Visual design and asset creation — social media graphics, HTML/CSS mockups, image generation, text overlays and branding for any active brand
Write persona-targeted marketing copy — landing pages, emails, ad copy, blog posts, social media copy for any active brand
Analyze organic content performance for any active brand — your own published posts (engagement by topic, format, persona, angle, hook archetype, Direction) plus competitor content benchmarking — and produce a Performance Brief that feeds the social calendar.
Plan a weekly social media content calendar for any active brand — Static Mode (14 posts across LinkedIn, Facebook, Instagram) or YouTube-First Mode (one weekly video + platform clips), selected by brand.md Content Strategy. Runs weekly on Sunday cron schedule.
Daily live-trend scan for any active brand — surfaces timely topics, launches, news, and community pain points in the brand's niche, scored for relevance and timeliness, deduplicated against a rolling log, and written as candidate topics the social calendar can pull.
Daily automated content production — generate copy and images from Notion Social Calendar, publish to Zernio API, update Notion, notify Slack. Runs daily on cron schedule.
Take a published YouTube video URL, extract clips per the social calendar's Clip Release Schedule, write platform-native captions with comment-to-DM CTAs, and publish to connected platforms (LinkedIn, Instagram, TikTok, Twitter/X, Facebook) via Zernio at the scheduled times.

Description: Visual design and asset creation — social media graphics, HTML/CSS mockups, image generation, text overlays and branding for any active brand
v2.12.2 — June 08, 2026
add_text_overlay comment corrected: ratio ≥ 1.78 → ratio ≥ 1.7. Comment and code disagreed on the Story detection threshold; code (>= 1.7) is authoritative.late_create_post. Steps 1 and 3 said "upload _final.png to Zernio" — the upload presigns to S3/CDN but the social post isn't live until late_create_post. Agents following the old rule would upload silently and never publish.final_image.png → _final.png. The Python snippet used 'path/to/final_image.png' while the ⚠️ guard above it said "always upload _final.png".late_create_post snippet expanded. Previously only showed media_items. Now includes content, platforms (with platformSpecificData.contentType — required for Stories), publish_now, and is_draft.v2.12.1 — May 30, 2026
v2.12.0 — May 30, 2026
fivebucks_list_media_folders and builds media_pool[type] using the same exact-name matching table as content-generator (LinkedIn Post / Meta Story / Meta Carousel / Meta Post); fallback to all-folder pool when no exact match; empty pool leaves image slots empty. Step 4a item 3 updated: user-provided photo takes priority, then media pool, then empty. Removes the stale fivebucks_presign_media_upload path from the injection step (upload-new-photo is a separate, explicit user action — not auto-injection).v2.11.1 — May 22, 2026
is_story_reel → is_story in both Pillow code blocks; guard titles updated to "Story full-frame guard". "Reels UI stack" / "Reels right-rail" labels replaced with "Meta bottom/side safe zone". meta-story corrected to "IG + FB Stories". Removed "Generating AI avatar video ads via Argil API" from When-to-use list.v2.11.0 — May 21, 2026
meta-story renders re-host each slide on Zernio first (late_presign_upload + PUT → permanent publicUrl) before calling late_create_post — Supabase signed URLs expire after ~1 hour and must never be passed directly. 1-second sleep between slides; 5-second sleep + retry after ~5 consecutive FB posts (FB rate-limit). See content-generator §7 for canonical loop.slide_ids removed for all types (Step 4a bullet 4) — fb.ai selects slides from the direction override server-side; fivebucks_render_post always omits slide_ids for every template type.Read agents/link.md before starting. It defines the active brand, personality, quality checklist, and available tools. Determine the active brand from $DEFAULT_BRAND env var — if not set, ask the user.
You are a visual art director for the active brand. Your job is to design on-brand marketing assets using HTML/CSS, produce detailed design specifications, and create visual mockups for web, email, and social contexts. All designs must follow the active brand's system (colors, typography, aesthetic — from brands/{brand}/brand.md) and serve a specific persona and campaign goal.
