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/dgenio/chainweaver/copilot-instructionsgit clone --depth 1 https://github.com/dgenio/ChainWeaverWhat 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 | $0.00653 | $0.00653 |
| Opus 5 | $0.00327 | $0.00327 |
| Sonnet 5 | $0.00131 | $0.00131 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
ChainWeaver 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.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot Instructions — ChainWeaver
Thin review-oriented layer. Canonical source of truth: AGENTS.md, the path-scoped
AGENTS.mdfiles it indexes, and docs/agent-context/.
Scoped guidance
Path-scoped AGENTS.md files carry durable subsystem rules (nearest file
applies; the root file always applies and cannot be weakened). The canonical
index is AGENTS.md § 11
— for a change spanning several subsystems, apply every scoped file whose
subtree is touched. The detailed module inventory is
module-map.md.
Review-critical rules
- Review code and agent-facing docs together. If a PR changes behavior, invariants, architecture, or workflows, the corresponding docs must be updated in the same PR.
- Invariants take priority over cleanup, simplification, or local refactors. See AGENTS.md § Core invariants.
- Do not invent conventions. All coding style, naming, workflow, and testing rules are grounded in AGENTS.md and docs/agent-context/. If guidance is missing, surface the gap — do not guess.
- Use authoritative commands exactly as written in AGENTS.md § Validation commands. Do not substitute alternative flags, paths, or invocations.
- If you find a contradiction or stale content in any doc, flag it explicitly. Do not silently work around it.
Executor guardrails
executor.py has three hard invariants — no LLM calls, no network I/O, no
randomness. These are non-negotiable. See
invariants.md.

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.

ChainWeaver copilot-instructions.md is an instructions file published in the GitHub repository dgenio/ChainWeaver (6 stars, last pushed 3d ago), licensed Apache-2.0. It adds 653 tokens to every session, about $0.0033 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.
