wf-start

An interactive tool for starting a Weft workflow, either from a saved template or from steps described by the user.

In plain words
What is it for?
It is for previewing available templates, selecting one, or starting an ad-hoc sequence such as plan, implement, and verify.
Why use it?
It helps choose or define an ordered workflow before work begins, so the process is explicit and repeatable.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wf-start scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Arguments

$ARGUMENTS

Instructions

If no arguments — guided template picker:

  1. List available templates with full details:

    python3 "${CLAUDE_PLUGIN_ROOT}/core/cli.py" start
    
  2. For each template, show a preview of its steps:

    python3 "${CLAUDE_PLUGIN_ROOT}/core/cli.py" preview <name>
    
  3. Present the user with a numbered list like:

    1. generic (3 steps) — plan, implement, verify
    2. feature-workflow (12 steps) — full-cycle feature development with guards
    3. Custom — describe your task and I'll build a workflow
    
  4. Wait for the user to pick a number, name, or describe their task.

    • If they pick a template: show the full preview and ask to confirm before starting.
    • If they describe a task: suggest appropriate steps, confirm, then start as ad-hoc.

If a template name is given:

  1. Preview it first:

    python3 "${CLAUDE_PLUGIN_ROOT}/core/cli.py" preview <template-name>
    
  2. Start it:

    python3 "${CLAUDE_PLUGIN_ROOT}/core/cli.py" start <template-name>
    

If comma-separated step names are given (ad-hoc):

python3 "${CLAUDE_PLUGIN_ROOT}/core/cli.py" start "step1,step2,step3"

After starting:

Display the workflow checklist and remind the user:

  • /wf-step complete to advance steps
  • /wf-status to check progress
  • /wf-analyze to review timing and recurring friction across runs
  • The Stop hook will prevent finishing with incomplete steps
  • If the current step has guards, explain what commands are blocked and why
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

wf-start is a skill published in the GitHub repository dioptx/weft (22 stars, last pushed 18d ago), licensed MIT. It adds 24 tokens to every session and 477 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
