mtk-agent-toolkit: Skill for Claude Code

.claude/skills/batch-fix/SKILL.md

batch-fix is a skill for Claude Code from moberghr/mtk-agent-toolkit. It costs 41 tokens per session (5,386 once invoked), scanned A, original, MIT.

A workflow for applying several small, independent corrective fixes across more than three files, without adding a new contract or changing the architecture.

In plain words
What is it for?
For applying multiple review fixes or small independent changes across a codebase.
Why use it?
It groups related review findings or small fixes into one controlled batch. It is intended for corrective work rather than new feature design.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is moberghr/mtk-agent-toolkit's own configuration. It tells Claude Code how to work on mtk-agent-toolkit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mtk-agent-toolkit configures →

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

batch-fix 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 8d 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.

MTK Batch-Fix — Corrective Batch Loop

MTK File Resolution

Resolve MTK skill/reference/script paths per .claude/references/mtk-file-resolution.md unless the router already stated MTK_ROOT=<path> this session; CLAUDE.md, .claude/tech-stack, .claude/rules/, tasks/, docs/, .mtk/ stay project-relative.


Overview

A lightweight loop for a corrective batch — several small, independent fixes applied together (e.g. "apply these 5 review findings", "fix these things"). It sits between fix (1-3 files, one coherent change) and implement (new behavior, public contract, or architecture).

batch-fix is deliberately not an implement rigor tier: implement makes the full spec/plan/approval apparatus mandatory at every level, so lightweight mode lives here as a sibling. The lightness is fixed: a short findings-list spec stub + tasks/todo.md, one approval gate on the list, inline execution (no subagent-per-batch), no docs/plans/ plan file, and proportional review. Any finding that grows into a new slice, contract, or re-planning escalates that finding to implement (see Scope Guard).

Source of truth for the composed workflow:

  • .claude/skills/context-engineering/SKILL.md
  • .claude/skills/fix/SKILL.md → Execute The Fix Workflow — reproduce, failing test first, and the test policy, for each behavioral finding
  • .claude/skills/security-and-hardening/SKILL.md — when a finding touches auth, audited state, secrets, or infra
  • .claude/skills/pre-commit-review/SKILL.md — always, before completion
  • .claude/skills/verification-before-completion/SKILL.md — before reporting done
  • .claude/skills/tech-stack-{stack}/SKILL.md — loaded based on .claude/tech-stack

When To Use

  • Applying a batch of review findings ("apply these findings", "apply the review comments")
  • A corrective batch of several distinct, unrelated small fixes ("fix these 5 things")
  • Cleanup sweeps that touch more than 3 files but introduce no new behavior

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.

batch-fix is a skill published in the GitHub repository moberghr/mtk-agent-toolkit (9 stars, last pushed 8d ago), licensed MIT. It adds 41 tokens to every session and 5,386 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
