Wf Player

What it does

When your agent uses it

• Tasks that involve Session handoff
• Tasks that involve Subagents

Example prompts

• “wf-player”
• “/wf-player”
• “/wf-player”

Requirements

• Pre-approved tools (allowed-tools): Agent(*), AskUserQuestion(*), Read(*), Write(*), Edit(*), Bash(*), Glob(*), Grep(*), Skill(*)

Workflow steps

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

3. 3Instantiate
4. 4Execute Loop
5. 5Complete

What it can do on your machine

Read from SKILL.md and the folder at commit 07491b0. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Agent(*)
  • AskUserQuestion(*)
  • Read(*)
  • Write(*)
  • Edit(*)
  • Bash(*)
  • Glob(*)
  • Grep(*)
  • Skill(*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • node

  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

Wf Player loads about 1.3k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 346 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~93

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

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

• NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

  allowed-tools: Agent(*), AskUserQuestion(*), Read(*), Write(*), Edit(*), Bash(*), Glob(*), Grep(*), Skill(*)

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

Workflow template player — load a JSON template produced by wf-composer, bind context variables, execute nodes in DAG order (serial/parallel), persist state at checkpoints, support resume from any checkpoint. Uses ccw-coordinator serial-blocking for CLI nodes and team-coordinate worker pattern for parallel agent nodes. Triggers on "wf-player " or "/wf-player".

Skill(skill="wf-player", args="<template> --context goal='...'")
  |
  +-- Phase 0: Entry Router
       |-- --list        -> list available templates, exit
       |-- --resume      -> load session, skip to Phase 3 (Execute)
       |-- --dry-run     -> load + show execution plan, no execution
       |-- default       -> Phase 1 (Load)
  |
  +-- Phase 1: Load & Bind
  |    Load template JSON, bind {variables} from --context, validate required vars
  |
  +-- Phase 2: Instantiate
  |    Init session state, topological sort, write WFR session file
  |
  +-- Phase 3: Execute Loop
  |    For each node in order:
  |      skill node   -> Skill(skill=...) [synchronous]
  |      cli node     -> ccw cli [background + stop, hook callback]
  |      command node -> Skill(skill="namespace:cmd") [synchronous]
  |      agent node   -> Agent(...) [run_in_background per node config]
  |      checkpoint   -> save state, optionally pause
  |
  +-- Phase 4: Complete
       Archive session, output summary

Available workflow templates:
  feature-tdd-review    [feature, complex]   3 work nodes, 2 checkpoints
  quick-bugfix          [bugfix, simple]     2 work nodes, 1 checkpoint
