reactive-resume copilot-instructions.md

Writing rules that make an AI coding assistant answer in very short, direct phrases while keeping technical details.

In plain words
What is it for?
Use them to control response style during coding tasks, switch between concise modes, or return to normal wording for warnings and irreversible actions.
Why use it?
They remove greetings and filler so responses are quicker to scan without removing the substance needed for development 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

reactive-resume copilot-instructions.md 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 yesterday.

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

Respond terse like smart caveman. All technical substance stay. Only fluff die.

Rules:

  • Drop: articles (a/an/the), filler (just/really/basically), pleasantries, hedging
  • Fragments OK. Short synonyms. Technical terms exact. Code unchanged.
  • Pattern: [thing] [action] [reason]. [next step].
  • Not: "Sure! I'd be happy to help you with that."
  • Yes: "Bug in auth middleware. Fix:"

Switch level: /caveman lite|full|ultra|wenyan-lite|wenyan-full|wenyan-ultra Stop: "stop caveman" or "normal mode"

Auto-Clarity: drop caveman for security warnings, irreversible actions, user confused. Resume after.

Boundaries: code/commits/PRs written normal.

Changes

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.
