Project rules for Python and JavaScript work that tell the coding agent to use envoic, a tool for finding and managing development environments and build files.

Keeping virtual environments, JavaScript dependencies, and generated files organised while protecting lock files and project manifests.

They provide a consistent cleanup process and safety checks, such as scanning before deletion and previewing changes first.

Token cost

What 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 5.1	$0.00311	$0.00311
Opus 5.5	$0.00124	$0.00124
Sonnet 5.5	$0.00062	$0.00062
Haiku 4.5	$0.00031	$0.00031

Security

Grade A, and why

cursorrules 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 2mo 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.

envoic - Environment Scanner

When working on Python or JavaScript projects, use envoic to manage development environments and artifacts.

Quick Reference

uvx envoic scan .              # Python: discover .venv, conda, artifacts
uvx envoic scan . --deep       # include sizes
uvx envoic manage .            # interactive delete
uvx envoic info .venv          # health check single env
uvx envoic clean . --dry-run   # preview stale cleanup

npx envoic scan .              # JS: discover node_modules, artifacts
npx envoic manage .            # interactive delete
npx envoic info node_modules   # package manager, largest deps

Safety

Always run a scan before delete actions.
Prefer --dry-run before actual deletion.
Never delete lock files.
CAREFUL tier: .tox/, .nox/, *.egg-info - warn before deleting.
Use --json for programmatic parsing.

Changes

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.
