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/tfutils/tfscaffold/copilot-instructionsgit clone --depth 1 https://github.com/tfutils/tfscaffoldWhat 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 | $0.00233 | $0.00233 |
| Opus 5 | $0.00117 | $0.00117 |
| Sonnet 5 | $0.00047 | $0.00047 |
| Haiku 4.5 | $0.00023 | $0.00023 |
Grade A, and why
tfscaffold 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
91% identical to tfenv copilot-instructions.md — 2 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
Copilot Instructions — tfscaffold
This file is intentionally minimal. The canonical source for project
architecture, conventions, and agent guidelines is AGENTS.md
at the repository root.
Auto-Loaded Instructions
Language-specific coding standards are in .github/instructions/ and use
applyTo frontmatter to load automatically when editing matching files:
| File | Applies To | Purpose |

Agent Definitions
Agent definitions live in .github/agents/ as .agent.md files. Each agent
has a YAML frontmatter block with description, tools, model, and
argument-hint fields.

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.
