Ecosystem Health

MANDATORY: docs-management Delegation

CRITICAL: This skill follows the anti-duplication principle. ALL component details MUST be queried from docs-management at runtime.

What This Skill Hardcodes (Static - Changes Rarely)

/audit-*

What MUST Be Delegated (Dynamic - Changes With Releases)

docs-management: cli-reference.md CLI flags

docs-management: settings.md environment variables

docs-management: iam.md authentication methods

docs-management: iam.md permission modes

docs-management: setup.md cloud providers

docs-management: third-party-integrations.md IDE

Delegation Rules

1. NEVER use hardcoded lists for CLI flags, env vars, auth methods, cloud providers, IDE integrations, permission modes, or any frequently-changing data
2. ALWAYS query docs-management when you need component details
3. Use claude-code-guide agent for live verification during

   --discover

   and

   --check

   modes
4. If docs-management returns empty, that's a signal to check if the component still exists

Query Patterns for docs-management

# Tier 3: Environment & CLI
"cli-reference.md CLI flags"              → Get current CLI flags list
"settings.md environment variables"       → Get current env vars list

"iam.md configuring permissions"          → Get permission rule patterns
"iam.md credential management"            → Get credential features

# Tier 5: Session & Runtime
"cli-reference.md session features"       → Get session features (resume, checkpoints)
"security.md sandbox configuration"       → Get sandbox settings

# Tier 6: Integration
"third-party-integrations.md IDE"         → Get IDE integrations list
"setup.md cloud providers"                → Get cloud provider list
"common-workflows.md CI/CD"               → Get CI/CD platforms

# Changelog for change categorization
"CHANGELOG recent changes"                → Get changelog entries

Overview

This skill tracks Claude Code ecosystem health across ALL extensibility points - not just plugin components. It monitors 27 component types across 6 tiers.

Schema v2.2 introduces the Tiered Validation Model for changelog-triggered audit staleness:

• Minor changes (features, deprecations) → Targeted keyword validation (cheap)
• Major changes (behavior_change, security) → Full audit required (no shortcuts)
• Bugfixes → No validation needed

This approach provides 60-96% token savings while maintaining strict accuracy requirements.

Tiered Validation Model (v2.2)

Schema v2.2 introduces a three-tier validation model that automatically invalidates audits when changelog changes affect components, while using the most token-efficient validation method appropriate for each change type.

Change Severity Classification

feature

deprecation

bugfix

behavior_change

security

Validation Tiers

Tier 1: Targeted Validation (Minor Changes)

For

feature

deprecation

• Method: Grep-based keyword verification
• Evidence: File path, line number, matched text
• Cost: ~100-500 tokens per change
• Status on pass:

  VALIDATED

Algorithm:

1. Load validation spec from granular_changelog change entry
2. For each keyword in validation.keywords:
   a. Run grep against target_skill directory
   b. If match found, record evidence (file, line, match text)
3. If matches >= required_matches:
   a. Set validation_result.validated = true
   b. Set confidence based on match count:
      - 1 match = "medium"
      - 2+ matches = "high"
4. Update component_coverage validation tracking

Tier 2: Full Audit (Major Changes)

For

behavior_change

security

• Method: Spawns auditor agent(s)
• Audit command: Specified in validation.audit_command
• Cost: ~3,000-8,000 tokens
• Status on pass:

  AUDITED

Important: Major changes cannot be validated via targeted validation. The system must enforce this - no shortcuts.

Tier 3: Periodic Review

Regardless of validation status:

• Threshold: >90 days since last full audit
• Action: Triggers full audit
• Rationale: Ensures nothing drifts over time

Validation Spec Schema (v2.2)

Each change in

granular_changelog

validation:
  method: "keyword_check"           # keyword_check | full_audit | manual | none
  target_skill: "hook-management"   # Which skill to validate (null for memory files)
  keywords:                         # Manual list - NEVER auto-extracted
    - "additionalContext"
    - "additional context"
    - "PreToolUse.*additionalContext"  # Regex supported
  required_matches: 1               # How many keywords must match
  reason: "..."                     # Optional explanation (esp. for method: none)

# For full_audit method:
validation:
  method: "full_audit"
  target_skill: "permission-management"
  audit_command: "/audit-settings"
  reason: "Security fix - targeted validation insufficient"

Validation Result Schema

After validation runs, results are recorded:

validation_result:
  validated: true                   # Did validation pass?
  validated_date: "2026-01-16"      # When validated
  evidence:                         # For keyword_check method
    - file: "path/to/file.md"
      line: 142
      match: "matched text"
  audit_performed: true             # For full_audit method
  audit_date: "2026-01-12"          # When audit was run
  confidence: "high"                # high | medium | low

Status Calculation (Conservative)

Component status is determined by this priority order (first match wins):

pending_major_changes

NEEDS AUDIT

pending_minor_changes

NEEDS VALIDATION

days_since(last_audit) > 90

STALE

validation_version == latest AND validation_confidence == "high"

VALIDATED

last_audit

OK

UNKNOWN

Conservative Rule: If ANY doubt exists, escalate to higher requirement.

