25# Automatic Session Summary
26
27**IMPORTANT**: Please create a session summary and save it to the unified AI storage.
28
29## Instructions
30
31Create a brief summary (2-4 paragraphs) of this session documenting:
32- Primary tasks accomplished
33- Key decisions or solutions
34- Files/systems modified
35- Any remaining work or next steps
36
37Save the summary using the Write tool to:
38\`${dir}/${ds}-<brief-slug>.md\`
39
40**Filename format**: \`YYYY-MM-DD-description-with-dashes.md\`
41- Use only lowercase letters, digits, and dashes
42- Keep description to 3-6 words
43- No underscores, no timestamps beyond the date, no _SESSION_ prefix
44
45**Good examples:**
46- \`${ds}-nix-systems-refactoring.md\`
47- \`${ds}-tekton-pr-review.md\`
48- \`${ds}-pi-extensions-setup.md\`
49
50**Bad examples:**
51- \`${ds}_SESSION_some-thing.md\` (underscore, SESSION prefix)
52- \`${ds}-155616_SESSION_description.md\` (timestamp noise)
53- \`some-thing.md\` (missing date)
54
55Use the **Session Entry** template:
56
57\`\`\`markdown
58# Session: <Description>
59
60**Date:** ${ds}
61**Tool:** claude
