description: Use when executing an implementation plan in the current session as the implementer yourself — your human partner chose inline execution, or no subagent tool is available

Executing Plans

Execute the plan yourself, task by task, in this session: no implementer

subagent per task, no reviewer per task. One fresh-context review of the

whole branch at the end.

Why inline: Subagent-driven development pays for a fresh implementer

and a fresh reviewer on every task, each re-reading the codebase from zero.

Inline execution pays for one context (yours) plus one reviewer at the end.

What it gives up is a fresh context per task and a second pair of eyes per

task. This skill keeps what those two things bought, by other means: the

brief is the spec, the ledger is your memory, TDD is the per-task gate, and

the final reviewer is the second pair of eyes.

Core principle: The plan already did the thinking. Execute it exactly,

prove each step with a test you watched fail and then pass, and leave a

record that survives your own forgetting.

Narration: between tool calls, narrate at most one short line — the

ledger and the tool results carry the record.

Continuous execution: Do not pause to check in with your human partner

between tasks. They chose inline execution to spend less, not to answer

"should I continue?" after every task. Execute all tasks from the plan

without stopping.

Rulings, not stalls. Conflicts, ambiguities, plan defects — decide them.

The spec is the binding authority, the plan is its argument, and your

judgment settles what neither answers. Record every decision in the ledger

as Ruling: <what you decided> — <why> — <what it costs if wrong>, and keep

going. Deviating from the plan without a ledgered ruling is a decision made

in secret.

Four things stop you, and only these: an irreversible or destructive

operation; a security-sensitive action; a side effect outside this worktree

that norms say you ask about first (a merge, a push to a shared branch, a

publish); and a plan so broken that every path forward is a guess. For

those, stop and ask.

When to Use

• You have a plan from superpowers:writing-plans and your human partner

chose inline execution at the handoff.

• Your harness has no subagent tool (see the per-platform references in

../using-superpowers/references/). Never fabricate a dispatch; run

the plan here.

• Tasks are mostly independent — the same precondition as

superpowers:subagent-driven-development.

A fully specified plan makes inline execution transcription plus testing:

it runs well on a mid-tier session model, and the one place the most

capable model earns its cost is the final review, which this skill

dispatches separately. Tell your human partner so when they choose inline.

Prefer superpowers:subagent-driven-development when your human partner

wants a review gate on every task, or when the plan is long enough that

its later tasks would run on a compacted context. Inline execution over a

long plan still works — the ledger is what makes it recoverable — but the

last tasks get the least of you.

Setup

Ensure the work happens in an isolated workspace: use

superpowers:using-git-worktrees to create one or verify the existing one.

Never start implementation on a main/master branch without your human

partner's explicit consent.

Conversation memory does not survive compaction. An inline executor that

loses its place re-implements tasks whose commits already exist — the same

failure as a controller re-dispatching them, paid for in your own context.

Track progress in a ledger file, not only in todos. Harness todos are a

live view; the ledger is the record.

The workspace and ledger are shared with superpowers:subagent-driven-development

— same directory, same format — so a plan can change executors mid-flight

and the new one resumes from the same ledger.

• Each plan owns a workspace: at skill start, run

../subagent-driven-development/scripts/sdd-workspace PLAN_FILE — it

prints the plan's git-ignored directory

(<repo-root>/.superpowers/sdd/<plan-basename>/), home to every

artifact for THIS plan: ledger, briefs, review packages. Another plan's

directory is never yours to read or write.

• Check for this plan's ledger at <workspace>/progress.md. If its first

line names your plan file, tasks with a Task <N>: complete line are

DONE — do not redo them; resume at the first task without one. Their

commits exist in git even when your context no longer remembers making

them: after compaction, trust the ledger and git log over your own

recollection. A ledger whose first line names a different plan file is

another plan's progress: leave it and start your own, fresh.

• Create the ledger with its identity as the first line:

# SDD ledger — plan: <plan file path>.

• git clean -fdx will destroy the workspace (it's git-ignored scratch);

if that happens, recover from git log.

Read the plan once, note its context and Global Constraints, and create a

todo per task. If the plan names a Spec, read that too: the spec is the

authority the plan argues from, and conflicts inside the plan resolve

against it. A plan with no reachable spec gets a ledger note saying so —

rulings made without one are provisional.

REQUIRED SUB-SKILL: load superpowers:test-driven-development now,

before Task 1. It governs every step of every task below; a plan whose

steps already say "write the failing test first" does not exempt you

from reading it.

