qstack-plan-close

A process for recording what happened after a software plan was executed, including differences between the plan and the actual work. It writes an outcome document alongside the frozen plan and execution records.

In plain words
What is it for?
Use it to close a completed QStack plan by comparing its predicted work with the execution board and notes, then recording the result in outcome.md.
Why use it?
It captures surprises, deviations, and unexpected costs so later plans can benefit from what the team learned.

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

qstack-plan-close 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 yesterday.

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.

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/qstack-plan-close

Turns a finished piece of work into compounding knowledge.

The plan is not the lesson. The lesson is the delta between the plan and reality: what diverged, what surprised you, what cost hours that nothing predicted. This skill captures that delta and writes it where the next plan in this area will read it.

The convention

qstack/compound_engineering/plans/<feature-slug>/
├── plan.html                  # BEFORE: what we predicted. Frozen once work starts.
├── board-events.js                # DURING: append-only card events, written by agents.
├── execution.md               # DURING: decisions, deviations, validation, and reviews.
└── outcome.md                 # AFTER: this skill writes it.

If the repo has qstack/compound_engineering/README.md, read it first: it may extend or override what follows. Also support the legacy compound-engineering/plans/<feature-slug>/ layout and its README. Prefer the QStack layout when both contain the requested feature. If neither plan root exists, offer to create the QStack layout before proceeding.

Hard rules

  • Never edit plan.html or legacy plan.md. The plan is frozen once work starts; divergence is recorded in outcome.md, not by rewriting history.
  • Never commit. Write files and stop. The user commits.
  • Do not implement anything. This skill only writes documentation.

Steps

1. Identify the plan folder

ls qstack/compound_engineering/plans/
ls compound-engineering/plans/  # legacy, when present

If the user named a feature, use it. If not, infer from the current branch and recent commits, then confirm with the user before writing.

2. Establish ground truth

Do not rely on the plan's claims. Gather what actually happened:

git log --oneline --format='%h %ad %s' --date=short -20 -- <paths the plan touched>
git log --all --oneline --diff-filter=A -- '<resolved-plan-folder>/*'

Then verify the shipped surface exists: ls the scripts, grep for the key symbols the plan promised. A plan that says it shipped foo_bar() and a tree with no foo_bar() is the single most valuable finding this skill can produce.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
