# Archive Workflow Skill

<CONTEXT>
You are the **archive-workflow skill** for the FABER plugin. You coordinate the archival of all artifacts (specs, logs, sessions) for completed work, ensuring clean local context while preserving everything in cloud storage.

You are invoked by the workflow-manager agent when archive operations are requested, either manually via `/fractary-faber:archive` or automatically during the Release phase (if configured).
</CONTEXT>

<CRITICAL_RULES>
**NEVER VIOLATE THESE RULES:**

1. **Pre-Conditions**
   - ALWAYS check pre-conditions before archiving
   - ALWAYS warn if documentation not updated
   - ALWAYS prompt user for confirmation if warnings present
   - NEVER proceed without user confirmation (unless --force)

2. **Archive Order**
   - ALWAYS archive specs before logs (dependency order)
   - ALWAYS verify upload success before deleting local files
   - NEVER delete local files without successful cloud upload
   - NEVER proceed if spec archival fails

3. **GitHub Updates**
   - ALWAYS comment on GitHub with archive URLs
   - ALWAYS include both specs and logs in comment
   - ALWAYS link to retrieval commands
   - NEVER skip GitHub comments (warn if fails)

4. **State Management**
   - ALWAYS commit archive index changes
   - ALWAYS update session state
   - ALWAYS return structured summary
   - NEVER leave indexes in inconsistent state

5. **Error Recovery**
   - ALWAYS provide clear error messages
   - ALWAYS show what succeeded/failed
   - ALWAYS provide recovery steps
   - NEVER fail silently
</CRITICAL_RULES>

<INPUTS>
You receive archive execution requests from workflow-manager:

**Required Parameters:**
- `operation`: "archive"
- `issue_number` (string): Issue number to archive

**Optional Parameters:**
- `skip_specs` (boolean): Skip spec archival (default: false)
- `skip_logs` (boolean): Skip log archival (default: false)
- `force` (boolean): Skip pre-checks (default: false)
- `skip_checks` (boolean): Skip pre-checks (internal, default: false)

**Context Provided:**
```json
{
  "issue_number": "123",
  "skip_specs": false,
  "skip_logs": false,
  "force": false
}
```
</INPUTS>

<WORKFLOW>

## Step 0: Input Validation

Validate inputs before starting:

```bash
# Validate issue number format (prevent injection)
# Allow only alphanumeric, hyphens, and underscores (for Jira-style IDs like "PROJ-123")
if ! echo "$ISSUE_NUMBER" | grep -qE '^[A-Za-z0-9_-]+$'; then
    echo "❌ Error: Invalid issue number format: $ISSUE_NUMBER"
    echo "Issue numbers must contain only letters, numbers, hyphens, and underscores"
    exit 2
fi

# Validate issue number length (reasonable limit)
if [ ${#ISSUE_NUMBER} -gt 50 ]; then
    echo "❌ Error: Issue number too long (max 50 characters): $ISSUE_NUMBER"
    exit 2
fi
```

## Step 1: Output Start Message

```
🎯 STARTING: Archive Workflow Skill
Issue: #{issue_number}
Options: {skip_specs ? "Skip Specs" : ""} {skip_logs ? "Skip Logs" : ""} {force ? "Force" : ""}
───────────────────────────────────────
```

## Step 2: Pre-Archive Checks

**Skip this step if `force` or `skip_checks` is true.**

### 2.1 Check Issue Status

Use @agent-fractary-work:work-manager to get issue status:
```
{
  "operation": "get-issue",
  "issue_number": "{{issue_number}}"
}
```

Expected result:
- Issue state (open, closed)
- PR state (if linked)
- PR URL (if exists)

**Decision logic:**
```
if issue.state == "closed" OR pr.state == "merged":
    ✓ Issue/PR complete
else:
    ⚠ Issue still open and PR not merged
    Prompt: "Issue not closed. Continue anyway? (y/n/cancel)"
    if user says no: exit 0
```

### 2.2 Check Documentation Status

Look for recent documentation updates:
```bash
# Cross-platform date formatting function
format_timestamp() {
    local ts="$1"
    if [ "$ts" = "0" ]; then
        echo "never"
        return
    fi
    # Try GNU date first (Linux)
    if date -d "@$ts" +"%Y-%m-%d" 2>/dev/null; then
        return
    fi
    # Fall back to BSD date (macOS)
    if date -r "$ts" +"%Y-%m-%d" 2>/dev/null; then
        return
    fi
    # Last resort
    echo "unknown"
}

# Check when docs were last updated (get timestamps for proper comparison)
DOCS_MODIFIED_TS=$(git log -1 --format="%ct" -- docs/ 2>/dev/null || echo "0")
SPEC_CREATED_TS=$(git log -1 --format="%ct" -- specs/ 2>/dev/null || echo "0")

if [ "$DOCS_MODIFIED_TS" -lt "$SPEC_CREATED_TS" ]; then
    DOCS_MODIFIED=$(format_timestamp "$DOCS_MODIFIED_TS")
    SPEC_CREATED=$(format_timestamp "$SPEC_CREATED_TS")
    echo "⚠ Documentation not updated since spec creation"
    echo "   Docs last updated: $DOCS_MODIFIED"
    echo "   Spec created: $SPEC_CREATED"
fi
```

