SkillFit Optimizer

Skill type

Agent configuration / Skill selection / Workflow optimization

Safety profile

Low risk. Runs in analysis mode by default and only modifies the environment when explicitly requested.

Purpose

SkillFit Optimizer helps determine the smallest reliable skill stack needed to accomplish a user's goal.

Instead of installing many tools blindly, the optimizer:

• analyzes the goal
• maps required capabilities
• identifies candidate skills
• removes redundant tools
• checks environment readiness
• scores candidate stacks
• recommends the most reliable configuration

This helps prevent:

• tool sprawl
• overlapping capabilities
• fragile workflows
• unnecessary dependencies

Quick Start

Example request:

"What is the best skill stack for editing PDFs and analyzing documents?"

The optimizer will:

1. analyze the goal
2. identify required capabilities
3. build candidate skill stacks
4. check environment readiness
5. recommend the best stack

Triggers

Invoke this skill when users ask:

• "What skills do I need for this task?"
• "Optimize my skill stack."
• "Recommend a minimal tool setup."
• "Which skills overlap?"
• "What tools should I install?"
• "Simplify my workflow tools."

Required Inputs

• user_goal
• environment_info (optional)
• preferred_profile (optional)

Capability Mapping

User goals are translated into capability categories.

Example:

Goal: "Edit PDFs and summarize documents"

Capabilities:

• pdf_editing
• document_analysis
• summarization

Capability Matrix

Example capabilities and typical skill matches.

Capability Example Skills

pdf_editing nano-pdf document_analysis data-analysis document_editing word-docx spreadsheet_processing excel-xlsx automation skill-creator api_interaction trello

Profiles

Minimal

Smallest possible working stack.

Focus:

• lowest setup complexity
• minimal dependencies
• fastest deployment

Balanced

Balanced tradeoff between capability coverage and reliability.

Recommended default profile.

Maximum

Largest stack providing maximum redundancy and capability coverage.

Runtime Steps

1. Analyze Goal

Extract required capabilities from the request.

2. Build Capability Map

Translate the goal into structured capability categories.

3. Discover Candidate Skills

Identify available skills capable of providing each capability.

Construct:

• candidate skill list
• capability coverage map

4. Detect Overlap

Identify redundant tools performing the same capability.

Prefer fewer high-signal skills.

5. Generate Candidate Stacks

Produce stacks for each profile:

• Minimal
• Balanced
• Maximum

Each stack includes:

• skills
• capabilities covered
• missing capabilities (if any)

6. Run Environment Checks

Verify environment readiness.

Check for availability of common binaries:

python node jq curl git

Record results as:

• available
• missing
• unknown

7. Compute Stack Score

Stacks are scored across four dimensions.

Coverage --- capability satisfaction
Reliability --- stability of tools
Setup Friction --- installation complexity
Overlap Discipline --- redundancy penalty

Score formula:

score = coverage * 0.40 + reliability * 0.30 + setup_friction * 0.20 + overlap_discipline * 0.10

Score range: 0--100

8. Select Recommended Stack

Choose the highest scoring stack.

Tie‑break rules:

1. fewer skills
2. higher coverage
3. lower setup friction

9. Produce Recommendations

Return:

• recommended stack
• alternative stacks
• missing dependencies
• setup guidance

Output Contract

Return structured output:

{ "goal": "Edit PDFs and summarize documents", "recommended_profile": "balanced", "recommended_stack": [ "nano-pdf", "data-analysis" ], "stack_score": 88, "capability_coverage": [ "pdf_editing", "document_analysis", "summarization" ], "environment_check": { "python": "available", "jq": "available", "curl": "missing" }, "alternatives": { "minimal": ["nano-pdf"], "maximum": ["nano-pdf", "data-analysis", "skill-creator"] } }

Best Practices

Prefer smaller stacks when possible.

Avoid overlapping tools that provide identical functionality.

Check environment readiness before installing skills.

Re-run the optimizer when workflows evolve.

Common Optimization Issues

Skill Bloat

Too many tools installed for simple tasks.

Solution: prune redundant skills.

Capability Gaps

Required capability missing.

Solution: add a targeted skill.

Environment Mismatch

Required binaries unavailable.

Solution: install dependencies.

Related Skills

Agent Regression Check

Use Agent Regression Check after stack changes to verify that configuration updates did not introduce regressions.

Limitations

SkillFit Optimizer:

• does not execute workflows
• cannot guarantee correctness of external tools
• provides structured recommendations rather than guarantees

Implementation Note

If a helper script such as scripts/stack_check.py exists, use it for environment checks. Otherwise perform lightweight PATH checks.
