DevServer: Skill for Claude Code

.claude/skills/devtask/SKILL.md

devtask is a skill for Claude Code from sergiovision/DevServer. It costs 31 tokens per session (704 once invoked), scanned A, original, MIT.

A task-writing assistant that turns a plain-language software request into one structured task record. The record includes a key, title, description, acceptance details, priority, labels, and execution settings.

In plain words
What is it for?
Use it to prepare a task for `POST /api/tasks`, including a concise specification, acceptance criteria, priority, labels, and autonomous execution settings.
Why use it?
It removes the formatting work needed to make an informal request ready for a task-management API. It also keeps the task focused on what should be done rather than guessing at repository details.

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

devtask 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 2mo 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.

DevTask - Generate Task JSON

You receive a free-form task description in $ARGUMENTS. Return only a single JSON object (no markdown fences, no explanation) that can be POSTed to POST /api/tasks.

Do NOT explore or read the target repo. The executing agent has full repo access — your job is to write a clear, compact spec from the user's description alone. Save tokens.

Output Schema

{
  "task_key": "<string>",
  "title": "<string>",
  "description": "<string>",
  "acceptance": "<string|null>",
  "priority": <1|2|3|4>,
  "labels": ["<string>", ...],
  "mode": "autonomous",
  "claude_mode": "api",
  "claude_model": "<string|null>",
  "max_turns": <number|null>,
  "skip_verify": false
}

repo_id is omitted — the caller supplies it.

Field Rules

  • task_key: UPPERCASE hyphenated slug, AREA-SHORT-SLUG format, max 64 chars.
  • title: Imperative, under 100 chars.
  • description: Concise actionable spec. State what to do, not how to find it. The executing agent will explore the repo itself — don't guess file paths or implementation details you don't know. Include edge cases only if obvious from the request.
  • acceptance: Bullet list of testable criteria, or null if trivial. Keep short — 2-5 bullets max.
  • priority: 1=critical/prod-down, 2=high/blocking, 3=medium (default), 4=low/cosmetic.
  • labels: 1-3 lowercase kebab-case. Common: feature, bug, refactor, ui, api, database, docs, security, performance, devops.
  • claude_model: null (repo default) for most tasks. "claude-sonnet-4-20250514" for simple/well-defined. "claude-opus-4-20250514" for complex/multi-file/security.
  • max_turns: Simple fix: 10-20. Small feature: 20-40. Medium: 40-60. Large: 60-100. Open-ended: null.
  • mode: Always "autonomous" unless explicitly interactive.
  • claude_mode: Always "api" unless user says Max.
  • skip_verify: Always false unless user says skip.

Rules

  1. Output ONLY valid JSON. No fences, no explanation.
  2. Do NOT include system fields: repo_id, id, status, created_by, created_at, updated_at, depends_on, bullmq_job_id.
  3. Never invent requirements not implied by the description.
  4. If description is too vague for acceptance criteria, set acceptance to null.

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.
