+- Before merging any PR, verify TypeScript cleanly with `bunx tsc -p packages/schema/tsconfig.json --noEmit` and `bunx tsc -p packages/clawdhub/tsconfig.json --noEmit`; if Convex code changed, also run the repo typecheck path used by deploy so `bunx convex deploy` will not fail on `tsc`.

+## Convex Query & Bandwidth Rules
+- **Always use `.withIndex()` instead of `.filter()` for fields that can be indexed.** `.filter()` causes full table scans — every doc is read and billed. Even a single `.filter()` on a 16K-row table reads ~16 MB per call.
+- **Convex reads entire documents** — no field projections. If you only need a few fields from large docs (~6 KB+), denormalize a lightweight summary onto the parent doc or use a lookup table (see `embeddingSkillMap`, `skill.latestVersionSummary`, `skill.badges` for examples).
+- **Denormalization pattern**: persist computed fields so they can be indexed. Every mutation that updates source fields must also update the denormalized field. Always write a cursor-based backfill for new fields (see `backfillIsSuspiciousInternal`, `backfillLatestVersionSummaryInternal`, `backfillDenormalizedBadgesInternal` for examples).
+- **Cron jobs must never scan entire tables.** Use indexed queries with equality filters. Use cursor-based pagination for large datasets. Prefer incremental/delta tracking over full recounts.
+- **32K document limit per query.** Split `.collect()` calls by a partition field (e.g., one day at a time instead of a 7-day range). See `rebuildTrendingLeaderboardAction` in `convex/leaderboards.ts` for an example.
+- **Common mistakes**: `.filter().collect()` without an index; `ctx.db.get()` on large docs in a loop for list views; while loops that paginate the whole table to find filtered results.
+- **Before writing or reviewing Convex queries, check deployment health.** Run `bunx convex insights` to check for OCC conflicts, `bytesReadLimit`, and `documentsReadLimit` errors. Run `bunx convex logs --failure` to see individual error messages and stack traces. This helps identify which functions are causing bandwidth issues so you can prioritize fixes.

 # Changelog
 
+## Unreleased
+
+## 0.8.0 - 2026-03-13
+
+### Added

+- Skills/Web/API: surface platform/architecture labels and security evaluation results in v1 + inspect views (#499, #362).
+- API: add structured skill moderation responses plus `GET /api/v1/skills/{slug}/moderation` with redacted public evidence and full owner/staff detail (#334) (thanks @ArthurzKV).
+- Moderation: persist structured moderation snapshots (static scan + VT/LLM merged verdict, reason codes, and evidence) on skills and versions (#333) (thanks @ArthurzKV).
+- API: add scan security verification endpoint and non-suspicious filters (#820).
+- Users: add `trustedPublisher` flag and admin mutations to bypass pending-scan auto-hide for trusted publishers (#298) (thanks @autogame-17).
+- Moderation: add comment reporting with per-user active report caps, unique reporter/target enforcement, and auto-hide on the 4th unique report.
+- Moderation: add AI-driven comment scam backfill (`commentModeration:*`) with persisted verdict/confidence/explainer metadata and strict auto-ban for `certain_scam` + `high` confidence.
+- Admin: add manual unban for banned users (clears `deletedAt` + `banReason`, audit log entry). Revoked API tokens stay revoked.
+- Admin: bulk restore skills from GitHub backup; reclaim squatted slugs via v1 endpoints + internal tooling (#298) (thanks @autogame-17).

