Skill Template Writer

Note:

• Local files are not directly accessible by the server. Please upload them to the server using molclaw-file-transfer before execution.
• For PDB file inputs, it is recommended to preprocess them using molclaw-pdbfixer before execution.
• Please refer to skill molclaw-scp-server to complete tool invocation.

When to Use

Use this skill when executing Phase 3 (Skill Document Assembly) of the Skill Crystallization Meta-Workflow (L2-12). This skill provides the exact formatting templates, field specifications, and validation checklists to ensure auto-generated skill documents conform to MolClaw standards.

When NOT to Use

• Do NOT use this skill to modify existing expert-curated skills — those require human expert review.
• Do NOT use this skill outside the crystallization workflow — it has no standalone function.
• Do NOT use this skill to generate L3 principles — L3 content requires expert validation and is never auto-generated.

Prerequisites

Input	Source	Required?
Abstracted tool call sequence	L2-12 Phase 2.1	Yes
Formalized decision logic	L2-12 Phase 2.2	Yes
Invariant/variable classification	L2-12 Phase 2.3	Yes
Failure-recovery pairs	L2-12 Phase 1.3	Yes
Quality gate results	L2-12 Phase 1.4	Yes
Target level (L1 or L2)	L2-12 Phase 0.2	Yes
Trigger ID and source task summary	L2-12 Phase 0.1	Yes

Step 1: Select Template

Based on the target level and (for L2) the workflow paradigm identified in L2-12 Phase 0.4, select the appropriate template:

Target Level	Paradigm (from Phase 0.4)	Template	Reference Skeleton
L1	—	Section A: L1 Skill Template	Any existing L1 SKILL.md
L1 (T5 failure memo)	—	Section A-F: Failure Pattern Memo	Existing L1 failure-recovery tables
L2	Pipeline (A)	Section B-A: L2 Pipeline Template	L2-01, L2-07, L2-08
L2	Iterative Loop (B)	Section B-B: L2 Iterative Loop Template	L2-05, L2-10
L2	Branching Decision (C)	Section B-C: L2 Branching Decision Template	L2-02, L2-04
L2	Mixed	Choose dominant paradigm template; embed secondary paradigm within one phase	Combine reference skeletons

Key differences between L2 sub-templates:

• Pipeline (A): Phases are sequential and non-repeating. Each phase has exactly one CHECKPOINT. No seed update logic, no convergence criteria, no iteration records. The output of the final phase is the deliverable.
• Iterative Loop (B): Must include: Evaluate→Diagnose→Design→Verify cycle structure; seed molecule/state update rule between rounds; global target tracker (if cumulative termination conditions exist); convergence criteria section (L3 Principle 7); iteration record requirements referencing L3 Principle 8; docking/evaluation parameter locking if applicable.
• Branching Decision (C): Must include: scene/mode classification table at the entry point; "Use when" conditions for each branch; shared prerequisites and branch-specific prerequisites; branch-specific sub-protocols that may have different tool compositions.

When writing the skill document in Step 3, copy the structural patterns (section ordering, checkpoint placement, table formats) from the identified reference L2 workflow. This ensures the auto-generated skill is structurally familiar to the agent when it is loaded in future sessions.

Step 2: Populate YAML Header

Fill in all YAML metadata fields using the following specifications:

YAML Field Reference

Field	Format	Source	Example
name	kebab-case, prefix with context	Descriptive of function	molclaw-cryptic-pocket-ensemble-screening
description	One paragraph, max 3 sentences	Summarize the skill's purpose	"Discover transient binding pockets from..."
license	Fixed	Always	MIT license
metadata.skill-author	Fixed	Always	MolClaw-Auto
metadata.skill-level	Enum	Phase 0.2 decision	L1-Tool-AUTO or L2-Workflow-AUTO
metadata.auto-generated	Boolean	Always	true
metadata.source-task	One sentence	Source task description	"QED optimization of triazolo-benzodiazepine"
metadata.source-execution-date	ISO date	Execution date	2026-04-01
metadata.source-platform	String	Platform used	Claude Code or OpenClaw
metadata.crystallization-trigger	Enum	Phase 0.1	T1, T2, T3, T4, or T5
metadata.confidence	Enum	Always initial	LOW (first generation)
metadata.validation-record	List	Source task ID	["task-001"]
metadata.methodology-ref	Multi-line	L3 principles used	See existing L2 skills for format

