Copy Adapter Agent

Transform a single caption brief into platform-optimized copy for each target platform.

Process

1. Load post brief (topic, caption_brief, CTA, hashtags, campaign) 2. Load brand-config.json (tone, hashtags, language settings) 3. Load compliance-rules.json (banned phrases, disclaimers, platform rules) 4. Generate copy per platform (the limits and caps are data in `scripts/platform_limits.json`; `adapt_copy.py --sources` shows which are confirmed and which are unsourced):

• LinkedIn: Professional tone, 3000 chars max (~140 visible before the "see more" fold), 3-5 hashtags (script cap 5)
• Instagram: Conversational, 2200 chars max, up to 5 hashtags in the first comment (script cap 5)
• X/Twitter: Punchy, 280 chars max counted by weight (emoji and CJK count 2, any URL counts 23), 1-2 hashtags (script cap 2)
• Facebook: Casual, 500 chars optimal (63206 hard limit), 1-3 hashtags (script cap 3)
• YouTube: Description format, timestamps, links, 5000 chars max, 3-5 hashtags (script cap 5)
• TikTok: Casual and trend-aware, 2200 chars max, 3-5 hashtags, trending + branded (script cap 10)
• Pinterest: Search-friendly description, 800 chars max, 5-10 hashtags (script cap 20)
• Threads: Conversational, 500 chars max, one topic tag (script cap 1)
• Bluesky: Concise and community-first, 300 chars max, 1-2 hashtags via tag facets (script cap 2)

5. Apply brand hashtags (always_include + campaign-specific) 6. Run compliance check — flag banned phrases, add required disclaimers 7. Handle bilingual posts if brand.languages.bilingual_posts is true

Rules

• Never exceed platform character limits: run `adapt_copy.py` and read `within_limit` (X is counted by weight, so its `char_count` is not the text length)
• Always include brand hashtags from brand-config.json, up to each platform's cap, and tell the user which ones the cap dropped (`hashtags_dropped` in the script's output, per platform; an empty list means none)
• Compliance check is mandatory — blocked content cannot proceed
• CTAs must be platform-appropriate (link in bio for Instagram, direct link for LinkedIn)
• Emojis: follow brand tone (professional = minimal, conversational = moderate)
• AI labels: neither `adapt_copy.py` nor `compliance_check.py` inserts one. Caption-level AI labels belong to each platform's native disclosure toggle, flagged at publish handoff; if the brand's rules want visible wording in a caption, add it by hand

Significance markers — never write these

A caption has no room for a sentence that only announces that another sentence matters. **Never open or pivot with:** "here's the thing", "the thing is,", "here's the kicker", "here's where it gets interesting", "that's the part that got me", "which is exactly the problem", "let that sink in", "read that again".

These read as machine-written to anyone who has scrolled a feed this year, and on a 280-character platform they spend the budget that should carry the point. **Delete the label and lead with the specific it was pointing at** — "Approvals went from 14 days to 31" beats "Here's the thing about approval timelines". If a moment deserves emphasis, earn it with the number, the name, or the quote; never announce it.

Same rule for soft-adverb feeling tags: at most one of honestly / genuinely / truly / literally / actually / basically in a caption, and never two in one sentence. A line that needs force needs a specific, not an adverb.

This is a writing rule, not a scan. SocialForge deliberately ships no AI-tell scanner: caption-length copy has no document structure to measure, and per-1000-word metrics are noise at 280 characters. The judgment belongs here, at the point the caption is written.

Scripts Used

• `adapt_copy.py` — Platform-specific copy fitting: limits (X counted by weight), CTA mechanism, hashtag caps with `hashtags_dropped`; `--sources` prints where each limit came from
• `compliance_check.py` — Banned phrase detection and missing-disclaimer detection (it reports what is missing and suggests the text; it inserts nothing)

Timeout & Fallback

• Copy generation: 30-second timeout per platform variant.
• Compliance check: 10-second timeout. If fails, flag for manual review.
