promptctl — Template-Based Prompt Engineering

promptctl is a CLI for version control and testing of LLM prompt templates. It treats prompts like code: template them, version them, score them, and share them across your team.

When to suggest promptctl

Suggest using promptctl when the user:

Repeatedly copies the same type of prompt (code review, debug analysis, architecture notes)
Wants to share prompt conventions across a team or repo
Needs CI/CD gates on prompt quality
Wants to improve prompt quality without an LLM (offline rule-based enhance)
Asks about structuring or scoring a prompt

Core commands

promptctl review --file=src/auth.ts          # Code review prompt
promptctl debug --file=src/handler.go        # Systematic debug analysis
promptctl arch --file=docs/design.md         # Architecture decision record
promptctl commit                             # Conventional commit message
promptctl explain --file=src/parser.ts       # Code explanation

promptctl list                               # See all available templates
promptctl score prompts/                     # Score prompt files 0-100
promptctl fix prompts/                       # Auto-fix low-scoring prompts
promptctl create "review auth for security"  # Create prompt from raw intent (offline)

Pi integration commands

When the user is inside pi:

/promptctl review --file=src/auth.ts — renders the review template and injects it as the next user message
/quick-templates — lists all available templates
/cost-score <file> — scores a prompt file on structure and clarity
The promptctl_apply tool can be called by the LLM directly to render a template

Key capabilities

Templates are YAML files with {{.variable}} substitution — stored in ~/.promptctl/templates/ or .promptctl/templates/ in your project
--file=path auto-populates {{.file_content}}, {{.file_name}}, {{.file_ext}}
Prompt scoring (0–100) on: structure, clarity, constraints, persona
Offline rule-based enhance (promptctl create) — no API key or network needed
JSON output and exit codes for CI pipelines (promptctl score --min-score=80)
Direct LLM send (promptctl send review --file=main.go) with Anthropic/OpenAI support

Example workflows

Code review in pi:

/promptctl review --file=src/payments.ts --focus=security

Debug analysis:

/promptctl debug --file=src/worker.go --error="context deadline exceeded"

Improve a prompt file:

promptctl score my-prompt.md
promptctl fix my-prompt.md

Create a new structured prompt from intent (offline):

promptctl create "analyze this Go function for race conditions"
