SkillForge 5.2 - Intelligent Skill Router, Advisor & Creator

Analyzes ANY input to find, improve, or create the right skill. It can also proactively surface evidence-backed skill suggestions through the Context Skill Advisor.

---

Quick Start

Any input works. SkillForge will intelligently route to the right action:

# These all work - SkillForge figures out what you need:

SkillForge: create a skill for automated code review
→ Creates new skill (after checking no duplicates exist)

help me debug this TypeError
→ Recommends ErrorExplainer skill (existing)

improve the testgen skill to handle React components better
→ Enters improvement mode for TestGen

do I have a skill for database migrations?
→ Recommends DBSchema, database-migration skills

TypeError: Cannot read property 'map' of undefined
→ Routes to debugging skills (error detected)

---

Triggers

Creation Triggers

• SkillForge: {goal} - Full autonomous skill creation
• create skill - Natural language activation
• design skill for {purpose} - Purpose-first creation
• ultimate skill - Emphasize maximum quality
• skillforge --plan-only - Generate specification without execution

Routing Triggers (NEW in v4.0)

• {any input} - Analyzes and routes automatically
• do I have a skill for - Searches existing skills
• which skill / what skill - Recommends matching skills
• improve {skill-name} skill - Enters improvement mode
• help me with / I need to - Detects task and routes

Proactive Advisor Triggers (NEW in v5.2)

• Session start - Show pending suggestions from the Advisory Queue
• Advisor Checkpoint - Evaluate task shifts, repeated friction, and before-final moments
• Scheduled Background Advising - Run local scheduled advisor checks based on Proactivity Level
• SkillForge advice / context advisor - Inspect or manage queued suggestions

Input	Output	Quality Gate
Any input	Triage → Route → Action	Phase 0 analysis
Explicit create	New skill	Unanimous panel approval
Task/question	Skill recommendation	Match confidence ≥60%
Advisor checkpoint	Evidence-backed suggestion	Proactivity Level threshold

Production-Ready Agentic Skill

Key principles:

• Phase 0 prevents duplicates - Always checks existing skills first
• Evolution/timelessness is the core lens (score ≥ 7 required)
• Every decision includes WHY
• Zero tolerance for errors
• Autonomous execution at maximum depth
• Scripts enable self-verification and agentic operation

Tool Escalation Policy

Start with least privilege (Read, Glob, Grep, Write, Edit).

Only add higher-risk tools when explicitly required:

• Bash for deterministic local scripts that cannot be replaced with file edits
• WebFetch / WebSearch only when external facts are required
• Task only for true parallel sub-agent orchestration

---

SkillForge --improve {skill}	Enter improvement mode for existing skill
python scripts/install_skillforge.py	Configure proactive advising
bash scripts/install_workshop.sh	Install SkillForge for Claude Code, Codex, and workshop use
python scripts/context_advisor.py checkpoint --text "<context>"	Run an Advisor Checkpoint
python scripts/context_advisor.py run	Run Scheduled Background Advising and queue suggestions
python scripts/context_advisor.py list	List pending suggestions

Context Skill Advisor (NEW in v5.2)

The Context Skill Advisor produces proactive, evidence-backed suggestions without replacing explicit SkillForge routing.

Proactivity Levels

Level	Minimum Confidence	Max Surfaced	Schedule
off	N/A	0	Never
quiet	85	1 per session/day	Daily
balanced	70	2 per session, 3 per day	Every 2 hours
active	55	4 per session, 8 per day	Every 30 minutes

Install default: balanced.

Context Source Tiers

All three source tiers are enabled by default, but the advisor uses Targeted Content Access: search first, then read only narrow relevant excerpts.

