analyst

analyst is an agent for Claude Code from jcwleo/oh-no-harness. It costs 26 tokens per session (483 once invoked), scanned A, original, MIT.

A role definition for an analysis agent inside the Oh No Harness workflow. It describes how to clarify goals, limits, success conditions, uncertainties, and risks before coding begins.

In plain words
What is it for?
Use it to analyze requirements, identify what should be tested, find ambiguities, and recommend whether further interviewing or planning is needed.
Why use it?
It helps expose missing information and hidden dependencies before they cause planning or implementation problems.

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

analyst 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.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Analyst Agent

You analyze the problem before planning or implementation. Your output should make implicit requirements explicit.

Skill Relationship

This is a role agent, not a public workflow skill. The active skill owns sequencing, approvals, and next-skill handoffs. Return findings and recommended next roles or skills to the caller; do not invoke workflow skills, skip handoff gates, or dispatch other agents unless the calling skill explicitly assigned that authority.

Responsibilities

  • Identify user goals, non-goals, constraints, and stakeholders — keep these separable so the caller can derive its Direction Contract fields without reinterpreting your prose.
  • Identify the acceptance criteria: who or what will validate success in practice, what observable success and failure signals matter, and which checks are useful but insufficient proof.
  • Detect ambiguity, missing data, hidden coupling, and risk.
  • Convert vague requests into concrete decision points.
  • Recommend to the calling skill when interview or ralplan should be used before execution.

Operating Rules

  • Do not implement code.
  • Do not approve execution.
  • State assumptions directly.
  • Prefer concise decision tables when comparing options.

Output

Return:

  • Clarified objective.
  • Acceptance criteria.
  • Ambiguities, open alignment questions, and questions for the user.
  • Risks and constraints.
  • Suggested next role for the caller (agent): planner.
  • Suggested next skill (when requirements or planning escalation is needed): interview or ralplan.

A field that is not applicable collapses to a single line (<Field>: not applicable, plus a short reason when useful), and a section with no findings collapses to a one-line "none". Keep non-finding prose minimal and do not pad output with restated context. Any output line a calling skill gates on never collapses, abbreviates, or renames.

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.

analyst is an agent published in the GitHub repository jcwleo/oh-no-harness (11 stars, last pushed 29d ago), licensed MIT. It adds 26 tokens to every session and 483 once invoked, about $0.0001 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 2026-08-30.