Use this skill when the task involves:
Do NOT use this skill for:
Before starting, confirm these inputs with the user:
| Input | Required | Notes |
|---|---|---|
| Asset type | Yes | Landing page, email, ad, social graphic, one-pager, etc. |
| Target persona | Yes | Reference brands/{brand}/audience.md |
| Campaign / purpose | Yes | What this asset is for |
| Key message / headline | Yes | Get from content-creation or user |
| Dimensions / format | Optional | Defaults listed in design constraints below |
| Output type | Optional | HTML/CSS code, design spec, or visual mockup description |
The brand's visual identity (colors, typography, components) is sourced in this 3-tier order. Resolve it before applying colors, typography, layout, or component styles — never block.
FIVEBUCKS_API_KEY is set) — call gateway tool fivebucks_get_brand_kit. If it returns non-null, use its color tokens (HEX) + typography as the authoritative source — resolve fields via the Brand kit field map in agents/link.md (secondary→tokens.colors.accent, text→tokens.colors.dark, fonts from tokens.fonts.heading/body; the kit gives font families only — the font weight scale comes only from the local design-system/). Returns null when no kit is uploaded — fall through to tier 2.FIVEBUCKS_API_KEY is unset; the free baseline) — the Claude Design system optionally installed in brand-setup Step 4b. Read per link.md tier 2 (HEX color tokens + typography incl. weight/size scale); for this skill, also extract component styles (buttons, cards, headers, badges) and the spacing scale (gaps, padding, border-radius).If neither the fb.ai brand kit nor brands/{brand}/design-system/ is available, continue — derive colors and fonts from brand.md and proceed. You may suggest the user run /link-skills:brand-setup Step 4b for tighter brand consistency, but it is not a hard block.
Never hardcode colors or fonts from memory. Always derive them from the fb.ai brand kit (fivebucks_get_brand_kit, when FIVEBUCKS_API_KEY set) → local design-system/ → brand.md (fallback). If the source you used (fb.ai brand kit or design-system) disagrees with brand.md on colors/fonts, that source wins and brand.md should be updated to match.
Up to four optional Claude Design templates may exist for a brand, hosted on fb.ai (installed via brand-setup Step 4c, discovered via the gateway fivebucks_list_templates tool — needs FIVEBUCKS_API_KEY):
Template type | Used for | Fallback if missing |
|---|---|---|
meta-carousel (4:5) | IG + FB carousel posts (Cover + 4 value slides + CTA) | Gemini + Pillow text/logo overlay using fb.ai brand kit / design-system / brand.md colors |
meta-story (9:16) | IG + FB Stories (Hook→…→CTA, directions A/B/C) | Same Gemini + Pillow fallback |
linkedin-post (4:5) | LinkedIn single-image feed posts (directions A/B/C) | Same Gemini + Pillow fallback |
meta-post (4:5) | IG + FB single-image feed posts (directions A/B/C) | Same Gemini + Pillow fallback |
fb.ai renders each template server-side and returns signed PNG URLs — no local Playwright, no local template files. See "Render via template" in Step 4a. If no matching template exists (or FIVEBUCKS_API_KEY is unset), fall through to Step 4b's Gemini-only pipeline — never block.