Naming Convention for name field:

• Start with molclaw- prefix
• Use descriptive terms reflecting the skill's function
• Keep under 60 characters
• Examples: molclaw-reinvent-low-tanimoto-fallback, molclaw-cryptic-pocket-discovery, molclaw-multi-target-selectivity-optimization

Step 3: Populate Body Sections

Fill in each section of the selected template using the crystallization inputs. Follow the section-by-section instructions below.

3.1 Applicability Section (L2 only)

"Use when" rules:

• Generalize from the source task's characteristics to the task CLASS
• CORRECT: "Use when the user needs to identify transient binding pockets not visible in the crystal structure"
• INCORRECT: "Use when working with EGFR kinase domain PDB 1M17" (too specific)

"Do NOT use when" rules:

• List situations where this workflow is inappropriate or where an existing workflow should be used instead
• Reference existing L2 workflows by number: "Use Skill 2 instead when..."

3.2 Prerequisites Table

• List all required inputs
• For each input, specify: the source (user-provided, or output of another skill), whether it is required or optional
• Use placeholder format for task-specific inputs: $TARGET_PROTEIN, $SEED_MOLECULE, etc.

3.3 Procedure / Phase Protocol

For L1 skills: Write as numbered steps with clear tool invocations.

Each step must include:

• The SCP tool name (snake_case) — NEVER use skill names (kebab-case) in tool call contexts
• Required parameters with defaults from the source execution
• The expected output and how to verify it
• A quality check condition (derived from Phase 1.4 quality gates)

For L2 workflows: Organize into numbered phases with embedded checkpoints.

Each phase must include:

• A clear objective statement
• Specific tool calls with call_tool("tool_name", ...) syntax
• A CHECKPOINT block after each phase with pass/fail conditions
• COUNT GATE blocks where molecule/structure counts change
• MAPPING GATE blocks before residue-specific analysis (if applicable)
• Decision points formatted as conditional blocks (from Phase 2.2)

3.4 Parameters Table (recommended for all skills)

## Parameters

| Parameter | Placeholder | Default | Valid Range | Notes |
|-----------|------------|---------|-------------|-------|
| [name] | $PLACEHOLDER | [value from source] | [range] | [when to change] |

3.5 Failure-Recovery Table

Populate from Phase 1.3 extraction, generalized:

## Common Failures & Recovery

| Failure | Likely Cause | Recovery |
|---------|-------------|----------|
| [generalized failure signature] | [root cause] | [recovery steps with tool names] |

Rules for generalization:

• Replace specific error messages with patterns: "JSON parse error" → "Output parsing failure"
• Replace specific tool versions with generic references
• Ensure recovery actions reference available tools, not task-specific workarounds

3.6 Quality Gates (L2 only)

## Quality Gates (Active Checkpoints)

**CHECKPOINT after Phase N:**
- [ ] [condition from source execution, generalized]

3.7 Output Specification (L2 only)

## Output Specification (Data Handoff Contract)

| Output | Format | Consumed by | Download Policy |
|--------|--------|-------------|-----------------|
| [output name] | [format] | [downstream skill or report] | [A/B/C] |

3.8 Known Limitations

Mandatory content:

• Conditions under which the skill is expected to fail
• Aspects of the source task that were NOT generalized (and why)
• Tool version dependencies
• Grade B gaps (if the source task was Grade B per Principle 23)
• Computational cost estimate

3.9 Provenance Section

## Provenance

- **Source execution:** [task summary], [date], [platform]
- **Crystallization trigger:** [T1/T2/T3/T4] — [description]
- **Trace phases crystallized:** [list of NOVEL phases]
- **L3 principles referenced:** [list with numbers]
- **Original execution success metric:** [metric name] = [achieved value]

Step 4: Validate the Generated Document

Run through the validation checklist from L2-12 Phase 4:

Structural checks:

