pkgseek-linux

pkgseek-linux is a skill for Claude Code, Codex from web-casa/pkgseek-skills. It costs 120 tokens per session (1,132 once invoked), scanned A, original, MIT.

A Linux troubleshooting skill for investigating packages, build dependencies, shared libraries, binary compatibility, vulnerabilities, and distribution changes.

In plain words
What is it for?
Use it to diagnose Linux build errors, find packages that provide missing files, check vulnerabilities, compare distributions, and investigate ELF or ABI problems.
Why use it?
It helps identify why software cannot find a command, library, header, package, or compatible system component.

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

pkgseek-linux 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.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PkgSeek Linux Package and Compatibility Investigator

Use one installed Skill to route Linux package troubleshooting, security checks, migrations, ELF/ABI diagnostics, command portability, and container reviews to focused reference workflows.

Route the task

Read the matching reference file completely before investigating. Read more than one only when the request genuinely crosses capabilities; do not load all references by default.

User need Read this reference Primary PkgSeek MCP tools
Missing command, package, header, library, .pc file, or build dependency references/fix-linux-build-error.md diagnose_linux_error, query_file_provides, resolve_install, get_package

Core workflow

  1. Establish the exact Linux distribution, release, architecture, repository source, package build, and failure stage. Ask only for facts that materially change the conclusion.
  2. Select and read the relevant reference workflow above.
  3. Prefer the read-only PkgSeek MCP endpoint at https://api.pkgseek.com/mcp. Use https://api.pkgseek.com as a REST fallback only when MCP is unavailable.
  4. Prefer exact distro/release evidence over naming convention, upstream version guesses, or nearest-release matches. Separate fact, inference, and unknowns.
  5. Return the diagnosis, evidence chain, smallest supported remedy, non-mutating verification, and remaining uncertainty.

What ships with it

7 files 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.
