What does this implement/fix?

Adds automated checks to every pull request into dev and main, so the problems found in the two cleanup rounds can't come back. Problems show up as annotations on the PR's changed lines.

Check Fails the PR on
check_markdown.py Missing front matter title or description, heading levels that skip, more than one H1, images without alt text, snippet includes that are missing or start inside the included page's front matter
check_secrets.py ESPHome API encryption keys, generated OTA passwords, passwords typed into YAML, access tokens (allows !secret and placeholders)
check_images.py Photos with GPS location data
check_links.py Broken links, missing #anchors, filename case mismatches, and images without alt text on the built site, including site-style links MkDocs doesn't validate

Warnings only (don't fail): em dashes and banned filler words; images or recordings over 1.5 MB that the PR adds or changes.

Tested: all four pass on the current wiki. In a scratch copy with one planted example of every problem (heading skip, missing alt, second H1, include into front matter, real-looking API key, OTA password, typed Wi-Fi password, GPS-tagged photo, broken link, missing anchor), every one was caught. This PR's own run is the end-to-end test on GitHub.

Also adds front matter titles to the 29 pages that lacked one (all outside the menu), so the title rule passes from day one. CONTRIBUTING.md, AGENTS.md, STYLE_GUIDE.md, and the new tools/docs-checks/README.md explain the checks, how to fix each failure, and how to run them locally.

Optional follow-up for a repo admin: to make the checks block merging, add checks (from the docs-checks workflow) as a required status check in the branch protection for dev and main.

Types of changes

  • Typo / wording fix
  • Content update (correcting outdated info, adding missing steps, clarifications)
  • New page or new product section
  • Page move / rename (redirect added in mkdocs.yml)
  • Image / screenshot update
  • Nav / structure change
  • Site config or theme change
  • CI / workflows / dependencies — Does not publish

Checklist:

  • This PR targets the dev branch (not main)
  • Changes previewed locally with mkdocs serve (verified with mkdocs build and the new checks instead)
  • If pages were moved or renamed, redirects were added to mkdocs.yml
  • If new pages were added, nav was updated in mkdocs.yml

Summary by CodeRabbit

  • New Features
    • Pull requests now receive automated documentation checks for formatting, page metadata, links and anchors, image descriptions, and exposed credentials.
    • Image checks flag GPS metadata and warn about oversized media files.
  • Documentation
    • Updated contributor guidance explains what the checks cover, how to run them locally, and what to review manually in screenshots and recordings.
    • Added or clarified titles across documentation pages to improve page identification.

Every page now has a title: in its front matter, so the new PR check
can require it. Wrapper pages take the title of the page they include;
the rest use their H1. All 29 are pages that aren't in the menu
(mostly old Homey copies and the LED-1 and H-3 trees).

A new docs-checks workflow runs on PRs into dev and main and reports
problems as annotations on the changed lines:

- check_markdown.py: front matter title and description, heading
  levels that skip, more than one H1, images without alt text, and
  snippet includes that are missing or start inside the included
  page's front matter. Warns on em dashes and banned filler words.
- check_secrets.py: ESPHome API encryption keys, generated OTA
  passwords, passwords typed into YAML, and common token formats
  (allows !secret and obvious placeholders).
- check_images.py: photos carrying GPS location data. Warns on images
  over 1.5 MB that the PR adds or changes.
- check_links.py: links, #anchors, filename case, and alt text on the
  built site, including the site-style links MkDocs doesn't validate.

All four pass on the current wiki, and each was shown to fail on a
planted example of every problem it covers. CONTRIBUTING.md, AGENTS.md,
STYLE_GUIDE.md, and tools/docs-checks/README.md explain the checks and
how to fix or run them; the style guide now also covers trimming
secrets from recordings and stripping photo location data.

Walkthrough

This change adds automated documentation checks for Markdown, credentials, image metadata, and built-site links. A GitHub Actions workflow runs the checks on pull requests and manual dispatch. Documentation titles and contributor guidance are also updated.

