review-changes

review-changes is a skill for Claude Code, Codex from appclawhq/AppClaw. It costs 104 tokens per session (1,366 once invoked), scanned A, original, Apache-2.0.

A review procedure for changes in AppClaw, checking its command-line tool, VS Code extension, and natural-language YAML flow parsing together.

In plain words
What is it for?
Use it to inspect a diff, compare command-line events with extension handling, check environment-variable settings, and test affected YAML flow formats.
Why use it?
It catches mismatches where one part changes without the other, as well as configuration and parsing regressions that can otherwise fail quietly.

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

review-changes 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.

Review Changes

This skill reviews code changes in AppClaw to catch breakage across two surfaces (CLI and VSCode extension) and validate YAML flow parsing. AppClaw has a fragile contract between these surfaces — the CLI emits NDJSON events that the extension parses, and changes to either side can silently break the other.

Why this matters

AppClaw has three main failure modes when code changes:

  1. CLI ↔ Extension drift — The CLI's src/json-emitter.ts defines event types. The extension's vscode-extension/src/bridge.ts mirrors those types manually. When someone adds a field to one side, the other silently ignores it, causing subtle bugs.
  2. YAML flow parsing regressions — Natural language parsing in src/flow/natural-line.ts uses regex patterns that interact in surprising ways. A change to one regex can break another flow format.
  3. Config drift — The CLI reads env vars via src/config.ts (Zod schema). The extension maps VS Code settings to env vars in bridge.ts:getEnvFromSettings(). New config options added to one side may not appear in the other.

Review process

When triggered, perform these checks in order:

Step 1: Identify what changed

Run git diff (staged + unstaged) and git diff --cached to see all pending changes. Categorize the changed files:

  • Shared contract files (high risk): src/json-emitter.ts, src/flow/types.ts, src/config.ts
  • CLI-side flow files (medium risk): src/flow/natural-line.ts, src/flow/parse-yaml-flow.ts, src/flow/run-yaml-flow.ts, src/flow/variable-resolver.ts, src/flow/llm-parser.ts
  • Extension files (medium risk): anything under vscode-extension/src/
  • Other files (lower risk): agent, perception, vision, etc.

Step 2: Cross-surface consistency check

If any shared contract files changed, or if extension/CLI files changed:

Event type check:

  • Read src/json-emitter.ts (the JsonEvent type union)
  • Read vscode-extension/src/bridge.ts (the AppclawEvent type and individual event interfaces)
  • Compare every event variant — field names, types, optional vs required
  • Flag any mismatch (missing fields, type differences, new events not mirrored)

Changes

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.

review-changes is a skill published in the GitHub repository appclawhq/AppClaw (110 stars, last pushed yesterday), licensed Apache-2.0. It adds 104 tokens to every session and 1,366 once invoked, about $0.0005 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.
