sync-check

sync-check is a skill for Claude Code from ItamarZand88/CLI-Anything-WEB. It costs 95 tokens per session (1,811 once invoked), scanned A, original, MIT.

A documentation consistency checker for CLI projects. It follows the files that describe a tool—such as skills, operating instructions, READMEs, and plugin references—after code changes.

In plain words
What is it for?
Use it after fixing bugs, adding commands, changing authentication, or refactoring to find downstream documentation that needs updating.
Why use it?
It helps prevent documentation from describing old commands, output fields, authentication behaviour, dependencies, or examples after the code has changed.

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

sync-check 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 1mo 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.

Sync Check

After any code change, verify all related files are synchronized. This catches the "fixed the bug but forgot to update the skill/SOP/plugin docs" problem.

How to Use

Run /sync-check after making changes. It will:

  1. Detect what changed (from git diff or conversation context)
  2. Check all downstream files that depend on the change
  3. Report what's out of sync
  4. Offer to fix each one

The Dependency Web

Every change touches multiple files. Here's the full map:

Code Change → Documentation Updates

CLI code changed (client.py, commands/*.py, auth.py)
  ├── .claude/skills/<app>-cli/SKILL.md     (commands, output fields, examples)
  ├── <app>/agent-harness/<APP>.md           (SOP: rpcid table, data models)
  ├── <app>/agent-harness/cli_web/<app>/README.md  (usage examples, deps)
  ├── <app>/agent-harness/setup.py           (dependencies)
  └── <app>_cli.py _print_repl_help()        (REPL help must list all commands)

Bug Fix → Plugin Lesson Updates

Bug found and fixed in any CLI
  ├── Was it a pattern that could repeat in future CLIs?
  │   YES → Add to the relevant plugin reference file:
  │   ├── auth-strategies.md "Known Pitfalls" table    (auth bugs)
  │   ├── google-batchexecute.md                       (RPC/batchexecute bugs)
  │   ├── ssr-patterns.md "HTML Scraping Pitfalls"     (scraping bugs)
  │   ├── protection-detection.md                      (anti-bot/WAF bugs)
  │   └── traffic-patterns.md                          (protocol detection bugs)
  │
  ├── Is it a universal lesson (applies to ALL CLIs)?
  │   YES → Add to HARNESS.md "Lessons Learned" cross-reference table
  │
  └── Does it change a critical convention?
      YES → Update CLAUDE.md "Critical Conventions" section

New Command Added → Full Update Chain

New command added to a CLI
  ├── .claude/skills/<app>-cli/SKILL.md     (add command + options + output fields)
  ├── <app>_cli.py _print_repl_help()        (add to REPL help)
  ├── <app>/agent-harness/<APP>.md           (add endpoint to API map)
  ├── README.md (repo root)                  (if it changes the CLI's capabilities)
  └── Run: cli-web-<app> <new-cmd> --json    (verify output matches skill docs)

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.
