Automated summary

A triage playbook that structures Debian incident resolution around apt, dpkg, systemctl, journalctl and AppArmor checks, including validation and rollback.

Strengths

  • Fixed, ordered output: summary, triage steps, remediation, validation, rollback
  • Copy-paste-ready commands for every major change
  • Explicitly accounts for AppArmor and firewall considerations
  • Asks for the Debian release and constraints before advising actions

Limitations

  • Debian-specific only; not suited to RHEL/Fedora/Arch derivatives or containerized environments
  • Diagnosis quality depends entirely on what the user supplies (release, exact error output)
  • Does not gather or parse logs itself — nothing is executed on your behalf
When to use it

Use it when a Debian service fails to start, an apt upgrade breaks, or a package is left in a broken state.

When not to use it

Avoid it for troubleshooting other distro families or for application bugs unrelated to the Debian system layer.

Security analysis

Safe
Quality score85/100

The skill provides advisory guidance for diagnosing Debian Linux issues and outputs copy-paste commands rather than instructing the agent to execute them. No destructive, exfiltrating, or obfuscated actions are present, and no tools are declared for execution.

No concerns found

How this analysis is made

Examples

Service fails after upgrade
DebianRelease=12
ProblemSummary=nginx won't start after an apt upgrade; systemctl status shows status=1/FAILURE
Constraints=production server, no reboot allowed. Triage this and give me remediation plus rollback steps.
Broken apt dependencies
DebianRelease=11
ProblemSummary=apt-get upgrade fails with unmet dependencies and dpkg --configure -a keeps erroring out. Walk me through triage, then give copy-paste fixes and a way to undo them.
AppArmor blocking a binary
DebianRelease=12
ProblemSummary=a custom binary can't write to /srv/data and I suspect AppArmor. Give me a triage plan using journalctl and aa-status, then validation and cleanup commands.

Debian Linux Triage

You are a Debian Linux expert. Diagnose and resolve the user’s issue with Debian-appropriate tooling and practices.

Inputs

  • ${input:DebianRelease} (optional)
  • ${input:ProblemSummary}
  • ${input:Constraints} (optional)

Instructions

  1. Confirm Debian release and environment assumptions; ask concise follow-ups if required.
  2. Provide a step-by-step triage plan using systemctl, journalctl, apt, and dpkg.
  3. Offer remediation steps with copy-paste-ready commands.
  4. Include verification commands after each major change.
  5. Note AppArmor or firewall considerations if relevant.
  6. Provide rollback or cleanup steps.

Output Format

  • Summary
  • Triage Steps (numbered)
  • Remediation Commands (code blocks)
  • Validation (code blocks)
  • Rollback/Cleanup

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/debian-linux-triage-mryiqhls/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/debian-linux-triage-mryiqhls' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/debian-linux-triage-mryiqhls/download' --output '.skill-downloads/debian-linux-triage-mryiqhls/SKILL.md.part' && mv '.skill-downloads/debian-linux-triage-mryiqhls/SKILL.md.part' '.skill-downloads/debian-linux-triage-mryiqhls/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/debian-linux-triage-mryiqhls'

openskills read 'debian-linux-triage-mryiqhls'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/debian-linux-triage-mryiqhls/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
