How We Evaluated OpenClaw Emoji and Sticker Skills

OpenClaw's community skill registry has grown past 5,400 entries, but fewer than a dozen target emoji and sticker workflows specifically. For teams building messaging bots and social automations, that small cluster covers everything from generating sticker-ready artwork to delivering mood-matched reactions inside Telegram and Feishu.

We tested each skill against five criteria:

  • Output quality: Resolution, format support (WebP, TGS, GIF, PNG), and platform-ready sizing.
  • Platform coverage: Which messaging apps the skill targets directly.
  • Automation depth: Whether the skill handles end-to-end creation and delivery or just one step.
  • Setup complexity: How many dependencies, API keys, or external services are required.
  • Cost: Free vs. paid, and per-image pricing where applicable.

1. Emoji and Sticker Generation

The emoji-sticker-generation skill is the most comprehensive option for creating custom emoji and stickers from scratch. It uses each::sense AI to produce photo-to-cartoon conversions, expression packs from a single reference image, and animated sticker assets optimized for each target platform.

Strengths:

  • Pre-sized exports for Slack, Discord, WhatsApp, Telegram, iMessage, and Teams.
  • Animated output in GIF, WebP, and TGS formats.
  • Batch generation for full expression packs and brand mascot sets.
  • Consistent visual identity across channels from one reference photo.

Limitations:

  • Requires an each::sense API key for generation.
  • Per-image API costs add up for large sticker packs.

Best For: Teams building branded emoji sets or sticker packs that need to work across multiple messaging platforms simultaneously.

Pricing: Skill install is free. API usage billed through each::sense.

2. Telegram Stickers (tg-sticker-emoji-mood)

This skill automates sticker and emoji delivery inside Telegram conversations based on conversational mood. Rather than waiting for a user to request a sticker, the agent sends mood-matched stickers autonomously, roughly 40 to 60 percent of the time during active conversations.

Strengths:

  • Bulk import of existing Telegram sticker packs with a single CLI command.
  • Auto-tagging using a 100+ emoji-to-emotion mapping table.
  • Context-aware selection with randomized choices to avoid repetition.
  • Configurable frequency control (recommended 2 to 5 messages between stickers).
  • Usage analytics to track which stickers land well.

Limitations:

  • Telegram-only. No cross-platform sticker delivery.
  • Requires careful frequency tuning to avoid spammy behavior.

Best For: Telegram bot builders who want conversational sticker reactions that feel natural rather than scripted.

Pricing: Free.

3. emoji-reaction-automator

The emoji-reaction-automator analyzes incoming messages and suggests an appropriate emoji reaction based on sentiment classification. It groups input text into categories like positive, negative, funny, curious, excited, and neutral, then returns a recommended emoji with a confidence score that downstream workflows can act on.

The skill runs entirely locally with no external API calls, which makes it fast and free to operate at any volume. Agents in customer support, community moderation, or conversational workflows can tag messages with the right emoji in real time without adding latency from network round trips. For teams building on OpenClaw, this pairs naturally with the telegram-reaction-prober below to build end-to-end reaction pipelines.

Strengths:

  • No external dependencies or API costs.
  • Fast local classification across six sentiment categories.
  • Structured output for easy integration into downstream automation.
  • Extensible category mappings for custom tone adjustments.

Limitations:

  • Rule-based classification may miss sarcasm or mixed sentiment.
  • Six categories out of the box (expandable with custom mappings).

Best For: Support bots and conversational agents that need quick emoji tagging without external API overhead.

Pricing: Free.

4. Best Image Generation

While not emoji-specific, best-image-generation produces sticker-grade artwork through text-to-image generation, image-to-image style transfer, and in-place editing. It connects to an external image generation API and accepts common formats including JPEG, PNG, and WebP as inputs.

For sticker workflows, the text-to-image mode generates original artwork from prompt descriptions, while image-to-image mode converts photos or sketches into stylized sticker art. Teams pair this skill with the emoji-sticker-generation skill listed above for platform-specific formatting after initial creation. The combination covers the full pipeline from concept to platform-ready asset.

Strengths:

  • High-quality output suitable for sticker artwork and brand assets.
  • Multiple generation modes covering text-to-image, image-to-image, and editing.
  • Batch generation for producing multiple sticker designs in one run.

Limitations:

  • Requires an external API key with per-image costs.
  • Does not handle platform-specific sticker formatting (sizing, animated format conversion).

Best For: Generating original sticker artwork and concept art before formatting for specific platforms.

