hatch3r-quick-change

hatch3r-quick-change is a command for Claude Code from hatch3r/hatch3r. It costs 24 tokens per session (8,150 once invoked), scanned A, original, MIT.

A lightweight command for making small code changes that are not tracked on a project board. It chooses how much planning, implementation, review, and testing the change needs.

In plain words
What is it for?
Use it for focused edits, small fixes, and short batches of related changes, including implementation, lint or type fixes, review, and testing when needed.
Why use it?
It avoids adding a full project-management process to a small change while still handling review or quality checks when the change is more involved.

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

hatch3r-quick-change 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 — 490 lines — stays where its author put it; the contents beside it link to each section on GitHub.

§0 Detect Ambiguity (P8 B1)

Before any action, scan the user's change description for unresolved questions in scope, target files, irreversibility, or constraint conflicts (multiple matching files, missing acceptance criteria, unclear rename target, ambiguous "small" boundary). If any are found, ask the user via the platform-native question tool per agents/shared/user-question-protocol.md — do not proceed under silent assumption. This is the default path, not an exception. Acceptable to proceed without asking ONLY when the change is single-file, single-concern, and the brief alone is testable (typo, constant tweak, single-line edit). The Step 2c "ASK" rule remains in force for residual ambiguity discovered mid-workflow.

Agent Pipeline

Stage Agent(s) Parallel Required
1. Scale Assessment Orchestrator (inline) No Yes
2. Implementation hatch3r-implementer (nontrivial items) Per item Nontrivial only
3. Lint Fix hatch3r-lint-fixer No When lint/type errors
4a. Review Loop hatch3r-reviewer -> hatch3r-fixer (max 3 iterations) No (sequential) Nontrivial only
4b. Final Quality hatch3r-testability + hatch3r-security Yes Nontrivial code changes

Parallel-safety conditions (per rules/hatch3r-agent-orchestration.md §Parallel Safety): every parallel fan-out above holds all three — read-only or disjoint writes (file- and contract-level), deterministic aggregation, no shared mutable state.

Browser Automation

At the start of this command, ask the user once:

"Would you like to enable browser verification for this session? This uses Playwright to test changes in the running application."

Browser-verification contract (spec-first, tiered): see commands/shared/orchestration-frame.md → Browser Verification (opt-in); protocol home rules/hatch3r-browser-verification.md. Per-command slot: when enabled, the implementation (Step 4) and review (Step 6) stages run browser-verification steps on UI-affecting items; if declined, skip every browser-verification step for the session and do not re-ask.

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.