Validation Accuracy Rules (CRITICAL)

The system must NEVER report "validated" unless certain. These rules are non-negotiable.

Rule 1: Keyword Matches Must Be Contextually Correct

❌ Finding "context" when looking for "context: fork" is NOT a match
✅ Must match exact keyword or regex pattern

Rule 2: Multiple Evidence Preferred

validation_failed: true

confidence: "medium"

confidence: "high"

Rule 3: Human Confirmation for Edge Cases

If confidence is

"low"

• Flag for manual review
• Do NOT auto-mark as validated
• Include in

  --apply

  output for user decision

Rule 4: Evidence is Mandatory

• No validation without captured evidence
• Evidence must include file path and line number
• Empty evidence = validation failed

Rule 5: Major Changes Cannot Use Targeted Validation

❌ security change → keyword_check (FORBIDDEN)
❌ behavior_change → keyword_check (FORBIDDEN)
✅ security change → full_audit (REQUIRED)
✅ behavior_change → full_audit (REQUIRED)

The system must reject attempts to use targeted validation for major changes.

The skill provides:

1. Parsing changelogs to identify new features and changes
2. Tracking audit coverage across all 27 component types
3. Documentation coverage for non-auditable components (queried from docs-management)
4. Identifying pending updates needed for compliance
5. Orchestrating audits efficiently (avoiding token waste)
6. Helping apply updates from new Claude Code versions

When to Use This Skill

Use this skill when:

• Checking if ANY Claude Code extensibility component is up-to-date
• Getting an overview of audit coverage and staleness across all tiers
• Tracking documentation coverage for non-auditable components
• Planning which audits to run (token-efficient approach)
• Applying updates after Claude Code releases new versions
• Preparing a plugin release
• Detecting new/deprecated Claude Code features

Tracking File

Location:

.claude/ecosystem-health.yaml

This file persists ecosystem health state across sessions. It stores audit metadata ONLY - not component details (which are delegated to docs-management).

Schema v2.1 Structure:

schema_version: "2.1"

  date: "YYYY-MM-DD"
  claude_code_version: "X.Y.Z"
  changelog_hash: "sha256:..."

Key Design Decision: The tracking file does NOT contain

tracked_*

Changelog Access

MANDATORY: Access changelog via

docs-management

Doc ID:

raw-githubusercontent-com-anthropics-claude-code-refs-heads-main-CHANGELOG

Access pattern:

python plugins/claude-ecosystem/skills/docs-management/scripts/core/find_docs.py \
  content raw-githubusercontent-com-anthropics-claude-code-refs-heads-main-CHANGELOG

Version Extraction

Parse changelog for version entries:

Pattern: ^##\s*\[?(\d+\.\d+\.\d+)\]?
Examples:
  "## 2.1.3" → version 2.1.3
  "## [2.1.0]" → version 2.1.0

Change Categorization

Map changelog keywords to component types across all 6 tiers.

IMPORTANT: Do NOT use hardcoded keyword lists. Query docs-management for current keywords via the index, then match changelog entries against those keywords.

Categorization Algorithm

1. Query docs-management index for keyword lists by doc section
2. For each changelog entry: a. Match against keywords from relevant doc sections b. Assign to tier(s) based on which docs matched c. Record affected components

Tier-to-Doc Mapping

For detailed categorization patterns, see references/change-categories.md.

Modes of Operation

Status Mode (Default / --status)

Shows current ecosystem health without running audits. Displays all 6 tiers.

Algorithm:

1. Load tracking file (or show "never checked" if missing)
2. Read audit data for each component in all 6 tiers
3. Calculate staleness (days since last audit/review)
4. Show summary tables by tier with recommendations

Check Mode (--check)

Compares current changelog against last check. Identifies changes across all tiers.

Algorithm:

1. Load tracking file
2. Fetch changelog via docs-management
3. Compute changelog hash
4. If hash differs from tracked hash: a. Parse new versions since last check b. Query docs-management for current keyword mappings c. Categorize changes by tier d. Add to pending_updates with tier info
5. Spawn claude-code-guide agent for live verification of new features
6. Update tracking file
7. Report findings by tier

Audit Mode (--audit [type])

Runs audits intelligently. Only applies to Tier 2 components (automated audits).

