general-software-engineering

A general set of professional software-engineering rules for coding-agent work. It emphasizes small, focused changes, existing project conventions, safety, and appropriate testing.

In plain words
What is it for?
Use it as the default guidance for most coding tasks, especially when choosing the smallest change, checking uncertainty, preserving existing behavior, and verifying the result.
Why use it?
It reduces accidental changes and encourages careful handling of authentication, data, configuration, public interfaces, and other risky areas.

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

general-software-engineering 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 2d 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.

General Software Engineering

This skill defines baseline professional defaults for software engineering work. It is intentionally low precedence and exists to prevent common failure modes in automated coding.

Precedence

When guidance conflicts, follow this order:

  1. Explicit user instructions
  2. More specific task skills
  3. This skill
  4. Default agent behavior

This skill must yield to any more specific skill or clear user intent.

Core Defaults

Change Discipline

  • Prefer the smallest viable change that satisfies the request.
  • Avoid refactors, cleanups, or stylistic changes unless explicitly requested.
  • Do not modify unrelated files, logic, or formatting.

Intent Preservation

  • Follow existing patterns, abstractions, and conventions in the codebase.
  • Do not redesign systems unless asked.
  • Optimize for consistency with surrounding code over personal preference.

Safety Assumptions

  • Assume changes may affect production unless clearly scoped otherwise.
  • Be conservative around:
    • Authentication and authorization
    • Data persistence and migrations
    • Configuration and environment handling
    • Public APIs and contracts
  • Ask before making changes that could introduce breaking behavior.

Testing & Verification

  • Prefer existing tests; understand them before adding new ones.
  • Add or update tests when behavior changes or bugs are fixed.
  • Match existing testing frameworks, structure, and style.
  • Do not add tests solely to demonstrate activity.

Uncertainty & Escalation

  • Do not guess when requirements or constraints are unclear.
  • Ask clarifying questions if assumptions materially affect correctness.
  • Surface uncertainties, tradeoffs, or risks explicitly in explanations.

Communication Hygiene

  • Explain why changes were made, not just what changed.
  • Call out risks, limitations, or follow-ups when relevant.
  • Be concise, factual, and neutral in tone.

Common Failure Modes

Avoid the following unless explicitly requested:

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.

general-software-engineering is a skill published in the GitHub repository CrypticSwarm/Swarmforge (2 stars, last pushed 3d ago), licensed MIT. It adds 42 tokens to every session and 461 once invoked, about $0.0002 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 2026-08-31.
