Create prompts for sidecar workspaces. An agent skill from marcus/sidecar.

Modifying prompts in sidecar config files
SKILL.md covers Config File Locations, Config Format, Prompt Fields and Template Variables, plus 4 more sections
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Create Prompt is an agent skill from marcus/sidecar. Create prompts for sidecar workspaces. Covers prompt structure (name, ticketMode, body), template variables (ticket with fallbacks), config file locations (global vs project), and scope overrides. Use when creating or modifying prompts in sidecar config files.

Its SKILL.md is about 1.1k 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 Development. The repository describes itself as: Use sidecar next to CLI agents for diffs, file trees, conversation history, and task management with td. The licence is MIT.

When your agent uses it

Modifying prompts in sidecar config files

Example prompts

“/create-prompt”

What it can do on your machine

Read from SKILL.md and the folder at commit 3792a4e. 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 json).
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

Create Prompt loads about 1.1k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 301 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~69
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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: Create prompts for sidecar workspaces. Covers prompt structure (name, ticketMode, body), template variables (ticket with fallbacks), config file locations (global vs project), and scope overrides. Use when creating or modifying prompts in sidecar config files.

Creating Prompts

Prompts are reusable templates that configure the initial context for agents when creating workspaces. They help standardize common workflows like code reviews, bug fixes, or feature implementation.

Config File Locations

Scope	Path	Override Priority
Global	`~/.config/sidecar/config.json`	Lower
Project	`.sidecar/config.json` (in project)	Higher

Project prompts override global prompts with the same name (case-sensitive match).

Config Format

json

{
  "prompts": [
    {
      "name": "Code Review",
      "ticketMode": "optional",
      "body": "Do a detailed code review of {{ticket || 'open reviews'}}.\nFocus on correctness, edge cases, and test coverage."
    }
  ]
}

Prompt Fields

name (required)

Display name shown in the prompt picker. Keep it concise.

ticketMode (optional)

Controls how the ticket/task field behaves:

Mode	Behavior
`optional`	Task field shown, can be empty (default)
`required`	Task must be selected before creating
`none`	Task field is hidden, prompt stands alone

body (required)

The prompt text sent to the agent. Supports template variables. Use \n for newlines.

Template Variables

`{{ticket}}`

Expands to the selected task ID. Returns empty string if no task selected.

json

"body": "Fix issue {{ticket}}."
// With task td-abc123: "Fix issue td-abc123."
// Without task: "Fix issue ."

`{{ticket || 'fallback'}}`

Expands to task ID, or the fallback text if no task selected.

json

"body": "Review {{ticket || 'all open items'}}."
// With task td-abc123: "Review td-abc123."
// Without task: "Review all open items."

Only single quotes work for fallback text:

{{ticket || 'default'}} -- works
{{ticket || "default"}} -- does NOT work

Examples

Task-Required Workflow

json

{
  "name": "Implement Task",
  "ticketMode": "required",
  "body": "Begin work on {{ticket}}. Use td to track progress.\nRead the task description carefully before starting."
}

Standalone Workflow

json

{
  "name": "Run Tests",
  "ticketMode": "none",
  "body": "Run the full test suite. Fix any failures.\nReport a summary when complete."
}

Flexible Workflow

json

{
  "name": "Code Review Session",
  "ticketMode": "optional",
  "body": "Start a review session for {{ticket || 'open reviews'}}.\nCreate td tasks for any issues found."
}

json

{
  "name": "Backlog Refinement",
  "ticketMode": "none",
  "body": "Start a backlog refinement session. Use td to find all tasks in the backlog starting with the oldest. For each task:\n\n1. Determine relevance - has it been implemented, is it still needed? If not relevant, comment on the task and close it. If questionable, leave open with notes.\n\n2. Update tasks with out-of-date code references to reflect the current state of the codebase.\n\nUse sub-agents to analyze multiple tasks in parallel. Present a report of findings and changes when complete."
}

Default Prompts

If no config file exists, the app creates one with 5 built-in templates:

Begin Work on Ticket (required)
Code Review Ticket (required)
Plan to Epic (No Impl) (none)
Plan to Epic + Implement (none)
TD Review Session (none)

Press d in the prompt picker to install defaults if none are configured.

Scope Indicators

In the prompt picker, prompts show their source:

[G] - Global prompt (from ~/.config/sidecar/)
[P] - Project prompt (from .sidecar/)

Important Notes

Prompt names must match exactly (case-sensitive) for project overrides
Only single quotes work in fallback syntax
ticketMode defaults to optional if omitted
Config files are loaded when creating a workspace; restart the app to reload
Keep names short (they appear in a table with limited width)
Use \n for newlines in prompt bodies
