What is mongez-agent-kit-troubleshooting?

A troubleshooting guide for common problems with @mongez/agent-kit, a tool that installs and synchronizes coding-agent skills.

It helps diagnose setup and sync issues involving the agent-kit command, installed packages, skill folders, AGENTS.md files, and published packages.

It connects error messages and symptoms to likely causes and practical fixes, including missing commands, unseen skills, package-name collisions, and synchronization failures.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00141	$0.02327
Opus 5.5	$0.00056	$0.00931
Sonnet 5.5	$0.00028	$0.00465
Haiku 4.5	$0.00014	$0.00233

Security

Grade A, and why

mongez-agent-kit-troubleshooting 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.

How it starts

The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Troubleshooting

Symptom → cause → fix. Find the line that matches what you hit.

Auto-trigger: user reports any error/log line from agent-kit init, agent-kit sync, or agent-kit watch; user says "command not found", "skills not showing up", "wrong package", "pick matched no installed packages", "collision", "AGENTS.md missing", "my skill folder disappeared"; user asks "why doesn't X work" after running an agent-kit command.

Skip when: the question is about how to use a feature (CLI usage, configuration, monorepos) rather than a malfunction.

`agent-kit: command not found`

Symptom. postinstall: agent-kit sync runs but errors with command not found, or you typed agent-kit sync in a terminal and got the same.

Cause. The bare agent-kit binary only resolves when @mongez/agent-kit is installed locally (in the project's node_modules/.bin). The zero-install npx @mongez/agent-kit@latest init bootstrap installs nothing.

Fix. Install agent-kit as a dev dependency:

npm install -D @mongez/agent-kit
# or: yarn add -D @mongez/agent-kit / pnpm add -D @mongez/agent-kit

Now postinstall: agent-kit sync and any plain agent-kit sync invocation will resolve the local binary.

`npx agent-kit …` is fetching the wrong package

Symptom. npx agent-kit init (or sync) downloads and runs something unrecognizable — different help text, unfamiliar flags.

Cause. Without the scope, agent-kit resolves to a different, unrelated npm package when nothing is installed locally. npm doesn't fall back to scoped names.

Fix. Use the scoped name when running without a local install:

npx @mongez/agent-kit@latest init

After installing agent-kit as a dev dep, the unscoped npx agent-kit … is fine — npx prefers the local binary in node_modules/.bin.

Sync said it succeeded but my agent shows zero skills

Symptom. .claude/skills/ (or .cursor/skills/, .codex/skills/, …) exists and contains the expected folders, but the agent UI shows no skills.

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.
