dr-execute-step

A step-by-step coding aid that performs exactly one unchecked task from a project checklist and records proof that it is finished.

In plain words
What is it for?
Use it to carry out CHECKLIST.md one step at a time, run each step’s required check, and record the actual result.
Why use it?
It limits each work cycle to one planned action, reducing skipped tasks, untracked changes, and changes made outside the approved scope.

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

dr-execute-step 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Execute one step

Input: CHECKLIST.md. Output: one more checked step with its done-criterion output pasted beneath it. You do this for ONE step, then return. The loop lives in the orchestrator, not in you — that is what keeps a long change from drifting.

Procedure

  1. Re-read REQUEST.md (including Amendments) and CHECKLIST.md in full. Find the FIRST unchecked step. That is your entire job. Do not read ahead "to be efficient"; do not batch steps.
  2. Confirm the step still makes sense against the tree (a prior step may have failed silently). If the tree contradicts the step — file missing, test already passing, root identity occupied — do not improvise: record the contradiction under the step, commit, and return to the orchestrator (route: dr-plan-steps).
  3. Execute the action. Only files this step's spec item names may change. Mid-step discoveries ("this file also needs...") go to PARKED.md or, if the change cannot land without them, back through dr-spec-change as an amendment — never just typed in.
  4. Run the done-criterion command. Paste its real output (trimmed to the relevant lines) under the step. If it does not match expected: the step is NOT done — leave it unchecked, record the output and one line on the mismatch, and return to the orchestrator. Two failures of the same step = stop condition, in the standard format — canonical in dr-drive-harness §6's calibration note.
  5. If this step changed behaviour, update the map in the SAME commit — see "Map obligations" below. If it changed the packaging surface (pyproject entry points, CLI commands, MCP tools/schema, wheel layout), update scripts/wheel_smoke.py's pinned expectations and re-run the smoke in the same commit too — no gate runs it for you.
  6. Mark the box, update CHECKLIST.md — including its header State: line (next step, blockers), which is what a fresh session resumes from — and if the step is tagged [COMMIT] (or changed any file): git add this step's files, then run python tools/diff_budget.py <tranche-base> --ceiling <SPEC.md's ceiling> --paths <SPEC.md's declared areas> and read its DIFF_BUDGET_RESULT_V1.verdict. WITHIN/NO_CEILING: continue. EXCEEDED is a STOP in the standard format (decision, priced options, recommendation), not a footnote — an estimate-only ceiling trips on nothing unless read. Alongside it, run python tools/blast_radius.py --files <this step's actually git-added files> --symbols <this step's actually touched top-level defs, from the diff hunks> --against <tranche-base> (Rung G6, docs/map/INV-frozen-surfaces.md) and diff its frozen_surface_contacts/reachability output against THIS document's own Frozen-surface contact forecast and Blast-radius census sections in SPEC.md. Any frozen_surface_contacts entry not already named in SPEC.md, or any reachability entry whose direction is newly_dead/newly_live and was not predicted, is DRIFT — a STOP in the exact same format as diff_budget.py's own EXCEEDED, never a footnote (docs/ERRATA_EXECUTOR.md, "the frozen-surface stop did not hold"). No drift: continue. Then commit and push now.

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.

dr-execute-step is a skill published in the GitHub repository AHepi/DeepReason (140 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 1,887 once invoked, about $0.0002 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.