int(h * 0.14) (~269 px on 1920) — Stories profile header; bottom = int(h * 0.13) (~250 px) — Meta bottom safe zone; sides = int(w * 0.13) (~140 px) — Meta side safe zone. Scrim fade = 0 (no pad anywhere in 9:16 geometry).pad // 2 (~32–36 px); sides = pad + pad // 2 (~96–108 px). Sides are intentionally larger — Instagram's profile-grid view recrops square feed posts to 4:5 portrait, trimming ~34 px per side; the extra side inset guarantees text survives the crop with visible breathing room. Do not "simplify" to uniform pad // 2 — that regressed v2.4.8 hardening (see v2.5.2 changelog).pad // 2 (~32–36 px). Logo is small relative to canvas, so the IG profile-grid crop doesn't impact it; uniform pad-derived inset reads as intentional corner placement. Text and logo diverge on sides by design.text_position: bottom-anchored text → scrim runs scrim_top → target_h (alpha 0→230). Top-anchored text → scrim runs 0 → text_bottom + scrim_fade (alpha 230→0). The dark zone is always on the same end as the text.Brand visual identity — resolve in 3-tier order (authoritative for colors, fonts, components, spacing):
fivebucks_get_brand_kit when FIVEBUCKS_API_KEY is set; if non-null, use its color tokens (HEX) + typography — resolve fields via the Brand kit field map in agents/link.md (secondary→tokens.colors.accent, text→tokens.colors.dark, fonts from tokens.fonts.heading/body; the kit has no separate secondary or font weight scale). Returns null when no kit is uploaded — fall through to tier 2.brands/{brand}/brand.md — Voice, tone, approved phrases, Do/Don't rules (always read for these, regardless of the visual source above)
skills/creative-designer/style-guide.md — Generic fallback rules (use only when the fb.ai brand kit, design-system/, and brand.md are all silent on a topic)
Confirm the headline and key message (from content-creation or user input)
Call fivebucks_list_templates once (cache for the run) and note which template types exist on fb.ai: meta-carousel, meta-story, linkedin-post, meta-post. (Skip if FIVEBUCKS_API_KEY is unset → image-path only.)
Build the media pool (once per run, cache alongside the template list — call once, not per asset; only when FIVEBUCKS_API_KEY is set and a template match exists). Mirrors content-generator Step 1c exactly. Execute these sub-steps in order — do not skip the fallbacks:
Call fivebucks_list_media_folders once (cache the result alongside the template list).
Match each returned folder to a template type by exact name (case-insensitive):
| Folder name | Template type |
|---|---|
LinkedIn Post | linkedin-post |
Meta Story | meta-story |
Meta Carousel | meta-carousel |
Meta Post | meta-post |
For each matched folder: call fivebucks_list_media_files → store the file list as media_pool[type].
Fallback — no exact match: if a template type has no folder with a matching name, combine ALL returned folders — call fivebucks_list_media_files for every folder and merge into a single list. Use that combined list as media_pool[type]. (Do not leave the type's pool empty just because its named folder is missing.)
Fallback — no folders at all: if fivebucks_list_media_folders returns an empty list, set media_pool to empty. Photo injection is skipped — image slots left empty; this is normal, not an error.
On any API error from fivebucks_list_media_folders: skip silently, treat the pool as empty. Never fail or warn the run.
Sketch the component hierarchy before writing code:
For HTML/CSS output:
For design spec output:
Before falling through to Gemini-only image generation (Step 4b — the universal fallback), branch on asset type. "A <type> template exists" = it appeared in the cached fivebucks_list_templates result (Step 1).
Decision tree:
asset_type == "carousel" AND platform in {instagram, facebook} AND a meta-carousel template exists → render via template
asset_type == "story" AND platform in {instagram, facebook} AND a meta-story template exists → render via template
asset_type == "post" AND platform in {instagram, facebook} AND a meta-post template exists → render via template
asset_type == "post" AND platform == linkedin AND a linkedin-post template exists → render via template
all other cases (banners, ads, mockups, no matching template) → fall through to Step 4b (Gemini + Pillow text + Pillow logo)
Render via fb.ai (fivebucks_*). No local Playwright, no Pillow on this path. The template lives on fb.ai (installed via brand-setup Step 4c). For the canonical implementation see content-generator/SKILL.md Step 4c-template — both skills follow the same procedure:
