SkillSignal prompt templates

Provide the task, context, and acceptance criteria

These prompts were written by SkillSignal from the source structure; they are not upstream text.

Task-start prompt

Confirm source fit, inputs, and outputs before acting.

Use safety-guard to help me with: [specific task]. Context: [files, data, or background]. Constraints: [environment, scope, and prohibited actions]. Before acting, check the pinned SKILL.md and explain which sections apply, what inputs are still missing, and what you will deliver.

Source-guided execution

Make the Agent explicitly follow the key extracted sections.

Apply the pinned safety-guard source to [task]. Pay particular attention to these source sections: “Implementation”, “When to Use”, “How It Works”, “Mode 1: Careful Mode”, “Mode 2: Freeze Mode”. Preserve the important decision at each step. Mark facts not covered by the source as “needs confirmation” instead of inventing them. Then verify the result against my acceptance criteria: [criteria].

Result-review prompt

Check omissions, permissions, and source drift before delivery.

Review the current safety-guard result: (1) does it satisfy the original task; (2) were any applicable steps or limits in the pinned SKILL.md missed; (3) did it perform any unauthorized file, command, network, or data action; and (4) which conclusions remain unverified? List issues first, then fix only what the source or user authorization supports.

Output checklist

dask by k-dense-ai

Distributed computing for larger-than-RAM pandas/NumPy workflows. Use when you need to scale existing pandas/NumPy code beyond memory or across clusters. Best for parallel file processing, distributed ML, integration with existing pandas code. For out-of-core analytics on single machine use vaex; for in-memory speed use polars.

medchem by k-dense-ai

Medicinal chemistry filters for compound triage. Apply drug-likeness rules (Lipinski, Veber, CNS), structural alert catalogs (PAINS, NIBR, ChEMBL), complexity metrics, and the medchem query language for library filtering.

Safety Guard — Prevent Destructive Operations

When to Use

When working on production systems
When agents are running autonomously (full-auto mode)
When you want to restrict edits to a specific directory
During sensitive operations (migrations, deploys, data changes)

How It Works

Three modes of protection:

Mode 1: Careful Mode

Intercepts destructive commands before execution and warns:

Watched patterns:
- rm -rf (especially /, ~, or project root)
- git push --force
- git reset --hard
- git checkout . (discard all changes)
- DROP TABLE / DROP DATABASE
- docker system prune
- kubectl delete
- chmod 777
- sudo rm
- npm publish (accidental publishes)
- Any command with --no-verify

When detected: shows what the command does, asks for confirmation, suggests safer alternative.

Mode 2: Freeze Mode

Locks file edits to a specific directory tree:

/safety-guard freeze src/components/

Any Write/Edit outside src/components/ is blocked with an explanation. Useful when you want an agent to focus on one area without touching unrelated code.

Mode 3: Guard Mode (Careful + Freeze combined)

Both protections active. Maximum safety for autonomous agents.

/safety-guard guard --dir src/api/ --allow-read-all

Agents can read anything but only write to src/api/. Destructive commands are blocked everywhere.
