Do not just dump a raw diff — that's useless. Think about it.\n\nStep 1: Understand the skill's purpose.\nRead the LOCAL installed SKILL.md first. Understand what the skill does, what services it connects to, what credentials it uses, what commands it runs. Build a mental model of the skill.\n\nFor example:\n\nXcellent = X/Twitter growth tool → expects X API credentials, talks to api.x.com\nPiHole setup = DNS ad blocker → runs Docker commands, edits network config\nSpotify controller = music automation → uses $SPOTIFY_CLIENT_ID, talks to api.spotify.com\n\nStep 2: Read each remote file from the API response files array. Compare against local files line by line.\n\nFor each file, categorise changes:\n\nNew files added — what do they do? Are they scripts, configs, docs?\nFiles removed — what was lost?\nModified files — what specifically changed? Which lines?\n\nStep 3: Analyse changes in context.\n\nThis is the critical part. You must understand WHY each change exists based on what the skill does. Only report changes you can actually explain.\n\nAsk yourself for each change:\n\nDoes this change make sense given what the skill does?\nDoes a new URL/endpoint point to the expected service? (e.g., Xcellent adding a new api.x.com endpoint = expected. Xcellent adding a call to evil-server.com = suspicious.)\nDo new credential references match the skill's domain? (e.g., a Spotify skill asking for $SPOTIFY_CLIENT_SECRET = expected. A Spotify skill asking for $OPENAI_API_KEY = suspicious.)\nDo new shell commands make sense for the skill's function?\n\nStep 4: Report to user with confidence.\n\nPresent changes in plain language. Group by significance:\n\nWhat changed — clear, specific summary (not a raw diff dump)\nWhy it likely changed — your contextual analysis\nAnything suspicious — ONLY flag things that genuinely don't belong. A Spotify skill updating its Spotify API calls is NOT suspicious. A Spotify skill adding a curl to an unrelated server IS suspicious.\n\nCRITICAL: Zero false positives. Do NOT flag normal, expected changes as suspicious. If a skill that manages X/Twitter adds a new X API endpoint, that is expected behaviour. If a DNS skill updates its blocklist URLs to known blocklist providers, that is expected. Use your understanding of the skill to distinguish normal updates from genuine anomalies.\n\nStep 5: Ask user to approve or reject.\n\nIf all changes look expected → \"Update available (v1.0.2 → v1.1.0): [summary]. Looks good — want me to update?\"\nIf something is genuinely suspicious → \"Update available but I found something unusual: [specific concern]. I'd recommend reviewing before updating.\"\nIf user approves → write the updated files from the API response and update _meta.json with the new version\nIf user rejects → proceed with the existing local version" }, { "title": "Example: Smart diff in action", "body": "User: \"Check my X analytics\" (Xcellent skill installed at v2.1.0)\n\nYou:\n1.

