docs/topics/config)
97+
98+
### `.vale/styles/AuthDocs/Spelling.yml`
99+
100+
Defines a custom spelling rule that replaces Vale’s default spellchecker.
101+
This rule:
102+
103+
* Uses project-specific ignore lists
104+
* Reduces noise from acronyms, product names, config keys, or identifiers
105+
* Helps catch real typos while avoiding false positives
106+
107+
Vale spelling check reference:
108+
[https://vale.sh/docs/checks/spelling](https://vale.sh/docs/checks/spelling)
109+
110+
The ignore list it relies on lives at:
111+
112+
```
113+
.vale/styles/config/ignore/authdocs.txt
114+
```
115+
116+
### `.vale/styles/config/ignore/authdocs.txt`
117+
118+
Contains domain-specific vocabulary:
119+
120+
* Product names
121+
* Framework and platform names
122+
* Identifiers and config keys
123+
* Project jargon
124+
* Terms we expect to appear in code or prose without being flagged
125+
126+
See the “ignore files” section of the spelling check docs:
127+
[https://vale.sh/docs/checks/spelling/#ignore-files](https://vale.sh/docs/checks/spelling/#ignore-files)
128+
129+
This file should be kept up to date as terminology evolves. Mintlify’s maintenance guidance is helpful here:
130+
[https://www.mintlify.com/guides/maintenance](https://www.mintlify.com/guides/maintenance)
131+
132+
### `.vale/styles/AuthDocs/Brands.yml`
133+
134+
Contains substitution rules for:
135+
136+
* brand capitalization (for example, `github` → `GitHub`, `javascript` → `JavaScript`)
137+
* recurring misspellings
138+
* invalid plurals (for example, `SDK's` → `SDKs`)
139+
140+
Vale substitution check reference:
141+
[https://vale.sh/docs/checks/substitution](https://vale.sh/docs/checks/substitution)
142+
143+
Only systematic, project-wide corrections should be added.
144+
145+
**Note:** If a file generates repeated false positives from brand checks (for example, GitHub URLs on an integration page), the preferred approach is to disable `AuthDocs.Brands` for that path in `.vale.ini` rather than adding exceptions to the rule. See the "MDX and Markdown overrides in `.vale.ini`" section below.
146+
147+
### MDX and Markdown overrides in `.vale.ini`
148+
149+
Certain paths contain examples, generated text, or content where strict rules generate noise. In these paths we disable or relax specific rules:
150+
151+
* `snippets/**/*.mdx` – brand checks disabled
152+
* `components.mdx` – brand and spelling checks disabled
153+
* `sample-apps.mdx` and `mcp/sample-apps.mdx` – brand checks disabled
154+
* overview or card-heavy pages (`how-tos/overview.mdx`) – brand checks disabled
155+
156+
These overrides help keep CI output stable without disabling important linting elsewhere.
