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.

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 | $0.00046 | $0.03820 |
| Opus 5.5 | $0.00018 | $0.01528 |
| Sonnet 5.5 | $0.00009 | $0.00764 |
| Haiku 4.5 | $0.00005 | $0.00382 |
Grade A, and why
social-media-post scanned grade A with 0 findings 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 11d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Social Media Post Generator Skill
Generate platform-optimized social media posts using algorithm insights and best practices.
Note: This is a LOCAL skill for Navigator marketing only. NOT included in the plugin distribution.
When to Invoke
Auto-invoke when user says:
- "Create a Threads post about [topic]"
- "Write a social media post for [announcement]"
- "Generate X post for [feature]"
- "Create LinkedIn announcement for [release]"
- "Write Threads post like option 5"
What This Does
Platform-Specific Workflow:
- Analyze Content: Extract key points, features, value propositions
- Apply Platform Rules: Character limits, formatting, hashtag strategies
- Optimize for Algorithm: Engagement tactics, timing recommendations
- Generate Variants: Multiple options (short, medium, detailed)
- Include Metadata: Character count, hashtag suggestions, posting time
Platforms Supported: Threads, X (Twitter), LinkedIn
Platform Specifications
Threads (Instagram)
Character Limits:
- Standard post: 500 characters
- Long-form (with attachment): 10,000 characters
- Display: Shows "Read more" after ~500 chars
Formatting: ✅ Bold, italic, underline, strikethrough ✅ Emojis (count toward limit) ✅ Bullet points (using • or -) ✅ Line breaks ❌ No hashtags in Threads (algorithm ignores them) ❌ No clickable links in body (use link preview)
Media:
- Images: Up to 10 per post
- Video: Up to 5 minutes
- Link previews: Automatic from URLs
Algorithm Priorities (2025):
- Engagement (40%): Likes, comments, shares, reply views
- Recency (30%): Fresh content gets priority
- Interest/Relevance (20%): Based on user's past interactions
- Profile Visits (10%): Likelihood user will click profile
Best Practices: ✅ Conversational, authentic tone (not corporate) ✅ Ask open-ended questions ✅ Create discussions, not announcements ✅ Post consistently (1-3x daily) ✅ Use visuals (images/videos boost engagement) ✅ Respond to comments within 1 hour ❌ No direct cross-posts from Instagram/X ❌ Avoid promotional language ❌ No hashtags (they don't work on Threads)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

social-media-post is a skill published in the GitHub repository qf-studio/navigator (355 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 3,820 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-25.
Other skills, from other repositories
nav-install-multi-claude
DEPRECATED. The multi-Claude orchestration scripts are deprecated in favor of native Claude Code Workflows; no installation is needed. Auto-invokes on "install multi-Claude workflows", "set up multi-Claude", "enable parallel execution" to explain the deprecation.
nav-multi
DEPRECATED. Multi-Claude shell orchestration is superseded by native Claude Code Workflows. Auto-invokes on "run multi-agent workflow", "parallel agents for", "multi-claude for", "spawn agents for" to redirect the user to the native Workflow and Agent tools.
product-design
Automates design review, token extraction, component mapping, and implementation planning. Reduces design handoff from 6-10 hours to 5 minutes via direct Figma MCP integration. Auto-invoke when user mentions design review, Figma mockup, or design handoff.
social-media-post
Generate optimized social media posts for Threads, X (Twitter), and LinkedIn. Analyzes platform algorithms, applies best practices, and creates engaging content tailored to each platform. Local skill for Navigator marketing only.
nav-loop
Run tasks until complete with structured completion signals. Auto-invoke when user says "run until done", "keep going until complete", "iterate until finished", "loop mode", "autonomous mode".
nav-skill-creator
Analyze codebase patterns and create custom skills for repetitive workflows. Use when project needs automation or pattern enforcement. Auto-invoke when user says "create a skill for...", "automate this workflow", or "we keep doing X manually".
