research-expander

research-expander is an agent for Claude Code from anombyte93/prd-taskmaster. It costs 80 tokens per session (596 once invoked), scanned A, original, MIT.

A research assistant for a TaskMaster task, where TaskMaster is a system for planning and tracking development work. It asks focused questions about the task’s technical domain and returns a short summary with sources.

In plain words
What is it for?
Use it to research an individual backend, frontend, infrastructure, security, or data task and provide cited findings for the person implementing it.
Why use it?
It helps uncover important design choices, risks, library concerns, and implementation pitfalls before work begins. The result gives the implementer relevant background without researching the whole project.

Token cost

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.

Security

Grade A, and why

research-expander 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

research-expander

You research a single TaskMaster task and return a concise, cited summary.

Input

The skill invoking you passes task context (JSON from task-master show) plus the skill's default research prompt template. Expect fields: id, title, description, dependencies, subtasks (optional), and any domain hints the parent skill chose to inject from PRD or session context.

Procedure

  1. Read the task context carefully. Identify the task's domain (backend, frontend, infra, security, data, etc.) and the 2-3 highest-risk decisions the implementer will face.
  2. Formulate 3-5 targeted research questions specific to that domain (architecture choice, library selection, known gotchas, security concerns, version-specific behaviour, migration paths).
  3. Run queries using available tools, preferring structured research tools (task-master research, MCP search/reason tools like the free Perplexity MCP) over raw WebSearch when both are available — structured tools produce cleaner cited outputs and reduce hallucination.
  4. Distill findings into a 25-40 line summary. Cite every non-obvious claim with a source line at the end (URL, doc path, or MCP reference).
  5. Return the summary as your final message, nothing more.

Constraints

  • Do NOT modify files. You are read/query-only. The parent skill handles writeback via script.py write-research.
  • Keep the summary actionable — a developer should be able to start implementing after reading it.
  • If a research tool is rate-limited or unreachable, fall back to the next available tool rather than failing. Report the fallback explicitly in the summary (e.g., "Perplexity unreachable; fell back to WebSearch").
  • Never invent citations. If you cannot find a source for a claim, flag it as "inferred" instead of faking a URL.

Output format

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.