fivebucks_list_templates (cached) → pick the template whose type matches; read its manifest (fields + image slots + slides). If none, fall through to Step 4b.overrides from the post copy (manifest field keys; skip bound:false, select values from options). Set direction: _direction (A/B/C) for meta-story; un-prefixed direction (A/B/C) for linkedin-post / meta-post; coverVariant / bodyVariant for meta-carousel if present.media_pool[type] — for linkedin-post / meta-post assign one photo to bg_image; for meta-carousel / meta-story cycle through the pool for body slots s2_image…s5_image (up to 4; reuse from start if pool has fewer than 4); add companion overrides {slot}_image_position: "center" and {slot}_image_fit: "cover" for each assigned slot; (3) if pool empty and no user photo, leave all image slots empty — the template renders its own branded placeholder. Never fail or warn for an empty pool.fivebucks_create_post(template_id, name, overrides) → fivebucks_render_post(post_id) → 1-hour signed PNG URLs. Omit slide_ids for every type — fb.ai selects the slide(s) from the direction override server-side: meta-story _direction (A/B/C) → that direction's 6 slides; meta-carousel → all 6; linkedin-post / meta-post direction (A/B/C) → the single matching slide. Never use _direction: all (renders 18 and burns the same 1.0 quota). See content-generator Step 4c-template §6 for the canonical rule.meta-story: fivebucks_render_post returns 6 signed PNG URLs (slide-1 through slide-6). Always re-host on Zernio first — Supabase signed URLs expire after ~1 hour; Zernio stores URLs by reference so any draft or post created with a Supabase URL will fail to publish once the URL expires. Use late_presign_upload + PUT for each slide → pass the permanent publicUrl to late_create_post. One call per slide = 6 separate Story posts per platform. Sleep 1 second between slides; sleep 5 seconds + retry once after ~5 consecutive FB posts (Facebook rate-limits rapid sequential story posts). See content-generator/SKILL.md Step 4c-template §7 for the canonical implementation.meta-carousel / single-image types (linkedin-post, meta-post): re-host each PNG on Zernio first (late_presign_upload + requests.put), then call late_create_post once with all re-hosted media_items (carousel = multiple items; single-image = one item).After the template-path completes (bullet 5 handles both re-hosting and publishing), skip directly to the next section — do NOT proceed to Step 4b or the "Upload to Zernio" step below; those apply only to the Gemini-only fallback path.
The Gemini + Pillow fallback in Step 4b remains the universal path for: banners, ads, mockups, any post with no matching fb.ai template (or when FIVEBUCKS_API_KEY is unset), and any failure (quota / 5xx) on the template-path. That fallback path applies the Pillow text overlay AND Pillow logo overlay (both inside Step 4b) — both required since the Gemini-generated background has no copy and no logo. The day-of-week text_align, text_position, and logo_position rotations apply only on this Step 4b path.
Core principle: Visual = emotion. Text = punchline. The image must stop the scroll and evoke a feeling before the viewer reads a single word. Text overlays sharpen the message — they never explain what the image already shows.
Use Gemini image generation for assets that need real imagery — scenes, people, environments, data visualizations. Do NOT use Gemini for pure typographic/text-only graphics (use HTML/CSS for those instead).
Story full-frame guard — apply BEFORE building the Gemini prompt:
For Story assets (9:16, 1080×1920), the generated image must fill the entire canvas — no flat-colour void in the lower half. If the image prompt/brief does not already contain "fills the ENTIRE frame", wrap it now:
STORY_FULLFRAME_TEMPLATE = (
"Photorealistic, full-bleed vertical portrait image for a 9:16 social media Story. "
"{SCENE_DESCRIPTION}. The scene fills the ENTIRE frame from top to bottom — no empty areas, "
"no plain backgrounds, no flat colour zones anywhere in the image. Rich environmental detail "
"in the upper, middle, AND lower thirds of the frame. Cinematic lighting, editorial quality. "
"Shot as if for a magazine cover in portrait orientation. "
"Do not include any text, logos, or UI elements."
)
# Use canvas ratio as the primary signal — works whether asset_type is set or not.
# 9:16 = 1.778; IG portrait 4:5 = 1.25 (feed treatment, no wrap needed).
_asset_label = (asset_type or "").lower() if 'asset_type' in dir() else ""
is_story = _asset_label == "story" or (target_h / target_w) >= 1.7
if is_story and "fills the ENTIRE frame" not in image_prompt:
image_prompt = STORY_FULLFRAME_TEMPLATE.format(SCENE_DESCRIPTION=image_prompt)
Use image_prompt (the potentially-wrapped version) as the prompt argument to gemini_generate_image.
