Moving the Queue Out of Git

The Problem

Since March, half of the commits in our web and iOS repositories touched planning files. Most of those commits changed nothing but planning text. A status flip, a re-rank, or a new “next due” date was a branch, a PR, a review, and a merge, because the queue lived in git.

Repo Commits, March to September 1 Touching plans/ or PLANS.md
web 627 313
iOS 652 353

Hello Weather is built across three repositories by coding agents. Two earlier posts describe the markdown system those agents used: Planning Skill: Living Documents, Not Project Management and Plans Are Disposable, Skills Are Durable. An index file ranked the work. A plans/ folder held one document per piece of work, and the PR that shipped a plan deleted it. It was a good memory for agents. It was a poor place for a human to look, and the owner is about to have much less time to look. That made the change urgent. The board had to become the only planning page a person opens, and everything off it had to be invisible to agents by default.

What the Markdown System Got Right

Some of it was worth keeping, and we kept it.

A plan written to the handoff standard is a spec an agent can execute cold. Overview, Context, Ground Truth with verified file paths, Implementation Steps, Tests, Success Criteria. Nothing in an issue tracker holds that as well as a file next to the code it describes.

Deleting the plan in the PR that ships it kept the folder honest. A plan that outlived its work was a bug, and we had a rule and a monthly sweep for it.

Reference material that never changes state, like a cost model or a merge runbook, was fine as a dated file. The trouble was only that it shared a folder and an index with the queue.

And git gave us diffs. When an agent rewrote a plan’s ground truth, the review saw exactly what changed. That is the one thing we gave up.

Where It Broke

The index was supposed to be pointers. By the end it was 257 lines under 22 headings: a current pick, a force-ranked table, a triggered-work table, a recurring-work table, and ten “reference groups” of links. The plans/ folder in web held 95 files and close to 2 MB, with the largest at 80 KB. The planning skill that taught agents to read all of that had grown to 298 lines.

Dates hid in prose. We had a rule that every dated action had to be a row in the index, and a sweep for dates that only existed inside a plan. Both were needed because the format had no date field.

There was no way to assign anything. The designer needed to see the work waiting on them without reading git, and “assigned to” was a word inside a paragraph.

Cross-repo links rotted. The web index linked to ../ios/plans/*.md and ../android/plans/*.md. Every rename on one side broke a link on another.

Issues had been demoted to a scratch buffer. The old rule was that the steady state is zero open issues across the org, and an open issue was a capture waiting to be drained into a plan. So the tool GitHub already gives you for tracking work was the one thing we were not tracking work in.

The Move

The rule after the move is one fact, one home:

Fact Home
Priority, ownership, waits, and dates one org Project across the three repos
Problem, evidence, and decisions a GitHub issue
In-flight implementation spec plans/<name>.md
Permanent research or runbook a dated file in docs/
Durable rule AGENTS.md or a skill

Every plan was pre-sorted in comments on one tracking issue, and the owner approved the sort before anything was converted. Then, in web: 22 files moved to a new docs/ folder with the status sections removed and a provenance note added. Two in-flight specs stayed in plans/. The other 71 became issues and were deleted. Git history is the archive. Each converted issue links a permalink to the file at the last commit before the migration, so git show <sha>:plans/<file>.md still retrieves the full document.

We chose not to paste plan bodies into issues. An issue body caps at 64 KB, has no diff history, and stale ground truth in an issue reads as current. Instead each converted issue follows a short template:

Standing: owner-requested, decided | agent-suggested, unconfirmed | speculative

**What:** one paragraph.
**Why / evidence:** one or two lines.
**Decisions already made:** bullets, if any.
**Links:** related issues, PRs, docs, or a live spec.
**Reference PR:** #N, if banked.
Snapshot of `plans/<file>.md` at <sha> — <permalink>. Ground truth not re-verified since; re-verify before building.

