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.

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 | $0.00300 | $0.00300 |
| Opus 5 | $0.00150 | $0.00150 |
| Sonnet 5 | $0.00060 | $0.00060 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
dc 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
GitHub Copilot — Project Instructions
This repo ships dc-py — a single-file Python client at
py/dc.py that wraps the public DC Member API.
When suggesting code in this repo:
- Stay stdlib-only — no
requests, nohttpx, nopydantic. The skill is intentionally zero-dependency. - The skill file is the canonical entry point. Do not split it into multiple modules.
- Two-class pattern:
DCis the public wrapper,_DCCoreis the private helper with all HTTP and parsing logic. Keep new commands in this same shape. - Register CLI commands with
@skill_command(name=, help=, parser=). Don't introduce new decorators or modes. - Space-form CLI flags (
--limit 10, not--limit=10). - All list-returning commands return the envelope
{items, count, cursor, has_more}— use the_wrap_listhelper. - API base URL:
https://api.dynamitecircle.com. Auth header:Authorization: Bearer dk_<api-key>. - Env config lives in
py/.env.dc(skill-local).
For the user-facing setup instructions, see ../CLAUDE.md and ../py/SKILL.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.

dc copilot-instructions.md is an instructions file published in the GitHub repository dynamitecircle/dc (5 stars, last pushed 27d ago), licensed MIT. It adds 300 tokens to every session, about $0.0015 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.