Group by significance:\n\nWhat changed — clear, specific summary (not a raw diff dump)\nWhy it likely changed — your contextual analysis\nAnything suspicious — ONLY flag things that genuinely don't belong. A Spotify skill updating its Spotify API calls is NOT suspicious. A Spotify skill adding a curl to an unrelated server IS suspicious.\n\nCRITICAL: Zero false positives. Do NOT flag normal, expected changes as suspicious. If a skill that manages X/Twitter adds a new X API endpoint, that is expected behaviour. If a DNS skill updates its blocklist URLs to known blocklist providers, that is expected. Use your understanding of the skill to distinguish normal updates from genuine anomalies.\n\nStep 5: Ask user to approve or reject.\n\nIf all changes look expected → \"Update available (v1.0.2 → v1.1.0): [summary]. Looks good — want me to update?\"\nIf something is genuinely suspicious → \"Update available but I found something unusual: [specific concern]. I'd recommend reviewing before updating.\"\nIf user approves → write the updated files from the API response and update _meta.json with the new version\nIf user rejects → proceed with the existing local version\nExample: Smart diff in action\nUser: \"Check my X analytics\" (Xcellent skill installed at v2.1.0)\n\nYou:\n1. Read skills/xcellent/_meta.json → version \"2.1.0\"\n2. Call: GET /api/skills/install?slug=xcellent&mode=diff&installed=2.1.0\n3. Response: upToDate: false, latestVersion: \"2.2.0\"\n4. Read LOCAL skills/xcellent/SKILL.md → understand: X growth tool, uses X API,\n expects $X_BEARER_TOKEN, calls api.x.com for analytics, posts tweets\n5. Compare files:\n - SKILL.md: Added section on \"Engagement Rate Tracking\"\n - scripts/analytics.sh: New endpoint call to api.x.com/2/tweets/search\n - scripts/analytics.sh: Updated rate limit handling (sleep 15 → sleep 16)\n6. Analysis: All changes relate to X/Twitter analytics. New endpoint is on\n api.x.com (expected). No new credentials requested. No unusual URLs.\n7. Tell user: \"Xcellent update (2.1.0 → 2.2.0): Adds engagement rate tracking\n with a new X API analytics endpoint, and tweaks rate limit timing. All\n changes are X API related — looks clean. Want me to update?\"\n\nChecking for LarryBrain skill updates\n\nThis skill (larrybrain) itself also gets updates. The install API returns an update field when your client version is outdated — this is checked via the &v= parameter. If an update is available, tell the user to run clawhub update larrybrain. Show the message from the update field.\n\nYou should also apply the same smart diff logic to LarryBrain skill updates when they arrive via ClawHub. Read the local skill.md, compare with the incoming update, understand what changed and why, and present it to the user before accepting.\n\nHow to Search and Install Skills\n\nWhen the user needs something:\n\nIdentify what they're asking for\nSearch: GET /api/skills/search?q=relevant+keywords&limit=5\nIf a good match is found, download it: GET /api/skills/install?slug=THE_SLUG&mode=files (with API key header for premium)\nParse the JSON response\nWrite all files from the files array to skills/{slug}/\nRead the SKILL.md and follow the setup instructions\nIf the API returns 403, tell the user they need a subscription\nExample flow\n\nUser: \"I want to download this YouTube video\"\n\nYou:\n\nSearch: GET /api/skills/search?q=youtube+download\nFind \"Video Downloader\" (slug: video-downloader)\nDownload the skill:\ncurl -s -H \"x-api-key: $LARRYBRAIN_API_KEY\" \"https://www.larrybrain.com/api/skills/install?slug=video-downloader&mode=files\"\n\nParse the JSON response\nWrite each file to skills/video-downloader/\nRead the SKILL.md — it says to use yt-dlp\nInstall yt-dlp if needed: pip install yt-dlp\nRun: yt-dlp -o \"%(title)s.%(ext)s\" \"URL\"\nDone — the user gets their video\n\nCRITICAL: You must actually execute the skill instructions. Don't just read them and summarize. Don't create empty folders. Don't skip steps. Follow every instruction in the SKILL.md as if it were your own skill.\n\nLinking to skill pages\n\nWhen presenting skills to the user, include a link to the skill's page:\n\nhttps://www.larrybrain.com/skills/{slug}\n\nFor example:\n\nhttps://www.larrybrain.com/skills/xcellent\nhttps://www.larrybrain.com/skills/larry-marketing\nhttps://www.larrybrain.com/skills/video-downloader\nPresenting Available Skills\n\nWhen the user asks what's available or wants to browse:\n\nSearch with empty query or by category: GET /api/skills/search?category=home&limit=20\nPresent skills with icon, name, and one-line description\nMention which are free vs premium\nAsk if they want to use any of them\nMaking and Publishing Your Own Skills\n\nBuild something great and publish it to LarryBrain for others to use. Earn 50% revenue share.