os-big-picture

One file, BIG-PICTURE.md, where os-whats-next already looks for a backlog. It answers "where are we now" - not a plan, nothing in it a promise. Write it in the user's language; paths stay English.

When to use it. The user asks where the project stands, or there is no BIG-PICTURE.md yet → the full pass: describe, census, signals, backlog. A session report was just written → the fold-in: only the rows that session touched. Both re-measure, because a session that moves no row is the one after which the dates go quietly stale.

Step 1 - find the file, and never clobber it

BIG-PICTURE.md in the project root, and it may already be somebody's own work. Everything this skill writes lives between <!-- open-steps:begin --> and <!-- open-steps:end -->; no markers → append at the end; no file → create it, and add it to this clone's ignore list, never to .gitignore:

f=BIG-PICTURE.md; e="$(git rev-parse --git-dir)/info/exclude"
git check-ignore -q "$f" || git ls-files --error-unmatch "$f" >/dev/null 2>&1 \
  || grep -qxF "$f" "$e" 2>/dev/null || printf '%s\n' "$f" >> "$e"

Each of the three is a reason to leave it alone. Say in one line that you did it; git add -f BIG-PICTURE.md shares it instead. Never read Last worked on or Signal back out of the file - only Stage and the queue carry forward.

Step 2 - the census, measured by the script

bash "${CLAUDE_SKILL_DIR}/scripts/census.sh" .

An AGE line, then one measured PART row per part: path, last worked on, commits in six months, whether anything outside reaches it, the signal.

Step 3 - reading what it printed

When the AGE line says young, write one line directly above the table, before the header row: "This project is N days old. Nothing here can be quiet for six months yet, so the Signal column will only start to mean something from the date the script gave." Every active is then a fact about the calendar, not the code. On an ok line, write no such note.

Step 4 - the backlog, sourced and never invented

Three sources, each item naming its own: session reports in ~/.claude/open-steps/reports/<project>/ (⏳ deferred rows, "Anything needed from you", recorded debt); Step 3 (each unused part, one retire candidate); the user, by hand. Nothing else - a gap you noticed while reading the code is not a task, so say it in the chat and let the user decide.

Step 5 - the tracker, if there is one

An offer, never a quiet action, and only for the "What is next" rows.

1. Find it, never install it. gh repo view --json hasIssuesEnabled -q .hasIssuesEnabled, then any tracker already connected. Nothing connected is a normal answer: say so under "What is next", then Step 6.
2. Search before you propose: gh issue list --search '<a few words>' --state all --json number,title,state. A closed ticket is still a match; where the search did not run, say so.
3. Ask, then create. Plain lines through os-ask-simple; on a yes create those and nothing else, and only where this pass measured what the item rests on. Write each number back into its row, same pass.

Step 6 - plain words, before it is written

Put every sentence in the block through the os-say-simple rules first: one sentence one idea, active voice, one word for one thing. That covers the prose, the "What it does" column and the backlog items - never a measured cell.

The shape

<!-- open-steps:begin -->
_Measured <date>. Stages are dated where they stand; anything undated in this
file is not measured._

## What this is

<Three or four sentences. What the product does, who runs it, what it runs
on. No jargon - a reader who has never seen the code.>

## What is in it

| Feature | What it does | Stage | Last worked on | Signal |
|---|---|---|---|---|
| <plain name> | <one line> | live (1 Sep) | 1 Sep | active |
| <plain name> | <one line> | not checked | 28 May | stable |

## Worth retiring

<One line each: what it is, how long unused, what would break. Empty is a
result - write "nothing found" and keep the heading.>

## What is next

- <item> - <source>
- <item> - <source> - #<ticket number, once one exists>

_Age and wiring measured <date>, fresh this pass. Stage comes from session
reports and is only as current as the date beside it._
<!-- open-steps:end -->

Stage is one of building, built - not shipped, live, retired or not checked, and it carries the date it came from, always - live (12 Jul), never bare live, and not checked never dated. When the newest date in that column is months behind the newest commit, the reports have stopped: say so.

Hard rules - these rules are the skill

1. Measured and assumed never mix. Last worked on and Signal are script output every time. Stage has no measurement.
2. Enumerate, never guess. The parts come from the script.
3. Quiet is not dead. No retire candidate on age alone: quiet plus wired in is stable, which is what stops the map recommending you delete a working product.
4. Never invent work. Every backlog item names its source.
5. Never clobber. Only between the markers. Their file stays theirs.
6. Recommend, never act. No deleting code, moving files, opening a pull request. "Worth retiring" is a sentence, not an action.
7. Plain words. A feature is named as the user says it, not as the folder.
8. One screen per section. Twelve features is a wall - group and say so.
9. A ticket only after an explicit yes. Rule 6 is the code, this is everyone else's inbox.
10. The plain-words pass never touches a measured cell.
11. Re-measure, never quote. A number read out of the file is a number about the past wearing today's date.
12. Every claim carries its date or says it has none. A map that cannot go visibly stale will go invisibly stale.

Why the rules are there, the traps the script cannot catch, and a worked example: references/.
