consistency-check

A read-only checker for validating related project documents called DAE artifacts, such as specifications and acceptance criteria. It checks whether their schemas are valid and whether the documents agree with one another.

In plain words
What is it for?
Use it to audit one feature's artifacts or check project-wide consistency, including whether documented identifiers match the code when suitable code-search tools are available.
Why use it?
It helps find mismatches before work moves to the next stage or before a change reaches continuous integration. It reports suggested fixes but does not change the files.

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

consistency-check 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 2d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

consistency-check

Cross-artifact validation for DAE — the methodology's take on Speckit's /analyze. Read-only: reports inconsistencies and suggests fixes; never mutates. Any agent may run it (mechanical validation, not judgment-heavy verification). checkpoint: null.

When to use

Before major pipeline transitions and as a CI gate.

  • Feature scope/engineer.consistency-check <slug> — one feature's artifacts
  • Project scope/engineer.consistency-check --project — project-wide invariants

Not for: fixing inconsistencies (run the suggested fix skill); within-one-artifact ambiguity (clarify); code risk (crap-analyzer).

Workflow

  1. Resolve + load — resolve the methodology root + manifest via ${CLAUDE_PLUGIN_ROOT}/scripts/dae_resolve.py (see references/resolving.md). Feature scope: load every artifact in features/NNN-<slug>/ + CHARTER.md. Project scope: load CHARTER.md + every feature.md frontmatter. For identifier lookups (does symbol X actually exist in the code?), prefer LSP find-definitions / workspace-symbols when an LSP MCP capability is available; fall back to grep + Read otherwise. See ${CLAUDE_PLUGIN_ROOT}/references/code-lookup.md. 1.5. Run the mechanical checks first${CLAUDE_PLUGIN_ROOT}/scripts/dae_ontology.py <feature-dir> (or --project). It executes every constraint that is a set operation over structured data — enumerations, functional properties, parent/child inverses, cycle detection, AC↔scenario coverage closure, Principle 7 disjointness — deterministically. Take its findings as given; do not re-derive them by reading the artifacts. They are tagged in the tables below as (ontology). See ${CLAUDE_PLUGIN_ROOT}/references/ontology.md.
  2. Run the judgment checks (below) — the rows the script cannot decide.
  3. Report — errors first, then warnings; each with location + a suggested fix (which skill to run). Do not apply fixes.
  4. Handoff — emit a summary.

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.

consistency-check is a skill published in the GitHub repository swingerman/engineer (144 stars, last pushed 6d ago), licensed MIT. It adds 53 tokens to every session and 1,299 once invoked, about $0.0003 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.
