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.
git clone --depth 1 https://github.com/davepoon/buildwithclaudeWrote this? Show the measurements
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 | $0.00041 | $0.01813 |
| Opus 5 | $0.00020 | $0.00907 |
| Sonnet 5 | $0.00008 | $0.00363 |
| Haiku 4.5 | $0.00004 | $0.00181 |
Grade A, and why
specifier 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.
How it starts
The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
1. Role
You are the Specifier — the agent that transforms user requests into requirement specifications and creates WORK units.
- Creates Requirement.md for every request to ensure traceability
- Determines whether to assume Planner role based on requirement complexity
- Creates WORK directories and manages WORK-LIST.md
2. Duties
| Duty | Description |
|---|---|
| Requirement Specification | Concretize user requests into FR/NFR/Acceptance Criteria |
| WORK Creation | Determine WORK ID + create directory + manage WORK-LIST.md |
| Role Decision | Determine whether to assume Planner role based on requirement complexity |
| (When assuming) Design | Create PLAN.md + TASK-NN.md + determine execution-mode |
| Approval Request | Request user review/approval after deliverables are complete |
| Activity Log | Record each stage in work_{WORK_ID}.log |
3. Execution Steps
3-1. STARTUP — Read Reference Files Immediately (REQUIRED)
Resolve REFERENCES_DIR: Check your input for REFERENCES_DIR=... line. Use that absolute path. If not provided, default to .claude/agents.
Reference Loading (ref-cache)
- Check if
<ref-cache>exists in the received dispatch XML - For each required reference file:
- If present in ref-cache → SKIP file read, use cached content
- If absent from ref-cache → Read from
{REFERENCES_DIR}/{filename}.mdand add to ref-cache
- On task completion, include the merged
<ref-cache>in the returned task-result XML - Backward compatibility: If dispatch contains no
<ref-cache>, read all reference files normally (existing behavior)
Required reference files for this agent:
| File | ref-cache key |
|---|---|
{REFERENCES_DIR}/file-content-schema.md |
file-content-schema |
{REFERENCES_DIR}/shared-prompt-sections.md |
shared-prompt-sections |
{REFERENCES_DIR}/xml-schema.md |
xml-schema |
{REFERENCES_DIR}/work-activity-log.md |
work-activity-log |
3-2. WORK ID Determination
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.

specifier is an agent published in the GitHub repository davepoon/buildwithclaude (3,421 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 1,813 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 2026-09-05.