+
+### Changed
+- Skills: make published skill licensing explicit and fixed to MIT-0; require publish consent, surface no-attribution messaging in web/CLI/API, and remove per-skill license metadata.
+- Skill metadata: support env vars, dependency declarations, author, and links in parsed manifest metadata + install UI (#360) (thanks @mahsumaktas).
+- Rate limiting: apply authenticated quotas by user bucket (vs shared IP), emit delay-based reset headers, and improve CLI 429 guidance/retries (#412) (thanks @lc0rp).
+- Skills: reserve deleted slugs for prior owners (90-day cooldown) to prevent squatting; add admin reclaim flow (#298) (thanks @autogame-17).
+- Moderation: ban flow soft-deletes owned skills (reversible) and removes them from vector search (#298) (thanks @autogame-17).
+- Security/docs: document comment reporting/auto-hide behavior alongside existing skill reporting rules.
+- Security/moderation: add bounded explainable auto-ban reasons for scam comments and protect moderator/admin accounts from automated bans.
+- Moderation: banning users now also soft-deletes their authored comments (skill + soul), including legacy cleanup on re-ban.
+- Quality gate: language-aware word counting (`Intl.Segmenter`) and new `cjkChars` signal to reduce false rejects for non-Latin docs.
+- Jobs: run skill stat event processing every 5 minutes (was 15).
+- Deploy: add frontend/backend drift detection plus hardened production smoke/deploy checks.
+- API performance: batch resolve skill/soul tags in v1 list/get endpoints (fewer action->query round-trips) (#112) (thanks @mkrokosz).
+- LLM helpers: centralize OpenAI Responses text extraction for changelog/summary/eval flows (#502) (thanks @ianalloway).
+- Search/listing performance: cut embedding hydration and badge read bandwidth via `embeddingSkillMap` + denormalized skill badges; shift stat-doc sync to low-frequency cron (#441) (thanks @sethconvex).
+- Search/listing performance: move public browse/search hydration onto `skillSearchDigest`, add non-suspicious index paths, and split trending rebuilds to stay under Convex document limits.
+
+### Fixed
+- API: accept legacy CLI publish payloads during the v1 migration (#815).
+- Auth/UI: surface OAuth callback failures in the web UI instead of swallowing them (#688).
+- Skills: allow ownership healing when the previous owner was deleted/banned, and sanitize owner data in public payloads (#689, #793).
+- Skills/Web: debounce search URL updates on `/skills` to keep typing responsive, and cancel stale pending navigations on external query changes (#587) (thanks @neeravmakwana).
+- Upload: keep folder-picking enabled after page refresh by reapplying `webkitdirectory`/`directory` on the file input ref (#551) (thanks @MunemHashmi).

+- CLI: forward optional auth tokens for `search` and `explore` against authenticated registries (#608) (thanks @artdaal).
+- CLI: respect `HTTPS_PROXY`/`HTTP_PROXY`/`NO_PROXY` env vars for outbound registry requests, with troubleshooting docs (#363) (thanks @kerrypotter).
+- CLI: preserve registry base paths when composing API URLs for search/inspect/moderation commands (#486) (thanks @Liknox).
+- CLI: show manual URL guidance when automatic browser opening is unavailable; add regression tests for opener errors (#163) (thanks @aronchick).
+- API/CLI: expose skill security status in version inspect output, with schema wiring and CLI regression coverage (#362) (thanks @abutbul).
+- Moderation: remove over-broad keyword flags for common auth/payment/crypto terms so legitimate skills stop tripping regex prefilters (#273) (thanks @superlowburn).
+- Skills hard-delete: delete `commentReports` rows during moderation cleanup to avoid orphaned report records.
+- Comments: hide entries authored by deleted/deactivated users in `comments:listBySkill`.
+- Admin API: `POST /api/v1/users/reclaim` now performs non-destructive root-slug owner transfer
+  (preserves existing skill versions/stats/metadata) and clears active slug reservations.
+- VirusTotal: use shared AV-engine fallback verdict mapping for pending/backfill flows and keep undetected-only results pending (#591) (thanks @Shuai-DaiDai).
+- Skills/listing: keep non-suspicious browse pagination on one cursor family during `isSuspicious` backfill, and re-sync stale `latestVersionSummary` metadata fields (#572) (thanks @sethconvex).
+- PWA: update `manifest.json` branding so installed apps show the correct ClawHub name (#569) (thanks @Glucksberg).
+- Search/tests: cover soft-deleted skill filtering in vector hydration and lexical exact-slug fallback (#552) (thanks @MunemHashmi).
+- Docs/dev: fix local setup instructions for Node support, Convex env vars, frontend port, and post-seed stats refresh (#584) (thanks @jack-piplabs).

