evidence-citations

evidence-citations is a skill for Claude Code, Codex from juspay/xyne-spaces. It costs 33 tokens per session (344 once invoked), scanned A, original, Apache-2.0.

A method for explaining code using references to the exact file and line where behavior is shown. It separates facts confirmed in the code from conclusions inferred from searches or comparisons.

In plain words
What is it for?
Use it when documenting how code works, tracing writes and reads, recording missing callers or readers, and supporting findings with file-and-line references.
Why use it?
It makes explanations checkable and prevents claims based on files that were never opened or evidence that only seems plausible.

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

evidence-citations 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 10d 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

Evidence and citations

Every non-obvious claim carries a path/to/file.ext:LINE anchor. This is also what closes a path in an understanding run — a finding recorded without one is downgraded to an open conjecture, so an uncited explanation is not merely weak, it does not count.

  • Cite the line that actually shows the behaviour: the write, the query, the branch. Citing the type definition proves the entity exists, which was never in question.
  • Never cite a file you did not open. A plausible path is the easiest thing in this job to invent and the most expensive thing for a reader to discover is wrong.
  • Prefer two anchors that disagree over one that is tidy. "Written here, but also mutated here" is the finding.
  • When you searched and found nothing — no writer, no reader, no caller — say so explicitly and give the search you ran. An unreferenced table is a real and useful result, not a failure to look.

Separate verified from inferred in the document itself. Mark inference as inference ("appears to be", "no caller found in this repo") and keep it out of the summary lines a reader will quote. In the HTML, render anchors in monospace so they are visibly checkable, and keep the repo, branch and commit in the header so a stale citation can be dated rather than merely doubted.

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.
