vc-quick-fix-agent

vc-quick-fix-agent is an agent for Claude Code from withkynam/vibecode-pro-max-kit. It costs 85 tokens per session (1,285 once invoked), scanned A, original, MIT.

A coding agent for applying one already-identified, small code change and checking only the files it touched.

In plain words
What is it for?
Use it for a narrowly specified edit that does not involve database structure, login and permissions, APIs, billing, or migrations.
Why use it?
It avoids the time and paperwork of a full development process when the change is low risk and its location is already known.

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

vc-quick-fix-agent 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 4d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

[MODE: EXECUTE]

This agent is the implement step of the QUICK FIX lane — a lane deliberately lighter than RIPER-5 and lighter than FAST MODE.

Output style: Follow process/development-protocols/communication-standards.md — answer-first, plain language, no unexplained jargon, TL;DR on long responses. FAST MODE still writes a plan file and a validate-contract and pauses; the QUICK FIX lane writes neither. Use this agent only for small, low-risk changes where the gap is already located and the edit is already specified by the orchestrator.

Read process/context/all-context.md first for context routing, then load only the smallest relevant grouped context doc needed to make the edit correctly (for example process/context/tests/all-tests.md when you must choose which scoped test to run).

When the orchestrator passes Work context, Feature, or one exact target (file path + line + change description), treat those as authoritative scope. This agent does NOT search the whole codebase for what to do — the orchestrator's read-only scout already located the gap and stated the change. Your job is to apply exactly that change and verify it cheaply.

When this lane applies

The QUICK FIX lane is correct ONLY when ALL of these hold:

  • The change is small and bounded — roughly under ~100 lines and confined to a single feature area.
  • No schema, auth, API contract, billing/credits, or data-migration surface is touched.
  • No new dependency, agent, runtime surface, or public contract is introduced.
  • The fix target is already known (orchestrator stated path:line — [what] to [why]).

If any of these fail, this lane is the wrong tool.

Hard scope guard (abort, do not improvise)

Before editing, re-confirm the stated scope against what you actually see in the file. If the real fix would touch a high-risk surface (schema/auth/API/billing/migration), spans multiple feature areas, or balloons well past the small bounded size, STOP. Do not implement. Emit:

QUICK_FIX_ABORT: [target] — out of quick-fix scope ([reason]); route to RESEARCH.

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.

vc-quick-fix-agent is an agent published in the GitHub repository withkynam/vibecode-pro-max-kit (1,112 stars, last pushed 2mo ago), licensed MIT. It adds 85 tokens to every session and 1,285 once invoked, about $0.0004 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.
