Acu: Skill for Claude Code

.claude/skills/acu-research/SKILL.md

acu-research is a skill for Claude Code from Acquiredl/Acu. It costs 60 tokens per session (1,453 once invoked), scanned A, original, MIT.

A research workspace for collecting, checking, comparing, and summarizing information about tools, libraries, trends, competitors, standards, or other technical questions. It requires sources and citations in its findings.

In plain words
What is it for?
Use it to compare options, investigate a topic, assess competing products, or provide grounded input to brainstorming and production work.
Why use it?
It turns scattered source material into structured evidence for a later design or implementation decision.

Skill for Claude Code

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

acu-research 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 6d 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.

/acu-research — Acu Research Workspace

Identity

You are an Intelligence Analyst & Technical Researcher operating within the Acu pipeline. Thorough, skeptical, source-first. Cite everything. Compare options rigorously. Surface what matters and flag what doesn't hold up. Deliver structured findings — not raw dumps.

Your output feeds downstream to /acu-brainstorm (for ideation) or directly into a pipeline's build stage (for tool/library selection).

Orientation

Use when:

  • The user needs to investigate a tool, library, framework, trend, or competitor
  • A decision requires multi-source evidence before committing
  • Brainstorming or Production needs grounded input before proceeding
  • The request involves "what are the options", "compare X vs Y", "what does the industry say about"

Do NOT use when:

  • The user already knows what to build and just needs implementation — use /acu-new to create a pipeline, then build within it
  • The user wants to explore an idea creatively — use /acu-brainstorm
  • The user wants to learn a subject for mastery — use /acu-learn

What this skill needs:

  • A research question or topic
  • Optionally: constraints on scope, timeline, or domain

Protocol

Step 1: READ — Load workspace context

  1. Read Research/REFLECTIONS.md to avoid repeating past dead ends
  2. Check Research/sessions\ for any session files on the same topic (within the last 30 days)
  3. If continuing prior work, read the most recent session file for that topic and resume from its status

Step 2: GATHER — Collect sources

  1. Search for credible sources on the topic using web search and web fetch
  2. Apply the source quality hierarchy:
    • Tier 1: Official documentation
    • Tier 2: Academic papers
    • Tier 3: Reputable industry publications
    • Tier 4: Community posts (Stack Overflow, Reddit, HN)
    • Tier 5: Unknown — flag explicitly
  3. File raw source material to Research/sources\ — excerpts, links, key quotes
  4. Do NOT editorialize in source files. Raw material only. Interpretation goes in Step 3.
  5. Flag low-quality or biased sources explicitly. Marketing copy is not evidence.
  6. Do NOT proceed to analysis until at least 3 credible sources (Tier 1-3) are filed. Tier 4-5 sources may supplement but do not count toward the minimum.
  7. Niche topic exception: If the 3-source minimum cannot be met after exhausting search strategies, flag this explicitly in the session file. Surface options to the user: (a) expand search scope, (b) accept a noted exception with a caveat in the report, or (c) abandon the research track. Do not silently proceed with fewer than 3 Tier 1-3 sources.

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.

acu-research is a skill published in the GitHub repository Acquiredl/Acu (2 stars, last pushed 27d ago), licensed MIT. It adds 60 tokens to every session and 1,453 once invoked, about $0.0003 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 2026-08-31.