Before Task 1, scan the plan for conflicts between tasks. The plan's

Interfaces blocks tell you where to look: for every task that consumes

what an earlier task produces, one ledger row — the two tasks, what one

produces against what the other consumes, and what you found. Tasks that

share nothing get no row; a plan whose tasks share nothing gets the single

line Pre-flight: no shared interfaces. Rule on each conflict a row

surfaces with the spec as the binding authority, record the ruling beside

its row, and start Task 1. Each task's own text is checked when you read

its brief, not here.

The Task Loop

Everything you print, and every tool result, stays resident in your

context for the rest of the session. Redirect long test output to a file

in the workspace and read its tail; read a brief, not the whole plan.

1. Take the task

• Run this skill's scripts/task-start PLAN_FILE N. It prints the brief

path and BASE (the commit the task's range is cut from) in one call.

Read the brief for every task, including ones you remember from setup:

what you remember is a summary, the brief has the exact values,

signatures, and test cases.

• Mark the task's todo in_progress.

Every tool call is a turn that re-reads your whole context. Bookkeeping

rides along with work — a ledger append in the same call as the commit,

never in a call of its own.

2. Work the steps

The plan's steps are already in RED-GREEN order; follow them in that

order under superpowers:test-driven-development, loaded at setup. A test

step's code is written first and run first. Watching it fail is a step,

not a formality — a test that passes before the implementation exists is

a finding about the test.

Every step that runs a command has an Expected: line. Run the command,

read its output, and compare. Three outcomes:

• Matches. Next step.
• The code is wrong. Use superpowers:systematic-debugging. Find the

cause; never patch the symptom to make the step's output match.

• The plan is wrong — a step contradicts the spec, an interface from an

earlier task doesn't match what this task consumes, a command that

cannot work. Rule on the smallest change that satisfies the spec, ledger

it as Task <N>: Ruling: <finding> — <what you decided and why>, and

continue. The ruling is carried, not remembered: later tasks that touch

the same interface read it from the ledger.

Commit as the plan's commit steps say. A task that spans several commits

is fine; BASE is what the review range is cut from, never HEAD~1.

3. The completion contract

Before a task's ledger line, all of the following are true, with evidence

in this session — not inferred from the diff looking right:

• Every test the brief names exists and ran in this task, and you read

the output.

• The final test run for the task passed — task-done is that run, and

it writes the command and result into the ledger line.

• Every Expected: line in the brief was compared against real output.
• Every deviation from the brief has a Ruling: line in the ledger.

REQUIRED SUB-SKILL: superpowers:verification-before-completion governs

the claim. If any item is missing, the task is not complete: finish it.

4. Complete the task

Run this skill's scripts/task-done PLAN_FILE N BASE -- <test command>

with the test command the brief names for the whole task. It runs the

tests, keeps the full output in the workspace, prints the tail, and — only

if they pass — appends the completion line to the ledger:

Task <N>: complete (commits <base7>..<head7>, tests: <command> → <result>)

A failing run records nothing; the task is not complete. When it records,

mark the todo complete and take the next task.

Final Review

Run ../subagent-driven-development/scripts/review-package PLAN_FILE MERGE_BASE HEAD

(MERGE_BASE = the commit the branch started from, e.g.

git merge-base main HEAD) and review from the file it prints.

With a subagent tool: dispatch the reviewer on the most capable

available model — the whole-branch review is a judgment task — using

superpowers:requesting-code-review's

code-reviewer.md, with the

package path, the plan and spec paths, the plan's Review Focus section

verbatim if it has one (the input classes and failure modes the plan's

tests do not exercise — the reviewer checks each deliberately), and a

pointer to the ledger's Ruling: lines so it can weigh the calls you

made. Specify the model

explicitly; an omitted model inherits the session's, which may not be the

most capable. This is the one fresh context the whole run buys. Do not

skip it, and do not replace it with your own read of the diff.

Without a subagent tool: read code-reviewer.md and perform that review

yourself against the package, as a separate pass after the last task's

ledger line. Write Final review: self-review (no subagent tool) to the

ledger, and say so in your final message: a self-review by the author is

weaker than a fresh reviewer, and your human partner decides whether that

is enough before merge.

