drift-update

drift-update is a skill for Claude Code from wardawgmalvicious/agent-config. It costs 203 tokens per session (3,707 once invoked), scanned A, original, MIT.

A workflow for applying drift-handoff briefs, which are written instructions for fixing differences found during a codebase audit.

In plain words
What is it for?
Use it to read every brief, apply its specified edits, run its verification steps, and mark the brief complete.
Why use it?
It keeps fixes tied to the audit record, checks that each fix works, and records when the work is done.

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

drift-update 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 3d 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 — 289 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Drift update

Execute the briefs on disk. /drift-audit finds the drift, /drift-handoff writes it down, and this skill is the third turn: it applies what the briefs specify, verifies with the steps the briefs supply, and records that it ran.

The briefs are the instruction set. This skill contributes the loop around them — resolution, a staleness gate, triage, checkpointing, and a stamp — not the content of any edit.

Read every brief from disk, every time. Never reconstruct one from the conversation, from memory of an audit, or from a summary, even when this session produced it. The file is the contract; the transcript is not.

Repo-relative paths below are relative to the agent-config repo (C:\Repos\Personal\agent-config), not the session's cwd. ~/.claude/skills is a junction into that repo, so this skill can fire from a session in any repo — resolve paths against agent-config regardless of where it fired.

1. Preconditions and session posture

Fresh session is the intended way to run this. A brief is written to be read cold; running cold is what proves it was written well.

Check whether a /drift-audit report is present in the conversation — its own structure (## Audit window plus ## Recommended actions), not a mention of one. If it is, this is a warm run. Warm is allowed, with two limits:

  • Refuse a brief whose targets include skills/drift-audit/, skills/drift-handoff/, or skills/drift-update/. Editing the skill that produced the briefs, in the session that produced them, is the one case where warm is actually unsound. Name the brief, say why it was skipped, and tell the user to run it from a fresh session.
  • Cap the run at three briefs. The audit turn is the expensive one; its fetched sources and artifact sweep are still resident. Apply the first three eligible briefs, stop, and report the remainder as pending a fresh session. The cap counts briefs this run applies; one that 4.2 stamps as already-applied costs a grep and an append, so it does not consume the budget. Compaction part-way through an edit is worse than a restart, because a compacted session is a lossy warm one — strictly worse than a cold one.

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.

drift-update is a skill published in the GitHub repository wardawgmalvicious/agent-config (1 stars, last pushed today), licensed MIT. It adds 203 tokens to every session and 3,707 once invoked, about $0.0010 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 2026-08-31.
