At a glance

A skill your agent uses when adding, extending, modifying, or removing berdctl commands, verbs, nouns, schemas, help text, or any of the berdctl surface.

  • Calls pnpm, just and cargo
  • Any of the berdctl surface

What it does

Berdctl New Command is an agent skill from block/berd, published by the product's own GitHub organization. Use when adding, extending, modifying, or removing berdctl commands, verbs, nouns, schemas, help text, or any of the berdctl surface.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Tauri. The repository describes itself as: a desktop app for getting work done with any model. The licence is Apache-2.0.

When your agent uses it

  • Removing berdctl commands
  • Any of the berdctl surface

Example prompts

  • “/berdctl-new-command”

What it can do on your machine

Read from SKILL.md and the folder at commit 5bcf29b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pnpm
    • just
    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Berdctl New Command loads about 574 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 266 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~574

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

berdctl command changes

One command is one renderer module. Descriptors are the source for zod validation, TS input types, CLI help, and generated contract JSON. Background: docs/berdctl-architecture.md.

Rules

  • Verbs must be UI-visible. Prefer reversible mutations, but one-way visible product actions like creating a session or sending a prompt are allowed. Delete, bulk, silent, invisible, or broadly destructive work requires auth/confirmation design review.
  • Put bounds in zod; clap mirrors them.
  • Keep descriptors import-pure. Import stores, Tauri APIs, navigation, providers, and caches only inside execute/precheck.
  • Do not hand-edit generated contract JSON.
  • Keep the broker command-agnostic; normal command changes do not touch src-tauri/plugins/berdctl/.
  • Breaking wire reshapes bump both discovery.rs constants and the contract mirror. New commands and optional fields are not reshapes.

Workflow

  • Add commands with just new-command <noun> <verb>.
  • Implement src/features/berdctl/commands/impl/<verbNoun>.ts with: .strict() schema, .describe() on every field, summary, description, helpFooter, safety metadata, optional precheck, and execute.
  • Update inventories only when needed: registry.ts group cli.about, top-level help pins in tree.rs, and distro/skills/berdctl/SKILL.md for overview changes.
  • Run pnpm generate:berdctl-contract, pnpm vitest run src/features/berdctl, and cargo test -p berdctl from src-tauri/.
  • Before review, confirm the verb is UI-visible and either reversible or a direct visible product action, help is complete, error messages name the fixing command, artifacts are regenerated, and tests cover the behavior.

Keep CLI shapes expressible by the generated field walker. If a requested operation needs an explicit null or another shape that generic flags cannot represent safely, model it as a separate command action instead of adding command-specific Rust mapping. Example: use session move --project-id <id> for moving into a project and session clear-project for moving out.
