feat(compat): OpenHands listing and daily-seeded agent order

[piyushbag]

Summary

Batched compatibility updates (supersedes #202):

Issue	Change
#26	Add OpenHands to the compatibility section
#7	Replace per-load Math.random shuffle with a date-seeded order so the marquee and expanded grid stay stable through the day

Both views now use the same shuffledAgents list, so the carousel and expanded grid do not drift apart.

---

OpenHands (#26)

Adds OpenHands to the compatibility section now that support for root-level AGENTS.md is documented and implemented in the OpenHands SDK.

Evidence

When #26 was opened, OpenHands did not document AGENTS.md support. That has since changed:

• Docs: https://docs.openhands.dev/overview/skills describes root-level AGENTS.md as always-on context injected at conversation start.
• SDK: load_project_skills() in OpenHands/software-agent-sdk loads third-party files including AGENTS.md from the git repo root via PATH_TO_THIRD_PARTY_SKILL_NAME and find_third_party_files(). Loaded with trigger=None, so content is always active in the system prompt.

Changes

• components/CompatibilitySection.tsx — add OpenHands entry linking to official skills docs
• public/logos/openhands-light.svg — logo from OpenHands branding assets
• public/logos/openhands-dark.svg — dark-mode variant

Screenshots

Scope notes

• Links to OpenHands skills documentation (not the deprecated all-hands.dev URL from the original issue)
• Does not claim support for @-style file imports or optional spec extensions beyond root AGENTS.md loading

---

Daily-seeded order (#7)

Issue #7 asked for a stable compatibility order instead of reshuffling on every page load.

Approach

• getDailySeed() derives a numeric seed from the current UTC date (YYYYMMDD)
• seededShuffle() applies Fisher–Yates with a deterministic PRNG from that seed
• Marquee rows and the expanded grid both read from shuffledAgents, so order stays consistent through the day

Why this shape

• Matches the issue suggestion of date-based rotation (similar to c4model colour variety)
• Avoids layout churn on every refresh while still rotating over time
• Single shuffle path shared by marquee and grid

---

How verified

• pnpm exec next build — compiled successfully, static pages generated
• npx tsc --noEmit — pass
• OpenHands SDK source confirms AGENTS.md is loaded from repo root (case-insensitive filename match)
• Local dev — OpenHands visible in expanded compatibility grid; marquee/grid use same daily order

[vercel]

Someone is attempting to deploy a commit to the openai Team on Vercel.

A member of the Team first needs to authorize it.

[piyushbag]

Thanks for the review. I batched the two compatibility changes into this PR:

• Order of displaying tools in the compatibility section #7 — daily-seeded order (marquee + grid now both use the same shuffledAgents list)
• Confirm if OpenHands supports AGENTS.md #26 — OpenHands entry + light/dark logos

Local verification on the updated branch:

pnpm exec next build
✓ Compiled successfully
✓ Generating static pages (3/3)

I will close #202 as superseded by this branch. Let me know if you want the seed cadence changed (daily vs hourly) or any tweak to the OpenHands docs link before merge.

Merge and implement agents

Following up after re-checking this branch against current main (2026-06-28).

Status

• Branch is up to date with main (no rebase needed).
• Local verification on fix-daily-seeded-compatibility-order:
  • pnpm exec tsc --noEmit — pass
  • pnpm exec next build — pass (static pages generated)
• Add OpenHands to compatibility section #202 remains closed as superseded by this PR.

Review notes

• Batch (Order of displaying tools in the compatibility section #7 daily-seeded order + Confirm if OpenHands supports AGENTS.md #26 OpenHands) is implemented in one commit as requested.
• On "Please add PR/Readme to this": the PR body already documents approach, evidence, scope limits, and screenshots. Merged compatibility PRs in this repo (for example Add goose to compatibility section #109, Add Windsurf to compatibility section #111, Add Augment Code CLI as a compatible agent #156) typically touch only CompatibilitySection.tsx plus logo assets, not README.md. If you want a README update as well, let me know the preferred section/wording and I will add it in a follow-up commit.

CI

• Vercel checks still show "Authorization required to deploy" for fork PRs against the OpenAI team project. That requires maintainer-side authorization/re-run; it is not a code failure on this branch.

This PR fixes #7 and #26 and is ready for maintainer review/merge when convenient.
