What it does

Evidence Lock is an agent skill from mohitagw15856/pm-claude-skills. Write or rewrite a document in evidence-locked mode: no unsourced sentences — every substantive claim carries a footnote citing the exact passage in the user's provided sources, and anything unsupportable is explicitly marked. Use when asked to make a document fully sourced, add citations from my docs, ground a draft in the attached material, or produce something for audiences that will check (legal, board, regulators, enterprise buyers).

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Citation management. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Add citations from my docs
  • Ground a draft in the attached material

Workflow steps

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

  1. Index the sources first. Skim all provided material and note what each source can support. If sources are thin relative to the task, say…
  2. Classify each sentence while writing: substantive (factual claim, number, attribution, causal statement) → needs a lock; structural…
  3. Lock = quote-level, not document-level. A footnote cites the source and the passage: [3] → "Q2 churn analysis, §4: 'logo churn…
  4. No stretching. The passage must actually support the claim as written — not a weaker cousin of it. If the source says "churn rose in Q2"…
  5. Conflicts surface, never average. Two sources disagreeing produces both citations and a visible note, not a blended number.
  6. Inference is allowed but labelled. A conclusion derived from cited facts gets [inference from 2,5] — distinguishing sourced, inferred from…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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 Lock loads about 1.2k tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 593 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~145
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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); files beside SKILL.md are not scanned.

description
Write or rewrite a document in evidence-locked mode: no unsourced sentences — every substantive claim carries a footnote citing the exact passage in the user's provided sources, and anything unsupportable is explicitly marked. Use when asked to make a document fully sourced, add citations from my docs, ground a draft in the attached material, or produce something for audiences that will check (legal, board, regulators, enterprise buyers). Produces the document with numbered citations, a source map quoting each cited passage, and an unsupported-claims register.

Evidence Lock Skill

For most drafts, plausible is enough. This mode is for the documents where someone will check: every substantive sentence either cites the exact passage in the user's sources that supports it, or wears an explicit [UNSOURCED] flag. No third state.

What This Skill Produces

  • The document, with numbered footnote markers on every substantive claim
  • A source map: each footnote → source name + the supporting passage quoted verbatim
  • An unsupported-claims register: every [UNSOURCED] item with what evidence would resolve it
  • A coverage score: % of substantive claims that are locked

Required Inputs

Ask for (if not already provided):

  • The sources — pasted documents, files, or excerpts. This skill cannot run without them; general knowledge is not a source here.
  • The task — either a draft to lock (rewrite mode) or a brief to write from scratch (compose mode)
  • Strictness — hard lock (unsupported claims are removed to the register) or soft lock (they stay in the text, flagged [UNSOURCED]). Default: soft.

Locking Method

  1. Index the sources first. Skim all provided material and note what each source can support. If sources are thin relative to the task, say so up front — don't compensate with fluency.
  2. Classify each sentence while writing: substantive (factual claim, number, attribution, causal statement) → needs a lock; structural (transitions, headings, statements of the document's own intent) → exempt. When in doubt, it's substantive.
  3. Lock = quote-level, not document-level. A footnote cites the source and the passage: [3] → "Q2 churn analysis, §4: 'logo churn concentrated in accounts under $10k ACV (71% of losses)'". Citing a whole document is not a lock.
  4. No stretching. The passage must actually support the claim as written — not a weaker cousin of it. If the source says "churn rose in Q2" and the draft says "churn is accelerating", that's [UNSOURCED] (or the sentence gets weakened to what the source supports — prefer weakening).
  5. Conflicts surface, never average. Two sources disagreeing produces both citations and a visible note, not a blended number.
  6. Inference is allowed but labelled. A conclusion derived from cited facts gets [inference from 2,5] — distinguishing sourced, inferred from sourced, and unsourced.

Unsupported claims register

ClaimWhy it's unsourcedWhat would resolve it

Conflicts noted: [source A says X; source B says Y — surfaced at footnote n]

Quality Checks

  • Every substantive sentence has a footnote, an [UNSOURCED] flag, or an [inference from …] label — zero unmarked claims
  • Every footnote quotes the passage verbatim; spot-checking any quote against the source succeeds
  • No passage is stretched — each supports the claim as written
  • The coverage score is computed by counting, and low coverage is stated plainly, not disguised
  • Source conflicts appear in the text, not silently resolved

Anti-Patterns

  • Do not fill source gaps with general knowledge — in this mode the provided sources are the entire universe of evidence
  • Do not cite documents wholesale — a lock names the passage
  • Do not launder inference as citation — derived conclusions are labelled as derived
  • Do not quietly drop claims that can't be sourced in soft mode — the register exists so the author sees what's resting on air
  • Do not proceed without sources "just this once" — without sources this is a normal draft, and other skills do that better

Example Trigger Phrases

  • "Make a document fully sourced."
  • "Ground a draft in the attached material."
  • "Produce something for audiences that will check."