Tier	Examples
Session Context	Current prompt, checkpoint text, immediate workspace state
Project Context	AGENTS.md, README.md, CONTEXT.md, package files, ADRs
Personal Context	~/kb, ~/Documents/Work, ~/Projects, GitHub repo metadata

Suggestion Shape

Every proactive suggestion includes:

• Suggested skill or New Skill Opportunity
• Why now
• 1-3 evidence items
• Confidence band and component scores
• Action: use_existing, compose_skills, improve_existing, or create_new
• User choices: use, snooze, dismiss, never for this project
• Sensitivity note when Personal Context contributed

SkillForge does not auto-invoke suggested skills. Suggestions become Confirmed Skill Use only after user confirmation or explicit host direction.

Advisor Commands

# Configure global defaults and print the checkpoint integration snippet
python scripts/install_skillforge.py

# One-command workshop install for Claude Code and Codex
curl -fsSL https://raw.githubusercontent.com/tripleyak/SkillForge/main/scripts/install_workshop.sh | bash

# Configure a different Proactivity Level
python scripts/install_skillforge.py --proactivity-level quiet

# Add a project override
python scripts/install_skillforge.py --project-override /path/to/project --proactivity-level active

# Run a checkpoint from the active agent session
python scripts/context_advisor.py checkpoint --cwd "$PWD" --text "<brief current context>"

# Run scheduled advising and write to the Advisory Queue
python scripts/context_advisor.py run --cwd "$PWD"

# Manage queued advice
python scripts/context_advisor.py list
python scripts/context_advisor.py use <suggestion-id>
python scripts/context_advisor.py snooze <suggestion-id> --hours 24
python scripts/context_advisor.py dismiss <suggestion-id>
python scripts/context_advisor.py never-project <suggestion-id>

Configuration

Global config lives at ~/.config/skillforge/config.json.

Project overrides live at .skillforge/config.json.

Precedence: project override → global config → built-in default balanced.

Advisor state lives at ~/.local/share/skillforge/advisor_state.json.

Queued suggestions live at ~/.local/share/skillforge/advice.jsonl.

Decision Actions

Action	When	Result
USE_EXISTING	Match ≥80%	Recommends existing skill(s) to invoke
IMPROVE_EXISTING	Match 50-79%	Loads skill and enters enhancement mode
CREATE_NEW	Match <50%	Proceeds to Phase 1 (Deep Analysis)
COMPOSE	Multi-domain	Suggests skill chain via SkillComposer
CLARIFY	Ambiguous or duplicate	Asks user to clarify intent

Triage Script

# Run triage on any input
python scripts/triage_skill_request.py "help me debug this error"

# JSON output for automation
python scripts/triage_skill_request.py "create a skill for payments" --json

# Examples:
python scripts/triage_skill_request.py "TypeError: Cannot read property 'map'"
# → USE_EXISTING: Recommends ErrorExplainer (92%)

python scripts/triage_skill_request.py "create a skill for code review"
# → CLARIFY: CodeReview skill exists (85%), create anyway?

python scripts/triage_skill_request.py "help me with API and auth and testing"
# → COMPOSE: Multi-domain, suggests APIDesign + AuthSystem + TestGen chain

Ecosystem Index

Phase 0 uses a pre-built index of all skills:

# Rebuild skill index (run periodically or after installing new skills)
python scripts/discover_skills.py

# Index location: ~/.cache/skillrecommender/skill_index.json
# Scans: ~/.codex/skills/, ~/.agents/skills/, ~/.claude/skills/, and plugin caches

Integration with Phases 1-4

• USE_EXISTING: Exits early, no creation needed
• IMPROVE_EXISTING: Loads existing skill → Phase 1 analyzes gaps → Phase 2-4 enhance
• CREATE_NEW: Full pipeline (Phase 1 → 2 → 3 → 4)
• COMPOSE: Suggests using SkillComposer instead
• CLARIFY: Pauses for user input before proceeding

Scripts Directory

Scripts enable skills to be agentic - capable of autonomous operation with self-verification.

