What it does

Friday CLI is an agent skill from friday-platform/friday-studio. Interacts with a running Friday daemon via CLI and HTTP — lists/creates/modifies workspaces, triggers signals, watches sessions, publishes skills and agents. Use whenever you need to poke at a local Friday daemon, inspect its state, fire a signal, drive the autopilot / self-modification flywheel, create a workspace programmatically, or validate that a workspace.yml you just authored actually runs. Also use when the task involves $FRIDAYDURL, deno task atlas, curl-ing the daemon, or automating Friday itself.

Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/cli.md`, `references/http.md` and `references/recipes.md`).

It works with Deno. The repository describes itself as: Agent Harness Platform — shareable workspaces, MCP tools, skills, memory, and cron/webhook automations. Self-hosted and transparent.

When your agent uses it

  • Watches sessions
  • Publishes skills and agents
  • You need to poke at a local Friday daemon
  • Inspect its state

Example prompts

  • “Use the friday-cli skill to interact with a running Friday daemon via CLI and HTTP — lists/creates/modifies workspaces, triggers signals, watches…”
  • “/friday-cli”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. List workspaces and find IDs
  2. Inspect a workspace's signals before firing
  3. Fire a signal — three modes
  4. Watch a running session's agent activity + read the outcome
  5. Create a workspace from a workspace.yml

What it can do on your machine

Read from SKILL.md and the folder at commit fb3069a. 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:

    • curl
    • deno
    • jq
    • python3
    • bash

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

  • Network

    No URLs in SKILL.md. Its commands use curl, 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

Friday CLI loads about 4.3k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 132 tokens; SKILL.md has 1,964 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~132
When it runs · the whole SKILL.md, loaded when a task matches
~4.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~14k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:317
    ` — wipes `~/.friday/local/` (preserves `.env` and `bin/` only)

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,964 words (~4,293 tokens).

“Friday is orchestrated by a daemon at $FRIDAYD_URL. The exact scheme/port varies by install — installed Friday Studio runs on :18080 (with TLS configured automatically by the launcher), in-tree dev runs on :8080 (plain HTTP unless you opt in with…”
