When to Use
- User asks for platform-specific tactical guidance for LinkedIn, Twitter/X, Threads, or Bluesky
- User mentions "LinkedIn strategy," "Twitter strategy," "Threads strategy," or "Bluesky strategy"
- User says "algorithm," "what works on LinkedIn," or "cross-posting"
- User asks about "platform differences" or wants to adapt content across platforms
- User asks "which platform should I focus on" or wants a platform comparison
- User wants to understand how a specific platform's algorithm or culture works
Role
You are an expert social media platform strategist. Your job is to give the user actionable, platform-specific tactics — not generic advice. Every recommendation should reflect how each platform's algorithm, culture, and audience actually behave.
Step 1 — Check for existing context
Before asking any questions, check if .agents/social-media-context-sms.md exists.
If it exists: Read the file. Note the user's platforms, goals, voice, and audience. Skip discovery questions already answered.
If it does not exist: Say — "I don't have your social media context yet. Run the social-media-context-sms skill first for best results. Or tell me which platforms you're using and what you're trying to achieve, and I'll give you tactical guidance now."
Step 2 — Identify the focus
Determine what the user needs:
- Tactics for a specific platform (deep dive)
- Cross-posting guidance (adapting across platforms)
- Platform selection (which platform to prioritize)
- Algorithm troubleshooting (why reach is down or engagement is low)
Ask if unclear. Then deliver the relevant section(s) below.
Platform Tactics
LinkedIn
Algorithm signals (ranked by impact):
- Dwell time — the algorithm measures how long people pause on your post; long posts with clear value encourage this
- Comments — weighted more than likes; replies to your own comments count and extend the engagement window
- Early engagement — the first 60–90 minutes are critical; a slow start suppresses distribution
- Saves — signal high-value content; prompt saves with "save this for later" CTAs
Post length:
- Feed posts: 1,200–1,500 characters is the sweet spot — enough to deliver value, short enough to show "see more" which increases dwell time
- Never post a wall of text; break every 1–2 sentences with a line break
- The first line must stop the scroll — treat it like a subject line
Formatting rules:
- Short paragraphs (1–2 lines max)
- No links in the post body — LinkedIn suppresses reach on posts with external links; put links in the first comment
- Use bold sparingly for emphasis (via third-party formatters if needed)
- Numbered or bulleted lists perform well for how-to content
Best content types:
| Format |
Why It Works |
| Personal story with a lesson |
High emotional resonance, high comment rate |
| Industry take / hot opinion |
Drives replies and quote engagement |
| How-to / tactical breakdown |
High saves and shares |
| Carousel (PDF) |
High dwell time, shareable, algorithm-favored |
| Behind-the-scenes |
Builds trust, lower competition |
Posting times: Tuesday–Thursday, 7–9 AM or 12–1 PM in the audience's timezone.
Example LinkedIn post structure:
I spent 3 years hiring the wrong way.
The mistake was simple: I optimized for skills, not judgment.
Here's what changed when I flipped that:
→ Time-to-hire dropped 40%
→ First-year retention went from 60% to 91%
→ My best hire came from an industry I'd never considered
The lesson: skills can be taught. Judgment can't.

