A scheduled workflow that reads development-machine activity, records recurring symptoms over a chosen time window, and surfaces only small fixes for problems that persist. It can use system telemetry, command history, and a session index.

Use it to find recurring contention, slow or failing commands, and missing tools, then promote a selected small fix into a draft pull request.

It helps separate repeated setup problems from temporary annoyances and avoids filling the work queue with low-value suggestions. Daily and weekly runs use different lookback periods and output limits.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.01922
Opus 5.5	$0.00028	$0.00769
Sonnet 5.5	$0.00014	$0.00384
Haiku 4.5	$0.00007	$0.00192

Security

Grade A, and why

friction 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 18d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (queries/queries.test.ts, scripts/collect.sh, scripts/ledger.test.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Friction

Find what keeps slowing the setup down. Every symptom here recurs. Mid-week, only a blocker with a small fix is worth a change. Everything else waits for the weekly list, ranked by how many days it persisted.

The output budget is the point of this skill. A run that surfaces nothing is a correct run. Never pad.

Arguments

--window 1d (default): the daily run. Last 24 hours of osquery, Atuin, and the session index, about 5 minutes, offline. Reading the session index runs its incremental refresh first, so schedule the run after the day's other refreshes.
--window 7d: the weekly run. Last 7 days of the same sources, plus upstream changelogs, 20 to 30 minutes.
--day YYYY-MM-DD: run as of a past day, to backfill the ledger or replay a calibration day. Bound every query to the window ending that day, pass --day to every ledger command, and print the decision without delivering it.
pick <fingerprint>: the user asked for a below-the-cut item. Run scripts/ledger.ts outcome <fingerprint> picked, then open its draft PR as daily promotion does in Deliver, which records it filed.

The window sets lookback, sources, and budget. The steps and the ledger rules are identical for both.

Steps

0. Outcomes

Check the open Friction: PRs and record any outcome the ledger lacks (see Outcomes). A --day replay skips this step.

1. Collect

Run named queries over the window. Each source returns rows, not prose. For osquery and Atuin, run the source's queries in one call, with the run's day and the window length in days (1 or 7). Never retype the SQL.

It sees only local transcripts, so a quiet index means work moved to cloud sessions, not that friction stopped

What ships with it

17 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

friction is a skill published in the GitHub repository bendrucker/claude (18 stars, last pushed today), licensed MIT. It adds 70 tokens to every session and 1,922 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-22.
