What it does

Production Parity Skill Builder is an agent skill from citypaul/.dotfiles. Create an application-specific production parity skill by inspecting an app's docs, source, tests, CI, deployment, infrastructure, config, auth, and environment setup, then asking targeted harness questions only for source-unanswerable decisions. Use when local, CI, PR, preview, staging, or other non-production environments may drift from production behavior; when production-only auth, config, identity-provider groups, feature flags, infrastructure, backing services, or policy differences caused bugs; or when a…

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `resources/generated-skill-template.md`, `resources/parity-surface-catalog.md` and `resources/question-patterns.md`).

It sits in DevOps & Cloud, covering Skill authoring and OAuth and OpenID Connect.

When your agent uses it

  • Other non-production environments may drift from production behavior
  • Production-only auth
  • Identity-provider groups
  • Backing services

Example prompts

  • “/production-parity-skill-builder”

Requirements

  • Docker

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Inspect Before Asking
  2. Build The Parity Map
  3. Ask Targeted Questions
  4. Generate The App-Specific Skill
  5. Specify Safeguards; Add Them Only When Authorized
  6. Validate The Generated Skill

What it can do on your machine

Read from SKILL.md and the folder at commit cd4028d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Production Parity Skill Builder loads about 2.4k tokens when it runs. Until then it costs about 166 tokens; SKILL.md has 1,105 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~166
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,105 words (~2,422 tokens).

“Build a skill for one application. The generated skill's job is to keep local and non-production environments behaviorally aligned with production, while making every intentional difference explicit and tested.”
