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.

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 | $0.00053 | $0.00701 |
| Opus 5 | $0.00026 | $0.00351 |
| Sonnet 5 | $0.00011 | $0.00140 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
markstream-angular 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 2d 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.

Markstream Angular
Use this skill when the host app is Angular and the task is to adopt the Angular package cleanly.
Workflow
- Confirm the repo is Angular 20 or newer and accepts an alpha renderer API.
- Install
markstream-angularplus only the requested optional peers. - Import
markstream-angular/index.cssfrom the app shell.- Add
katex/dist/katex.min.csswhen math is enabled.
- Add
- Prefer standalone Angular integration.
- Use
MarkstreamAngularComponentinimportsand keep examples signal-friendly.
- Use
- Start with
[content].- For streaming AI chat, keep
[content]and use built-in smooth streaming first.[smoothStreaming]="'auto'"is the default and activates when[typewriter]="true"or[maxLiveNodes]="0".[typewriter]only controls the blinking cursor and defaults tofalse.[fade]controls node enter and streamed-text fade animations and defaults totrue.
- Streaming vs recovering history: in chat UIs the same component starts streaming and later switches to history when
[final]="true".- Streaming:
[smoothStreaming]="'auto'",[fade]="false",[typewriter]="true". Smooth pacing handles gradual appearance; fade would flicker. - Recovering history:
[smoothStreaming]="false",[fade]="true",[typewriter]="false". Content is already complete — pacing would slow it down, but fade gives a polished entry animation. - Dynamic switch:
[smoothStreaming]="isStreaming ? 'auto' : false",[fade]="!isStreaming".
- Streaming:
- Use
[final]for end-of-stream state; final parsing is gated until visible content catches up when smooth streaming is active. - Move to
nodes+finalonly for worker-preparsed content, shared AST stores, or custom AST control. - Remember that
[htmlPolicy]now defaults to'safe', and Mermaid strict mode is on by default through[mermaidProps].
- For streaming AI chat, keep
- Use
[customHtmlTags]and[customComponents]for trusted tag workflows. - Validate with the smallest useful Angular dev or build command.
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.

markstream-angular is a skill published in the GitHub repository Simon-He95/markstream-vue (2,972 stars, last pushed 2d ago), licensed MIT. It adds 53 tokens to every session and 701 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.

nba
Read the live cycle state and return the single highest-leverage next best action, not a menu. Use when a project is between phases, the author asks what to do next, too many valid threads are open, or the work needs re-entry into frame, build, drive, re0-memo, hate, re0-work, or ship.
