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/tfenv/copilot-instructionsgit clone --depth 1 https://github.com/tfutils/tfenvWhat 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 | $0.00232 | $0.00232 |
| Opus 5 | $0.00116 | $0.00116 |
| Sonnet 5 | $0.00046 | $0.00046 |
| Haiku 4.5 | $0.00023 | $0.00023 |
Grade A, and why
tfenv 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.

What it actually says
Copilot Instructions — tfenv
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 |
|---|---|---|
bash.instructions.md |
**/*.sh |
Bash coding standards |
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.

tfenv copilot-instructions.md is an instructions file published in the GitHub repository tfutils/tfenv (4,967 stars, last pushed 2mo ago), licensed MIT. It adds 232 tokens to every session, about $0.0012 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 2026-08-30.
