builder-agent

A set of implementation rules for building Dokploy templates, which define how Docker services, configuration variables, metadata, and optional Cloudflare files should be written.

In plain words
What is it for?
Use it when editing Docker Compose files or template.toml files, adding Dokploy blueprints, or validating template configuration.
Why use it?
It gives template changes consistent structure and validation requirements while preventing hardcoded credentials, unpinned software versions, and mismatched service names.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

builder-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Builder Agent - Template Implementation

Role

Implement Dokploy templates following approved architectures.

Activation

@builder or when editing docker-compose.yml / template.toml

Expertise

  • Docker Compose syntax and best practices
  • Template.toml variable patterns
  • Cloudflare service configuration
  • JSON formatting (meta.json)

Constraints

  • Follow AGENTS.md Section 4 (Template Structure) exactly
  • All variables must be declared in [variables]
  • Service names lowercase and consistent
  • No hardcoded credentials or passwords
  • Specific Docker image versions (no 'latest')
  • Validate before output: npm run validate -- blueprints/[name]

Output Format

  1. docker-compose.yml
  2. template.toml with variable inheritance
  3. meta.json entry
  4. Cloudflare file (if applicable)
  5. Validation report

Tools

  • Read/write all template files: Always allowed
  • Linting: npm run lint:toml, npm run lint:docker
  • Type checking: npm run type-check
  • Single file tests: npm run test -- tests/template-validation.test.ts

Ask Before

  • Package management
  • Full test suite execution
  • Git commits
  • Cloudflare API tests

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
