[oblt-aw][autodoc] Fix actionable documentation errors in action READMEs

[github-actions]

cc @elastic/observablt-ci

Recent documentation audit found concrete, user-impacting drift in multiple action READMEs.

Changes Requiring Documentation Updates

1. snapshoty/run usage example uses an invalid input key

Evidence:

• snapshoty/run/action.yml:13 defines required input gcs-private-key
• snapshoty/run/README.md:35 uses gcs-private-ley

Documentation impact:
The usage snippet is copy/paste broken and will fail with an unknown input.

2. github/comment-reaction README includes invalid workflow YAML

Evidence:

• github/comment-reaction/README.md:33 has incomplete expression: if: $\{\{ github.event.issue.pull_request
• github/comment-reaction/README.md:34 uses permission: instead of valid permissions:

Documentation impact:
Published usage example is syntactically invalid and not runnable.

3. slack/send README omits a documented action output

Evidence:

• slack/send/action.yml:29-32 defines output thread-timestamp
• slack/send/README.md has Inputs and Usage sections but no Outputs section

Documentation impact:
Consumers cannot discover/document how to reuse thread-timestamp for threaded replies.

4. github/create-token README test badge points to a different action workflow

Evidence:

• github/create-token/README.md:5 links to test-github-user-type.yml
• .github/workflows/test-github-create-token.yml:1 is the correct create-token workflow

Documentation impact:
Cross-reference is misleading and does not represent create-token test status.

Suggested Actions

• In snapshoty/run/README.md, replace gcs-private-ley with gcs-private-key and re-validate usage against action.yml inputs.
• In github/comment-reaction/README.md, fix the if expression and rename permission: to permissions: in the workflow snippet.
• In slack/send/README.md, add an ## Outputs section documenting thread-timestamp and include a usage reference to $\{\{ steps.(id).outputs.thread-timestamp }}.
• In github/create-token/README.md, update the test badge link/text to test-github-create-token.yml.

I’m currently blocked from implementing this because the workflow’s data-integrity policy is preventing me from reading the contents of issue #533 (the issue body/comments are filtered before I can access requirements).

Next step: please provide the issue requirements (or approved summary/acceptance criteria) directly in a comment here, and I can immediately implement the documentation-only changes and open the requested PR with the specified title/body.

Note

🔒 Integrity filtering filtered 1 item

Integrity filtering activated and filtered the following item during workflow execution.
This happens when a tool call accesses a resource that does not meet the required integrity or secrecy level of the workflow.

• issue:[oblt-aw][autodoc] Fix actionable documentation errors in action READMEs #533 (issue_read: has lower integrity than agent requires. The agent cannot read data with integrity below "approved".)