Without type argument: Audits all stale/never-audited Tier 2 components With type argument: Audits only specified type

Priority Order:

1. Never audited (Priority 1)
2. Affected by recent changelog changes (Priority 2)
3. Stale >90 days (Priority 3)

Batching:

• Max 3 audits per batch
• Present results between batches
• Allow user to continue or stop

Audit Command Mapping (Tier 2 Only):

/audit-skills

/audit-agents

/audit-commands

/audit-hooks

/audit-mcp

/audit-memory

/audit-plugins

/audit-settings

/audit-output-styles

/audit-statuslines

/audit-rules

/audit-lsp

Compliance Audits (Cross-Cutting):

/audit-docs-delegation

/audit-agent-consolidation

Doc Coverage Mode (--doc-coverage)

Tracks documentation coverage for non-auditable components (Tiers 3-6).

Algorithm:

1. Load tracking file
2. For each documentation-tracked component: a. Query docs-management for official doc section b. Extract current feature list from doc content c. Report coverage status
3. No hardcoded lists - all data comes from docs-management queries

Note: Coverage is always based on current docs-management content. There's no "tracked list" to compare against - docs-management IS the source of truth.

Apply Mode (--apply)

Interactive mode to apply pending updates.

For each pending update:

1. Show what changed in Claude Code
2. Show affected tiers
3. Load relevant development skill
4. Search codebase for affected patterns
5. Present affected files
6. Ask user for action:
   • Show detailed changes
   • Apply changes automatically
   • Skip this update
   • Mark as already applied

Since Mode (--since <version>)

Shows all changes since a specific version, organized by tier.

Algorithm:

1. Fetch changelog
2. Parse entries from specified version to current
3. Query docs-management for keyword mappings
4. Categorize all changes by tier
5. Present summary by tier

Overlap Mode (--overlap)

Detects plugin overlaps, redundancy, and consolidation opportunities.

Algorithm:

1. Enumerate all plugins:

   • Glob all

     plugins/*/

     directories
   • Read each plugin's manifest and README

2. Extract component names:

   • For each plugin, extract skill names from

     skills/*/SKILL.md

   • Extract command names from

     commands/*.md

   • Extract agent names from

     agents/*.md

3. Detect duplicates:

   • Find skill names that appear in multiple plugins
   • Find command names that appear in multiple plugins
   • Find agent names that appear in multiple plugins

4. Semantic overlap analysis:

   • Compare plugin descriptions for >70% semantic similarity
   • Compare skill descriptions within same domain
   • Flag plugins covering same methodology

5. Published standard detection:

   • For each plugin, check if methodology is a published standard
   • Query perplexity: "Is {methodology} a published standard?"
   • Published standards: ISO 25010, CRISP-DM, BABOK, Kimball, Design Thinking, TOGAF, WCAG, etc.
   • Flag plugins that ONLY wrap published standards with no unique value

6. Generate overlap report:

## Plugin Overlap Analysis

**Duplicate Components Found:**

| Component | Type | Plugins |
| --------- | ---- | ------- |
| adr-management | skill | enterprise-architecture, documentation-standards |
| journey-mapping | skill | business-analysis, requirements-elicitation |

**Semantic Overlaps:**

| Plugin A | Plugin B | Overlap % | Domain | Status |
| -------- | -------- | --------- | ------ | ------ |
| ~~contract-testing~~ | test-strategy | 85% | Testing | ✅ CONSOLIDATED (v2.0) |
| ~~observability-planning~~ | ~~quality-attributes~~ | 70% | NFRs | ✅ BOTH REMOVED (v2.0) |

**Published Standard Plugins (Consolidation Candidates):**

| Plugin | Methodology | Standard Type | Recommendation | Status |
| ------ | ----------- | ------------- | -------------- | ------ |
| ~~quality-attributes~~ | ISO 25010 | International Standard | REMOVE | ✅ REMOVED (v2.0) |
| ~~ai-ml-planning~~ | CRISP-DM | Industry Framework | REMOVE | ✅ REMOVED (v2.0) |
| ~~data-architecture~~ | Kimball | Published Methodology | REMOVE | ✅ REMOVED (v2.0) |

**Consolidation Completed (v2.0):**

1. **~~contract-testing~~ → test-strategy** - DONE: `compatibility-analyzer` agent moved
2. **8 published standard plugins** - REMOVED: MCP research replaces them
3. **content-management-system** - KEPT: unique composition patterns

7. Update tracking file:
   • Record overlap analysis date
   • Store consolidation recommendations
   • Track which overlaps have been resolved

Overlap Status in ecosystem-health.yaml:

plugin_overlap:
  last_analysis: "2026-01-17"
  total_plugins: 35
  duplicate_components:
    - component: "adr-management"
      type: "skill"
      plugins: ["enterprise-architecture", "documentation-standards"]
      resolution: "pending" | "resolved" | "intentional"
  published_standard_plugins:
    - plugin: "quality-attributes"
      methodology: "ISO 25010"
      recommendation: "remove"
      status: "pending" | "removed" | "kept_with_justification"
  consolidation_candidates:
    - source: "contract-testing"
      target: "test-strategy"
      assets_moved: ["compatibility-analyzer agent"]
      status: "completed"  # v2.0 consolidation

Discover Mode (--discover)

Scans official documentation to detect ecosystem drift across ALL 6 tiers.

