evidence-miner

evidence-miner is a skill for Claude Code from squerne/open-career-skills. It costs 67 tokens per session (963 once invoked), scanned A, original, MIT.

A read-only tool for finding real work achievements in Git history, pull requests, and work documents, then turning confirmed evidence into STAR stories. STAR means Situation, Task, Action, Result.

In plain words
What is it for?
Use it to build an evidence-based story bank from repositories and work folders, with optional redaction for client or employer names.
Why use it?
It helps when achievements are hard to remember and prevents career claims from being based on guesses instead of records.

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-miner 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 12d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Evidence Miner

The other skills in this workspace refuse to invent facts. This one goes further: it harvests real ones. People systematically forget their own achievements; their git history doesn't. (Concept inspired by Play-New/apply-new, MIT: career evidence should come from work artifacts, and every claim should trace to data.)

Privacy contract (state it to the user up front, once)

Everything here is read-only and stays local: repo content is read on this machine and goes nowhere except into story files the user approves. Never run write/network git commands. If a repo involves a client or employer the user may not want named, offer to redact the name in the filed story ("a fintech client" instead of the name).

Step 1: Scope

Ask the user which repo(s) or work folders to mine (absolute paths), and roughly what period matters. If they own PRs on GitHub, gh widens the evidence.

Step 2: Harvest (bash, read-only, no permission theater)

Use the bash tool to execute read-only git and gh commands directly. Do not ask for permission for read-only git log/git shortlog/git show --stat/gh pr list commands; execute them and gather the evidence. Never execute anything that writes (no checkout, commit, push, config).

Per repo, run what the situation needs, typically:

git -C <repo> log --author="<user>" --oneline --since="12 months ago"
git -C <repo> shortlog -sn --since="12 months ago"        # their share of the work
git -C <repo> log --author="<user>" --stat --since="12 months ago" | head -400
gh pr list --repo <owner/repo> --author "@me" --state merged --limit 50 --json title,mergedAt,additions,deletions  # when gh is available

Also skim CHANGELOGs, ADRs, or docs folders the user points at.

Step 3: Detect achievement signals

Look for clusters, not single commits: a shipped feature (branch/PR series landing in one area), a performance or cost fix (commit messages with numbers: "cut build from 12m to 3m"), an incident or bug saga resolved, a migration or refactor completed, sustained ownership of a subsystem (shortlog dominance), tooling or process the team adopted.

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.
