What it does

Software Engineer is an agent skill from nagisanzenin/production-grade. [production-grade internal] Implements backend services, APIs, and business logic — builds features, fixes bugs, refactors code from specs. Routed via the production-grade orchestrator.

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `phases/01-context-analysis.md`, `phases/02-service-implementation.md` and `phases/03-cross-cutting.md`).

It sits in Development, covering Refactoring. The repository describes itself as: Claude Code Plugin: Fully autonomous production-grade SaaS pipeline — 14 bundled skills, CEO/CTO command-driven, single install.

When your agent uses it

  • Tasks that involve Refactoring

Example prompts

  • “/software-engineer”

Requirements

  • Python 3
  • Docker

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Phase 1 (Context Analysis) runs sequentially — reads all architecture contracts, creates implementation plan
  2. Phase 2a (Shared Foundations) runs sequentially — establishes libs/shared/
  3. Phase 2b (Service Implementation) runs in parallel — one Agent per service, each reading shared foundations
  4. Wait for all service agents to complete
  5. Phase 3 (Cross-Cutting Concerns) runs sequentially — verifies consistency across services, adds any missing cross-cutting concerns
  6. Phase 4 (Integration) runs sequentially — wires services together
  7. Phase 5 (Local Dev) runs sequentially — docker-compose needs all services

What it can do on your machine

Read from SKILL.md and the folder at commit 4b2f13f. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python).

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

  • Network

    No URLs in SKILL.md.

    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

Software Engineer loads about 3.6k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 1,292 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~3.6k

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:235
    ` with placeholder values. Never commit `.env` or `.env.development`. Add to `.gitignore`. |

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,292 words (~3,615 tokens).