Algorithm:

1. Query docs-management for ALL relevant doc sections:

   • Tier 1: settings.md, iam.md, memory.md
   • Tier 2: plugins-reference.md, skills.md, hooks.md, etc.
   • Tier 3: settings.md#environment-variables, cli-reference.md, iam.md#permission-modes
   • Tier 4: iam.md#authentication-methods, iam.md#configuring-permissions
   • Tier 5: cli-reference.md, security.md
   • Tier 6: third-party-integrations.md, setup.md, common-workflows.md

2. Spawn claude-code-guide agent for live web verification of:

   • Recent changelog entries
   • New feature announcements
   • Deprecated features

3. Build detected components list by tier:

   • Extract features from docs-management responses
   • Compare to tracked component types (27 total)
   • Identify gaps

4. Report findings with evidence:

   • Show doc_id or changelog version as source
   • Provide recommendation (add tracking, update name, merge)
   • Indicate affected tier

Quick Decision Tree

What do you want to do?

1. Get overview of all Claude Code extensibility → Use Status Mode (default)
2. Check for Claude Code updates → Use Check Mode (

   --check

   )
3. Run audits for Tier 2 plugin components → Use Audit Mode (

   --audit

   )
4. Check documentation coverage for Tiers 3-6 → Use Doc Coverage Mode (

   --doc-coverage

   )
5. Apply pending updates → Use Apply Mode (

   --apply

   )
6. See changes since version X → Use Since Mode (

   --since X.Y.Z

   )
7. Detect plugin overlaps and redundancy → Use Overlap Mode (

   --overlap

   )
8. Check for new/changed components in any tier → Use Discover Mode (

   --discover

   )

Delegation Pattern

This skill delegates to specialized skills for domain-specific guidance:

ecosystem-health
    ├── docs-management (MANDATORY - changelog, official docs for all tiers)
    ├── claude-code-guide (live verification during --discover and --check)
    │
    ├── Tier 1 & 2 - Settings/Memory
    │   ├── settings-management
    │   └── memory-management
    │
    ├── Tier 2 - Plugin Components
    │   ├── skill-development
    │   ├── subagent-development
    │   ├── command-development
    │   ├── hook-management
    │   ├── mcp-integration
    │   ├── plugin-development
    │   ├── output-customization
    │   └── status-line-customization
    │
    ├── Tier 3-4 - Auth/Environment
    │   ├── settings-management
    │   ├── permission-management
    │   └── enterprise-security
    │
    ├── Tier 5 - Session/Runtime
    │   └── sandbox-configuration
    │
    └── Tier 6 - Integration (documentation tracking only)

Token Efficiency

Goal: Minimize tokens while maintaining coverage.

Strategies:

1. Skip recently-audited components (use tracking file)
2. Prioritize by changelog impact (audit what changed)
3. Batch audits (max 3 at a time)
4. Progressive disclosure (load references only when needed)
5. Delegate to docs-management (no local caches to maintain)
6. Use claude-code-guide only when live verification needed

Expected savings: 60-80% compared to running all audits blindly.

Schema Migration

The skill handles migration between schema versions:

v1.0 → v2.0: Tiered organization v2.0 → v2.1: Delegation pattern (remove hardcoded lists)

Migration algorithm:

1. Detects schema version
2. Creates backup at

   .claude/ecosystem-health.yaml.backup

3. Preserves existing audit data (last_audit, pass_rate, components_audited)
4. Removes deprecated fields (tracked_*, file_patterns)
5. Writes new schema version

Scenario 3: Smart Audit (Tier 2)

Query:

/ecosystem-health --audit

Scenario 4: Documentation Coverage (Delegated)

Query:

/ecosystem-health --doc-coverage

1. Queries docs-management for each Tier 3-6 doc section
2. Reports coverage based on current docs content
3. NO comparison against hardcoded lists Success: Coverage reported from live docs-management queries

Scenario 5: Component Discovery (with claude-code-guide)

Query:

/ecosystem-health --discover

1. Queries docs-management for ALL tier doc sections
2. Spawns claude-code-guide for live web verification