+# Contributing to ClawHub
+
+Welcome! ClawHub is the public skill registry for [OpenClaw](https://github.com/openclaw/openclaw). We appreciate bug fixes, documentation improvements, and feature contributions.
+
+- **Questions?** Ask in [#clawhub on Discord](https://discord.gg/clawd).
+- **Bug fixes** — PRs are welcome.
+- **New features or architectural changes** — please start with a Discord conversation in #clawhub first so we can align on scope.
+
+## Local Development Setup
+
+### Prerequisites
+
+- [Bun](https://bun.sh/) (Convex CLI runs via `bunx`, no global install needed)
+- [Node.js](https://nodejs.org/) v18, 20, 22, or 24 (required by the local Convex backend; v25+ is not yet supported)
+
+### Install and configure
+
+```bash
+bun install
+cp .env.local.example .env.local
+```
+
+Edit `.env.local` with the following values for **local Convex**:
+
+```bash
+# Frontend
+VITE_CONVEX_URL=http://127.0.0.1:3210
+VITE_CONVEX_SITE_URL=http://127.0.0.1:3210
+SITE_URL=http://localhost:3000
+
+# Deployment used by `bunx convex dev`
+CONVEX_DEPLOYMENT=anonymous:anonymous-clawhub
+```
+
+### GitHub OAuth App (for login)
+
+1. Go to [github.com/settings/developers](https://github.com/settings/developers) and create a new OAuth App.
+2. Set **Homepage URL** to `http://localhost:3000`.
+3. Set **Authorization callback URL** to `http://127.0.0.1:3210/api/auth/callback/github`.
+4. Copy the Client ID and generate a Client Secret.
+
+### Run the Convex backend
+
+Start the local Convex backend first — other setup steps depend on it:
+
+```bash
+bunx convex dev --typecheck=disable
+```
+
+### Set backend environment variables
+
+The Convex backend has its own env var store separate from `.env.local`. With the backend running, open a new terminal and set the required variables:
+
+```bash
+bunx convex env set AUTH_GITHUB_ID <your-client-id>
+bunx convex env set AUTH_GITHUB_SECRET <your-client-secret>
+bunx convex env set SITE_URL http://localhost:3000
+```
+
+### JWT keys (for Convex Auth)
+
+With the backend still running, generate the signing keys:
+
+```bash
+bunx @convex-dev/auth
+```
+
+This sets `JWT_PRIVATE_KEY` and `JWKS` on the Convex backend and outputs values you can also save to `.env.local` for reference.
+
+### Run the frontend
+
+```bash
+bun run dev -- --port 3000
+```
+
+Change the port if 3000 is already in use, and update `SITE_URL` in both `.env.local` and the Convex backend (`bunx convex env set SITE_URL ...`) to match.
+
+### Seed the database
+
+Populate sample data so the UI isn't empty:
+
+```bash
+# 3 sample skills (padel, gohome, xuezh)
+bunx convex run --no-push devSeed:seedNixSkills
+
+# 50 extra skills for pagination testing (optional)
+bunx convex run --no-push devSeedExtra:seedExtraSkillsInternal
+
+# Refresh the cached skills count (required after seeding)
+bunx convex run --no-push statsMaintenance:updateGlobalStatsInternal
+```
+
+To reset and re-seed:
+
+```bash
+bunx convex run --no-push devSeed:seedNixSkills '{"reset": true}'
+```
+
+### Optional environment variables
+
+These features degrade gracefully without their keys:
+
+| Variable | Purpose |
+|----------|---------|
+| `OPENAI_API_KEY` | Embeddings and vector search (falls back to zero vectors) |
+| `VT_API_KEY` | VirusTotal malware scanning |
+| `DISCORD_WEBHOOK_URL` | Discord notifications |
+| `GITHUB_APP_ID` / `GITHUB_APP_PRIVATE_KEY` / `GITHUB_APP_INSTALLATION_ID` | GitHub backup sync |
+
+## CLI Development
+
+The CLI source lives in [`packages/clawdhub/`](packages/clawdhub/). Both `clawhub` and `clawdhub` are registered as bin aliases.
+
+To test the CLI against your local instance:
+
+```bash
+CLAWHUB_REGISTRY=http://127.0.0.1:3210 CLAWHUB_SITE=http://localhost:3000 clawhub search "padel"
+```
+
+Manual smoke tests are documented in [`docs/manual-testing.md`](docs/manual-testing.md).
+
+## Skill & Soul Publishing
+
+- Skill format reference: [`docs/skill-format.md`](docs/skill-format.md)
+- Soul format reference: [`docs/soul-format.md`](docs/soul-format.md)
+- End-to-end walkthrough (search, install, publish, sync): [`docs/quickstart.md`](docs/quickstart.md)
+
+Quick publish:
+
+```bash
+clawhub publish <path-to-skill-directory>
+```
+
+## Before Submitting a PR
+
+```bash
+bun run lint       # oxlint
+bun run test       # Vitest (80% coverage threshold)
+bun run build      # Vite + Nitro
+```
+
+These are the same checks that run in CI (`.github/workflows/ci.yml`).
+
+**PR guidelines:**
+
+- Keep PRs focused — one concern per PR.
+- Use [Conventional Commits](https://www.conventionalcommits.org/): `feat:`, `fix:`, `chore:`, `docs:`, etc.
+- Include test commands and screenshots for UI changes.
+- Write a clear description of what changed and why.
+
+## AI-Generated Code
+
+AI-assisted contributions are welcome. When submitting AI-generated or AI-assisted code:
+
+- Note it in the PR description.
+- Describe the level of testing you applied.
+- Include prompts if useful for reviewers.
+- Confirm that you understand and can maintain the code.

