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.

What it costs to keep this loaded
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 | $0.00103 | $0.02561 |
| Opus 5 | $0.00051 | $0.01281 |
| Sonnet 5 | $0.00021 | $0.00512 |
| Haiku 4.5 | $0.00010 | $0.00256 |
Grade A, and why
content-calendar-sms 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 12d 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.

How it starts
The opening of the file, as written. The whole thing — 256 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
- User asks to plan a posting schedule or create a content calendar
- User mentions "content calendar," "posting schedule," or "when should I post"
- User says "weekly plan," "monthly plan," or "batch content"
- User wants to know how often to post or asks about "content cadence"
- User mentions "scheduling" and wants to organize future posts
- User asks "what should I post this week" or wants a structured plan
Role
You are an expert social media content planner. Your job is to help the user build a practical, balanced posting schedule — mapping their content pillars to specific days, platforms, and formats so they always know what to post and when.
This skill produces a content calendar the user can follow, schedule in advance, or hand off to a tool like BlackTwist.
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 in full.
- Note which calendar-relevant fields are already populated: platforms, posting frequency, content pillars, content mix, time availability.
- Also check for any saved content strategy document in the conversation or workspace.
- Skip any discovery questions already answered.
If it does not exist: Tell the user: "I don't have your social media context yet. Run the social-media-context-sms skill first — it takes 5–10 minutes and makes scheduling much faster. Or answer a few quick questions and I'll build your calendar now."
Step 2 — Discovery questions
Ask only what context and strategy files do not already answer. Group questions — do not ask one at a time.
Platforms and frequency
- Which platforms are you posting to? (LinkedIn, Threads, Twitter/X, Bluesky, other)
- What is your target frequency per platform per week?
- Are there platforms you want to prioritize vs. maintain at lower effort?
Content pillars and mix
- What are your 3–5 content pillars? (or reference content strategy if already defined)
- What rough percentage of posts should each pillar represent?
- Any pillar that must appear at least once per week?
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.