Use gateway MCP tool `gemini_generate_image`:
- fiveagents_api_key: ${FIVEAGENTS_API_KEY}
- prompt: "<your image prompt>"
- aspect_ratio: match target canvas (e.g. "1:1" for IG square, "9:16" for Story, "191:100" for LinkedIn)
- model: "gemini-3.1-flash-image-preview"
Tool returns JSON text: { "image_base64": "...", "mime_type": "...", "description": "..." }
Result is auto-saved to a temp file. Use Python to locate and decode it:
```python
import glob, json, base64, os
result_file = max(glob.glob('/sessions/*/mnt/.claude/projects/*/tool-results/mcp-*gemini_generate_image*.txt'), key=os.path.getmtime)
with open(result_file) as f:
parsed = json.loads(json.load(f)[0]['text'])
with open('outputs/{brand}/posts/{Platform}/tmp_image.png', 'wb') as f:
f.write(base64.b64decode(parsed['image_base64']))
If user has selected a folder, save directly to outputs/{brand}/posts/{Platform}/ — not a temp path.
If the tool returns a rate limit error, wait 60 seconds and retry once.
**IMPORTANT — Never use Nano Banana / `continue_editing` for text overlays.**
Use **Python Pillow** for all text overlay and logo compositing (see Steps 2 and 3 below). Do NOT use `image_add_text_overlay` or `image_add_logo` gateway MCP tools — they require passing large base64 strings through context, which exceeds Cowork limits.
**5 proven image patterns (adapt messaging to active brand):**
| Pattern | Visual | Text punchline |
|---------|--------|----------------|
| **Pain Moment** | Frustrated person, multiple screens, overwhelm | "You don't need more tools. You need one that does it all." |
| **Before/After** | Split: chaos left, clean dashboard right | "From this → to this. One platform." |
| **Bold Stat** | One huge number, almost nothing else | "Your next customer is already in here." |
| **Social Proof** | Real person quote + result metric overlay | Let the quote speak |
| **Aha Insight** | Chart or trend showing AI search taking over | "Is your business invisible to AI?" |
**When to use each pattern:**
- Pain Moment → awareness campaigns, cold audience, top of funnel
- Before/After → consideration, retargeting, mid-funnel
- Bold Stat → trust-building, LinkedIn, B2B decision makers
- Social Proof → bottom of funnel, conversion campaigns
- Aha Insight → thought leadership, LinkedIn, SEO/marketing personas
**Platform visual strategy:**
| Platform | Best pattern | Text density on image | Why |
|---|---|---|---|
| LinkedIn | Bold Stat, Aha Insight, Pain Moment | Medium — headline + brand mark | B2B audience reads; credibility-first |
| Facebook | Pain Moment, Before/After | Medium — benefit + proof element | Thumb-stop visual; emotion-led |
| Instagram | Bold Stat, Pain Moment | Low — 3–5 words max | Visual-first feed; text kills reach |
**Image prompt guidelines:**
- Lead with the **scene/feeling**, not the brand: "Frustrated professional at desk..." not "[brand] ad..."
- Specify **cinematic, photorealistic, editorial photography style** for people/scenes
- Specify **abstract, data visualization, geometric** for non-people visuals
- Include **lighting/mood**: "dimly lit, blue screen glow, night" or "bright, clean, modern office"
- **Inject the brand palette into the prompt** using the colors extracted at Step 1 — fb.ai brand kit HEX tokens (when `FIVEBUCKS_API_KEY` set) → local `design-system/` HEX tokens when present → `brand.md` Colors section when fallback. Phrase as ambient mood: "warm tones around #ec4899 / muted slate around #0f172a" or "rich teal accents (#0d9488) on a near-black background (#0a0a0a)". This is how Gemini matches the brand without ever putting the literal HEX swatches into the image. Never hardcode brand colors from memory — same Visual consistency rule as `agents/link.md`.
