## Configuration

Read `.jobops/config.json`. If missing, stop with:

> JOBOPS NOT CONFIGURED
> Run /jobops:setup to initialize your workspace.

Use `config.directories.<key>` for all file paths in this skill.
Use `config.preferences.cultural_profile` if this skill generates resume-style content.
Use `config.preferences.default_jurisdiction` if this skill has jurisdiction-sensitive logic (crisis/legal skills accept `--jurisdiction=<ISO-3166-2>` to override).

## Usage and Arguments

Creates or updates a GitHub portfolio document.

**Output file:** `{config.directories.career_analysis}/github_portfolio_{YYYYMMDD}.md` — a fresh timestamped snapshot is written on every run (create, add, or refresh).

**Usage forms:**
- `/github-portfolio <repository-url>` — create if no prior snapshot exists, otherwise add the repo to the latest snapshot.
- `/github-portfolio <repository-url> -create` — force a brand-new snapshot (first repository).
- `/github-portfolio <repository-url> -update` — add the repository to the latest existing snapshot.
- `/github-portfolio -update` — full portfolio refresh/reorganization of the latest snapshot (no URL needed).

**Arguments:**
- `$1`: Repository URL (required for adding repositories) OR the `-update` flag for refresh-only mode.
- `$2`: Mode flag (optional, defaults to auto-detect):
  - `-create`: Force create a new portfolio snapshot.
  - `-update`: Force update of the latest portfolio snapshot.

## Step 1: Parse Arguments and Determine Mode

**Repository URL**: $1
**Mode Flag**: ${2:-auto}

Checking arguments:
- If `$1` is `-update` and no `$2`: **Refresh Mode** (reorganize existing portfolio)
- If `$1` is a URL: **Repository Addition Mode** (create or update)
  - If portfolio exists: Update mode
  - If portfolio doesn't exist: Create mode
  - Mode can be forced with `$2` flag

---

## Step 2: Check Portfolio Existence

Checking whether a prior portfolio snapshot already exists in `{config.directories.career_analysis}/` (any file matching `github_portfolio_*.md`). When more than one exists, use the most recent by date suffix as the working snapshot for add/refresh operations.

**Result**: [Snapshot exists/does not exist]

---

## Step 3: Mode Selection

Based on arguments and portfolio existence:
- **Mode**: [CREATE NEW | ADD TO EXISTING | REFRESH EXISTING]

---

## Mode: CREATE NEW PORTFOLIO

**Purpose**: Create initial `github_portfolio_{YYYYMMDD}.md` snapshot with first repository.

**Repository URL Provided**: $1

### Step 3.1: Attempt to Access Repository

I'll try to access the repository directly to read its README and structure.

Attempting to fetch: $1

**Access Methods**:
1. Try WebFetch to read README.md from GitHub URL
2. If that fails (403, private repo, etc.), provide manual analysis script

### Step 3.2A: If Repository Accessible

[If WebFetch succeeds]:
- Read README.md content
- Parse repository name, description
- Attempt to infer technical details from README
- Ask user for additional details (commits, file counts, specific metrics)
- Proceed to create portfolio entry

### Step 3.2B: If Repository NOT Accessible (Most Likely)

[If WebFetch fails with 403/private/inaccessible]:

**The repository is not publicly accessible or I cannot reach it directly.**

No problem! Please run this analysis script in the repository's codespace/terminal and paste the complete results back to me:

```bash
#!/bin/bash
echo "=== REPOSITORY ANALYSIS FOR PORTFOLIO DOCUMENTATION ==="
echo ""
echo "## Basic Repository Information"
echo "Repository: $(basename $(git rev-parse --show-toplevel 2>/dev/null || pwd))"
echo "Current Branch: $(git branch --show-current 2>/dev/null || echo 'N/A')"
echo "Total Commits: $(git rev-list --count HEAD 2>/dev/null || echo 'N/A')"
echo "Last Commit: $(git log -1 --format='%h - %s (%ar)' 2>/dev/null || echo 'N/A')"
echo ""

echo "## File Structure"
echo "Total Files: $(find . -type f -not -path '*/\.*' | wc -l)"

    echo "--- $file ($(wc -l < "$file") lines) ---"
    head -50 "$file"
    echo ""
done

echo "## Git Activity"
echo "Commit History (last 10):"

echo ""

echo "Recent Contributors:"
git shortlog -sn --no-merges | head -5 2>/dev/null || echo "N/A"
echo ""

echo "=== END ANALYSIS ==="
```

