write-engineering-guidance

write-engineering-guidance is a command for Claude Code from YourTechBud/coding-harness-config. It costs 11 tokens per session (454 once invoked), scanned A, original, Apache-2.0.

A command for turning decisions from the current conversation into engineering guidance documents, such as principles, usage instructions, and focused guidance on architecture or runtime behavior.

In plain words
What is it for?
It helps create or refactor guidance files when the conversation has already settled the key principles and document structure.
Why use it?
Engineering decisions are easy to lose when they remain only in chat. Writing them down gives the project a reusable reference for future work.

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

write-engineering-guidance 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 2mo 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.

What it actually says

Use the current conversation as the source of truth.

If the conversation has not yet converged on the guidance shape and key principles, stop and ask the user to continue with /brainstorm-engineering-guidance first.

<default_shape> Unless the conversation already settled on a better structure, start from:

  • docs/engineering-guidance/README.md
  • docs/engineering-guidance/core-principles.md
  • docs/engineering-guidance/how-to-use.md

And a small docs/engineering-guidance/lenses/ set, likely including:

  • architecture, modules, and boundaries
  • state, effects, and runtime behavior

You may add, merge, split, rename, or remove lens docs if that produces a better fit for the repo and the conversation.

If the brainstorm conversation produced severity calibration (Blocker / Concern / Nit) or rules for consuming the reviewer's Architectural Reflection channel, mention them briefly in how-to-use.md or inline where it's load-bearing. Do not invent calibration or consumption rules the conversation did not produce. </default_shape>

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.