+## OpenClaw Vision
+
+OpenClaw is the AI that actually does things.
+It runs on your devices, in your channels, with your rules.
+
+This document explains the current state and direction of the project.
+We are still early, so iteration is fast.
+Project overview and developer docs: [`README.md`](README.md)
+
+OpenClaw started as my personal playground to learn AI and build something genuinely useful:
+an assistant that can run real tasks on my computer.
+It evolved through several names and shells: Warelay -> Clawdbot -> Moltbot -> OpenClaw.
+
+The goal? A personal assistant that's easy to use, supports a wide range of platforms, and respects your privacy and security.
+
+The current focus is:
+
+Priority:
+- Security and safe defaults
+- Bug fixes and stability
+- Setup reliability and first-run UX
+
+Next priorities:
+- Supporting all major model providers
+- Improving support for major messaging channels (and adding a few high-demand ones)
+- Performance and test infrastructure
+- Better computer-use and agent harness capabilities
+- Ergonomics across CLI and web frontend
+- Companion apps on macOS, iOS, Android, Windows, and Linux
+
+## Security
+
+Security in OpenClaw is a deliberate tradeoff: strong defaults without killing capability.
+The goal is to stay powerful for real work while making risky paths explicit and operator-controlled.
+
+Canonical security policy and reporting:
+- https://github.com/openclaw/openclaw/blob/main/SECURITY.md
+
+We prioritize secure defaults, but we also expose clear knobs for trusted high-power workflows.
+
+## Plugins & Memory
+
+OpenClaw has an extensive plugin API.
+Core stays lean; optional capability should usually ship as plugins.
+
+Preferred plugin path is npm package distribution plus local extension loading for development.
+If you build a plugin, please host and maintain it in your own repository.
+The bar for adding optional plugins to core is intentionally high.
+
+Memory is a special plugin slot where only one memory plugin can be active at a time.
+Today we ship multiple memory options; over time we plan to converge on one recommended default path.
+
+### Skills
+
+We still ship some bundled skills for baseline UX.
+New skills should be published to ClawHub first (`clawhub.ai`), not added to core by default.
+Core skill additions should be rare and require a strong product or security reason.
+
+### MCP Support
+
+OpenClaw supports MCP through `mcporter`: https://github.com/steipete/mcporter
+
+This keeps MCP integration flexible and decoupled from core runtime:
+- add or change MCP servers without restarting the gateway
+- keep core tool/context surface lean
+- reduce MCP churn impact on core stability and security
+
+For now, we prefer this bridge model over building first-class MCP runtime into core.
+If there is an MCP server or feature `mcporter` does not support yet, please open an issue there.
+
+### Setup
+
+OpenClaw is currently terminal-first by design.
+This keeps setup explicit: users see docs, auth, permissions, and security posture up front.
+
+Long term, we want easier onboarding flows as hardening matures.
+We do not want convenience wrappers that hide critical security decisions from users.
+
+### Why TypeScript?
+
+OpenClaw is primarily an orchestration system: prompts, tools, protocols, and integrations.
+TypeScript was chosen to keep OpenClaw hackable by default.
+It is widely known, fast to iterate in, and easy to read, modify, and extend.
+
+## What We Will Not Merge (For Now)
+
+- New core skills when they can live on ClawHub
+- Commercial service integrations that do not clearly fit the model-provider category
+- Wrapper channels around already supported channels without a clear capability or security gap
+- First-class MCP runtime in core when `mcporter` already provides the integration path
+- Heavy orchestration layers that duplicate existing agent and tool infrastructure
+
+This list is a roadmap guardrail, not a law of physics.
+Strong user demand and strong technical rationale can change it.

+High-confidence scam patterns include:
+- Instructing users to run suspicious shell commands (especially obfuscated/base64/piped-to-bash/curl installer tricks).
+- Fake support/update instructions pointing to unknown domains, executables, or terminal one-liners.
+- Requests for private keys, seed phrases, passwords, API keys, session tokens, or wallet recovery data.
+- Impersonation or urgent pressure language to bypass trust checks.
+- Known scam payload structure (e.g. echo+base64+decode+bash, hidden downloader chains).
+
+Important anti-false-positive rules:
+- Do NOT mark legitimate troubleshooting or normal install instructions as "certain_scam" unless the malicious intent is explicit.
+- If suspicious but ambiguous, use "likely_scam".
