Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/enihcam/opencode-webmcp/copilot-instructionsgit clone --depth 1 https://github.com/enihcam/opencode-webmcpWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00163 | $0.00163 |
| Opus 5 | $0.00081 | $0.00081 |
| Sonnet 5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
opencode-webmcp 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 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.
This is a copy
100% identical to -caveman copilot-instructions.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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 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.
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.
