What is slack-gif-creation?

A guide for planning small animated GIFs for Slack, the workplace messaging platform, and preparing them as local media or artifact drafts.

Use it for team reactions, celebrations, onboarding animations, and other work-appropriate Slack GIF concepts or drafts.

It helps define an appropriate concept, audience, size, accessibility, and licensing before an animation is shared.

Token cost

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	$0.00030	$0.00438
Opus 5.5	$0.00012	$0.00175
Sonnet 5.5	$0.00006	$0.00088
Haiku 4.5	$0.00003	$0.00044

Security

Grade A, and why

slack-gif-creation 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 1mo 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.

What it actually says

Slack GIF Creation

Purpose

Support small, tasteful animated assets for Slack or team communication. Current execution should use native artifact/code paths or drafts unless a GIF encoder tool is implemented.

When To Use

Use for celebratory GIF concepts, team reactions, onboarding animations, or Slack-optimized media drafts.

Inputs And Evidence

Message intent, audience, brand/style, duration, dimensions, and delivery channel.
Native media capability status.

Tool Map

web-artifact-builder
algorithmic-art
media_storyboard_create
media_storyboard_inspect
channel_message_prepare
message-approval-policy
tool_search

Workflow

Clarify emotion/message and audience.
Define safe, work-appropriate concept.
Use media_storyboard_create to create a local storyboard/contact-sheet artifact for the GIF concept, dimensions, scenes, palette, accessibility, and licensing constraints.
Use media_storyboard_inspect to verify the artifact and SVG path.
Prepare Slack message only after review.
Do not send/post without approval.

Native Implementation Boundaries

Do not import Anthropic Slack GIF creator code.
GIF generation must be Stram-owned or approved artifact workflow.
Slack delivery uses native channel tools.
The native storyboard tool creates Markdown/JSON/SVG planning artifacts; a binary GIF encoder remains a separate approved implementation.

Safety And Approval

Avoid embarrassing, offensive, or copyrighted material.
External/team posting requires approval.
Respect brand and workplace norms.

Verification

Artifact path proves generated media/prototype.
Prepared Slack outbox proves draft only.
State if the deliverable is a storyboard/contact sheet rather than a binary GIF.

Failure Modes

Claiming GIF output from a storyboard.
Posting without review.
Oversized or inaccessible animation.

Changes

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.