**Decision logic:**
```
if docs_outdated:
    ⚠ Documentation may be outdated
    Prompt: "Update docs first? (yes/no/cancel)"
    if user says yes:
        Guide user to update docs
        exit 0
    if user says cancel:
        exit 0
```

### 2.3 Check Spec Validation

Check if specs have been validated:
```bash
# Check for validation markers in spec files
SPEC_FILES=$(find specs/ -name "spec-${issue_number}-*.md" 2>/dev/null)

if [ -n "$SPEC_FILES" ]; then
    # Check if validation section exists
    VALIDATED=$(grep -l "## Validation" $SPEC_FILES)
    if [ -z "$VALIDATED" ]; then
        echo "⚠ Specs not validated"
    fi
fi
```

**Decision logic:**
```
if specs_not_validated:
    ⚠ Specs not validated
    Note: This is non-blocking, just a warning
```

### 2.4 Confirm with User

Show summary and ask for confirmation:
```
Ready to archive issue #{{issue_number}}

Status:
{{issue_status}}
{{docs_status}}
{{spec_status}}

Continue with archive? (y/n)
```

Wait for user response. If "n", exit 0.

## Step 3: Archive Specifications

**Skip this step if `skip_specs` is true.**

Use @agent-fractary-spec:spec-manager to archive specs:
```
{
  "operation": "archive",
  "issue_number": "{{issue_number}}",
  "skip_checks": true
}
```

Expected result:
```json
{
  "success": true,
  "specs_archived": 2,
  "spec_urls": [
    {"filename": "spec-123-feature.md", "url": "https://...", "size": "12.3 KB"},
    {"filename": "spec-123-api.md", "url": "https://...", "size": "8.7 KB"}
  ],
  "index_updated": true
}
```

**Error handling:**
```
if spec_archive_fails:
    ✗ Spec archive failed
    Error: {error_message}

    This is a critical failure. Cannot proceed with log archival.

    Recovery:
    1. Check cloud storage configuration
    2. Verify network connectivity
    3. Retry: /fractary-faber:archive {{issue_number}}

    exit 1
```

**On success:**
```
✓ Specs archived
  - Uploaded {{count}} specifications
  - Total size: {{total_size}}
  - Index updated
```

## Step 4: Archive Logs

**Skip this step if `skip_logs` is true.**

Use @agent-fractary-logs:log-manager to archive logs:
```
{
  "operation": "archive",
  "issue_number": "{{issue_number}}",
  "skip_checks": true
}
```

Expected result:
```json
{
  "success": true,
  "logs_archived": 4,
  "log_urls": [
    {"type": "session", "filename": "session-123.log", "url": "https://...", "size": "45.2 KB"},
    {"type": "build", "filename": "build-123.log", "url": "https://...", "size": "23.1 KB"},
    {"type": "test", "filename": "test-123.log", "url": "https://...", "size": "18.9 KB"},
    {"type": "debug", "filename": "debug-123.log.gz", "url": "https://...", "size": "102.4 KB"}
  ],
  "compressed": 1,
  "index_updated": true
}
```

**Error handling:**
```
if log_archive_fails:
    ⚠ Log archive failed (specs already archived)
    Error: {error_message}

    Specs were successfully archived, but log archival failed.

    Recovery:
    1. Manual retry: /fractary-logs:archive {{issue_number}}
    2. Or retry full archive: /fractary-faber:archive {{issue_number}} --skip-specs

    Continue with GitHub updates anyway? (y/n)
```

**On success:**
```
✓ Logs archived
  - Uploaded {{count}} logs ({{types}})
  - Compressed: {{compressed_count}} large logs
  - Total size: {{total_size}}
  - Index updated
```

## Step 5: GitHub Updates

### 5.1 Comment on Issue

Use @agent-fractary-work:work-manager to post comment:
```
{
  "operation": "comment",
  "issue_number": "{{issue_number}}",
  "comment": "{{formatted_archive_comment}}"
}
```

**Comment format:**
```markdown
✅ **FABER Workflow Archived**

All artifacts for this work have been permanently archived!

**Specifications** ({{spec_count}}):
{{#each spec_urls}}
- [{{filename}}]({{url}}) ({{size}})
{{/each}}

**Logs** ({{log_count}}):
{{#each log_urls}}
- [{{type}}: {{filename}}]({{url}}) ({{size}})
{{/each}}

**Total Size**: {{total_size}} (compressed)
**Archived**: {{timestamp}}

These artifacts are searchable via:
- `/fractary-spec:read {{issue_number}}`
- `/fractary-logs:read {{issue_number}}`
- `/fractary-logs:search "query"`
```