**Instructions**:
1. Open a terminal in the repository's codespace or local clone
2. Copy the entire script above
3. Paste it into the terminal and press Enter
4. Copy ALL the output (from "=== REPOSITORY ANALYSIS" to "=== END ANALYSIS ===")
5. Paste the complete output in your next message

Once you provide the analysis, I'll create your initial portfolio entry.

## Mode: ADD TO EXISTING PORTFOLIO

**Purpose**: Add new repository to the latest snapshot and write a new timestamped snapshot.

**Repository URL Provided**: $1

### Step 3.1: Read Latest Portfolio Snapshot

Read the most recent `{config.directories.career_analysis}/github_portfolio_*.md` file.

**Current Portfolio Status**:
- Total repositories: [count from file]
- Next repository number: [N+1]
- Portfolio version: [current version]
- Last updated: [date from file]

### Step 3.2: Attempt to Access Repository

Attempting to fetch: $1

**Access Methods**:
1. Try WebFetch to read README.md from GitHub URL
2. If that fails, provide manual analysis script

### Step 3.3A: If Repository Accessible

[If WebFetch succeeds]:
- Parse repository information
- Ask for additional metrics if needed
- Create comprehensive repository entry
- Update portfolio

### Step 3.3B: If Repository NOT Accessible

**The repository is not publicly accessible.**

Please run this analysis script in the repository's codespace and paste the results:

**After receiving analysis**:
1. Parse repository analysis output
2. Create comprehensive repository entry following established format
3. Insert into Primary Repositories section (next available number)
4. Update capability matrices with new skills/technologies
5. Update conclusion to reference new repository count
6. Increment portfolio version number
7. Update "Last Updated" date

## Mode: REFRESH EXISTING PORTFOLIO

**Purpose**: Full portfolio reorganization and content refresh without adding new repositories.

**Triggered When**: User runs `/github-portfolio -update` with no URL

### Step 3.1: Read Latest Portfolio Snapshot

Read the most recent `{config.directories.career_analysis}/github_portfolio_*.md` file as the working snapshot.

**Current Portfolio Status**:
- Total repositories: [count]
- Portfolio version: [current version]
- Last updated: [date]

### Step 3.2: Comprehensive Review Tasks

1. **Repository Entries Consistency**:
   - Verify all entries follow current template format
   - Check for complete sections in each entry
   - Ensure consistent emoji usage and status indicators
   - Verify all repository links work

2. **Capability Matrices Accuracy**:
   - Review all 11 matrices for current proficiency levels
   - Add any new skills/technologies from recent work
   - Ensure honest positioning (AI-collaborative vs independent)
   - Check evidence references are current

3. **Positioning and Messaging**:
   - Refresh conclusion with current repository count
   - Update "What I Bring" / "What I Don't Claim" sections
   - Review application language examples for relevance
   - Ensure "AI-Collaborative Builder" philosophy is consistent

4. **Table of Contents**:
   - Verify all anchor links work correctly
   - Ensure all repositories are listed
   - Check capability matrix links
   - Confirm career positioning sections are linked

5. **Version and Date**:
   - Increment portfolio version (minor: X.Y+1)
   - Update lastUpdated to today's date in YAML frontmatter
   - Update "Last Updated" at bottom of document

6. **Quality Checks**:
   - Remove any outdated information
   - Fix broken internal references
   - Ensure development philosophy remains honest and accurate
   - Verify all repository counts match

### Step 3.3: Generate Update Summary

After refresh, provide summary of:
- Changes made
- New version number
- Items requiring user attention (if any)

2. **AI-Collaborative Builder**: Domain expert who learned to leverage AI as development partner
3. **What I Bring**: Domain expertise, architectural thinking, AI collaboration skills, proof of capability
4. **What I Don't Claim**: Traditional SWE credentials, ability to code independently, ML engineering qualification
5. **Value Proposition**: Living case study of domain expert to AI builder transformation
