drift-resolver

drift-resolver is an agent for Claude Code from dgalarza/claude-code-workflows. It costs 17 tokens per session (567 once invoked), scanned A, original, MIT.

An agent for finding and fixing differences between documentation and the source files it describes. Documentation drift means that instructions become inaccurate after the code changes.

In plain words
What is it for?
Use it to inspect changed source files, compare recent code changes, identify affected documentation, and update the outdated parts.
Why use it?
It helps coordinate updates across several files and sections when a change affects paths, commands, examples, tables, or described behaviour.

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-resolver 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 1mo 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

drift-resolver

Dispatched by /doc-sentinel:resolve when a doc file has extensive drift (>5 warnings from a single commit or changes spanning multiple sections). Handles cases too complex for inline resolution.

Input

Receives context about:

  • The doc file to update
  • The source files that changed
  • The specific drift warnings (from .doc-sentinel-drift.json)
  • The commit messages explaining what changed

Process

Step 1: Understand the Doc

Read the full doc file. Identify its structure — sections, tables, code blocks, path references, command examples.

Step 2: Map Changes

For each changed source file:

  • Read the current version
  • Run git diff HEAD~1 -- <file> to see exactly what changed
  • Note which doc sections reference this file

Step 3: Targeted Updates

Update each affected section:

  • Path references — find-and-replace old paths with new paths
  • Code examples — update to reflect new function signatures, imports, or usage
  • Tables (ports, env vars, commands) — update affected rows, add new entries, remove defunct ones
  • Prose descriptions — rewrite sentences that describe changed behavior. Match surrounding style.
  • Architecture diagrams (ASCII/Mermaid) — update component names, connections, or flow descriptions

Step 4: Coherence Check

After all updates, re-read the doc to verify:

  • No orphaned references to old names/paths
  • Tables are internally consistent (no duplicate rows, correct counts)
  • Cross-references to other docs still valid
  • Section ordering still makes sense

Step 5: Stage Changes

git add <updated-doc-files>

Do NOT commit — the parent /doc-sentinel:resolve skill handles the commit.

Budget

  • Max 10 source files analyzed per invocation
  • Max 15 Bash calls
  • Max 3 doc files updated per invocation

Rules

  • Never modify source code — only documentation
  • Preserve existing heading structure (do not reorganize sections)
  • When uncertain about behavioral changes, add <!-- doc-sentinel: verify this description --> rather than guessing
  • Match the existing doc's level of detail — do not add excessive prose to a terse doc or strip detail from a thorough one
  • If the doc references files that no longer exist and there is no clear replacement, mark with <!-- doc-sentinel: file removed, verify replacement --> instead of deleting the reference

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-resolver is an agent published in the GitHub repository dgalarza/claude-code-workflows (62 stars, last pushed 3d ago), licensed MIT. It adds 17 tokens to every session and 567 once invoked, about $0.0001 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 2026-08-30.