The migration day created 246 issues across the three repositories. The web PR was +487 and −33,494 lines; iOS was +521 and −49,952; Android was +145 and −4,388. The web index went from 257 lines to under 50: a ranking thesis, a pointer to the board, and a catalog of the two specs and the reference docs. No queue, no status, no dates.

The “banked PR” idea from The Warehouse of Closed PRs survived. An issue for parked work carries a Reference PR: line, and a monthly job runs git merge-tree of each reference PR’s head against main and toggles a reference:conflicts label. On the first dry run all eight of the iOS reference PRs already conflicted, which is the expected state. The value is the shape of the change, not mergeability.

The Skill Points, the Script Reads

The neat part is how this combined with the pattern from Skills and Scripts. That post paired a short skill that teaches the model a workflow with a bin/ script that does the work. The old planning skill was 298 lines because it had to teach an agent a procedure. Read the index. Check the recurring table for due rows and the triggered table for fired triggers. Walk the ranked table, then update the current pick. Now the procedure is a script and the skill is policy.

bin/next in the web repo reads the board, open issues, and open PRs across all three repositories. Then it prints, in order: assigned open PRs, Waiting and Recurring rows due today or earlier, Active work, and the ranked Main queue. The skill says to answer “what’s next” in that order and never to reconstruct the queue from prose.

The grouping logic is the part with rules in it, trimmed here to the decisions:

def group(items, issues, pull_requests = [], all:)
  today = Date.today
  by_key = items.to_h { |i| [i[:key], i] }
  by_issue = issues.to_h { |i| [i[:key], i] }
  # join board items to live issues; drop items whose issue closed
  items = items.select { |i| i[:open] }

  queue     = items.select { |i| i[:status] == "Queue" }
  waiting   = items.select { |i| i[:status] == "Waiting" }
  recurring = items.select { |i| i[:status] == "Recurring" }
  fired         = waiting.select { |i| due?(i, today) }.sort_by { |i| i[:next_due] }
  recurring_due = recurring.select { |i| due?(i, today) }.sort_by { |i| i[:next_due] }

  # a top-level initiative is active when it, or any descendant,
  # is assigned or has an open PR
  roots = tree_roots(queue)
  active_roots, main_roots = roots.partition { |root| active_in_subtree?(root, queue) }
  active = all ? trees_for(queue, active_roots) : active_paths(queue)
  main_all = trees_for(queue, main_roots)
  main = all ? main_all : limit_trees(main_all, MAIN_LIMIT)

  warnings = []
  warnings += (waiting + recurring).reject { |i| i[:next_due] }.map do |i|
    "#{i[:status]} item #{i[:repo]}##{i[:number]} has no Next due date"
  end
  unplaced = issues.reject { |issue| by_key.key?(issue[:key]) || descendant_of_project_item?(issue, by_issue, by_key) }
  warnings += unplaced.group_by { |i| i[:repo] }.map { |repo, list| "Unplaced open issues in #{repo}: #{list.size}" }

  { "warnings" => warnings, "assigned_pull_requests" => pull_requests,
    "active" => active, "main" => main,
    "fired_triggers" => fired, "recurring_due" => recurring_due }
end

Notice that “active” is derived, not stored. There is no In Progress status. An initiative is active when someone is assigned to it or to any sub-issue under it, or when a sub-issue has an open PR. Assignment is the only signal, so the board can’t disagree with itself about what is in flight. The two warnings are the two rules we used to enforce by sweep. One is a wait with no date. The other is an issue that is neither on the board nor under something that is.

The script is a module with exit NextCli.run if $PROGRAM_NAME == __FILE__ at the bottom. A Minitest file can load it and test the grouping with hand-built hashes and no network. Fifteen tests cover active derivation, hierarchy nesting, the rank cutoff, the warnings, and the bounded queries.

The GitHub API gotcha

The first implementation made few network requests, but the GraphQL work inside them was broad. The Project command fetched every field value type. Each repository query also walked linked pull requests and up to 30 cross-reference events for every open issue. A full bin/next run measured about 1,472 GraphQL points the day after the migration.

