quick

quick is a skill for Claude Code, Codex from samibs/skillfoundry. It costs 8 tokens per session (1,314 once invoked), scanned A, original, MIT.

A lightweight workflow for small software changes: implement the change, run tests, and optionally create a Git commit. TDD, or test-driven development, means using tests to guide the implementation when the scope is clear.

In plain words
What is it for?
Use it for small features, configuration changes, utilities, prototypes, and UI tweaks that need implementation, testing, and optionally a scoped commit.
Why use it?
It gives small tasks a short, repeatable process without requiring a full product-planning pipeline. The test loop catches problems before the change is committed.

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 1 finding 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 yesterday.

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.

Expected in a hook, worth knowing in a rule or an instructions file.

The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/quick — Lightweight Feature Workflow

Role: Minimal-ceremony feature workflow for solo developers and small changes. Implement → test → commit. No PRD required, no full pipeline overhead.


Usage

/quick "description"          Implement, test, and commit a small feature
/quick "description" --challenge   Add evaluator challenge (optional)
/quick "description" --no-commit   Implement and test, skip commit

When to use

  • Solo developer, informal feature request
  • Small improvements (a flag, a config option, a new utility function)
  • Prototyping before formalizing into a PRD
  • Dark mode toggle, UI tweaks, non-critical additions

When NOT to use

  • Production auth, payments, security-critical features → use /feature
  • Multi-story features → use /forge
  • When you need the full evaluator + docs pipeline → use /feature

The Pipeline

/quick "add dark mode toggle to settings page"

  STEP 1: IMPLEMENT    Coder builds it (TDD when test scope is clear)
  STEP 2: TESTLOOP     Tests run, fixes loop until green (max 3 iterations)
  STEP 3: COMMIT       Scoped commit [ADVISORY if no shell]

  Optional (--challenge flag only):
  STEP 2.5: CHALLENGE  Evaluator grades. Fix brief loops back to coder.

No shadow tester. No Anvil gates. No layer-check. No docs stage (code-level comments only). No security audit.


Behavior

Step 1: Implement

Coder reads the description and implements:

  • If test scope is obvious (function, endpoint, component) → TDD: test first
  • If test scope is unclear (UI tweak, config change) → implement then test
  • Banned patterns still apply (no TODO, STUB, hardcoded secrets)
  • No formal story scaffolding required

Step 2: TestLoop

Run /testloop with reduced settings:

/testloop --max 3 [auto-detected scope]

Max 3 iterations (vs. 5 in full /feature). If not converging after 3, report failures and stop — no further auto-fix. User decides next action.

Step 2.5: Challenge (optional, --challenge flag only)

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 skill published in the GitHub repository samibs/skillfoundry (12 stars, last pushed today), licensed MIT. It adds 8 tokens to every session and 1,314 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