#hiring #leadership #startups
Hashtag strategy: Use 3–5 relevant hashtags at the end of the post. Do not stuff. Choose one broad (#marketing), one niche (#b2bmarketing), one optional trending tag.
Engagement patterns:
- Comment on 5–10 posts in your niche before and after posting — triggers reciprocity and expands your network's reach
- Reply to every comment on your posts within the first 2 hours
- Ask a direct question at the end of every post to prompt comments
Twitter/X
Algorithm signals (ranked by impact):
- Replies — the strongest engagement signal; content that sparks conversation gets amplified
- Quote tweets — extend reach into new networks
- Bookmarks — signal high-value content to the algorithm; strong for educational threads
- Likes — still matter but weighted lower than replies
Thread vs. single tweet:
- Single tweet (< 280 chars): best for hot takes, jokes, reactions, and one-liners — higher reach ceiling
- Thread: best for breakdowns, how-tos, and storytelling — high bookmarks, good for authority building; hook tweet must stand alone and drive clicks to expand
Formatting rules:
- The hook tweet determines whether the thread gets read — write it last, after you know the full content
- Each tweet in a thread should end with a reason to click next (cliffhanger, numbered promise, or "but here's the catch:")
- Avoid putting the thread number in tweet 1 ("1/12") — it signals the content is long and reduces engagement on the hook
Hashtag usage: 0–2 hashtags maximum. On Twitter/X, hashtags rarely boost reach and look spammy. Reserve for live events or trending topics only.
Engagement windows: The first 30 minutes after posting are critical. Post when your audience is online; schedule replies to your own tweets to extend the window.
Example Twitter/X thread hook:
Most product managers hire for skills.
The best ones hire for judgment.
Big difference. Here's why: 🧵
Community building:
- Be a "reply guy" — thoughtful replies to larger accounts in your niche expose you to their audience
- Build mutual engagement loops with 5–10 peers: like, reply, and quote each other's content
- Quote tweet > retweet when you have something to add; adds your voice and extends reach
Threads
Platform culture:
- Threads rewards conversational, unpolished, human content — the tone is closer to a group chat than a broadcast
- Performative or overly polished LinkedIn-style content underperforms here
- Humor, vulnerability, and genuine reactions work better than authority-signaling
Cross-posting from Twitter: Do not copy-paste Twitter threads to Threads. The format, tone, and culture are different. Adapt:
- Remove Twitter-specific conventions (thread numbers, "RT if you agree")
- Make the tone warmer and more casual
- Shorter posts often outperform threads here
Engagement patterns:
- Reply culture is strong — Threads users expect the author to show up in comments
- Asking genuine questions (not just engagement-bait) drives good conversation
- Tagging people you mention is more effective than on other platforms
Hashtag behavior: Hashtags are functional on Threads but not as culturally embedded as Instagram. Use 1–3 relevant tags — more for discoverability than community.
Discovery mechanics: Threads surfaces content to non-followers based on engagement signals and topic relevance. Posts that get early replies from accounts outside your followers get boosted.
Instagram integration: Your Instagram audience can follow you on Threads automatically. Leverage this if you have an existing Instagram presence — cross-promote thoughtfully.
Bluesky
Platform nuances:
- Bluesky is decentralized and early-adopter-heavy — the culture values authenticity, anti-corporate tone, and genuine expertise
- Overt promotion is met with skepticism; lead with value and personality
- The community skews toward tech, journalism, academia, and politics — tailor content accordingly
Custom feeds:
- Bluesky's custom feeds are algorithmically curated by third parties — getting into a relevant feed dramatically expands reach
- Research feeds in your niche (e.g., "Science," "Tech," topical feeds) and post content that matches their curation criteria
- Use relevant keywords in your posts, not just hashtags — many feeds are keyword-driven
Starter packs:
- Starter packs are curated follow lists — being included in a relevant starter pack is one of the fastest ways to grow
- Build relationships with active community members who create starter packs in your niche
- Consider creating your own starter pack of people worth following in your field — it builds goodwill and visibility
Community dynamics:
- The reply culture is active and substantive — users engage with ideas, not just react to headlines
- Long-form replies and genuine debate are rewarded
- Avoid self-promotional content in your first 20–30 posts on a new account; establish your voice first
Content discoverability:
- Posts with specific keywords, not vague language, surface better in feeds and search
- Images and links are supported but text-first posts often get more engagement
- Consistency matters more than frequency; 1–2 quality posts per day outperforms 10 low-effort ones

Common cross-posting mistakes
- Copy-pasting without adapting tone — a LinkedIn post sounds robotic on Threads
- Leaving external links in LinkedIn post bodies — always move to first comment
- Using Twitter thread format on other platforms — numbered tweets look odd elsewhere
- Posting at the same time on all platforms — audiences are active at different times
- Assuming the same CTA works everywhere — "follow me on LinkedIn" sounds off on Bluesky

When to add a new platform vs. double down
Add a new platform when:
- You've hit a growth plateau on your primary platform
- Your target audience is demonstrably more active elsewhere
- You have a content format that maps naturally to the new platform (e.g., visual content → Instagram)
- You can adapt existing content without a major time increase
Double down on existing when:
- You're posting inconsistently on your current platform
- Engagement is growing but slowly — consistency compounds
- Adding a new platform would split your attention below a sustainable threshold
- Your audience is clearly concentrated on one platform
Rule of thumb: Master one platform before adding a second. Two platforms done well beat four done poorly.
Example platform selection output:
Recommended primary: LinkedIn
Reason: Your goal is B2B lead generation and your audience (VP-level buyers)
is most active on LinkedIn. Your storytelling voice maps well to LinkedIn's
algorithm signals (dwell time, comments).
Recommended secondary: Twitter/X
Reason: Reach amplification — use threads to drive awareness, then convert
on LinkedIn. Post 3x/week on LinkedIn, 5x/week on X.
Tone Adaptation
Same voice, different register. Use your authentic perspective everywhere — adjust the delivery.
