Sample Strands Agent with Amazon Bedrock AgentCore is an end-to-end reference architecture for building multi-agent chatbots on AWS. Teams use it to explore agent orchestration, tool execution, memory, browser automation, and agent-to-agent collaboration with Strands Agents and Bedrock AgentCore.
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.

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 | $0.00019 | $0.02880 |
| Opus 5.5 | $0.00008 | $0.01152 |
| Sonnet 5.5 | $0.00004 | $0.00576 |
| Haiku 4.5 | $0.00002 | $0.00288 |
Grade A, and why
excalidraw 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.
How it starts
The opening of the file, as written. The whole thing — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Excalidraw Diagrams
Create hand-drawn style diagrams, flowcharts, architecture diagrams, and mind maps using the Excalidraw format. Diagrams are rendered interactively in the Canvas panel.
When to Use This Skill
Use create_excalidraw_diagram when the user wants to visualize structure, flow, or relationships — not raw numbers.
| Use this skill for... | Use visualization skill for... |
|---|---|
| System architecture diagram | Sales figures by quarter |
| Flowchart or decision tree | Survey response percentages |
| Sequence / interaction diagram | Stock price over time |
| Mind map or concept map | Market share breakdown |
| Shapes, boxes, arrows, labels | Any x/y or segment/value data |
Diagram Type
Choose based on user intent. For Swimlane, Class, Sequence, ER, and DFD diagrams, read diagram-patterns.md before generating.
| Intent | Type | Pattern |
|---|---|---|
| Process steps, workflow, decisions | Flowchart | Rectangles + diamonds + arrows (see Example) |
| System components, dependencies | Architecture | Zone rectangles + boxes + arrows |
| Concept hierarchy, brainstorming | Mind Map | Center node + radial branch arrows |
| Entity connections, associations | Relationship | Boxes + labeled arrows |
| Cross-functional workflow, actor responsibilities | Swimlane | diagram-patterns.md |
| OOP class structure, inheritance | Class Diagram | diagram-patterns.md |
| Object interactions over time | Sequence Diagram | diagram-patterns.md |
| Database entities and relationships | ER Diagram | diagram-patterns.md |
| Data transformation, data movement | DFD | diagram-patterns.md |

Color Palette
Use these colors consistently across all diagrams.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

excalidraw is a skill published in the GitHub repository aws-samples/sample-strands-agent-with-agentcore (196 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 2,880 once invoked, about $0.0001 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 2026-08-30.

Create a DESIGN.md style baseline BEFORE building UI. Use FIRST when no design draft exists — installs a proven visual style, then invoke frontend-design to implement. For borrowing a known product style, getting consistent typography/colors/spacing, or needing a fast visual starting point.
sprinkles
Use this when the user wants a persistent UI panel — a dashboard, form, editor, report, or visualization that lives alongside the chat. Sprinkles are .shtml files under /shared/sprinkles/ rendered in the side rail or as a full-screen tab. For ephemeral inline widgets, use dips instead. Covers creation, modification…

dips
Use this whenever a response could benefit from richer visualization, guided interaction, or a touch of fun — pickers, calculators, sliders, mini explorers, charts, animated demos, choose-your-own-adventure prompts, anything that lands better as a hydrating widget than as plain prose. Dips are ephemeral shtml code…