Changes

Documentation validation

Layer / File(s) Summary
Markdown checks and page metadata
tools/docs-checks/check_markdown.py, tools/docs-checks/README.md, docs/homey/products/air1/..., docs/homey/products/general/..., docs/homey/products/led1/..., docs/homey/products/mtr1/..., docs/homey/products/rpro1/..., docs/products/apolloodroid/..., docs/products/general/..., docs/products/h3/...
The Markdown checker validates front matter, headings, image alt text, and snippet includes. It reports configured wording issues as warnings. The listed pages gain front-matter titles.
Secret and image checks
tools/docs-checks/check_secrets.py, tools/docs-checks/check_images.py, tools/docs-checks/README.md, STYLE_GUIDE.md
The checks scan documentation for credential patterns and image assets for GPS metadata. Large media files generate warnings. The style guidance covers sensitive information in screenshots and recordings and GPS metadata in photos.
Built-site link checks
tools/docs-checks/check_links.py, tools/docs-checks/README.md
The checker validates local and supported wiki links, anchors, URL case, and image alt text in built pages. The README documents local setup and commands.
Workflow and contributor guidance
.github/workflows/docs-checks.yml, AGENTS.md, CONTRIBUTING.md
The workflow runs on pull requests targeting dev or main and on manual dispatch. It runs the checks, builds the site, and checks the built output. Contributor guidance describes the checks and manual inspection of media.

Merge Risk: 🟡 Moderate · up to d5d17

The new documentation checks are useful but leave real gaps in two safeguards. The secret check misses plain-text YAML passwords and skips any line that also contains a !secret reference. The photo location check can pass without checking a file if ExifTool hits an error. Close these gaps before relying on the checks as a merge gate. The other findings are smaller fixes to check accuracy and contributor guidance.

to call findings “check annotations” rather than “comments,” and direct
contributors to the GitHub Actions Checks tab to find them.

Review comments at @STYLE_GUIDE.md:
- Around line 424-427: Replace the `-gps:all=` removal command with the quoted
`-gps*=` wildcard command in the photo-location guidance and both remediation
hints emitted by the image checker, including its GPS error message.

Review comments at @tools/docs-checks/check_images.py:
- Around line 35-36: Update the CHANGED_FILES parsing in the changed-path setup
to split on line boundaries rather than whitespace, preserving spaces within
filenames; keep the existing path normalization and behavior when the variable

- Around line 26-30: Update the ExifTool subprocess handling around `r` so exit
status 1 fails the check and reports `stderr`, while preserving status 2 as
valid when no files match the GPS condition.

Review comments at @tools/docs-checks/check_links.py:
- Around line 108-114: Update src_md to recognize the root URL /index.html and
resolve it to the existing root source page, including index.md or README.md as
applicable. Build returned annotation paths from DOCS rather than the hard-coded
"docs/" prefix, normalizing separators for GitHub paths.
- Around line 102-104: Update exists() to distinguish an exact match from a
case-insensitive match, then report a case mismatch once as an error attached to
the source page and skip the generic broken-link path. Ensure the reported total
counts that link only once.

Review comments at @tools/docs-checks/check_markdown.py:
- Line 58: Update the front-matter value checks in the Markdown checker to match
horizontal whitespace after `title:` and `description:` so a following field
cannot satisfy a blank value. Keep each value check confined to its own line.
- Line 90: Update the image alt-attribute check in the Markdown validation flow
to recognize case-insensitive `alt` attributes with either single or double
quotes, while still requiring a nonempty value; use an HTML parser if
appropriate instead of the current double-quote-only search.

Review comments at @tools/docs-checks/check_secrets.py:
- Around line 44-45: Update the secret-suppression condition to check for
`!secret` in the matched value rather than anywhere in `line`, while preserving
the `PLACEHOLDER.search(value)` exemption. Ensure a separate `!secret` reference
or comment does not suppress detection of a real key on the same line.
- Line 26: Update the “password typed in YAML” pattern in the secrets check to
capture scalar values whether quoted or unquoted, excluding surrounding quotes
from the capture. Ensure the existing placeholder exclusions are applied to the
captured value in either form.

Review comments at @tools/docs-checks/README.md:
- Around line 33-34: Move the exiftool prerequisite in the local-check section
above the command block and format it as a GitHub-native note alert. Preserve
the existing installation guidance and remove its current placement after the
commands.

