research-use-case

research-use-case is a skill for Claude Code, Codex from jeunessegamesee/clew. It costs 51 tokens per session (484 once invoked), scanned A, original, MIT.

A guided pass for researching how a service flow works and filling the next documented gap. It uses a coverage score and records the flow as Input → Branches → Output.

In plain words
What is it for?
Use it to map connections between services, investigate a named use case, update flow documentation in a monorepo (a repository containing multiple projects), and verify that the coverage score changes.
Why use it?
It prevents broad, repeated investigations by identifying one missing or incomplete part of the flow at a time and checking whether the documentation improved.

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-use-case 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 8d 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

Research use-case flows

This is one turn of the coverage loop. Measure is the skill; research is the actuator. See loop.md.

Read research.md, monorepo.md, score.md, tree.md.

  1. Redclew loop --root <repo>. If reflected, stop (or one P1). If empty, cartograph one service. If incomplete, the printed next P0 is the only gap this turn. clew score --root <repo> shows drift (spec/CBM/OTLP with no tree).
  2. Act — that neighborhood only (Input → Branches → Output). Smallest capture. Monorepo: update docs/flows.md edges.
  3. Greenclew loop --root <repo> again. Score or P0 count must move. If not, the write did not touch a scored hole — fix it before another gap.
  4. Hold — commit. Next session starts at step 1. Do not remap the platform. CI: clew score --fail-p0.

If this is a monorepo

Index hops (tree names + next only). Refresh docs/flows.md edges. The next P0 from the driver is the act target, not a survey of every service.

If this is one service

Same loop on that docs/hops.md.

Capture rules

  • Trees: Input → Branches → Output. Event can be a tree (dispatch).
  • One example JSON per path you actually saw.
  • Cite contracts. If the span died, stitch + log line.
  • Do not invent hops to look complete. Do not dump the monorepo into context.

Next session starts from the files you wrote. That is auto-research.

Changes

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.
