What is mobbin-capture?

A local reference library for saving and managing Mobbin screens, flows, website sections, notes, design decisions, and project context.

Use it to capture Mobbin examples, inspect saved references, update or remove them, and maintain durable design research for a project.

It keeps design references connected to a project so they can be reused, searched, exported, or shared later.

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	$0.00065	$0.01096
Opus 5	$0.00032	$0.00548
Sonnet 5	$0.00013	$0.00219
Haiku 4.5	$0.00006	$0.00110

Security

Grade A, and why

mobbin-capture 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/mobbin-capture.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mobbin Capture

Manage the local project artifact store that replaces the MCP capture tools.

Storage

Artifacts are saved under the active project identity in ~/.mobbin-mcp/projects/<project-id>/artifacts.json. Project detection uses git, MOBBIN_PROJECT_ROOT, PROJECT_ROOT, or the current directory.

Use:

node scripts/mobbin-capture.mjs <action> '<json>'

Actions

doctor: inspect auth, project detection, data paths, and artifact count
project-context: return detected project context
captures: return the current project's full captured artifact index as JSON
capture: save an artifact
capture-flow: search Mobbin flows and save the selected iOS, Android, or Web flow with ordered steps, hotspot metadata, screen URLs, source URLs, and optional visual hashes
capture-screen: search Mobbin screens and save the selected screen with patterns, elements, source URLs, and optional visual hash
capture-site-sections: fetch Mobbin site sections and save selected ordered Web sections with section images, page URLs, pattern metadata, video segment notes, and optional visual hashes
get: fetch one artifact by artifact_id
update: update fields on an artifact
delete: delete by artifact_id
search: search by query, tags, type, app_name, feature_area, limit
catalog: facet counts by type, tag, app, platform, pattern, element, feature area
export: export selected artifacts as json, markdown, prompt_pack, mem_palace_jsonl, or pr_markdown
import: import a JSON payload with merge_strategy append or replace
sync-shared-store: push, pull, or merge with MOBBIN_SHARED_STORE_DIR or shared_store_dir

Capture Fields

Required: type, title, summary.

Useful optional fields: tags, notes, app_name, platform, feature_area, journey_name, session_name, participants, implementation_hints, decisions, references, steps, source_urls, screen_url, flow_name, patterns, elements, related_artifact_ids, project_path.

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.
