Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.00972 |
| Opus 5 | $0.00046 | $0.00486 |
| Sonnet 5 | $0.00018 | $0.00194 |
| Haiku 4.5 | $0.00009 | $0.00097 |
Grade A, and why
mine-claude-md 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 13d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mine-claude-md
Harvest non-obvious knowledge out of a project's recent Claude Code sessions and turn it
into proposed CLAUDE.md additions — without inventing anything. This runs a bundled
dynamic workflow that mines candidates in parallel, has independent skeptics adversarially
challenge each one (reject-by-default), loops until the well runs dry, and synthesizes the
survivors into a paste-ready report. It only proposes — it never edits your CLAUDE.md.
Requirements (check first)
This skill drives Claude Code's dynamic workflows feature. Before running, confirm:
- Claude Code v2.1.154+ and a paid plan (Pro/Max/Team/Enterprise) or API access.
- Workflows are enabled (
/config→ Dynamic workflows, ordisableWorkflowsnot set, andCLAUDE_CODE_DISABLE_WORKFLOWSunset).
If workflows are disabled, the Workflow tool call below will fail. If it does, tell the user
to enable Dynamic workflows in /config and re-run — do not fall back to doing the mining
inline (the whole point is the parallel adversarial-verification harness).
Resolve the bundled workflow path
The orchestration script ships inside this plugin. Resolve its absolute path now — this works whether the plugin is installed at the personal, project, or plugin level, and regardless of the current working directory:
echo "${CLAUDE_SKILL_DIR}/../../workflows/mine-claude-md-from-sessions.workflow.js"
Use the path printed above as the scriptPath argument. Do not retype or guess it.
Gather inputs
Determine the workflow args before launching:
projectPath(required): the absolute path to the repo to mine. Default to the current project root (${CLAUDE_PROJECT_DIR}or the cwd) unless the user named a different repo.sessionCount(optional, default 20): how many recent sessions to read.maxRounds(optional, default 6): safety cap on mining rounds.dryRounds(optional, default 2): consecutive empty rounds that mean "done".miners(optional): miners per round; auto-scales 2–4 from session count if omitted.
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.

mine-claude-md is a skill published in the GitHub repository ragnar-pwninskjold/tech-snacks (132 stars, last pushed 25d ago), licensed MIT. It adds 91 tokens to every session and 972 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
