check-gotchas

check-gotchas is a command for Claude Code from GaZmagik/claude-memory-plugin. It costs 19 tokens per session (3,609 once invoked), scanned A, original, MIT.

A command for checking recent coding work against warnings and lessons saved in a memory system. It can examine all available memories, selected scopes, recent changes, staged changes, files, or topics.

In plain words
What is it for?
Use it to review a recent commit, uncommitted or staged changes, a specific file, or a topic for relevant warnings.
Why use it?
It helps catch known mistakes before they are repeated during ongoing work.

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

check-gotchas 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 6d 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.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Goal

Search the memory system for relevant gotchas, warnings, and learnings that apply to recent work. This is a proactive mistake-prevention check, not a git pre-commit hook.

By default, searches ALL accessible scopes (User → Project → Local) to ensure comprehensive gotcha coverage.

Execution Steps

1. Parse Arguments

Check for scope restriction:

  • --scope user or --scope global → Search user scope only
  • --scope project → Search project scope only
  • --scope local → Search local scope only
  • --scope enterprise → Search enterprise scope only (for managed environments)
  • No --scope specified → Search ALL accessible scopes (recommended)

Note: --scope global is accepted as a legacy alias for --scope user.

Check for work scope (what to check):

  • all or --all → Check all memories for gotchas (comprehensive review)
  • staged → Check only staged git changes
  • recent → Check recent work (last commit, uncommitted changes)
  • {file-path} → Check specific file or pattern
  • {topic} → Any other argument is treated as a topic to search for

If no arguments (default):

  • Check recent work (uncommitted changes + last commit)
  • If nothing recent, offer to check all gotchas

2. Determine Accessible Scopes

Check which scopes are accessible for searching:

# Check enterprise scope availability (for managed environments)
enterprise_enabled=$(memory config get scopes.enterprise.enabled 2>/dev/null | jq -r '.data // false')

# Check if in a git repo (for project/local scopes)
in_git_repo=$(git rev-parse --git-dir >/dev/null 2>&1 && echo "true" || echo "false")

Accessible scopes (in precedence order):

  1. User - always accessible
  2. Project - if in_git_repo is true
  3. Local - if in_git_repo is true
  4. Enterprise - if enterprise_enabled is true (for managed environments)

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.
