Session Summary + Obsidian Documentation

Wrap up the current session by summarizing work, writing Obsidian docs, and syncing memory.

Dynamic Context

Today's date: !date +%Y-%m-%d

Recent commits (this session): !git log --oneline -20

Uncommitted changes: !git diff --stat

Current tasks/todo.md: !cat tasks/todo.md 2>/dev/null || echo "No todo.md found"

Steps

Step 1: Gather session context

Review the full conversation to identify:

• •What was worked on — features added, bugs fixed, refactors done
• •Files changed — use the git context above plus your knowledge of the conversation
• •Decisions made — architectural choices, trade-offs, approach selections
• •Lessons learned — mistakes corrected, patterns discovered, vendor quirks found

Synthesize this into a clear mental model before writing anything.

Step 2: Write session log to Obsidian

Create a date-stamped session note. Derive a short kebab-case slug from the work done (e.g., agent-healthcheck-fix, cjunos-support, vlan-repair-loop).

File: ~/obsidian/Archetype/Sessions/YYYY-MM-DD-<slug>.md

If multiple sessions happened on the same day, append a number: YYYY-MM-DD-<slug>-2.md

Use this format:

# YYYY-MM-DD — <Short Title>

## Summary
<2-3 sentence overview of what was accomplished>

## Changes
- `path/to/file.py` — Description of change
- ...

## Decisions
- <Key architectural or implementation decisions and rationale>

## Lessons Learned
- <Anything notable for future reference>

## Related
- [[Agent]] or [[API]] or [[Networking]] etc. (link to relevant Knowledge docs)

## Tags
#archetype #<area> #<type>

Where <area> is one of: agent, api, frontend, networking, devops, vendors And <type> is one of: bugfix, feature, refactor, investigation, docs

Step 3: Update living Knowledge docs in Obsidian

Directory: ~/obsidian/Archetype/Knowledge/

Topic files (create or update as needed based on what was touched this session):

• •Agent.md — Agent architecture, providers, health checks, networking
• •API.md — Backend API, jobs, state management, auth
• •Frontend.md — React app, canvas, WS state, components
• •Networking.md — OVS, VXLAN, overlay, carrier, VLANs
• •DevOps.md — Deployment, Docker, CI, backups, agent updates
• •Vendors.md — Device-specific configs, quirks, boot detection

Only update topics that were actually touched in this session. Don't update files for areas that weren't worked on.

For each relevant topic file:

• •

  If the file doesn't exist, create it with this structure:

  markdown

  # <Topic>
  
  ## Overview
  <Brief description of this area>
  
  ## Key Files
  - `path/to/key/file.py` — purpose
  
  ## Architecture
  <How this area works>
  
  ## <Section per subtopic>
  > Updated YYYY-MM-DD
  
  <Content>
  
  ## See Also
  - [[Related Topic]]
  

• •

  If the file exists, read it first, then append or update the relevant section:

  • •Add new sections for new topics
  • •Update existing sections with > Updated YYYY-MM-DD marker
  • •Don't duplicate information already present
  • •Use [[wikilinks]] for cross-references

Step 4: Update _Index.md

Update ~/obsidian/Archetype/_Index.md with a table of contents. Read the existing file first if it exists.

Format:

# Archetype Knowledge Base

## Sessions
- [[YYYY-MM-DD-slug]] — Short description
- ...

## Knowledge
- [[Agent]] — Agent architecture and providers
- [[API]] — Backend API and state management
- [[Frontend]] — React app and canvas
- [[Networking]] — OVS, VXLAN, overlay networking
- [[DevOps]] — Deployment and operations
- [[Vendors]] — Device configs and quirks

Only list files that actually exist. Add new session entries at the top of the Sessions list.

Step 5: Update MEMORY.md

Review the current memory file at ~/.claude/projects/-home-azayaka-archetype-iac/memory/MEMORY.md.

• •Add any new stable patterns, key file paths, or architectural decisions discovered this session
• •Update any entries that are now outdated or wrong based on this session's work
• •Remove entries that are no longer accurate
• •Keep it under 200 lines — move detailed content to separate memory files if needed
• •Don't add session-specific or temporary state

Step 6: Update tasks/lessons.md

Read the current tasks/lessons.md file first.

Append any new lessons learned this session using this format:

## YYYY-MM-DD: <Short description>

**Bug/Issue**: <What went wrong or what was discovered>

**Impact**: <Why it matters>

**Fix**: <How it was resolved>

**Rule**: <Prevention rule for the future>

Only add lessons if there are genuine new insights. Don't add trivial or already-documented lessons.

Step 7: Present summary to user

Display a concise summary:

Session complete. Documentation updated:

**Session Log**: ~/obsidian/Archetype/Sessions/YYYY-MM-DD-slug.md
**Knowledge Updated**: <list of topic files touched>
**Memory**: <what was added/changed, or "No changes needed">
**Lessons**: <what was added, or "No new lessons">
