At a glance

Access and diagnose openSUSE Build Service (OBS) package build logs.

  • Works in 6 steps: Spec or packaging failure → Build dependency resolution failure → %build script failure → …
  • The user provides a build.opensuse.org live build log URL
  • SKILL.md covers Normalize The Input, Fetch The Log, Read The Failure From The Bottom and Classify The Failure, plus 2 more sections
  • Reaches build.opensuse.org and api.opensuse.org

What it does

Obs Build Logs is an agent skill from Nuitka/Nuitka. Access and diagnose openSUSE Build Service (OBS) package build logs. Use when the user provides a build.opensuse.org live build log URL, a package page, or a project/package/repository/arch tuple, or asks why an OBS RPM build failed. Prefer this skill for translating OBS URLs into raw log URLs, fetching public log output, and finding the actual failing step instead of earlier noise.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Translation. It works with Python. The repository describes itself as: Nuitka is a Python compiler written in Python. It's fully compatible with Python 2.6, 2.7, 3.4-3.14. You feed it your Python app, it does a lot of clever things, and spits out an… The licence is AGPL-3.0.

When your agent uses it

  • The user provides a build.opensuse.org live build log URL
  • A project/package/repository/arch tuple
  • Asks why an OBS RPM build failed

Example prompts

  • “/obs-build-logs”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Spec or packaging failure
  2. Build dependency resolution failure
  3. %build script failure
  4. %check test failure
  5. Compiler or linker failure
  6. Runtime failure in a smoke test

What it can do on your machine

Read from SKILL.md and the folder at commit 5efaf76. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • build.opensuse.org
    • api.opensuse.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Obs Build Logs loads about 849 tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 407 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~849

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Access and diagnose openSUSE Build Service (OBS) package build logs. Use when the user provides a `build.opensuse.org` live build log URL, a package page, or a `project/package/repository/arch` tuple, or asks why an OBS RPM build failed. Prefer this skill for translating OBS URLs into raw log URLs, fetching public `_log` output, and finding the actual failing step instead of earlier noise.

OBS Build Logs

Use the public logfile route first. The live-log page is often awkward to scrape, and the API _log route may require authentication.

Normalize The Input

Extract project, package, repository, and arch first.

  • Live log page: https://build.opensuse.org/package/live_build_log/<project>/<package>/<repository>/<arch>
  • Public raw logfile: https://build.opensuse.org/public/build/<project>/<repository>/<arch>/<package>/_log
  • API raw logfile: https://api.opensuse.org/build/<project>/<repository>/<arch>/<package>/_log

Remember the ordering difference:

  • live_build_log puts package second.
  • Raw _log URLs put package last.

Fetch The Log

Prefer the public raw logfile URL on build.opensuse.org.

  • It is the route OBS uses for the web UI "Download logfile" action.
  • Use the API route only when authentication is available or required.
  • On Windows, do not rely on osc for this unless it is already known to work in the current environment; recent osc builds may fail because they import fcntl.

If shell access is allowed, fetch the public log directly rather than the live page.

Read The Failure From The Bottom

Start near the end of the log and work upward.

Look for the first load-bearing failure marker near the bottom:

  • RPM build errors:
  • Bad exit status from ...
  • FATAL:
  • FAILED
  • Traceback
  • Error, results differed
  • compiler or linker error:

Treat earlier lines as suspect until the final failing section confirms they matter.

Common false leads:

  • early spec file parser line ... cannot expand %(...)
  • dependency cycle output during setup
  • unrelated package install warnings
  • earlier warnings that do not match the terminal failure
Show full SKILL.md (183 more words)Show less

Classify The Failure

Map the terminal failure to one of these buckets:

  1. Spec or packaging failure
  2. Build dependency resolution failure
  3. %build script failure
  4. %check test failure
  5. Compiler or linker failure
  6. Runtime failure in a smoke test

State explicitly which stage failed and quote the smallest useful log fragment.

Trace The Failure Back Into This Repository

For this repository, inspect these files first when the log points to packaging or OBS upload logic:

  • nuitka/tools/release/rpm/nuitka.spec
  • nuitka/tools/release/osc_upload/__main__.py
  • rpm/make-osc-upload.py
  • rpm/check-osc-status.py

If the failure is inside generated code, tests, or a runtime warning, inspect the named module or test file from the log before changing packaging.

Report The Result

Report these items in order:

  1. The exact stage that failed
  2. The real terminal error
  3. Why earlier warnings are or are not the root cause
  4. The local file or code path that should be changed
  5. The most direct fix or next verification step

If the public logfile fetch fails, say which URL variant was tried and whether the failure looks like bad path ordering, missing auth, or network restrictions.
