Summary

Fixes a collection of inaccuracies, broken syntax, and language issues across action.yml, README.md, and CONTRIBUTING.md. No behavior or logic changes — documentation only.

Changes

action.yml

• Action name: added "and Pull Requests" — the action processes both, and the omission was inconsistent with the README title
• repo-token description: fixed broken template expression ({{ → ${{)
• ignore-updates / ignore-issue-updates / ignore-pr-updates: descriptions were inverted — they described what happens when the option is false (the default), not what enabling it does; rewrote to accurately state that setting to true switches staleness calculation from updated_at to created_at
• close-issue-reason: documented the two valid values (completed, not_planned) and that an invalid value causes the action to fail (enforced in main.ts)
• days-before-close / days-before-issue-close / days-before-pr-close / operations-per-run: added "Must be an integer" — all four use parseInt with explicit NaN validation that calls core.setFailed
• days-before-stale: added note that fractional values are accepted (uses parseFloat)
• only-issue-labels / only-pr-labels / only-issue-types: corrected default from [] to '' — the actual default is an empty string
• sort-by: documented that unrecognised values silently fall back to created rather than erroring
• start-date: documented that an invalid date format fails the action
• exempt-draft-pr: corrected stale note — since June 2022 the draft flag is read from the issue list payload; no additional API call is made
• exempt-all-milestones / exempt-all-assignees: normalised "Default to false" → "Defaults to false"
• Outputs: corrected type from "List" to "JSON array" (values are JSON.stringify-encoded); reordered to match declaration order in main.ts
• Grammar: "closing a pull requests" → "closing a pull request"

README.md

• Fixed Node.js version references: node20 / node 24 → Node.js 20 / Node.js 24 (canonical branding)
• Fixed hyphenation: comma separated → comma-separated in five option descriptions (compound modifier rule)
• Fixed subject-verb agreement: consume → consumes, display → displays
• Fixed conditional tense: If you reached the limit → If you reach the limit

CONTRIBUTING.md

• Fixed canonical branding: typescript → TypeScript
• Fixed grammar: a bump of version will happen → the version will be bumped
• Fixed punctuation: added missing comma in Otherwise, PR checks will fail.

Impact

• Users: more accurate action.yml descriptions surface in the GitHub Actions UI and autocomplete, reducing misconfiguration
• ignore-updates fix: the corrected description may change how users understand and set this option — previously the description implied the opposite of what true does
• Backward compatibility: no inputs, outputs, or defaults were changed; all modifications are description/documentation only

Testing

These are documentation-only changes with no executable code modifications.
Verified by cross-referencing each description against the corresponding core.getInput call in src/main.ts, the IIssuesProcessorOptions interface, and the processing logic in src/classes/issues-processor.ts.
