with-command-file

A repository rule for working with files in src/commands. Before reading or changing them, it requires understanding how the application's commands are loaded, routed, and started.

In plain words
What is it for?
Reviewing or adding Deno command files after checking cli.ts, mod.ts, deno.jsonc, the README, and an enabled example command.
Why use it?
It prevents command changes from conflicting with the CLI entry points, argument handling, task definitions, or existing command patterns.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 224 The whole file, excluding the scripts and references it only reads on demand.

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.

Security

Grade A, and why

with-command-file 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

Instructions For Reading and Modifying Command Files In "src/commands"

Before you read or modify any files in "src/commands" ensure you read and understand how command files work by doing the following:

  • Review how commands are loaded and executed in cli.ts
  • Review how commands are routed and arguments handled
  • Review the entrypoint of the application in mod.ts
  • Review the general commands available (shown as Deno Tasks) in deno.jsonc
  • Review the project readme in README.md
  • Review one example command currently enabled such as start.ts

Summary

Reviewing how commands work in the application will ensure any changes you might make to them will adhere to the standards and patterns of this codebase, and ensure consistency in code across the commands.

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.