Sort the findings before you act on any of them. The reviewer's severity

labels are advice; the gate is yours. Its "Declined to judge" list is

yours too: every line there is a ruling you make and ledger, exactly like

a plan conflict — `Final: Ruling: <behavior the reviewer set aside> —

<what a reasonable person using this software gets, and why that stands

or why it is now a finding> — <cost if wrong>`. Re-grade first, by effect: the

spec is a vision document, and a finding's grade is what a reasonable

person using this software gets if it ships, not whether the spec names

the input that triggers it — a reviewer who set a finding at Minor

because the spec was silent has graded the spec, not the effect. Then:

• Critical and Important enter the fix pass.
• Minor goes to the ledger as Final: minor (deferred): <one-liner>

and to your final message under "Deferred minors". Minors never enter

the fix pass, and never become rulings — a ruling is a decision about a

conflict, not a note that you declined a polish suggestion.

Fix the Critical and Important findings yourself — you are the

implementer here — in ONE pass. Each fix is verified by TDD, not by a

second reviewer: write the test that reproduces the finding, watch it

fail, make it pass, then run the whole suite. Record each in the ledger as

Final: fixed <finding> — <test name> RED→GREEN, suite <N>/<N>. A fix

without a test that failed first is not verified; a suite that is not

green after the pass means the pass is not over. Do not dispatch a

re-review: it would re-read a diff whose covering tests already answer

"addressed" and whose suite run already answers "broke nothing".

A finding you decide not to fix is a ruling — `Final: Ruling: <finding> —

<why the code stands> — <cost if wrong>` — and reaches your human partner

in the rulings list. There is no second fix pass.

Finish

Before you delete anything, collect every ledger line containing

Ruling: into your final message under "Rulings I made", in the order you

made them, each with what it costs if wrong, and every minor (deferred)

line under "Deferred minors". Both lists are exhaustive. Your final

message is the only place the decisions you took on your human partner's

behalf — and the findings you chose not to act on — reach them.

When the final review is clean and its fixes are committed, delete this

plan's workspace directory — the git history is the record now. Sibling

directories belong to other plans; leave them alone.

Common Rationalizations

Example Workflow

You: I'm using the executing-plans skill to implement this plan inline.

[Setup: worktree verified]
[Read plan once: docs/superpowers/plans/feature-plan.md; spec read]
[Resolve workspace: sdd-workspace docs/superpowers/plans/feature-plan.md — no ledger inside, fresh start]
[Pre-flight scan: 2 shared-interface rows, 4 self-consistency rows, clean; written to ledger]
[Create todos for all tasks]

Task 1: Hook installation script

[task-start plan 1 → brief read; BASE a1b2c3d]
[Step 1: write failing test — written]
[Step 2: run it — FAIL: install_hook not defined. Matches Expected.]
[Step 3: implement — written]
[Step 4: run it — PASS 1/1. Matches Expected.]
[Step 5: commit — d4e5f6a]
[Contract: tests ran, output read, no deviations]
[task-done plan 1 a1b2c3d -- npm test -- hooks → ledger: Task 1: complete (commits a1b2c3d..d4e5f6a, tests: npm test -- hooks → 1/1 pass)]

Task 2: Recovery modes

[task-start plan 2 → brief read; BASE d4e5f6a]
[Step 2: run failing test — FAIL, but on an import error: Task 1 exported
 installHook, brief consumes install_hook]
[Ruling: brief's consumer name is a typo against Task 1's Produces block;
 use installHook — Ledger: Task 2: Ruling: install_hook → installHook — matches Task 1 Produces — cost if wrong: one rename]
[Steps 2-5 as planned; commit b7c8d9e]
[task-done plan 2 d4e5f6a -- npm test -- recovery → ledger: Task 2: complete (commits d4e5f6a..b7c8d9e, tests: npm test -- recovery → 8/8 pass)]

...

[After all tasks: review-package plan MERGE_BASE HEAD; dispatch code-reviewer, most capable model]
Reviewer: One Important finding — progress reporting interval hardcoded. Two Minor.
[Re-grade: Important stands; minors → ledger as deferred]
[Fix pass: test_progress_interval_configurable RED → extract PROGRESS_INTERVAL → GREEN; suite 12/12; commit]
[Ledger: Final: fixed hardcoded interval — test_progress_interval_configurable RED→GREEN, suite 12/12]

Rulings I made:
- Task 2: install_hook → installHook (brief typo; cost if wrong: one rename)

Deferred minors:
- README lacks a usage example
- recovery.js could split verify/repair into two files

[Delete this plan's workspace — the record now lives in git]
