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 | $0.00195 | $0.00195 |
| Opus 5 | $0.00097 | $0.00097 |
| Sonnet 5 | $0.00039 | $0.00039 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
threadbase 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
Threadbase Instructions for GitHub Copilot
- Read
.ai/generated/index.mdbefore making important changes. - If
.ai/generated/index.mdis missing or empty, generate it from scratch using.ai/prompts/generate_index.mdbefore meaningful implementation work. - Read
.ai/generated/context.mdwhen the task needs broader project state, active constraints, or recent cross-cutting changes. - If
.ai/generated/context.mdis missing or empty, generate it from scratch using.ai/prompts/generate_context.mdbefore meaningful implementation work. - Keep generated files compact and only open relevant files under
.ai/memory/*when deeper detail is needed. - Use
.ai/memory/*as the source of truth for decisions, changes, requirements, and issues. - Update project memory after meaningful work.
- Regenerate index/context from memory when either file is missing, empty, or stale.
- Do not store secrets in Threadbase files.
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.

threadbase copilot-instructions.md is an instructions file published in the GitHub repository ani3198/threadbase (4 stars, last pushed 2mo ago), licensed MIT. It adds 195 tokens to every session, about $0.0010 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.
