- Cross-post blog content to social platforms. Crier is MCP-native with 17 tools. This skill provides judgment context that tools can't: rewrite guidelines, platform culture, workflow tips.
Crier Cross-Posting
Crier cross-posts blog content to multiple platforms. The blog is the source of truth.
Division of labor:
- Crier MCP tools handle mechanics: publish, track, query, validate
- Claude handles judgment: rewrites, platform voice, user interaction
Platform Reference
| Platform | Mode | Limit | Short-form? | Notes | |-----------|--------|--------|-------------|--------------------------------| | devto | API | none | No | Tags auto-sanitized | | hashnode | API | none | No | | | bluesky | API | 300 | Yes | Needs rewrite | | mastodon | API | 500 | Yes | Needs rewrite | | medium | import | none | No | User imports from canonical URL | | twitter | paste | 280 | Yes | Copy-paste only | | threads | paste | 500 | Yes | Copy-paste only | | linkedin | paste | none | No | Copy-paste only |
Rewrite Guidelines
When cross-posting to short-form platforms (bluesky, mastodon), write a rewrite
and pass it via crier_publish(rewrite_content=...).
Rules
- Lead with insight, not summary. Open with the most interesting idea.
- No meta-language. Don't say "New blog post" or "I wrote about."
- Crier appends the canonical URL automatically. Never include it in the rewrite.
- Match platform voice:
- Bluesky: conversational, personal, like talking to a friend
- Mastodon: slightly more formal, technical audience
- Stay under the limit. Bluesky 300 chars, Mastodon 500.
Anti-patterns
- "Check out my latest post on X" (meta)
- "In this article, I explore..." (academic tone for social)
- Including the URL in the rewrite text (crier adds it)
- Generic summaries that could describe any article
Good example
Article: "pagevault: Hiding an Encryption Platform Inside HTML" Bluesky rewrite: "What if a single HTML file could encrypt anything you drop into it? No backend, no JS libraries. Just the browser's Web Crypto API and some careful engineering."
Workflow
Quick publish (single file)
crier_check(file_path)to validatecrier_publish(file_path, platform, dry_run=True)to previewcrier_publish(file_path, platform, confirmation_token=...)to execute- For short-form: read the article, write rewrite, pass as
rewrite_content
Audit and bulk publish
crier_search(since="2w")to find recent contentcrier_missing(platforms=["devto","hashnode","bluesky","mastodon"])for gaps- For bulk work, dispatch the cross-poster agent
- For analysis, dispatch the auditor agent
Important rules
- DevTo sanitizes tags: no hyphens, max 4 tags, lowercase
- Medium is import-only: publish registers the URL, user must import manually
- Twitter/LinkedIn are paste-only: content goes to clipboard

development
VerifiedTrustedCommunity
Force a research-agent run to conclude. Launches the researcher in synthesis mode: it reads state.md and log.md, writes .research/synthesis.md with outcome, key findings, failed approaches, open questions, and recommendations, then exits. Use when current results are good enough or the agent is stalling.