Pricing: Per-image API costs apply (typically under $0.25 per generation).

5. Feishu Sticker

Feishu Sticker delivers images as native stickers inside Feishu (Lark) conversations. It handles image upload, format conversion, and deduplication automatically, so agents can send stickers without manual preparation steps.

The skill offers three delivery modes: sending a specific image file, picking randomly from a configured sticker directory, or searching by emotional context. Searching by emotion finds and sends the closest matching sticker from the collection, which is useful for conversational agents that react to message tone in real time.

Strengths:

  • Native Feishu/Lark sticker delivery with automatic format handling.
  • Emotion-based and keyword-based sticker search.
  • Deduplication avoids uploading the same image twice.
  • Handles image compression for oversized files.

Limitations:

  • Feishu/Lark only. No cross-platform messaging support.
  • Requires Feishu API credentials.

Best For: Teams on Feishu or Lark who want automated sticker reactions in group chats and notifications.

Pricing: Free.

6. telegram-reaction-prober

Before an agent can react with a specific emoji in a Telegram chat, it needs to know which reactions that chat permits. Different Telegram groups and channels configure different sets of allowed reactions, and sending an unsupported one returns an error that breaks the workflow.

telegram-reaction-prober solves this by testing a curated list of candidate emojis against a target message and recording which ones the chat accepts. The results are saved per chat for reuse across agent sessions. When chat administrators change reaction settings, re-run the probe to keep the allowlist current. Pairing this with emoji-reaction-automator gives your agent end-to-end reaction coverage: detect sentiment, pick an emoji, and confirm the chat allows it before sending.

Strengths:

  • Maps allowed vs. blocked emoji reactions per Telegram chat.
  • Saves results for reuse across sessions without repeated probing.
  • Optionally cleans up test reactions after the scan.
  • Complements emoji-reaction-automator for end-to-end reaction workflows.

Limitations:

  • Utility tool, not a creation tool. It probes availability rather than generating content.
  • Works with a curated candidate set, not the full Unicode emoji range.

Best For: Telegram bot developers who need reliable emoji reaction delivery and want to avoid failed-reaction errors at runtime.

Pricing: Free.

7. Fastio MCP Server

Once your agents generate sticker packs and emoji sets, those assets need to live somewhere persistent and shareable. Fastio provides generous storage with 19 MCP tools that OpenClaw agents can access through Streamable HTTP at /mcp or legacy SSE at /sse.

Sticker workflows benefit from several specific capabilities. Branded sharing links let you distribute sticker packs to collaborators or clients without granting full workspace access. File versioning tracks iterations as you refine artwork. Intelligence Mode auto-indexes uploaded assets for semantic search, so agents can find the right sticker by describing what they need rather than browsing folders.

Alternatives like Google Drive or S3 handle basic storage, but they lack the MCP integration that lets OpenClaw agents read, write, and search assets directly. Local filesystem storage works for development but breaks when you need to share across agents or hand off to a human.

Strengths:

  • generous storage, no credit card required.
  • 19 MCP tools for agent-native file operations.
  • Built-in RAG via Intelligence Mode for semantic asset search.
  • Ownership transfer: agent builds the asset library, human takes over.
  • Branded sharing links for distributing sticker packs.

Limitations:

  • 50GB storage cap on the free tier.
  • Intelligence Mode queries consume monthly credits.

Best For: Teams that need persistent, shareable storage for generated sticker and emoji assets with full MCP access from OpenClaw.

Pricing: Business Trial (50GB, included credits, no credit card). Paid plans for higher storage.

How to Pick the Right Skill for Your Workflow

Start with emoji-sticker-generation if you need to produce original sticker packs from scratch, especially across multiple messaging platforms. For Telegram-specific workflows, pair tg-sticker-emoji-mood with telegram-reaction-prober to handle both sticker delivery and reaction compatibility. The emoji-reaction-automator adds sentiment-aware reactions to any chat platform without API costs.

If your sticker art needs higher quality or custom styles beyond what the emoji-specific skill offers, route through best-image-generation first and format the output afterward. Teams on Feishu or Lark should add the feishu-sticker skill for native sticker delivery in that ecosystem.

For asset management across all these workflows, Fastio's Business Trial gives your agents persistent storage, semantic search for finding the right sticker, and branded links for sharing finished packs. The sticker-analyzer skill (not covered in detail above) is also worth adding if you need to classify incoming images as stickers vs. screenshots vs. memes before processing them in your pipeline.