ExifTool official documentation unqualified GPSLatitude XMP GPS tags -gps*= delete wildcard

💡 Result:

`-GPS*= ` (without the space) is a **tag-name wildcard**, not a request to delete only the EXIF GPS group. ExifTool’s official docs say unqualified tag names are updated in the preferred group **and any other location where a same-named tag already exists**; its API docs explicitly distinguish `gps*` from `gps:*`, noting that `gps*` also matches XMP GPS tags. So, for example, `-GPSLatitude=` can remove same-named EXIF and XMP tags if both are present, while `-GPS*=` deletes tags whose names start with “GPS” across groups. ([exiftool.org](https://exiftool.org/exiftool_pod2.html?utm_source=openai))

To target a group, qualify it: `-EXIF:GPS*=` for EXIF or `-XMP:GPS*=` for XMP. The official docs specifically show `-gps:all=` to delete the GPS group, and `-xmp:geotag=` to delete XMP GPS tags written by the geotag feature. Quote wildcard arguments on shells that expand `*`, e.g. `'-GPS*='`. ([exiftool.org](https://exiftool.org/exiftool_pod2.html?utm_source=openai))

The docs list XMP GPS tags such as `GPSLatitude` and `GPSLongitude`; the EXIF GPS table separately documents EXIF GPS tags. Thus the shared, unqualified names can refer to tags in either metadata group. ([exiftool.org](https://exiftool.org/TagNames/XMP.html?utm_source=openai))

- 3: https://exiftool.org/TagNames/XMP.html?utm_source=openai

Use the wildcard GPS removal command.

-gps:all= can leave XMP GPS coordinates. The checker’s unqualified GPSLatitude and GPSLongitude conditions can still detect those coordinates, so the contributor can remain blocked by a failing check. The checker does not publish the photo undetected, so this is a minor functional issue rather than a major security or privacy issue.

Update the command in STYLE_GUIDE.md and both hints in tools/docs-checks/check_images.py:

Fail when ExifTool cannot complete the GPS check.

If ExifTool reports a file-read or processing error and produces no matching output, this script exits successfully. GPS data in that file remains unverified. Handle exit status 1 as a check failure and report stderr. Preserve status 2 as the valid case in which every file fails the GPS -if condition. (exiftool.org)

Split changed paths by line, not by whitespace.

The workflow supplies newline-separated paths. For a changed file such as docs/assets/setup photo.jpg, split() creates two entries, so the size warning never appears. Use splitlines() to preserve spaces in filenames.

Keep the front-matter value check on one line.

If title: is blank and description: follows it, \s* consumes the newline and \S matches the next field. The checker then accepts a page without a title. The same pattern can accept a blank description: when another field follows it. Match horizontal whitespace only, or parse the front matter as YAML.

Review comment at @tools/docs-checks/check_markdown.py at line 58:
Update the front-matter value checks in the Markdown checker to match horizontal
whitespace after `title:` and `description:` so a following field cannot satisfy
a blank value. Keep each value check confined to its own line.

Recognize valid HTML alt attributes.

If an image uses <img src="sensor.png" alt='Sensor'> or an uppercase ALT attribute, this search reports a missing alt value. Both attributes provide alt text, so the Markdown step can fail on valid markup. Accept valid attribute quoting and case, preferably with an HTML parser.

Review comment at @tools/docs-checks/check_markdown.py at line 90:
Update the image alt-attribute check in the Markdown validation flow to
recognize case-insensitive `alt` attributes with either single or double quotes,
while still requiring a nonempty value; use an HTML parser if appropriate
instead of the current double-quote-only search.

Scan unquoted YAML passwords.

If a page contains password: actualvalue123, this pattern does not match it. YAML accepts that value without quotes, so the advertised password check passes a published password. Match quoted and unquoted scalar values, then apply the placeholder exclusions to the captured value.

Update the “password typed in YAML” pattern in the secrets check to capture
scalar values whether quoted or unquoted, excluding surrounding quotes from the
capture. Ensure the existing placeholder exclusions are applied to the captured
value in either form.

Limit !secret suppression to the matched value.

If a line contains a real key and a separate !secret reference or comment, if "!secret" in line suppresses the real key. Check whether the matched value itself is a !secret reference. Do not exempt other credentials on the line.

Update the secret-suppression condition to check for `!secret` in the matched
value rather than anywhere in `line`, while preserving the
`PLACEHOLDER.search(value)` exemption. Ensure a separate `!secret` reference or
comment does not suppress detection of a real key on the same line.

Move the exiftool prerequisite above the local-check commands.

This README is rendered on GitHub, not by MkDocs, so !!! note would appear as plain text. Use a GitHub-native note alert while preserving the prerequisite guidance.
