💡 Motivation and Context

The agent instructions contain stale references or repeat details maintained elsewhere. Keep repository-specific safeguards and make the instructions easier to use for focused SDK changes.

Clarify the published-spec review exemption and remove duplicated contributor-guide descriptions. Document separate checks for the root, otel, and posthogmcpsdk modules, including temporary-copy checks against the pinned released core SDK. Specify GOFLAGS=-mod=mod for both pinned-core build and vet, matching CI while keeping checksum changes out of the checkout.

💚 How did you test it?

Checked local Markdown links, exact Git path casing, anchors, code fences, whitespace, changed-file scope, and preservation of the API approval and scoped spec-review rules. Verified the pinned-core commands against the CI workflow. SDK runtime builds and tests were not run for this documentation-only change. Autoreview was skipped because every changed file is documentation.

📝 Checklist

• I reviewed the submitted changes.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

No SDK code changes. Runtime tests and release changesets are not needed for this documentation-only PR.

If releasing new changes

• Ran pnpm changeset to generate a changeset file

Not applicable. This PR does not release SDK changes.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Tools: Pi, Git, and GitHub CLI. The SDK-wide documentation audit used Pi subagents for implementation and independent reviews. The human driver approved the audit and simplification plan. Useful details were moved to focused local guides rather than deleted. Human review is still required. No public session link is available.

[Low risk] Updates developer guidance and documentation.

The PR appears safe to merge, though the pinned-core check should be made reproducible for contributors.