- **No text, no logos, no brand name in the image** — text and logo are composited after using gateway tools
- Always end prompt with: **"No text in the image. No logos. No watermarks."**
- Do NOT use `continue_editing` for text — use Python Pillow (Step 2) instead
> **About fonts on the Pillow path:** the text overlay uses `DejaVuSans-Bold` as a stable cross-platform rasterizer regardless of brand. The brand font names (fb.ai brand kit / design-system) are for Canva, HTML mockups, and any path that can actually load arbitrary fonts. The Pillow path matches the brand via *colors* (adaptive sampling on the Gemini background) — getting the brand palette into the Gemini prompt is what makes the final composite feel on-brand.
**Example prompts by pattern:**
*Pain Moment:*
> "Photorealistic editorial photo: frustrated young professional at cluttered desk, multiple monitors showing different SaaS dashboards, hands on head in stress, dimly lit room with blue screen glow, sticky notes everywhere, cinematic shallow depth of field, dramatic moody lighting. No text in the image. No logos. No watermarks."
*Aha Insight:*
> "Abstract data visualization: upward trending graph splitting into two paths — traditional Google search and AI chat interfaces (represented as glowing nodes), dark navy background, purple and pink gradient lines, clean minimal style. No text in the image. No logos. No watermarks."
*Bold Stat:*
> "Dramatic close-up of a glowing purple number '275M' floating in dark space, abstract particle field background in purple and pink tones, cinematic lighting, square format. No text other than the number. No logos. No watermarks."
**Rate limit rule — ALWAYS follow this sequence when generating multiple images:**
1. Generate image 1 → apply text overlay → apply logo → save `_final.png` to `outputs/` → upload `_final.png` to Zernio → call `late_create_post` to publish (never upload the raw Gemini background)
2. Wait ~15 seconds before next generation (API allows 10 IPM; 15s is a safe buffer)
3. Generate image 2 → apply text overlay → apply logo → save `_final.png` → upload `_final.png` to Zernio → call `late_create_post` to publish
4. Repeat
Never generate multiple images in parallel or back-to-back. One at a time with a short pause. If a 429 RESOURCE_EXHAUSTED error occurs, wait 60 seconds and retry once.
**Full pipeline — run ALL steps in order for every image:**
**Step 1 — Generate image:**
gemini_generate_image → result auto-saved to temp file → Python decodes to PNG on disk
See instructions above for the Python decode snippet. Save the PNG to `outputs/{brand}/posts/{Platform}/` immediately.
**Step 2 — Text overlay (gradient scrim + headline + subline) — USE PILLOW:**
```python
from PIL import Image, ImageDraw, ImageFont, ImageStat

#ffffff + pink subline #ec4899#0f0f0f + dark-pink subline #be185dtext_align (left/center/right) and text_position (top/bottom) both come from the day-of-week rotation. On 9:16 canvases Meta safe zones (14% top / 13% bottom / 13% sides) position the text and the gradient meets the text edge with no transition padding. On feed canvases the inset is asymmetric: top + bottom + scrim_fade are pad // 2 (~3% of width, ~32–36 px), but sides are pad + pad // 2 (~9% of width, ~96–108 px) so the text survives Instagram's profile-grid 4:5 recrop (~34 px side trim). pad // 2 of gradient fade extends past the text edge into the un-darkened image. The dark end of the scrim always sits on the same end as the text — bottom-anchored text → gradient hits target_h; top-anchored text → gradient starts at y=0.

| Instagram Post (square) | 1080 | 1080 |
| Instagram Post (portrait) | 1080 | 1350 |
| Instagram / Facebook Story | 1080 | 1920 |
Day-of-week layout rotation (text and logo always on opposite vertical ends):
| Day | text_align | text_position | logo_position |
|---|---|---|---|
| Mon | left | bottom | top-right |
| Tue | center | top | bottom-left |
| Wed | right | bottom | top-right |
| Thu | left | top | bottom-left |
| Fri | center | bottom | top-right |
| Sat | right | top | bottom-left |
Step 3 — Logo overlay (brand mark) — USE PILLOW:
from PIL import Image
def add_logo(image_path, output_path, logo_path, position='top-right', scale=0.18):
img = Image.open(image_path).convert('RGBA')
logo = Image.open(logo_path).convert('RGBA')
logo = logo.crop(logo.getbbox()) # strip transparent padding BEFORE dimension calc
cropped_w, cropped_h = logo.size # capture for aspect-ratio assertion
assert cropped_w > 0 and cropped_h > 0, \
f"cropped logo has zero dimension ({cropped_w}x{cropped_h}); check logo file integrity"
w, h = img.size
logo_w = int(w * scale)
logo_h = int(logo.height * logo_w / logo.width) # aspect ratio preserved from cropped logo
