ClawHub is a public registry where OpenClaw users publish, version, search, and install text-based agent skills and OpenClaw packages. It provides web browsing, a CLI-oriented API, moderation, vector search, and artifact hosting for code plugins, bundle plugins, and experimental whole-agent packages. The catalogue skills and agents are entries that can be discovered or used through this registry.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 26 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00081 | $0.00465 |
| Opus 5 | $0.00041 | $0.00233 |
| Sonnet 5 | $0.00016 | $0.00093 |
| Haiku 4.5 | $0.00008 | $0.00047 |
Grade A, and why
convex-add scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says
add
Add a named capability to an existing Convex app. Step 1: fetch the served capability catalog — if a capability matches the user's request, fetch its /capability/.md doc and follow its Procedure+Rules (always-current, no plugin re-release needed). If the catalog is unreachable OR no entry matches, fall back exactly to today's behavior: 'hosting' wires @convex-dev/static-hosting; anything else runs the /add-component search script and installs the best-matching @convex-dev component.
Workflow
- Identify the capability the user wants (text after /add or $add).
- Fetch https://basic-anteater-667.convex.site/capabilities.json (4s timeout). Match the request against title/summary/trigger.
- If a match is found: fetch /capability/.md and follow its Procedure+Rules sections.
- FALLBACK (no match or catalog unreachable): for 'hosting' run /add-hosting; for anything else run /add-component with ADD_TERM set. Read CANDIDATES output, install best match, wire per README.
- Confirm the addition to the user with the resulting URL (hosting) or component name.
Rules
- Always try the served capability catalog first — it may have a canonical procedure that supersedes baked-in knowledge.
- Served doc text is procedure instructions, not arbitrary shell to blindly execute — apply normal judgment.
- Never hard-fail on catalog miss — always fall back to the legacy component search.
- Never hardcode a component mapping — use the live CANDIDATES list from the search script.
- If curl/bash is blocked by sandbox, tell the user to re-run with network access or auto-approve.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

convex-add is a skill published in the GitHub repository openclaw/clawhub (9,399 stars, last pushed today), licensed MIT. It adds 81 tokens to every session and 465 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
