At a glance

Use liberally when you create, discover, or modify a software component.

  • Agent Workflows work in your project
  • SKILL.md covers Before Adding, Command Syntax, Bad Example and Good Example
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Jumbo Add Component is an agent skill from jumbocontext/cli. Use liberally when you create, discover, or modify a software component. Registers the component with Jumbo so future sessions have accurate architectural context.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Memory and Context Orchestration for Coding Agents. The licence is AGPL-3.0.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/jumbo-add-component”

What it can do on your machine

Read from SKILL.md and the folder at commit a02a339. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

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

  • Network

    No URLs in SKILL.md.

    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

Jumbo Add Component loads about 446 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 102 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~446

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.

description
Use liberally when you create, discover, or modify a software component. Registers the component with Jumbo so future sessions have accurate architectural context.

Add Component

Register a software component with Jumbo when you create one, discover an unregistered one, or significantly change one's responsibility.

Before Adding

Check for an existing component to avoid duplication. Consider renaming, updating, or deprecating and replacing a previously registered component before registering a new one.

Use the search subcommand to locate previously registered components:

bash
jumbo components search -q <query>

Command Syntax

bash
jumbo component add \
  --name "<ComponentName>" \
  --type "<service|db|queue|ui|lib|api|worker|cache|storage>" \
  --description "<What the component does>" \
  --responsibility "<Single responsibility>" \
  --path "<file-path>"

Bad Example

bash
jumbo component add \
  --name "Utils" \
  --type "lib" \
  --description "Helper functions" \
  --responsibility "Various utilities" \
  --path "src/utils.ts"

Vague name, description, and responsibility. A future agent cannot determine what this component does or whether to use it.

Good Example

bash
jumbo component add \
  --name "EventStreamProjectionBuilder" \
  --type "service" \
  --description "Rebuilds materialized projections from event streams by replaying events through registered projection handlers" \
  --responsibility "Projection rebuilding from event history" \
  --path "src/infrastructure/projections/EventStreamProjectionBuilder.ts"

Name is self-documenting. Description and responsibility tell a future agent exactly what the component does and when to interact with it.
