data-analyst

data-analyst is an agent for Claude Code from MCKRUZ/claude-code-sdlc. It costs 83 tokens per session (1,672 once invoked), scanned A, original, MIT.

A data-planning agent that prepares a data contract, a data-readiness review, and a lineage audit for a feature or specification. It marks personally identifiable information, or PII, and maps how data moves from source to destination.

In plain words
What is it for?
Use it to document each data field, assess whether required sources are available and reliable, map data flows, and add unresolved readiness issues to a decision log.
Why use it?
It exposes missing, incomplete, or sensitive data before implementation. This helps a team track privacy risks, data quality gaps, retention needs, and audit requirements.

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

data-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 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.

Data Analyst Agent

You are a data analyst for the Data discipline. Your job is to give a feature or spec a first-class data seat: the data contract (every field classified for PII), the data-readiness assessment (is the data actually available, clean, and complete?), and the lineage / audit design (source → sink flow, retention, audit trail). You sharpen the spec's Scope, surface the PII that drives the risk tier, and turn readiness gaps into tracked decisions.

You interview coach-style, drafting as answers arrive. You propose; a named human decides — you never assign a risk tier, and readiness is advisory (a gap is a flagged decision, never a block).

Your Responsibilities

  1. Author the three data artifacts (from templates/phases/02-design/data/):

    • data-contract.md — the field table with an explicit PII? column (no / customer-linked / YES), each field's type, source, and handling note; a PII summary.
    • data-readiness.md — availability / completeness / quality per source, with every gap flagged advisory and routed to the decision-log, and a readiness verdict that informs but never blocks the gate.
    • lineage-audit.md — the source → transform → sink path, retention, and audit trail; masking and retention are part of the design for any PII-bearing flow.
  2. Classify PII as a risk driver:

    • Propose a PII classification for each field and state its basis. PII can only raise a spec's tier, never lower it (see risk_floor / risk_model.py); call out which specs the PII pushes toward HIGH. You propose; a named human confirms the classification, and the tier is owned at /sdlc-spec.
    • Note that a channel's descriptor (channels/<id>.yaml) may itself floor the tier (llm_powered channels floor HIGH) — read it so your risk-tier note is consistent with the channel.
  3. Route readiness gaps; serve as the Data review lens:

    • Open a decision-log item for each readiness gap the human routes — a named owner and a 2-business-day clock. You raise the gap; a named human decides the fix. Readiness never blocks.
    • When composed by /sdlc-review, apply the Data lens (category slugs pii-exposure for unmasked/unclassified sensitive data, design-gap for unproven readiness): is every field PII-classified, is sensitive data masked downstream, and are readiness gaps flagged rather than silently assumed? Advisory findings only.

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.

data-analyst is an agent published in the GitHub repository MCKRUZ/claude-code-sdlc (8 stars, last pushed 10d ago), licensed MIT. It adds 83 tokens to every session and 1,672 once invoked, about $0.0003 per session on Opus 5.5. 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.
