quick

A command for making small software changes without running the full development workflow. It is intended for focused fixes, refactors, documentation updates, and configuration changes.

In plain words
What is it for?
Use it for small bugs, single-file changes, variable renames, logging updates, comments, formatting fixes, and minor configuration edits.
Why use it?
It provides a shorter path for narrowly scoped work that does not need the planning and coordination used for a large feature.

Command for Claude Code

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.

Made for: Claude Code.

Per session 41 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 3,867 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

quick 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 516 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CRITICAL ARCHITECTURE (v2.0 - Task() Orchestrator Pattern):

This orchestrator is lightweight. You MUST:

  1. Parse arguments and validate scope (inline)
  2. Create branch (inline)
  3. Spawn isolated quick-worker agent via Task tool
  4. Handle Q&A when agent returns ---NEEDS_INPUT---
  5. Display summary from agent result

Benefits: Implementation is isolated, Q&A flows naturally, consistent with /feature and /epic patterns.

Current branch: !git branch --show-current

Recent commits (last 3): !git log -3 --oneline

Studio context (multi-agent isolation): !bash .spec-flow/scripts/bash/worktree-context.sh studio-detect 2>/dev/null || echo ""

Worktree context: !bash .spec-flow/scripts/bash/worktree-context.sh info 2>/dev/null || echo '{"is_worktree": false}'

<when_to_use>

Good Candidates (Use /quick)

  • Bug fixes: UI glitches, logic errors, null checks
  • Small refactors: Rename variables, extract functions, simplify logic
  • Internal improvements: Logging, error messages, constants
  • Documentation: README updates, code comments, docstrings
  • Style/formatting: Whitespace, naming conventions, linting fixes
  • Config tweaks: Environment variables, build settings, tool configs

Characteristics: <100 LOC, <5 files, single concern, no breaking changes, can implement in one sitting

Do NOT Use (Use /feature Instead)

  • New features with UI components - Needs design review and mockup approval
  • Database schema changes - Requires migration planning and zero-downtime strategy
  • API contract changes - Breaking changes need stakeholder review
  • Security-sensitive code - Auth, permissions, crypto need thorough review
  • Changes affecting >5 files - Coordination across modules needs planning
  • Multi-step features - Complex workflows need task breakdown

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.

quick is a command published in the GitHub repository marcusgoll/Spec-Flow (91 stars, last pushed 4mo ago), licensed MIT. It adds 41 tokens to every session and 3,867 once invoked, about $0.0002 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.
