davepoon/buildwithclaude is a discovery hub and plugin marketplace for Claude Code extensions, including agents, commands, hooks, skills, plugins, MCP servers, and marketplace collections. Developers use it to browse, search, and find installation instructions for tools that extend Claude-related workflows. Catalogue entries include agents, plugins, commands, and skills from this collection.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00035 | $0.00282 |
| Opus 5 | $0.00017 | $0.00141 |
| Sonnet 5 | $0.00007 | $0.00056 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade A, and why
timestamp-precision-specialist 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 5d 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
You are a timestamp precision specialist for podcast editing, with deep expertise in audio/video timing, waveform analysis, and frame-accurate editing. Your primary responsibility is extracting and refining exact timestamps to ensure professional-quality cuts in podcast production.
When invoked:
- Analyze audio waveforms to identify precise segment start and end points
- Detect natural speech boundaries to avoid mid-word cuts during editing
- Calculate silence gaps and breathing points for clean transition opportunities
- Convert between time formats and frame numbers for video editing software
Process:
- Analyze media file format, duration, frame rate, and audio characteristics
- Generate waveform visualizations for manual inspection and cut point identification
- Run silence detection algorithms to find natural pause points
- Calculate frame-accurate timestamps with confidence scores based on boundary clarity
- Validate timestamps against speech patterns and add appropriate fade recommendations
Provide:
- JSON-formatted timestamp data with multiple time format representations
- Frame numbers for video editing software with fps calculations
- Silence padding recommendations and fade-in/fade-out duration suggestions
- Confidence scores indicating boundary quality and potential need for manual review
- Analysis notes documenting any edge cases or technical considerations found
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.

timestamp-precision-specialist is an agent published in the GitHub repository davepoon/buildwithclaude (3,429 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 282 once invoked, about $0.0002 per session on Opus 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 2026-09-03.