Category	Purpose	When to Include
Validation	Verify outputs meet standards	Skill produces artifacts
Generation	Create artifacts from templates	Repeatable artifact creation
State Management	Track progress across sessions	Long-running operations
Transformation	Convert/process data	Data processing tasks
Calculation	Compute metrics/scores	Scoring or analysis

Script Requirements:

• Python 3.x with standard library only (graceful fallbacks for extras)
• Result dataclass pattern for structured returns
• Exit codes: 0=success, 1=failure, 10=validation failure, 11=verification failure
• Self-verification where applicable
• Documented in SKILL.md with usage examples

See: references/script-integration-framework.md

Hooks Integration

Skills can define lifecycle hooks for validation, logging, and safety:

---
name: secure-skill
hooks:
  PreToolUse:
    - matcher: "Bash"
      hooks:
        - type: command
          command: "./scripts/validate-input.sh"
  PostToolUse:
    - matcher: "Write"
      hooks:
        - type: command
          command: "./scripts/log-output.sh"
          once: true
  Stop:
    - hooks:
        - type: command
          command: "./scripts/cleanup.sh"
---

Hook Types:

Hook	When Triggered	Use Case
PreToolUse	Before tool execution	Input validation, security checks
PostToolUse	After tool execution	Output logging, verification
Stop	When skill completes	Cleanup, state persistence

Hook Configuration:

Field	Description
matcher	Tool name pattern to match (e.g., "Bash", "Write", "Bash(python:*)")
type	Hook type: command (shell) or prompt (Claude evaluation)
command	Shell command to execute (for type: command)
once	If true, run only once per session (default: false)

Read $TOOL_INPUT / $TOOL_OUTPUT inside hook scripts from environment variables. Do not interpolate untrusted tool payloads directly into shell command strings.

When to Use Hooks:

Scenario	Hook Type	Example
Validate script inputs	PreToolUse	Check parameters before python scripts/*.py
Log generated artifacts	PostToolUse	Record files created by Write tool
Security gate	PreToolUse	Block dangerous bash commands
Cleanup temp files	Stop	Remove intermediate artifacts

Example: Script Validation Hook

For skills with scripts, add input validation:

hooks:
  PreToolUse:
    - matcher: "Bash(python:scripts/*)"
      hooks:
        - type: command
          command: "python scripts/quick_validate.py . 2>/dev/null || true"
          once: true

---

Anti-Patterns

Avoid	Why	Instead
Duplicate skills	Bloats registry	Check existing first
Single trigger	Hard to discover	3-5 varied phrases
No verification	Can't confirm success	Measurable outcomes
Over-engineering	Complexity without value	Start simple
Missing WHY	Can't evolve	Document rationale
Invalid frontmatter	Can't package	Use allowed properties only

---

Verification Checklist

After creation:

• Frontmatter valid (only allowed properties)
• Name is hyphen-case, ≤64 chars
• Description ≤1024 chars, no < or >
• 3-5 trigger phrases defined
• Timelessness score ≥ 7
• python scripts/quick_validate.py passes
• python scripts/check_docs_safety.py passes

# Grep for similar triggers in existing SKILL.md files

Match Score	Action
>7/10	Use existing skill instead
5-7/10	Clarify distinction before proceeding
<5/10	Proceed with new skill

1B: Multi-Lens Analysis

Apply all 11 thinking models systematically:

Lens	Core Question	Application
First Principles	What's fundamentally needed?	Strip convention, find core
Inversion	What guarantees failure?	Build anti-patterns
Second-Order	What happens after the obvious?	Map downstream effects
Pre-Mortem	Why did this fail?	Proactive risk mitigation
Systems Thinking	How do parts interact?	Integration mapping
Devil's Advocate	Strongest counter-argument?	Challenge every decision
Constraints	What's truly fixed?	Separate real from assumed
Pareto	Which 20% delivers 80%?	Focus on high-value features
Root Cause	Why is this needed? (5 Whys)	Address cause not symptom
Comparative	How do options compare?	Weighted decision matrix
Opportunity Cost	What are we giving up?	Explicit trade-offs

Minimum requirement: All 11 lenses scanned, at least 5 applied in depth.

