Summary of changes

Round 2 of AGENTS.md cleanups (follow-up to #8554), continuing the agents.md best practices "table of contents, not encyclopedia" principle.

Reason for change

Five targeted improvements: collapse provably redundant sections, drop stale references, fix broken formatting. Every line in AGENTS.md is loaded into agent context on every task, so redundant content has a real cost.

Implementation details

# Change
1 NuGet Package Architecture: collapse 3 sub-sections that all described the same package/DLL distinction into 2 paragraphs
2 Drop the stale **Reference:** See PR 7467... citation in Logging
3 Drop the generic **Filters:** --filter "Category=Smoke", --framework net6.0 line in Testing (derivable from dotnet test --help)
4 Trim Commit & PR Guidelines: drop universal git/PR advice (imperative mood, link issues, etc.); keep only the repo-specific [Area] prefix convention and the "keep concise" rule (the latter is specifically AI-relevant — agents tend to over-explain)
5 Reformat the multi-line supported-configurations.yaml Configuration bullet into a single line (was rendering oddly)

Net: +5 / -33 lines. AGENTS.md is now 305 lines.

Test coverage

N/A — documentation-only.

Benchmarks

Benchmark execution time: 2026-05-12 10:42:57

Comparing candidate commit 41344d6 in PR branch nacho/AgentsMdImprove2 with baseline commit d43a6e5 in branch master.

Some scenarios are present only in baseline or only in candidate runs. If you didn't create or remove some scenarios in your branch, this maybe a sign of crashed benchmarks 💥💥💥
Check Gitlab CI job log to find if any benchmark has crashed.

Found 3 performance improvements and 5 performance regressions! Performance is the same for 45 metrics, 19 unstable metrics, 93 known flaky benchmarks, 33 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

  • 🟩 = significantly better candidate vs. baseline
  • 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
