Description

Implements automated spelling checks in CI using codespell to catch typos before merge.

Workflow (.github/workflows/codespell.yml):

• Runs on pushes to main and all PRs
• Uses codespell-project/actions-codespell@v2
• Checks file contents and filenames

Configuration (.codespellrc):

• Ignores intentional example typos (e.g., Line Numer in add-educational-comments.prompt.md)
• Whitelists technical terms: AKS, EDN, rouge, categor (TS template literal), ative (Declarative), afterall, deques
• Skips generated artifacts: node_modules, package-lock.json, website builds

Spelling Fixes:

• Fixed spelling error in .github/copilot-instructions.md: "formated" → "formatted"

Verified locally: catches real errors (seperate → separate, formated → formatted), ignores whitelisted terms, zero false positives on current codebase.

---

Type of Contribution

• New instruction file.
• New prompt file.
• New agent file.
• New collection file.
• New skill file.
• Update to existing instruction, prompt, agent, collection or skill.
• Other (please specify): CI workflow addition and spelling fix

---

Additional Notes

Addresses request to add regular spelling checks to CI. Spelling errors from PR #639 were already fixed; this adds automation to prevent future issues. The CI workflow successfully detected and we fixed a spelling error in .github/copilot-instructions.md that was introduced in the repository.

This section details on the original issue you should resolve

<issue_title>Spelling and grammar auto-check</issue_title>
<issue_description>Below is a list of spelling issues that were detected by running codespell on this repo:

File	Line	Text	Issue	Suggested correction
instructions/oqtane.instructions.md	34	"Each action in the client module is a seperate razor file that inherits from ModuleBase with index.razor being the default action."	Misspelling of "separate"	Replace "seperate" with "separate"
instructions/oqtane.instructions.md	66	"Avoid adding extra depenencies like Fluxor or BlazorState when the application grows in complexity."	Misspelling of "dependencies"	Replace "depenencies" with "dependencies"
instructions/tasksync.instructions.md	22	"Use chat for Informations."	Incorrect pluralization	Replace "Informations" with "information"
instructions/dotnet-upgrade.instructions.md	41	"Post Builds are successfull only after success completion update the CI/CD files"	Misspelling of "successful"	Replace "successfull" with "successful"
agents/rust-gpt-4.1-beast-mode.agent.md	92	"...continue on to the next step after checkin off a step..."	Misspelling of "checking"	Replace "checkin" with "checking"
prompts/cosmosdb-datamodeling.prompt.md	44	"...top Entities colections and Documents retention if any for main Entities, total requests/second across all major accelss patterns"	Misspellings of "collections" and "access"	Replace "colections" with "collections" and "accelss" with "access"
prompts/cosmosdb-datamodeling.prompt.md	618	"...would require siginificant Cosmos DB partition/size..."	Misspelling of "significant"	Replace "siginificant" with "significant"
prompts/update-avm-modules-in-bicep.prompt.md	8	"...final outout table and summary."	Misspelling of "output"	Replace "outout" with "output"
skills/refactor/SKILL.md	299	"# EVEN BETER: Using Result type"	Misspelling of "better"	Replace "BETER" with "BETTER"
prompts/add-educational-comments.prompt.md	64	"...Interpret obvious typos (e.g., Line Numer) using context."	Misspelling in example input	Replace "Line Numer" with "Line Number" (appears at lines 64, 118, 121)

I can send a PR to fix these -- except for the last one, in which Line Numer should not be corrected because it is an example of an intentional misspelling.

Longer-term, should there be a regular or automatic process to check all files for spelling and grammar?</issue_description>

<agent_instructions>These errors were mostly addressed in #639 but can you now add an action using https://github.com/codespell-project/actions-codespell that will run on CI to fix spelling errors</agent_instructions>

Comments on the Issue (you are @copilot in this section)

@aaronpowell Yes, do send through a PR to correct them, and it'd be good if you could include a GitHub Actions workflow that could be part of the CI process to catch this stuff (I won't pretend I could catch it as I'm appalling at spelling myself 🤣).

• Fixes Spelling and grammar auto-check #636