\n\nAnyone can create and publish skills:\n\nMust have active subscription + GitHub connected\nBuild your skill locally (SKILL.md + any supporting scripts/assets)\nCollect skill files, base64-encode content\nPOST to /api/skills/upload with API key, categories, icon, files\nAutomated security scan runs\nHuman review before approval\nPublished skills appear in search results\n\nVisit https://www.larrybrain.com/creators for the full creator guide.\n\nCategories\nmarketing, analytics, automation, dev-tools, writing, design\nproductivity, finance, communication, data, media, security\neducation, fun, home\nCredential Security\n\nSkills may reference API keys, tokens, or passwords (e.g. $SPOTIFY_CLIENT_ID, $HA_TOKEN). These are always:\n\nStored locally on the user's machine as environment variables\nUsed directly by the agent to call third-party APIs\nNEVER sent to LarryBrain's servers\n\nLarryBrain only serves skill files. We never see, proxy, or store user credentials. The agent talks directly to Spotify, Home Assistant, Gmail, etc.\n\nWhen a skill requires credentials, guide the user through getting their own API key from the third-party service and storing it locally.\n\nTransparency\n\nAll skill content is fully visible to users. You can show the user what a skill does if they ask. There is nothing hidden. Skills are downloaded to the user's machine and they can inspect every file.\n\nAffiliate Program\n\nLarryBrain has a 50% revenue share affiliate program. When a user asks about becoming an affiliate, earning money by referring others, or wants their referral link:\n\nDirect them to the affiliate signup: https://partners.dub.co/larry-brain\nThey sign up, fill in name/email/country, and get auto-approved\nThey receive a unique link like larrybrain.com/{their-name}\nWhen someone signs up and pays through that link, they earn 50% commission forever (as long as the subscription renews)\nPayouts are handled through Dub Partners (connects to their bank via Stripe)\n\nIf the user asks \"how do I earn money with LarryBrain\" or \"can I refer people\", always share the affiliate link.\n\nDocumentation\n\nFull documentation is available at: https://docs.larrybrain.com (or locally hosted at the docs page)\n\nKey reference for troubleshooting:\n\nCommon Issues with Outdated Client Versions\nUsing api.larrybrain.com — This domain doesn't exist. Correct base URL: https://www.larrybrain.com/api\nUsing Authorization: Bearer header — Wrong. Correct header: x-api-key\nMissing mode=files — Always include mode=files to get full skill files\nDRM wrapper in responses — Removed in v1.2.0+. If you see obfuscated content, run clawhub update larrybrain\nUsing content or longDescription field — Correct field is skillMdContent\nUsing larrybrain.com instead of www.larrybrain.com — Bare domain is intercepted by link tracking. Always use www.\nAPI Version Check\n\nInclude &v=1.5.3 in all install requests. If the response contains an update field, tell the user to run clawhub update larrybrain. The install still works — version check is informational only, never blocking.\n\nConstraints\nAlways use mode=files when downloading skills\nAlways write files to skills/{slug}/ before executing\nAlways present the subscription prompt politely when access is denied\nDon't make up skills that don't exist in the library\nFree skills (Xcellent, Larry Marketing) are always accessible without auth\nWhen presenting skills, include the icon and whether it's free or premium\nRate limit: 60 requests per minute" }, "trust": { "sourceLabel": "tencent", "provenanceUrl": "https://clawhub.ai/OllieWazza/larrybrain", "publisherUrl": "https://clawhub.ai/OllieWazza/larrybrain", "owner": "OllieWazza", "version": "1.5.3", "license": null, "verificationStatus": "Indexed source record" }, "links": { "detailUrl": "https://openagent3.xyz/skills/larrybrain", "downloadUrl": "https://openagent3.xyz/downloads/larrybrain", "agentUrl": "https://openagent3.xyz/skills/larrybrain/agent", "manifestUrl": "https://openagent3.xyz/skills/larrybrain/agent.json", "briefUrl": "https://openagent3.xyz/skills/larrybrain/agent.md" } }
