What it does

Evidence Citations is an agent skill from Prismer-AI/PrismerCloud. Build source-backed research answers and documents with a task-isolated citation ledger, verified quotations, and explicit evidence gaps.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `NOTICE.md`, `references/citation-formats.md` and `references/grounding-rationale.md`).

It sits in Research & Science, covering Citation management. The licence is MIT.

When your agent uses it

  • Tasks that involve Citation management

Example prompts

  • “/evidence-citations”

Requirements

  • Python 3

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Register retrieved URLs with sources.py --ledger add --title .
  2. Store fetched text in task scratch. Attach exact supporting quotations with
  3. Write a Markdown draft using the returned numeric citation IDs.
  4. Append the source list from render --cited-in to the draft.
  5. Run verify --strict --evidence. This checks citation consistency
  6. For PKF, map verified ledger URLs to the citation format in pkf-writing;
  7. Deliver requested files through assets/office-artifacts and cloud deliver.

What it can do on your machine

Read from SKILL.md and the folder at commit e5d9444. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Evidence Citations loads about 682 tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 323 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~682
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Evidence Citations

Use for research, comparisons, reports, and factual document generation. Retrieve through the available ingest/browser tools; a URL alone is not evidence. Read the actual source and distinguish its claims from your inference.

Resolve scripts/sources.py relative to this installed skill directory. Always pass an absolute, task-specific --ledger <scratch-dir>/citations.json. For Hermes, obtain the current scratch directory from execution context. Never reset a profile-global ledger or another task's ledger. Resume an existing ledger when continuing the same task.

  1. Register retrieved URLs with sources.py --ledger <path> add <url> --title <title>.
  2. Store fetched text in task scratch. Attach exact supporting quotations with quote <id> --text <quote> --from <source-file>; fabricated quotes fail.
  3. Write a Markdown draft using the returned numeric citation IDs. Unknown facts stay unresolved; preserve contradictory sources.
  4. Append the source list from render --cited-in <draft> to the draft.
  5. Run verify <draft> --strict --evidence. This checks citation consistency and attached quotations, not whether a source is truthful or entails a claim. Add --min-coverage 1 when every claim needs declared provenance; CJK claims are counted, and an unmeasurable draft fails rather than reporting coverage. Only numeric [n] Markdown is verified; footnotes/LaTeX require their own checks.
  6. For PKF, map verified ledger URLs to the citation format in pkf-writing; run the PKF validator separately. Do not claim the Markdown checker validates PKF.
  7. Deliver requested files through assets/office-artifacts and cloud deliver. A short chat answer can cite the same verified sources inline.

No credentials are needed by the ledger. Missing retrieval tools are a coverage blocker, not a reason to fabricate sources. See references/citation-formats.md and references/grounding-rationale.md for background; this task-isolation and Prismer delivery contract takes precedence over upstream host-specific examples.

render --replace-in replaces only one unambiguous terminal Sources section and writes atomically. Fenced examples remain untouched; a non-terminal or duplicate heading fails without modifying the draft. A lock timeout is a failure, not permission to delete another writer's lock or continue without exclusivity.

Can I use Evidence Citations in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Prismer-AI/PrismerCloud --skill evidence-citations -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/evidence-citations, .gemini/skills/evidence-citations, .github/skills/evidence-citations and .opencode/skills/evidence-citations in your project.

What does Evidence Citations need to run?

Going by SKILL.md and its folder, Evidence Citations needs Python for the scripts in its folder. Our summary lists: Python 3.

Does Evidence Citations access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Evidence Citations safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Evidence Citations use?

Evidence Citations is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Evidence Citations use?

About 682 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.5k tokens, read only when the agent opens those files.

What are the alternatives to Evidence Citations?
