html-skills-stop

html-skills-stop is a skill for Claude Code from f-labs-io/agent-html-skills. It costs 105 tokens per session (422 once invoked), scanned A, original, MIT.

A cleanup tool that stops the temporary local server used by interactive HTML tools in the current coding-agent session.

In plain words
What is it for?
Use it after finishing with interactive HTML editors or other HTML tools that send submitted results back to the coding agent.
Why use it?
It removes the temporary listener and related files when interactive HTML work is finished, so the session does not leave that service running.

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

html-skills-stop 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/stop.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

html-skills-stop — tear down server mode

Pairs with html-skills-listen. Runs a bundled script that kills this session's receiver and removes its temp files, then stops the Monitor task whose id html-skills-listen saved.

Steps

  1. Run the teardown script with this session's id:

    bash "${CLAUDE_PLUGIN_ROOT}/skills/html-skills-stop/scripts/stop.sh" "${CLAUDE_SESSION_ID}"

    Output: KEY=VALUE lines. Always: SID, STATUS. When a Monitor was armed by html-skills-listen and saved, also: MONITOR_ID.

  2. If MONITOR_ID is printed, stop the Monitor task:

    Call TaskStop(task_id: "<MONITOR_ID>"). If it fails because the task is already gone, that's fine — continue.

  3. Branch on STATUS:

    • STATUS=WEB — Tell the user: ✓ html-skills server was inactive (web mode).
    • STATUS=INACTIVE — Tell the user: ✓ html-skills server was already inactive — nothing to stop.
    • STATUS=STOPPED — Tell the user: ✓ html-skills server stopped for this session.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
