  • “/37-social-caption-global”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Read the brief and the brand voice
  2. Write the hook to funnel stage
  3. Write 2 genuinely different A/B variants
  4. Write the selection note
  5. Apply hashtags and platform adaptation

What it can do on your machine

Read from SKILL.md and the folder at commit 0360adc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

37 Social Caption Global loads about 2.2k tokens when it runs. Until then it costs about 184 tokens; SKILL.md has 916 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~184
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Social Caption (Global)

Organic captions for owned social posts on Instagram, LinkedIn, TikTok, Facebook, and X. A good caption has a hook strong enough to stop the thumb, a body that earns the scroll, and a CTA clear enough that the reader knows what to do. Written for someone reading on a phone, moving fast.

Not this skill: paid ad copy — different constraints (ad policy review, character limits in placements, primary text truncation, iteration against CPA). Use 05-ad-copy-global.

Information gathering

Read the Brand Voice Document (35-brand-voice-global) and the content brief (36-content-brief-global) first. If the brief already sets angle, hook direction, and CTA, use them — do not re-ask. If both are missing, ask up to 4 questions:

  1. What is the product, service, or topic — and is there a real number, testimonial, or case study available?
  2. Which funnel stage? TOFU (awareness) / MOFU (consideration) / BOFU (conversion)
  3. Which channel? Instagram / LinkedIn / TikTok / Facebook / X
  4. What is the intended CTA and target length? (comment / click / DM / book / buy — short under 100 words / medium 100-200 / long over 200)

Principles

  1. The first line is the hook. Never open with the brand name or a greeting. The reader decides in about a second.
  2. One caption = one message. Do not stack benefits into a single post.
  3. A specific number beats a vague adjective. "Cut onboarding from 11 days to 3" beats "dramatically faster".
  4. Write for mobile. Paragraphs of 1-3 sentences with white space between them. No walls of text.
  5. BOFU needs a clear CTA and a real reason to act now. Manufactured urgency is a brand risk; a genuine deadline, batch, or capacity limit is not.
  6. Read it aloud before you ship it. If it sounds like a status report, the tone is wrong.
  7. Check it against brand voice. Vocabulary and banned words from 35-brand-voice-global. Default banned list: "game-changer", "revolutionary", "unlock your potential", "don't miss out", "act now", "elevate your", "we're excited to announce", "best-in-class".
  8. Disclose material connections. Paid partnership, gifted product, affiliate link, or employee-authored posts need clear disclosure in the caption itself, not only in a platform tag — FTC endorsement rules apply to organic content.

Workflow

1. Read the brief and the brand voice

From 36-content-brief-global: angle, source insight, key message, CTA. From 35-brand-voice-global: tone, vocabulary, sentence rules. Without a brief, gather the 4 answers above first.

2. Write the hook to funnel stage

The hook must stand alone with no context.

StageHook directionTypical form
TOFUPain / curiosity / contrarianA question that names the frustration, or a statement that inverts the category's default belief
MOFUSocial proof / concrete resultA number, a short testimonial, a before-and-after
BOFUOffer / genuine urgencyA specific discount or bonus, a real deadline, a real capacity limit
3. Write 2 genuinely different A/B variants

The two variants must differ structurally, not by a few swapped words:

  • Variant A: one hook direction (for example pain) plus one body structure (for example a list).
  • Variant B: a different hook direction (for example curiosity or social proof) plus a different structure (for example a short narrative).

Each variant: Hook (opening line) then Body (2-4 short paragraphs, 1-3 sentences each) then CTA (a specific action).

Show full SKILL.md (383 more words)Show less
4. Write the selection note

State plainly: use A when [context or audience], use B when [context or audience], and how to mix (hook A with body B, or the reverse) if that is sensible.

5. Apply hashtags and platform adaptation

Hashtags are a discovery and categorization signal now, not a reach lever. Fewer and more targeted outperforms volume on every major platform.

ChannelHashtagsAdaptation
Instagram3-5, targeted to the actual topicThe first line carries the hook — it is what shows before "more". Visual leads; the caption supports it
LinkedIn3, professional and topicalFirst 2-3 lines are visible before "see more". First-person point of view, no hard sell, external links often better in the first comment
TikTok3-5, mixing one trending tag with niche tags1-2 lines, keyword-forward so it surfaces in TikTok search. The real hook lives in the first second of video; the caption supports it
Facebook0-2, or noneLonger captions work. Conversational. Line breaks matter more than hashtags
X1-2 maximumOne idea, no wind-up. If it needs more, it is a thread — write it as one

Truncation points and character limits change; check the platform preview before publishing rather than trusting a remembered number.

File name: social-caption-[topic]-[YYYYMMDD].md

markdown
# Social Caption — [Topic]

## Context
| Item | Detail |
|------|--------|
| Funnel stage | TOFU / MOFU / BOFU |
| Channel | |
| Objective | |
| Target length | |
| Source brief | [link to content brief if any] |
| Disclosure required | none / paid partnership / gifted / affiliate |

## Variant A — [hook direction]
**Hook:**
[Opening line — stands alone, creates pain / curiosity / surprise]

**Body:**
[2-4 short paragraphs, 1-3 sentences each, white space between]

**CTA:**
[Specific action]

## Variant B — [different hook direction]
**Hook:**
[Different angle — if A used pain, B uses curiosity or social proof]

**Body:**
[Different structure from A — if A used a list, B uses narrative]

**CTA:**
[May match or differ from A]

## Selection notes
- Use **A** when: [context / audience]
- Use **B** when: [context / audience]
- Mixing A+B: [hook A with body B or the reverse, if sensible]

## Hashtags
[Per platform norm — Instagram 3-5 / LinkedIn 3 / TikTok 3-5 / Facebook 0-2 / X 1-2]

## Brand voice check
- Matches Brand Voice Document: Yes / No
- Banned words: none present
- Read aloud: sounds natural
- Every claim substantiable: Yes
  • 35-brand-voice-global: read before writing (tone, vocabulary, banned words); run its section VII checklist before handoff.
  • 36-content-brief-global: supplies angle, source insight, key message, and CTA.
  • 01-content-calendar-global: captions are written against a calendar slot (channel, funnel stage, pillar).
  • 05-ad-copy-global: when the post will run as a paid ad, rewrite to ad-copy standards. Never push an organic caption into an ad unchanged.
  • 42-image-brief-global, 43-carousel-brief-global: the accompanying visual brief, produced after the caption is approved.

Quality checklist

  • First line is a hook — no brand name, no greeting.
  • One caption = one message = one CTA.
  • The two variants differ genuinely (different hook direction and different structure).
  • Selection note states when to use A and when to use B.
  • Specific numbers replace vague adjectives wherever evidence exists.
  • Paragraphs are 1-3 sentences and readable on a phone.
  • BOFU has a clear CTA and, where urgency is used, a real reason for it.
  • No banned words (checked against 35-brand-voice-global).
  • Hashtag count and style match the channel's current norm.
  • Material connection disclosed in-caption where one exists.
  • Read aloud — it sounds like a person talking.
