Catch up after absence — summarize git history for a specific user. Use when a user returns after time away from a project and needs to understand what happened — e.g. "warm up", "catch me up", "what happened while I was away", "what did I work on", "summarize recent changes", "what changed since I left", "warm up the project".

CLI Requirement: OPTIONAL — Uses the memory MCP from coding-friend-cli for fast indexed search and storage. Without the CLI: falls back to grep over docs/memory/ and direct file writes. Full functionality preserved, slower memory recall. See CLI requirements.
Catch up after absence. User input: $ARGUMENTS
Purpose
When you return to a project after being away (vacation, sick leave, context switch), you have no idea what happened. This skill summarizes your recent work and everything the team did since your last commit, grouped by topic/area, so you can quickly get back up to speed.
Folder
Output goes to (default: ). Check for custom if it exists.
{docsDir}/warm/
docs/warm/
.coding-friend/config.json
docsDir
IMPORTANT — path resolution:
Use MAIN_REPO_ROOT from the SessionStart bootstrap context (injected via session-init.sh). If absent, fall back to running pwd for $CWD and use $CWD as MAIN_REPO_ROOT.
Read config from CF_CONFIG_FILE (= $MAIN_REPO_ROOT/.coding-friend/config.json) — do NOT search sub-folders
Use CF_DOCS_ROOT as the docs base dir (= $MAIN_REPO_ROOT/{docsDir} where docsDir comes from config, default docs)
Always resolve file_path as an absolute path: {CF_DOCS_ROOT}/warm/{name}.md
Never use relative paths in write specs — they may resolve incorrectly when the working directory contains nested git repos
Workflow
Step 0: Custom Guide
Custom guide — auto-loaded below (if the raw command shows instead of its output, run it yourself):
If output is not empty, integrate returned sections: ## Before → before first step, ## Rules → apply throughout, ## After → after final step.
Step 1: Validate & Configure
Check git repo — run git rev-parse --is-inside-work-tree. If it fails, tell the user: "This directory is not a git repository. /cf-warm only works inside git repos." and STOP.
--user <name> — git author name to look up. If not provided, auto-detect via git config user.name.
--n-commits <N> — number of user's own commits to summarize (default: 10).
If --user is not provided AND git config user.name returns empty, ask the user to provide a name with --user.
Store resolved values as $USER_NAME and $N_COMMITS.
Confirm to the user: "🟢 Warming up as $USER_NAME, looking at your last $N_COMMITS commits."
Step 3: Dry Run — Count Commits
Before fetching full commit data, count how many commits we'll process:
# Get date of user's Nth commit (the cutoff point) — store as $SINCE_DATE
git log --author="$USER_NAME" -n $N_COMMITS --format="%aI" | tail -1
# Count OTHER commits by subtraction (git has no reliable --not-author flag)# Total commits since date:
git log --after="$SINCE_DATE" --oneline | wc -l
# User's commits since date:
git log --after="$SINCE_DATE" --author="$USER_NAME" --oneline | wc -l
# Others = Total - User's
Display the dry run result:
Showing your last $N_COMMITS commits.
Found Y commits by others since $SINCE_DATE.
Safety cap: If Y > 200, warn the user:
⚠️ There are Y commits by others. I'll summarize the most recent 200 to keep the report manageable. Use a more recent --n-commits value to narrow the window.
If the user's name matches zero commits, display a helpful error:
No commits found for author "$USER_NAME". Check git config user.name or use --user "Exact Name" to specify the correct author.
From this output, exclude commits where Author matches $USER_NAME (the LLM filters by comparing the Author field). Apply the 200-commit safety cap on the remaining "other" commits if the dry run showed > 200.
Step 5: Analyze & Cluster
5a. Summarize user's commits:
For each of the user's commits, write a brief 1-2 sentence summary based on the commit message and description. Group related commits together if they're part of the same feature/fix.
5b. Cluster other commits by topic/area:
Read through all other commit messages and group them into logical topics. Use the commit subjects and descriptions to infer the topic — do NOT look at diffs unless a commit message is too vague to classify.
Typical topic groups:
Feature area (e.g., "Authentication", "API", "Frontend", "Database")
Type of work (e.g., "Bug Fixes", "Refactoring", "Infrastructure", "Documentation")
Module/package name (for monorepos)
For each topic group, write:
Topic name (short, descriptive)
Summary (2-3 sentences covering what changed)
Key commits (list the most important 3-5 commits with hash + subject)
Authors involved
Use the language setting from config for the report language.
Step 6: Write Report & Display Summary
6a. Delegate to cf-writer agent:
Construct a write spec and invoke the cf-writer agent by calling invoke_subagent with agent cf-writer.
WRITE SPEC