See: references/multi-lens-framework.md

1C: Regression Questioning

Iterative self-questioning until no new insights emerge:

ROUND N:
│
├── "What am I missing?"
├── "What would an expert in {domain} add?"
├── "What would make this fail?"
├── "What will this look like in 2 years?"
├── "What's the weakest part of this design?"
└── "Which thinking model haven't I applied?"
    │
    └── New insights > 0?
        │
        ├── YES → Incorporate and loop
        └── NO → Check termination criteria

Termination Criteria:

• Three consecutive rounds produce no new insights
• All 11 thinking models have been applied
• At least 3 simulated expert perspectives considered
• Evolution/timelessness explicitly evaluated
• Automation opportunities identified

See: references/regression-questions.md

1D: Automation Analysis

Identify opportunities for scripts that enable agentic operation:

FOR EACH operation in the skill:
│
├── Is this operation repeatable?
│   └── YES → Consider generation script
│
├── Does this produce verifiable output?
│   └── YES → Consider validation script
│
├── Does this need state across sessions?
│   └── YES → Consider state management script
│
├── Does this involve external tools?
│   └── YES → Consider integration script
│
└── Can Claude verify success autonomously?
    └── NO → Add self-verification script

Automation Lens Questions:

Question	Script Category if YES
What operations will be repeated identically?	Generation
What outputs require validation?	Validation
What state needs to persist?	State Management
Can the skill run overnight autonomously?	All categories
How will Claude verify correct execution?	Verification

Decision: Script vs No Script

Create Script When	Skip Script When
Operation is deterministic	Requires human judgment
Output can be validated	One-time setup
Will be reused across invocations	Simple text output
Enables autonomous operation	No verification needed
External tool integration	Pure Claude reasoning

See: references/script-integration-framework.md

Specification Validation

Before proceeding to Phase 3:

• All sections present with no placeholders
• Every decision includes WHY
• Timelessness score ≥ 7 with justification
• At least 2 extension points documented
• All requirements traceable to source
• Scripts section complete (if applicable)
• Agentic capabilities documented (if scripts present)

Deep Dive: Phase 3 - Generation

Context: Fresh, clean (no analysis artifacts polluting) Standard: Zero errors—every section verified before proceeding

Generation Order

1. Create directory structure
   mkdir -p ~/.claude/skills/{skill-name}/references
   mkdir -p ~/.claude/skills/{skill-name}/assets/templates
   mkdir -p ~/.claude/skills/{skill-name}/scripts  # if scripts needed

2. Write SKILL.md
   • Frontmatter (YAML - allowed properties only)
   • Title and brief intro
   • Quick Start section
   • Triggers (3-5 varied phrases)
   • Quick Reference table
   • How It Works overview
   • Commands
   • Scripts section (if applicable)
   • Validation section
   • Anti-Patterns
   • Verification criteria
   • Deep Dive sections (in <details> tags)

3. Generate reference documents (if needed)
   • Deep documentation for complex topics
   • Templates for generated artifacts
   • Checklists for validation

4. Create assets (if needed)
   • Templates for skill outputs

5. Create scripts (if needed)
   • Use script-template.py as base
   • Include Result dataclass pattern
   • Add self-verification
   • Document exit codes
   • Test before finalizing

Quality Checks During Generation

Check	Requirement
Frontmatter	Only allowed properties (name, description, license, allowed-tools, metadata)
Name	Hyphen-case, ≤64 chars
Description	≤1024 chars, no angle brackets
Triggers	3-5 distinct, natural language
Phases	1-3 max, not over-engineered
Verification	Concrete, measurable
Tables over prose	Structured information in tables
No placeholder text	Every section fully written
Scripts (if present)	Shebang, docstring, argparse, exit codes, Result pattern
Script docs	Scripts section in SKILL.md with usage examples

Deep Dive: Phase 4 - Multi-Agent Synthesis

Panel: 3-4 Opus agents with distinct evaluative lenses Requirement: Unanimous approval (all agents) Fallback: Return to Phase 1 with feedback (max 5 iterations)

