claude-tap is a local proxy and trace viewer for AI coding agents, recording and displaying their API requests, prompts, tool calls, responses, context, and token usage. It helps developers inspect and compare agent runs from tools such as Claude Code, Codex CLI, Gemini CLI, Cursor CLI, and others, while the catalogue skills and instruction support work with the project.

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 | $0.00029 | $0.00610 |
| Opus 5.5 | $0.00012 | $0.00244 |
| Sonnet 5.5 | $0.00006 | $0.00122 |
| Haiku 4.5 | $0.00003 | $0.00061 |
Grade A, and why
demo-video 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: Demo Video Generation
Generate demo assets from a real tmux E2E run and viewer screenshots.
Proven Workflow
1) Record terminal session in tmux with asciinema
tmux new-session -d -s demo -x 160 -y 46
tmux send-keys -t demo "asciinema rec /tmp/claude-tap-recordings/demo.cast" Enter
tmux send-keys -t demo "cd /path/to/claude-tap && scripts/run_real_e2e_tmux.sh" Enter
# ... wait until run finishes ...
tmux send-keys -t demo "exit" Enter
Notes:
Enteris the submit key for Claude Code TUI in tmux.- Use tool-triggering first prompt text so trace includes
tool_use.
2) Convert .cast to GIF with agg
agg /tmp/claude-tap-recordings/demo.cast /tmp/claude-tap-recordings/demo.gif
3) Convert GIF to MP4 with ffmpeg
ffmpeg -y -i /tmp/claude-tap-recordings/demo.gif -movflags +faststart -pix_fmt yuv420p .agents/recordings/demo.mp4
Browser Screenshots (HTML Viewer)
Use Playwright CDP to attach to a running Chrome/Chromium instance on port 9222.
browser = playwright.chromium.connect_over_cdp("http://127.0.0.1:9222")
page = browser.contexts[0].pages[0]
Reliable UI interactions
- Click entries by visible text content, for example:
page.query_selector('text="轮次 22"').click()
- Open diff view by clicking button text:
page.query_selector('text="对比上次"').click()
- For SPA/overflow layouts, scroll actual scrollable containers (not
window):
page.evaluate("""
() => {
for (const el of document.querySelectorAll('*')) {
if (el.scrollHeight > el.clientHeight) {
el.scrollTop += 300;
}
}
}
""")
Output Targets
docs/demo.gif.agents/recordings/demo.mp4- Optional localized variants (
docs/demo_zh.gif,.agents/recordings/demo_zh.mp4)
Avoid
- Do not reference non-existent scripts such as
cast_to_gif_ultra.pyormake_final_demo_v2.py. - Do not hardcode selectors like
.detailunless verified in the current viewer build.
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.
- 1mo ago First seen · 87 lines · 29 tokens per session scan A fe85bc9245ef
demo-video is a skill published in the GitHub repository liaohch3/claude-tap (3,311 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 610 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.
Other skills, from other repositories
browser-use
Direct browser control via CDP for web interaction: automation, scraping, testing, screenshots, and site/app work. Also covers hosted cloud browsers for AI agents: the browser-use Python library (Browser(usecloud=True)), Playwright, Puppeteer or any CDP client.
open-source
Documentation reference for writing Python code using the browser-use open-source library. Use this skill whenever the user needs help with Agent, Browser, or Tools configuration, is writing code that imports from browseruse, asks about @sandbox deployment, supported LLM models, Actor API, custom tools, lifecycle…
crit-story
Author a crit story and continue the interactive review loop only when the user explicitly invokes crit-story or directly asks you to generate a crit story. Do not infer this skill from generic review, PR, or diff-review requests.
lynkr
Universal LLM gateway with intelligent routing, Graphify code intelligence, Distill compression, routing telemetry, Code Mode, and 12+ provider support. 60-80% cost reduction for Claude Code, Cursor, and Codex.
snip
You are an expert at writing declarative YAML filters for snip, a CLI proxy that reduces LLM token consumption by filtering shell output.
goai
GoAI is a Go SDK for AI applications. One unified API across 25+ LLM providers. Inspired by the Vercel AI SDK, adapted to Go idioms (generics, interfaces, channels).
