crawlkit

crawlkit is a skill for Claude Code, Codex from vincentkoc/dotskills. It costs 30 tokens per session (652 once invoked), scanned A, original, MIT.

A workflow for maintaining crawlkit, a shared Go library for archiving data from several related crawler applications. A shared library contains reusable code that other programs depend on.

In plain words
What is it for?
Use it when editing or reviewing crawlkit, moving common features into it, checking downstream compatibility, investigating shared interfaces or storage, or preparing a library release.
Why use it?
It keeps common archive features compatible across those applications and prevents app-specific behavior from leaking into the shared library.

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

crawlkit 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 5d 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.

Crawlkit

Purpose

Maintain crawlkit, the shared Go library for crawl app archive infrastructure. Use this skill to keep shared archive infrastructure reusable, tagged, and safe for downstream app branches.

When to use

  • Editing or reviewing crawlkit.
  • Moving common crawl app behavior into the library.
  • Checking whether gitcrawl, slacrawl, discrawl, or notcrawl can merge against a released crawlkit tag.
  • Preparing or verifying a crawlkit Go module release.
  • Investigating shared TUI, snapshot, config, SQLite, mirror, progress, or control metadata behavior.

Workflow

  1. Locate the crawlkit checkout from the current repository, an explicit user path, or the configured workspace root.

  2. Read repo-local AGENTS.md, README.md, CONTRIBUTING.md, and docs/publishing.md before release or compatibility work.

  3. Keep provider-specific logic out of crawlkit. Shared mechanics belong in packages such as config, store, snapshot, mirror, state, output, progress, tui, cache, and control.

  4. Run the library gate with workspace masking disabled:

    GOWORK=off go mod tidy
    git diff --exit-code -- go.mod go.sum
    GOWORK=off go vet ./...
    GOWORK=off go test -count=1 ./...
    
  5. For release checks, verify the signed tag and public Go proxy:

    git tag -v <version>
    GOPROXY=https://proxy.golang.org GONOSUMDB= go list -m github.com/vincentkoc/crawlkit@<version>
    
  6. For downstream readiness, inspect app branches read-only. Confirm they are clean, rebased, require the released crawlkit version, and pass:

    GOWORK=off go test ./...
    <app> --help
    <app> --version
    <app> metadata --json
    <app> status --json
    <app> tui --json
    
  7. Use temp HOME, XDG_CONFIG_HOME, and XDG_CACHE_HOME for CLI smokes. Never mutate live app archives.

Inputs

  • Target task: library edit, release verification, downstream readiness, or TUI backport.
  • Optional version tag such as v0.4.0.
  • Optional downstream app branch paths.

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.

crawlkit is a skill published in the GitHub repository vincentkoc/dotskills (102 stars, last pushed 13d ago), licensed MIT. It adds 30 tokens to every session and 652 once invoked, about $0.0002 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.
