Issue being fixed or feature implemented

Agents producing often regressions tests and functional tests that could be significantly better.

What was done?

Pr adds better guidance for writing tests for agents.

How Has This Been Tested?

Let's see how agents will produce new PRs after.

why add indirection?

because Generate compile_commands.json` is very specific type of input that is used only for clang-tidy.
But it polutes common context by useless instruction.

Indirection is added to case, when agent need to run clang-tidy or build compile_commands.json otherwise I would remove this chapter at all.

Walkthrough

AGENTS.md and CLAUDE.md update development guidance. The changes revise RPC assertion wording, document functional tests for dashd, replace compile_commands.json generation instructions with clang-tidy guidance, and remove CI/lint backport references. They also add detailed rules for selecting, structuring, validating, and omitting unit and functional tests.

⚠️ DEGRADED — Final review — Phase 1 only (trivial change)

⚠️ DEGRADED review. The primary review models were unavailable (gpt-6-astra unavailable: All credentials for model gpt-6-astra are cooling down (last error: usage_limit_reached: The usage limit has been reache), so this review ran on stand-in models: gpt-5.6-lunamuse-spark-1.3-contributor, gpt-5.6-solmuse-spark-1.3-contributor, gpt-5.6-terramuse-spark-1.3-contributor, gpt-6-astramuse-spark-1.3-contributor. Both review phases and the independent verifiers still ran, but on weaker models, with Phase 1 capped at high effort. Treat the verdict as provisional; a full-strength re-review will run on the next push once the primary models are back.

Docs-only PR adding Writing Tests guidance is sound. Two minor in-scope wording fixes remain: an ungrammatical clang-tidy heading introduced by this PR, and a unit-test scope that omits src/wallet/test/ despite the same file listing it as a unit-test suite.

- [SUGGESTION] AGENTS.md:121-123: Fix mixed-grammar heading and cross-reference style for clang-tidy section
  This PR introduced the heading "Generate `compile_commands.json` or running clang-tidy:" which mixes imperative and gerund forms, and uses "chapter Running clang-tidy" while line 29 uses `under "..."` for the same document. Standardizing the phrasing and cross-reference removes the inconsistency introduced here. Applies equally to CLAUDE.md.
- [SUGGESTION] AGENTS.md:134: Reference src/wallet/test/ alongside src/test/ for unit tests
  The new Writing Tests bullet scopes unit tests to `src/test/` only, but the repository map and assertion guidance in the same file list both `src/test/` and `src/wallet/test/` as Boost C++ unit-test suites. Wallet contributors following the new text literally may place wallet unit tests in the wrong directory. Listing both paths fixes the gap. Applies equally to CLAUDE.md. `src/qt/test/` is intentionally left out here because it uses Qt Test, not Boost.

Re-review — Final review — Phase 1 only (trivial change)

The documentation changes address both previously reported issues. Two non-blocking documentation inconsistencies remain: the assertion guidance differs between the mirrored files, and the unit-test guidance incorrectly labels Qt tests as Boost tests. No blocking issues were verified.

In `CLAUDE.md`:
- [SUGGESTION] CLAUDE.md:51-52: CLAUDE.md assertions paragraph diverges from AGENTS.md, omits src/qt/test/
  The latest commit adds `src/qt/test/` to the assertion exemption in AGENTS.md but leaves the corresponding paragraph in CLAUDE.md unchanged. Both files explicitly require identical guidance, so agents now receive different assertion rules depending on which file they read. Apply the same Qt-test exemption in CLAUDE.md.

Distinguish the frameworks so agents select the correct test macros and runner. Apply the same correction to CLAUDE.md line 134.