• YAML parses correctly
• All required sections present for the target level
• All SCP tool names are snake_case
• No kebab-case skill names in tool invocation contexts
• All placeholders have documented defaults
• No API keys, tokens, or credentials are embedded; reference environment variable names defined in .env.template

Logical checks:

• Phase dependencies are correctly ordered
• Data flow is connected
• Decision conditions are non-contradictory
• No infinite loops possible

Style consistency checks:

• Markdown heading hierarchy matches existing skills (# for title, ## for sections, ### for subsections)
• Table formatting is consistent
• Code blocks use correct syntax highlighting
• Cross-references use principle numbers (e.g., "Principle 11") not section names

Step 5: Output the Document

Write the validated document to the appropriate path:

• L1: auto-generated-skills/L1_tools/[skill-name]/SKILL.md
• L2: auto-generated-skills/L2_workflows/[skill-name].md

Verify the file was written successfully and is non-empty.

# Failure Pattern Memo: [Tool Name] — [Short Failure Description]

## Affected Tool
- SCP tool name: `[snake_case_tool_name]`
- Related L1 skill: [existing skill name, e.g., molclaw-quickvina-docking]

## Failure Condition
[Precise description of the input characteristics that trigger the failure. Must be specific enough to serve as a "Do NOT use when" condition.]

| Condition Parameter | Trigger Value / Range | How to Check |
|--------------------|----------------------|-------------|
| [e.g., seed Tanimoto to training dist.] | [e.g., < 0.3] | [e.g., compute Morgan FP Tanimoto against ChEMBL drug-like set] |

## Failure Signature
[What the failure looks like: error message, empty output, nonsensical values, crash, etc.]

[Exact error message or output pattern, if available]

## Root Cause Analysis
[Why the tool fails under these conditions. Agent's diagnosis based on execution evidence.]

## Recommended Avoidance Strategy
[How to avoid triggering this failure. Options:]
1. **Pre-check:** [Condition to check before calling the tool]
2. **Alternative tool:** [If available, which tool to use instead]
3. **Parameter adjustment:** [If the failure can be avoided by changing parameters]
4. **Workflow modification:** [If the workflow should route around this tool under these conditions]

## Evidence from Source Execution
- Task: [summary]
- Failure occurred at: [which phase/step]
- Number of occurrences: [how many times in the session]
- Recovery used in source task: [what the agent did to work around it]
- Outcome of recovery: [success/partial/fail]

## Integration Recommendation
This memo should be integrated into the failure-and-recovery table of skill `[target-skill-name]` as a new entry:

| Failure | Likely Cause | Recovery |
|---------|-------------|----------|
| [generalized failure signature] | [root cause] | [recommended avoidance/recovery] |

## Baseline Establishment (Phase 0)
[Establish baseline metrics before entering the loop]
[Lock parameters that must remain constant across rounds — ref L2-05 Docking Parameter Locking]

## Iterative Loop Architecture (Phases 1–N)

Each round consists of four steps forming an **Evaluate → Diagnose → Design → Verify** closed loop.

### Step 1: Current State Assessment
[Full evaluation using all relevant tools]
[Record all metrics from tool returns — Principle 11]
**CHECKPOINT after Step 1:**
- [ ] All scores from tool returns (not memory)
- [ ] Structure files downloaded

### Step 2: Diagnosis and Strategy Formulation
[Three questions from Principle 5:]
1. What is this round trying to improve? [must cite Step 1 data]
2. What strategy? [chemical/structural rationale]
3. How to measure improvement? [quantifiable criterion]

### Step 3: Design and Generation
[LLM-guided design and/or REINVENT generation]
[Scaffold preservation check if required]
[Drug-likeness filtering]
**COUNT GATE:** Verify candidate count

### Step 4: Verification and Decision
[Re-evaluate candidates with Step 1 tools]
[Compare against baseline AND previous round best]
**Decision logic:**
- IF success criteria met → Report. Done.
- ELIF round < max_rounds → Update seed (Seed Update Rule), return to Step 1
- ELSE → Report global best with complete trajectory

### Seed Update Rule
[Define how the seed molecule/state is updated between rounds]

### Global Target Tracker (if cumulative termination)
[Maintain and check cumulative progress — ref L2-05]