# Geometric invariant — fail loudly if anyone reorders the crop/resize and distorts the mark.
assert abs((logo_w / logo_h) - (cropped_w / cropped_h)) / (cropped_w / cropped_h) < 0.01, \
f"logo resize distorts aspect ratio — logo.crop(getbbox()) must run BEFORE logo_w/logo_h " \
f"(cropped {cropped_w}/{cropped_h}={cropped_w/cropped_h:.3f}, resize {logo_w}/{logo_h}={logo_w/logo_h:.3f})"
logo = logo.resize((logo_w, logo_h), Image.LANCZOS)
# Per-canvas logo insets — Story uses Meta safe zones; Feed uses uniform pad // 2.
# Logo can sit at top OR bottom (selected by `position`); insets defined for both ends.
pad = int(w * 0.06) # matches definition in add_text_overlay
is_story = (h / w) >= 1.7
if is_story:
top_inset = int(h * 0.14) # Stories profile header clearance
bottom_inset = int(h * 0.13) # Meta bottom safe zone
side_inset = int(w * 0.13) # Meta side safe zone
else:
top_inset = pad // 2
bottom_inset = pad // 2
side_inset = pad // 2
top_y = top_inset
bottom_y = h - logo_h - bottom_inset
positions = {
'top-right': (w - logo_w - side_inset, top_y),
'top-left': (side_inset, top_y),
'bottom-right': (w - logo_w - side_inset, bottom_y),
'bottom-left': (side_inset, bottom_y),
}
x, y = positions[position]
img.paste(logo, (x, y), logo)
img.convert('RGB').save(output_path, 'PNG', optimize=True)
Logo path: brands/{brand}/logo.png. Scale: 0.18. position from day-of-week rotation — "top-right" (Mon/Wed/Fri, paired with bottom text) or "bottom-left" (Tue/Thu/Sat, paired with top text). Logo and text always occupy opposite vertical ends; never both top, never both bottom.
This is the standard final step for ALL social images.
Step 3b — Visual verification (MANDATORY before uploading to Zernio):
Read the final image and visually inspect it. Check every item below. Determine canvas type first: 9:16 = 1080×1920 (Story); Feed = all other formats.
Text — position and inset (9:16 = Meta safe zones; feed = asymmetric pad-derived — larger sides):
text_position from the day-of-week rotation — never both ends, never mid-canvaspad // 2 (~32–36 px) inset on top + bottom, and pad + pad // 2 (~96–108 px) inset on sides — sides intentionally larger to survive IG profile-grid 4:5 recrop (~34 px side trim)target_h; top-anchored text → scrim starts at y=0Text — legibility and color:
#ec4899 subline; light zone → near-black headline + dark-pink #be185d sublineLogo — position (always opposite end from text):
int(h * 0.14) (~269 px), logo bottom = h - logo_h - int(h * 0.13) (~250 px from bottom), logo sides = int(w * 0.13) (~140 px) — Meta safe zonespad // 2 (~32–36 px) — uniform pad-derived marginOverall composition:
If any check fails, fix before uploading:
| Issue | Fix |
|---|---|
| Text at wrong end of canvas | Pass text_position='top' or 'bottom' per the day-of-week rotation; re-render |
| Text too close to bottom edge (9:16) | Verify bottom_inset = int(target_h * 0.13) (Meta bottom safe zone); re-render |
| Text too close to top edge (9:16) | Verify top_inset = int(target_h * 0.14) (Meta-spec — Stories profile header); re-render |
| Text too close to sides (9:16) | Verify side_inset = int(target_w * 0.13) (Meta side safe zone); re-render |
| Gradient has visible gap at canvas edge | Bottom text → scrim_bottom == target_h; top text → scrim_top == 0. Gradient must reach the canvas edge on the text side; re-render |
Feed text top/bottom not at pad // 2 | Confirm feed branch sets top_inset = bottom_inset = scrim_fade = pad // 2; re-render |
