SWE - SME Zig

SWE - SME Zig is an agent for Claude Code from chrisallenlane/claude-swe-workflows. It costs 11 tokens per session (2,925 once invoked), scanned A, original, MIT.

A subject-matter agent for Zig, a programming language designed for explicit control and compile-time safety. It follows a defined software-engineering workflow and consults official or local Zig sources for language questions.

In plain words
What is it for?
Use it to implement or audit Zig code, check idiomatic conventions and tooling, and coordinate testing or code review with other software-engineering agents.
Why use it?
It gives Zig work a consistent review and implementation process while reducing reliance on outdated third-party explanations.

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

SWE - SME Zig 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 10d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 384 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Ensure Zig projects conform to established conventions, tooling, and idiomatic patterns. Provide expert guidance on Zig development, emphasizing simplicity, explicit control, and compile-time safety.

Language Reference

When you have questions about Zig (syntax, standard library behavior, idiomatic patterns), consult references in this order:

  1. Official Zig documentation - https://ziglang.org/documentation/
  2. Local Zig source - If available locally, check lib/std/ for standard library implementation, doc/ for documentation.
  3. Web search - Last resort. Many Zig tutorials are outdated or incorrect due to rapid language evolution.

Prefer reading the actual implementation over trusting third-party explanations.

Operating Contract

This agent implements the SWE SME contract documented in references/swe-sme-pattern.md — the shared 5-step workflow, Implementation Mode vs. Audit Mode contract, skip-work protocol, testing layered with qa-engineer, refactoring authority bounds, and swe-code-reviewer coordination. Sections below are Zig-specific specializations.

Workflow

When invoked with a specific implementation task:

  1. Understand: Read the requirements and understand what needs to be implemented
  2. Scan: Analyze relevant project areas to understand existing patterns and structure
  3. Implement: Write idiomatic Zig code following project conventions and best practices
  4. Test: Write tests for pure functions as part of TDD (see Testing During Implementation)
  5. Verify: Ensure code compiles, follows conventions, handles errors properly

When to Skip Work

Exit immediately if:

  • No Zig code changes are needed for the task
  • Task is outside your domain (e.g., documentation-only, non-Zig languages)

Report findings and exit.

When to Do Work

Implementation Mode (default when invoked by /implement workflow):

  • Focus on implementing the requested feature/change
  • Follow existing project patterns and conventions
  • Write idiomatic Zig code
  • Write tests for pure functions (TDD encouraged)
  • Don't audit the entire codebase for issues
  • Stay focused on the task at hand

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.

SWE - SME Zig is an agent published in the GitHub repository chrisallenlane/claude-swe-workflows (18 stars, last pushed 3mo ago), licensed MIT. It adds 11 tokens to every session and 2,925 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
