I added the missing instructions to the existing parent update skill and
also added my scr migration skill

Definitely interesting.
As you might have noticed, I wrote a tool which can perform such
actions
like updating the parent pom across a large selection of repositories
using a coding agent.
Yes, I noticed the results :-)
I have also some skills flying around for the SCR annotation
migration
and parent pom updates :)
Maybe we can combine these into one. I'll have a look in the next
days.
I think that would be very useful. I definitely did not cover a lot of
repos during testing with the current skills and would be happy for any
enhancements.
Thanks,
Robert

Hi,
Updating the parent pom version in Sling modules is one task that
usually gets left behind. We have many modules, the work is not
that
rewarding and sometimes very tedious - for instance migrating
from
the
Felix SCR annotations to the official OSGi ones.
To make things simpler I have started an experiment in the
whiteboard
-
using agent skills [1] to upgrade the parent pom version.
I extended the experiment and created a tiny evaluation harness for
agent skills at [3] based on the Inpect framework [4].
I did some measurements of the skill and tried to answer some
questions
around efficiency and cost; captured the raw data at [5]:
1. Is the free variant gpt-oss-120b from openrouter good enough?
With skills it is good enough - sometimes better than haiku-4.5
from
Amazon Bedrock.
2. How big is the difference between haiku-4.5 and sonnet-4.5?
With skills the success rate is almost the same - haiku missed 1/15
of
the evals. But Sonnet ends up being almost 3.x more expensive.
3. How good is Claude Sonnet with or without skills?
The skills make all the difference.
Without skills Sonnet can only perform basic upgrades (100%) but it
fails in more complex cases:
- 20% success rate if the rat checks fail after upgrade
- 0% success rate if the build fails because of relocated
dependencies
(OSGi R6)
With skills Sonnet passes all 15 tests.