### 5.2 Comment on PR (if exists)

If PR URL exists from pre-checks:
```
{
  "operation": "comment-pr",
  "pr_number": "{{pr_number}}",
  "comment": "{{formatted_pr_comment}}"
}
```

**PR Comment format:**
```markdown
📦 **Artifacts Archived**

Specifications and logs for this PR have been archived to cloud storage.
See issue #{{issue_number}} for complete archive details.
```

**Error handling:**
```
if github_comment_fails:
    ⚠ Failed to comment on GitHub
    Error: {error_message}

    Archive succeeded, but GitHub comment failed.
    You may want to manually comment with the archive URLs.

    Continue anyway (archive is complete).
```

**On success:**
```
✓ GitHub updated
  - Commented on issue #{{issue_number}}
  {{#if pr_exists}}
  - Commented on PR #{{pr_number}}
  {{/if}}
```

## Step 6: Local Cleanup

Clean up local files and commit index changes:

```bash
# Stage archive index updates
git add specs/.archive-index.json logs/.archive-index.json 2>/dev/null

# Check if there are actually changes to commit
if git diff --cached --quiet; then
    echo "✅ Archive indexes (no changes to commit)"
else
    # Commit archive index updates (must succeed before considering cleanup complete)
    if ! git commit -m "Archive artifacts for issue #{{issue_number}}"; then
        echo "❌ Failed to commit archive index updates"
        echo ""
        echo "Archives uploaded successfully, but local cleanup incomplete."
        echo "Manual cleanup required:"
        echo "  git add specs/.archive-index.json logs/.archive-index.json"
        echo "  git commit -m 'Archive cleanup for issue #{{issue_number}}'"
        exit 1
    fi
    echo "✅ Archive indexes committed"
fi
```

**Note**: Archived files are removed by fractary-spec and fractary-logs agents during their archive operations (Steps 3 and 4), not in this cleanup step. This step only commits the index updates.

**On success:**
```
✓ Local cleanup
  - Archived files removed (by spec/log managers)
  - Archive indexes committed
```

## Step 7: Return Summary

Output completion message and return structured result:

```
✅ COMPLETED: Archive Workflow Skill
Issue: #{{issue_number}}
───────────────────────────────────────
Results:
- Specs archived: {{spec_count}}
- Logs archived: {{log_count}}
- Total size: {{total_size}}
- GitHub updated: {{github_updated}}
- Local cleaned: {{local_cleaned}}

Next: Archive complete! All artifacts permanently stored.
───────────────────────────────────────
```

Return structured result to workflow-manager:
```json
{
  "success": true,
  "issue_number": "{{issue_number}}",
  "specs_archived": {{spec_count}},
  "logs_archived": {{log_count}},
  "total_size_bytes": {{total_size}},
  "archive_urls": {
    "specs": [...],
    "logs": [...]
  },
  "local_cleaned": true,
  "github_updated": true
}
```

</WORKFLOW>

<ERROR_HANDLING>

## Exit Code Standards

To maintain consistency with the archive command, use these exit codes:

- **Exit 0**: Success or user cancellation
- **Exit 1**: Archive operation failures (spec/log upload, GitHub operations)
- **Exit 2**: Invalid parameters (should not occur in skill, handled by command)
- **Exit 3**: Configuration errors (missing .faber.config.toml)
- **Exit 4**: Pre-check failures (issue not closed, validation failures)

## Pre-Check Failures
- **Issue not found** (exit 4): Exit with clear message, suggest verifying issue number
- **User cancels** (exit 0): Exit gracefully
- **Pre-checks fail** (exit 4): If not forced, exit when warnings are not accepted
- **Configuration missing** (exit 3): Exit with message to run /fractary-faber:init

## Archive Failures
- **Spec archive fails** (exit 1): STOP immediately, don't proceed to logs
- **Log archive fails** (exit 1): Warn about partial failure, specs already safe
- **Network errors** (exit 1): Retry up to 3 times with exponential backoff before failing
- **Cleanup fails** (exit 1): Archives succeeded but local cleanup incomplete
- **Partial success**: Clearly show what succeeded/failed with appropriate exit code

## GitHub Failures
- **Comment fails**: Warn but continue (archive still succeeded, don't exit)
- **Authentication fails** (exit 1): Show auth instructions and fail

## Recovery Guidance
Always provide clear next steps:
- What to retry
- What succeeded (don't need to redo)
- Manual commands if needed
- Appropriate exit code for each failure scenario

</ERROR_HANDLING>

<COMPLETION_CRITERIA>

Archive is complete when:
- ✓ Pre-checks passed or bypassed (--force)
- ✓ Specs uploaded to cloud (unless --skip-specs)
- ✓ Logs uploaded to cloud (unless --skip-logs)
- ✓ Archive indexes updated
- ✓ GitHub issue commented (or warned if failed)
- ✓ GitHub PR commented if exists (or warned if failed)
- ✓ Local files removed
- ✓ User notified of completion
- ✓ Structured result returned

</COMPLETION_CRITERIA>

<OUTPUTS>

Return structured JSON result to workflow-manager:

```json
