trace

trace is a skill for Claude Code from ai-analyst-lab/ai-analyst. It costs 37 tokens per session (774 once invoked), scanned A, original, MIT.

A command that creates a self-contained web page linking each reported number to the SQL query that produced it. It labels whether each link was directly cited, matched by value, inferred, or not found.

In plain words
What is it for?
Use it after an analysis when someone asks where a number came from or wants to inspect the query behind it.
Why use it?
It makes unsupported or unmatched numbers visible instead of hiding them. This gives readers a way to inspect the evidence behind an analysis.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 scripts/analysis_trace.py build.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

trace 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/trace: expose the query logic behind every number

Renders and shares one self-contained HTML that ties each reported number (a finding) back to the query that produced it, labeled by confidence: cited (the agent named the query), value-match (a query's captured result_value equals the number), or inferred (nearest query in time). Unmatched findings and orphan queries are shown, not hidden. An unverified number is the most important thing to surface. This is the on-demand artifact for any "prove it" moment.

It reads the analysis record, query log, bounded result previews, findings manifest, action log, and reconciler.

Steps

  1. Resolve the analysis. Read the current analysis record:

    python3 -c "
    import sys; sys.path.insert(0, '.')
    from helpers.knowledge.analysis_context import current_analysis
    print(current_analysis() or '')
    "
    

    If there is no current analysis, there is nothing to trace yet. Say so and stop (or, for a past run, point build_trace at that analysis_id explicitly).

    Interactive analysis provenance always remains under the repository's top-level working/ directory. The analysis output directory is only where the shareable HTML and written review go. Do not create or copy another current-analysis.json, and do not relocate the query log.

  2. Verify the findings manifest. If reported numbers were not registered, do not pretend a trace exists. Read the saved analysis and query log, then register each reported number with the exact supporting query IDs. Record derived values with their formula and source finding IDs. Never label a timestamp-only guess as a verified link.

  3. Build + render the trace. Use the lifecycle command so all inputs come from the canonical provenance store and the HTML goes to the recorded output directory:

    python3 scripts/analysis_trace.py build
    

    This also writes working/provenance_<analysis_id>.json and working/trace_receipt_<analysis_id>.json.

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.

trace is a skill published in the GitHub repository ai-analyst-lab/ai-analyst (322 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 774 once invoked, about $0.0001 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 2026-09-12.
