A routing guide for Bloom, a canvas of live React frames backed by an application and database. It directs work to the appropriate Bloom instructions for coding, canvas work, or visual planning.

Use it when working with Bloom projects, its canvas pages, its MCP or command-line tools, or features that need visual planning and iteration.

It prevents confusion between Bloom's canvas frames and the project's code files, and requires checking access and project context before changes.

bloom — Skill for Claude Code by BloomLabsInc/agent-skills

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add BloomLabsInc/agent-skills --skill bloom

Clone the repo

git clone --depth 1 https://github.com/BloomLabsInc/agent-skills

Made for: Claude Code.

Or install bloom-agent-skills, the plugin that ships this one along with the rest of its 3 skills.

Per session 45 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 445 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00045	$0.00445
Opus 5.5	$0.00018	$0.00178
Sonnet 5.5	$0.00009	$0.00089
Haiku 4.5	$0.00005	$0.00044

Security

Grade A, and why

bloom 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 2mo 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

Bloom

Bloom is a canvas of live React frames backed by a full app (a sandbox codebase + Convex backend). You reach it through the Bloom MCP (or the bloom CLI). Two things are true and easy to get wrong:

Frames are not your repo. Canvas frames live at @bloom-frame/<uuid> and are React TSX rendered on the canvas. @/<path> is the Bloom project's sandbox, not the repo your editor has open.
You don't write the plan in prose — you build it as a frame. Designing and planning happen on the canvas.

Orient first

Before any read/write, ground yourself with three calls (details in bloom-mcp):

whoami — token works? what can it reach?
list_projects → list_branches → list_canvas_pages — pick the project, branch, and page you're working in.

If a step returns nothing or errors, stop and fix access before writing — don't guess IDs.

Which skill

Calling MCP tools (write_files, edit_files, code_search, trigger_agent, …) → bloom-mcp: the tool model, guardrails, and the full catalog.
Planning a feature or iterating on a design → bloom-visual-planning: build the plan as a canvas frame and iterate visually with the user.

Install these skills

Cross-agent (Claude Code, Cursor, Codex, …). The bloom CLI runs this for you on bloom init.

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.

bloom is a skill published in the GitHub repository BloomLabsInc/agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 445 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
