docs(task): summarize tiny.txt attachment

[krokoko]

Summary

• Read the attached file tiny.txt located at .attachments/01KSESSQAWBRQBXCXKP2WSSRK8/tiny.txt.
• The file contains a single word: "hello".
• One-sentence summary: The file tiny.txt contains a single word: "hello."

Changes

A task-notes file was added to document the result. No plugin or source code was modified.

Build and test results

No build or lint run was required since no source files were modified. The branch adds only a documentation note under .task-notes/.

Decisions made

The task requested a one-sentence summary of the attachment. Since the file's entire content is the word "hello", the summary is trivially derived. A minimal .task-notes/ file was committed to enable PR creation (the branch needs at least one commit).

Agent notes

• What went well: Simple read-only summarization task with no ambiguity.
• What was difficult: Nothing — the file was tiny (one word).
• Patterns discovered: Attachments are stored under .attachments/<task-id>/ in the workspace root; that directory is not tracked by git.
• Suggestions: For pure summarization tasks with no code changes, consider allowing the workflow to document results without requiring a PR commit — or pre-seed the branch with a placeholder commit.