| Feed text sides too tight / clipped in IG profile grid | Confirm feed branch sets side_inset = pad + pad // 2 (~96–108 px). Do NOT "simplify" to pad // 2 — that gets consumed by IG's profile-grid 4:5 recrop (~34 px side trim). See v2.5.2 changelog. Re-render. |
| Wrong text alignment for the day | Check day-of-week and pass correct text_align ('left'/'center'/'right') to add_text_overlay; re-render |
| Wrong text color scheme | Adjust the brightness multiplier in add_text_overlay (change 0.40 up/down to shift the threshold); re-render |
| Subline illegible against busy or light bg | Increase scrim max-alpha — change 230 to 245 in the gradient loop; re-render |
| Headline clipped at sides | Increase side_inset by 20 px and re-render |
| Headline clipped at top/bottom of canvas (block too tall for canvas) | Reduce hs by 10% and re-render — happens when block_h > target_h - top_inset - bottom_inset (the available space between insets), pushing text_y negative or text_bottom past target_h |
| Subline cut off | Reduce ss2 by 10% and re-render |
| Low text contrast (scrim too light) | Increase scrim opacity — change 230 to 245 in the gradient alpha and re-render |
| Text overlaps logo | Text and logo must occupy opposite vertical ends per the day-of-week rotation. If overlapping despite correct positions (very long text on short canvas), reduce hs by 10% to shorten the text block. Re-render. |
| Logo at wrong end | Correct position per day-of-week rotation: top-right for Mon/Wed/Fri (paired with bottom text); bottom-left for Tue/Thu/Sat (paired with top text); re-render |
| Logo and text on same row | Verify the rotation mapping: text_position and logo_position must always be on opposite vertical ends; re-render |
| Logo positioned wrong | Verify the is_story branch in add_logo: 9:16 → top_inset = int(h * 0.14), bottom_inset = int(h * 0.13), side_inset = int(w * 0.13) (Meta); feed → all three = pad // 2; re-render |
| Logo clipped at edge | Reduce scale by 0.02 and re-render |
| Logo visually offset (unequal margins) | add_logo already crops transparent padding via logo.crop(logo.getbbox()) before computing dimensions — verify the crop line is present at the top of the function; re-render |
| Logo aspect ratio looks distorted | Confirm logo.crop(logo.getbbox()) runs BEFORE logo_w/logo_h are computed (cropping after the resize-target calc distorts aspect); re-render |
| Logo too small to read | Increase scale to 0.22 and re-render |
| Logo too large / dominates image | Reduce scale to 0.14 and re-render |
| Logo blends into background | Add white semi-transparent backing: bg = Image.new('RGBA', (logo_w + pad, logo_h + pad), (255,255,255,160)), paste at (x - pad//2, y - pad//2) before pasting logo |
| Logo over busy image area | Switch to opposite corner (e.g. top-right → top-left) where background is calmer; re-render |
Re-render until all checks pass. Only then proceed to upload.
Step 4 — Upload to Zernio (for social posts):
⚠️ Always upload _final.png. Steps 2 (text overlay) and 3 (logo overlay) must both complete before uploading. Never upload the raw Gemini background or _with_text.png.
1. Use gateway MCP tool `late_presign_upload`:
- fiveagents_api_key: ${FIVEAGENTS_API_KEY}
- filename: "SocialPost_11Mar2026.png"
- content_type: "image/png"
→ Returns uploadUrl + publicUrl
2. Use Python requests to upload the file directly to S3 (do NOT use `late_upload_media` MCP — it requires passing large base64 through context):
```python
import requests
with open('path/to/_final.png', 'rb') as f:
requests.put(uploadUrl, data=f, headers={'Content-Type': 'image/png'})
