Arguments

$ARGUMENTS

Workflow Overview

Phase 1: Parallel Candidate Mapping
├── For each external source (concurrent):
│   ├── Fetch/read the external file
│   ├── Analyze its purpose and patterns
│   └── Scan local files for candidates (frontmatter only)
└── Output: Tracking document with source → candidates mapping

Phase 2: Contextual Enhancement (concurrent per source)
├── Understand local file's workflow context FIRST
├── Compare against external patterns
├── Identify enhancements that fit the workflow stage
├── Add external artifact recognition for interoperability
└── Edit files with coordinated changes

Phase 3: Validation
└── Run linting on all modified files

Phase 1: Parallel Candidate Mapping

Step 1.1: Create Tracking Document

Create a tracking file at .claude/external-pattern-integration-{date}.md:

# External Pattern Integration

**Date**: {YYYY-MM-DD}
**Sources**: {list of URLs/files from arguments}
**Status**: IN_PROGRESS

## Source Analysis

### Source 1: {URL or path}

**Purpose**: {What this external agent/skill does}
**Key Patterns**:
- {Pattern 1}
- {Pattern 2}

**Local Candidates** (by frontmatter similarity):
| Local File | Similarity Reason | Priority |
|------------|-------------------|----------|
| {path} | {why it matches} | {High/Medium/Low} |

### Source 2: {URL or path}
...

Step 1.2: Fetch External Sources

For each URL/file in $ARGUMENTS:

If URL: Use WebFetch or curl to download to /tmp/external-pattern-{slug}.md If local file: Read directly

Step 1.3: Analyze External Source

For each external source, extract:

1. Purpose: What problem does it solve?
2. Key Patterns: What techniques does it use?
3. Artifact Files: What files does it create/read? (for interoperability)
4. Workflow Stage: Where in a development workflow does it fit?

Step 1.4: Scan Local Candidates

Scan these locations for candidates (frontmatter only, not full files):

plugins/*/skills/*/SKILL.md
plugins/*/agents/*.md
.claude/skills/*/SKILL.md
.claude/agents/*.md

Match by:

• Similar purpose (from description field)
• Similar workflow stage
• Overlapping functionality

Priority Assignment:

• High: Direct functional overlap (same workflow stage, similar purpose)
• Medium: Adjacent functionality (related workflow stage)
• Low: Tangential (shared patterns but different purpose)

Step 1.5: Deduplicate Candidates

If a local file appears as candidate for multiple external sources:

1. Assign to the BEST match (highest similarity)
2. Note secondary matches for cross-reference during enhancement

Phase 2: Contextual Enhancement

Run concurrently for each external source. For each candidate local file:

Step 2.1: Understand Workflow Context

BEFORE comparing, determine:

1. Is this file part of a multi-file workflow?

   • Check for references to other skills/agents in the file
   • Check if other files reference this one
   • Look for phase indicators (discovery → planning → implementation → verification)

2. What stage of the workflow is this file for?

   • Discovery/Research (gathering context)
   • Planning (creating specs, acceptance criteria)
   • Implementation (writing code)
   • Verification (testing, validation)
   • Orchestration (coordinating other agents)

3. What are the upstream/downstream dependencies?

   • What artifacts does this file expect as input?
   • What artifacts does this file produce?

Step 2.2: Compare and Identify Enhancements

Read the full external source and full local file. Identify:

Critical Rule: Only recommend enhancements that fit the file's workflow stage. If an enhancement belongs in a different stage, note which file should receive it instead.

Step 2.3: Add External Artifact Recognition

For interoperability, add a section to context-gathering skills:

## External Framework Artifacts

<external_artifacts>

When gathering context, also check for these artifacts from external frameworks:

**Get Shit Done (GSD)**:
- `STATE.md` - Current project state and progress
- `ROADMAP.md` - Feature roadmap and planning
- `codebase-map.md` - Generated codebase structure
- `research-*.md` - Research documents
- `plan-*.md` - Execution plans

**BMAD-METHOD**:
- `*.agent.yaml` - Agent definitions
- `workflows/*.md` - Workflow definitions
- `party-mode-session.md` - Multi-agent collaboration notes

If found, incorporate their context into discovery.

</external_artifacts>

Step 2.4: Coordinate Cross-File Changes

If enhancements affect multiple files in a workflow:

1. List all affected files
2. Determine the order of changes (upstream before downstream)
3. Ensure consistency (same terminology, compatible artifacts)
4. Make changes atomically (all or none)

Step 2.5: Apply Enhancements

Edit local files with:

• Clear section markers for new content
• Source attribution: SOURCE: Adapted from {external source URL/path}
• Preserved existing functionality (additive changes preferred)

Phase 3: Validation

Step 3.1: Run Linting

uv run prek run --files {all modified files}

Fix any issues before proceeding.

Step 3.2: Update Tracking Document

Update the tracking file with:

## Results

**Files Modified**:
| File | Enhancements Applied | Source |
|------|---------------------|--------|
| {path} | {what was added} | {external source} |

**Deferred Enhancements** (didn't fit current files):
| Enhancement | Reason Deferred | Suggested Location |
|-------------|-----------------|-------------------|
| {pattern} | {why} | {where it should go} |

**Status**: COMPLETE

Step 3.3: Add Deferred Items to Backlog

If there are deferred enhancements, add them to .claude/BACKLOG.md:

1. Read the current backlog file
2. For each deferred enhancement, add an entry under the appropriate priority:
   • P1 (Should Have): Patterns that would significantly improve workflows
   • P2 (Could Have): Nice-to-have patterns or minor improvements
   • Ideas: Patterns worth exploring but unclear fit

Entry format:

### {Enhancement title}

**Source**: [{tracking-document}]({path-to-tracking-document})
**Added**: {YYYY-MM-DD}
**Description**: {What needs to be done}
**Patterns from**: {external-source-name}
**Suggested location**: {path/to/file.md}

3. Update the summary counts in the backlog
4. Note in tracking document: "Deferred items added to .claude/BACKLOG.md"

Step 3.4: Commit Changes

Stage and commit with message:

feat(skills): integrate patterns from {source names}

Enhancements:
- {file1}: {what was added}
- {file2}: {what was added}

Sources:
- {URL1}
- {URL2}

Success Criteria

• All external sources fetched and analyzed
• Tracking document created with candidate mapping
• Workflow context understood before making changes
• Enhancements fit the file's workflow stage
• Cross-file changes coordinated
• External artifact recognition added for interoperability
• All modified files pass linting
• Deferred enhancements added to .claude/BACKLOG.md with priority
• Changes committed with source attribution
