ad-drift

<background_information> Read-only. Produces a drift list comparing the repo's operational docs against what the code actually does. Writes nothing — the user decides whether to fix the spec or the code. </background_information>

Step 2 — run checks.

AGENTS.md drift (if present):

• Stack — does the listed stack match package.json / pyproject.toml / Cargo.toml / go.mod / equivalent?
• Setup/build/test commands — do they match package.json#scripts, Makefile, or pyproject.toml?
• Quality gates — do referenced hook configs exist (.husky/, .pre-commit-config.yaml, .github/workflows/)?
• Repository layout — do referenced directories exist?
• Pre-approved commands — anything in the list missing from the toolchain?

ARCHITECTURE.md drift (if present):

• Layers and boundaries — do the named directories exist? Sample 1–2 files per layer; are imports respecting the stated boundaries?
• Patterns — sample one handler / one repository / one entry point. Do they follow the documented pattern?
• No ## Active ADRs section — ARCHITECTURE.md must not duplicate the doc/adr/ directory index per ADR-0030 §2.

ADR drift (if doc/adr/ exists):

• Numbering — gaps or duplicates in doc/adr/NNNN-*.md?
• Status field — every ADR has one of proposed | accepted | deprecated | superseded by ADR-NNNN.
• Superseded chains — every "superseded by ADR-NNNN" target exists.

Spec drift (if doc/specs/ exists; structural integrity only — does NOT deep-audit spec text against code, deferred per ADR-0011):

• Numbering — gaps or duplicates in doc/specs/NNNN-*.md?
• Status field — every spec has one of draft | accepted | shipped | superseded by SPEC-NNNN.
• Superseded chains — every "superseded by SPEC-NNNN" target exists.
• Reciprocity — every task with non-empty Spec ref points to a spec that exists; every accepted/shipped spec has at least one entry in its Related → Tasks list.
• No checkbox UI — per ADR-0030 §1, Spec is decision-record (not tracking). Functional Requirements / Non-functional Requirements / Success Criteria must use plain bullets, not - [ ] checkboxes; implementation tracking lives in per-Spec tasks.
• Status / task aggregate alignment — when every task referencing a spec is done, the spec's Status should be shipped. A spec with all tasks done but Status: accepted is drift between work-unit completion and feature-level claim.

Documentation discipline drift (WORKFLOW.md §2 / ADR-0008). Audit narrative documents — README.md, AGENTS.md / CLAUDE.md, ARCHITECTURE.md, DESIGN.md, and prose pages under doc/ that are not lifecycle-managed artifacts under doc/product/, doc/specs/, doc/adr/, or doc/tasks/:

• Emoji — any present? Rule 3 forbids emoji anywhere (docs, code, comments, commits, skill outputs).
• Dates / version stamps / DRAFT markers / changelog blocks in narrative documents — Rule 2 forbids these. Lifecycle-managed artifacts under doc/product/, doc/specs/, doc/adr/, and doc/tasks/ are exempt.
• Business context first — does the first paragraph answer why the document exists, before what and how? Rule 4.
• Scope duplication — does the document copy material that is canonically owned by another file? Rule 5 requires linking, not copying.
• Speculation — phrases like "we might", "in the future", "could be added", or roadmaps without an ADR / task reference. Rule 1 forbids unfounded plans.

Source code (sample, not exhaustive — flag findings, not every match):

• Orphan TODO / FIXME — Rule 7. A reference to a GitHub Issue or a doc/tasks/NNNN-*.md task file makes it not orphan.
• Commented-out code blocks — Rule 7. Removed code lives in git history.

Single-responsibility drift (ADR-0030 / WORKFLOW §2 rules #9–#12):

• Definition-layer tracking UI (Rule #9) — grep ^- \[ \] / ^- \[x\] inside AGENTS.md, WORKFLOW.md, ARCHITECTURE.md, GUIDELINES.md, CONTEXT.md, doc/product/*.md. Definition documents must not carry per-item checkbox UI. Fenced code-block examples (PR-body templates, etc.) are illustrative, not pillar tracking.
• Directory-as-index duplication (Rule #10) — flag sections that re-state another layer's index: ## Active ADRs inside ARCHITECTURE.md or AGENTS.md; multi-bullet ## Architectural Principles digests paraphrasing each ADR; PRD ## Related → ADRs bullet lists enumerating the kit's ADR ledger.
• Kit-state in WORKFLOW.md (Rule #12) — grep ADR-[0-9]{4} in WORKFLOW.md. Universal philosophy must not cite kit-specific ADR numbers (downstream installs lack doc/adr/). Literature citations and generic doc/adr/ references are allowed.
• Cross-references that are decoration (Rule #11) — sample inline per ADR-NNNN refs in narrative documents and apply the load-bearing test: deletion leaves the surrounding statement intact → decoration; flag.

Step 3 — output. One line per finding, formatted: [file or section]: spec says X, code says Y. Suggested resolution: change spec / change code / discuss.

Group by artifact. If a category has no drift, print one line: AGENTS.md — no drift. etc. If an audited artifact does not exist, say so explicitly rather than reporting zero findings. The Documentation discipline drift category groups findings under Documentation discipline — <category>: ....

If something the user says contradicts what the code shows, surface the conflict. Don't silently trust the user; don't silently trust the code.

<output_contract> A drift list, no file written. Read-only operation. Empty result is reported explicitly ("no drift found across audited artifacts"), not silently. Missing artifacts are flagged, not skipped. </output_contract>

Next

• Address each finding with one of the three resolutions named in the format ("change spec / change code / discuss").
• For findings that require implementation: /ad-task to scaffold the fix.
• For workflow drift (where am I, what's stuck): /ad-next.
• For kit-version drift (state file behind current kit): agentic update.