Panel Composition

Agent	Focus	Key Criteria	When Active
Design/Architecture	Structure, patterns, correctness	Pattern appropriate, phases logical, no circular deps	Always
Audience/Usability	Clarity, discoverability, completeness	Triggers natural, steps unambiguous, no assumed knowledge	Always
Evolution/Timelessness	Future-proofing, extension, ecosystem	Score ≥7, extension points clear, ecosystem fit	Always
Script/Automation	Agentic capability, verification, quality	Scripts follow patterns, self-verify, documented	When scripts present

Script Agent (Conditional)

The Script Agent is activated when the skill includes a scripts/ directory. Focus areas:

Criterion	Checks
Pattern Compliance	Result dataclass, argparse, exit codes
Self-Verification	Scripts can verify their own output
Error Handling	Graceful failures, actionable messages
Documentation	Usage examples in SKILL.md
Agentic Capability	Can run autonomously without human intervention

Script Agent Scoring:

Score	Meaning
8-10	Fully agentic, self-verifying, production-ready
6-7	Functional but missing some agentic capabilities
<6	Requires revision - insufficient automation quality

Agent Evaluation

Each agent produces:

## [Agent] Review

### Verdict: APPROVED / CHANGES_REQUIRED

### Scores
| Criterion | Score (1-10) | Notes |
|-----------|--------------|-------|

### Strengths
1. [Specific with evidence]

### Issues (if CHANGES_REQUIRED)
| Issue | Severity | Required Change |
|-------|----------|-----------------|

### Recommendations
1. [Even if approved]

Consensus Protocol

IF all agents APPROVED (3/3 or 4/4):
    → Finalize skill
    → Run validate-skill.py
    → Update registry
    → Complete

ELSE:
    → Collect all issues (including script issues)
    → Return to Phase 1 with issues as input
    → Re-apply targeted questioning
    → Regenerate skill and scripts
    → Re-submit to panel

IF 5 iterations without consensus:
    → Flag for human review
    → Present all agent perspectives
    → User makes final decision

See: references/synthesis-protocol.md

Deep Dive: Evolution/Timelessness

Every skill is evaluated through the evolution lens:

Temporal Projection

Timeframe	Key Question
6 months	How will usage patterns evolve?
1 year	What ecosystem changes are likely?
2 years	What new capabilities might obsolete this?
5 years	Is the core problem still relevant?

Timelessness Scoring

Score	Description	Verdict
1-3	Transient, will be obsolete in months	Reject
4-6	Moderate, depends on current tooling	Revise
7-8	Solid, principle-based, extensible	Approve
9-10	Timeless, addresses fundamental problem	Exemplary

Requirement: All skills must score ≥7.

Anti-Obsolescence Patterns

Do	Don't
Design around principles	Hardcode implementations
Document the WHY	Only document the WHAT
Include extension points	Create closed systems
Abstract volatile dependencies	Direct coupling
Version-agnostic patterns	Pin specific versions

See: references/evolution-scoring.md

Architecture Pattern Selection

Select based on task complexity:

Pattern	Use When	Structure
Single-Phase	Simple linear tasks	Steps 1-2-3
Checklist	Quality/compliance audits	☐ Item verification
Generator	Creating artifacts	Input → Transform → Output
Multi-Phase	Complex ordered workflows	Phase 1 → Phase 2 → Phase 3
Multi-Agent Parallel	Independent subtasks	Launch agents concurrently
Multi-Agent Sequential	Dependent subtasks	Agent 1 → Agent 2 → Agent 3
Orchestrator	Coordinating multiple skills	Meta-skill chains

Selection Decision Tree

Is it a simple procedure?
├── Yes → Single-Phase
└── No → Does it produce artifacts?
    ├── Yes → Generator
    └── No → Does it verify/audit?
        ├── Yes → Checklist
        └── No → Are subtasks independent?
            ├── Yes → Multi-Agent Parallel
            └── No → Multi-Agent Sequential or Multi-Phase
