project-groundwork

project-groundwork is a skill for Claude Code, Codex from aethrox/doctrine. It costs 84 tokens per session (1,020 once invoked), scanned A, original, MIT.

A review process for an existing draft specification or README, checking whether its requirements are clear, complete, consistent, and testable.

In plain words
What is it for?
Use it to review a draft, resolve blocking gaps, and record the answers in the document and an existing decision record when available.
Why use it?
It finds contradictions and unresolved decisions before implementation, then gathers only the questions that block progress.

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

project-groundwork 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 5d 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 — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Groundwork

A draft document is not settled just because it exists; internal contradictions and unresolved TBDs hide in it until implementation runs into them. This skill's defining constraint, from ISO/IEC/IEEE 29148's requirements quality characteristics: a specification is checked against a fixed, named set of properties rather than a vague sense of whether it "looks done." The standard distinguishes properties of one requirement (unambiguous, verifiable) from properties of the document as a whole (complete, consistent); both are checked here.

This is a narrow, existing-document job, distinct from three doctrine skills it would otherwise overlap:

  • wayfinder charts open decisions when no document exists yet, or the whole effort is too large to spec in one pass. This skill starts from a draft that already exists.
  • grilling is the general-purpose interview technique for closing any known-versus-needed gap. This skill uses grilling's batching discipline for the specific gaps this skill's own scan surfaces; it does not redefine the interview mechanics.
  • domain-modeling owns the glossary and ADR format that decisions get recorded into over time. This skill's distinct output is writing the resolved decision into the source document itself, in the same step, not only into an ADR.

Phase 1: Scan against the quality characteristics

Read the draft and check it against each of these, noting concrete violations, not general unease:

  • Unambiguous: does any section allow more than one reasonable interpretation?
  • Consistent: do any two sections state something that cannot both be true?
  • Complete: is there a TBD, a placeholder, or a decision the document assumes was made elsewhere but never states?
  • Verifiable: is there a claim or requirement with no way to confirm it was met?

List each violation with its location, not a summary judgment that the document "needs work."

Phase 2: Separate blocking gaps from ones that can wait

Not every violation found in Phase 1 blocks implementation from starting. A genuinely blocking gap is one where guessing wrong would cost real rework; a non-blocking one can be left as a stated open question and revisited later. Sort the list before asking anything, since a batch of ten questions when only three are load-bearing wastes the reader's attention on the other seven.

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.

project-groundwork is a skill published in the GitHub repository aethrox/doctrine (18 stars, last pushed 23d ago), licensed MIT. It adds 84 tokens to every session and 1,020 once invoked, about $0.0004 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.