That number matters more than the request count. GitHub’s GraphQL API rate limit is normally 5,000 points per hour for a user. A tool that agents run whenever they ask what to do next could consume most of that shared budget in a few runs.

The follow-up change replaces the broad Project call with a paginated query that asks for the six fields the report uses. It drops issue timelines and lists open PRs once per repository. The required Fixes and Refs lines in PR bodies then connect those PRs to issues. The --repo option also narrows the repositories before any issue or PR calls happen. Normalized output against the live board did not change, while measured cost fell from about 1,472 points to 9.

Agents building GitHub tools should inspect GraphQL cost, not just count gh commands. Read the rate-limit response headers or request rateLimit { cost remaining resetAt }. Avoid broad fieldValues selections and nested history connections unless the output needs them. Apply repository and state filters before the network call, not after loading everything.

The board is cross-repo, so there is one implementation. iOS and Android each ship a wrapper that finds the web checkout beside the repo’s main checkout and hands off:

#!/usr/bin/env bash
# "What's next?" — delegates to the web repo's bin/next (one board, three repos).
set -euo pipefail
main="$(cd "$(git -C "$(dirname "$0")" rev-parse --path-format=absolute --git-common-dir)/.." && pwd)"
web="${HW_WEB:-$(cd "$main/.." && pwd)/web}"
[ -x "$web/bin/next" ] || { echo "bin/next: no web checkout at $web — set HW_WEB." >&2; exit 1; }
exec "$web/bin/next" "$@"

The git-common-dir call matters because agents work in worktrees, and a worktree’s .git is a file pointing at the main checkout. Resolving through it means the wrapper works from any worktree.

The permissions follow the earlier post’s rule too. The web and Android settings allowlist bin/next, bin/plans-reconcile, and the read-only gh project commands. Board edits, parenting, and closes still prompt.

Guardrails

The first version used three small jobs to replace the monthly sweeps we ran by hand.

bin/plans-reconcile originally ran in CI on every web PR. Every file in plans/ had to link an open issue on the board. Every actively owned top-level Queue issue needed a spec or a spec pending note. A spec held ahead of active ownership only warned.

The open follow-up retires that reconciler and both scheduled planning workflows. The weekly digest becomes a due item in the Recurring lane because it repeated the live board through an expensive scan. The monthly board audit and reference-PR rot check also become recurring work because they need human judgment. This removes permanent automation and its GitHub API traffic.

The original Monday workflow ran bin/next --all and posted the output on a pinned issue. It also needed a fine-grained token because the default Actions token can’t read an org Project or touch the other two repositories. Moving the review into the queue removed that credential and still puts the work in front of an agent when it is due.

Day Two: One Queue Instead of Five Buckets

The first design did not survive its first day of use, and the correction is worth recording.

The original board had a custom Bucket field with Now, Next, Later, Waiting, and Design, on top of GitHub’s built-in Status field. Rank restarted inside each bucket. A backlog label marked issues that were deliberately off the board. A needs-design label marked design work, which was also a bucket, which was also a view. There was a work-in-progress cap of two Now items per repository, and a Now item had to have an open PR.

By the next morning the contradictions were visible. Design was both a bucket and a filtered view. Status was present but ignored. Deferred work still had assignees from the import, which broke the ownership rule. And 169 imported backlog issues sat off the board where nothing would ever list them.

The second design, shipped the same afternoon, has one Status field with Queue, Waiting, Recurring, and Done. Main is the one force-ranked list: every top-level Queue initiative has a unique global rank, and sub-issues inherit their parent’s position. Design is a view of Queue items assigned to the designer, not a state. There is no backlog lane and no persistent inbox. Every open issue is either a Project item or a real sub-issue of one. Work that is not credible enough to parent or rank is closed as not planned.

The WIP cap went too. We normally carry one top-level initiative at a time, but the script now shows overlap under Active without a numeric warning. A cap the tool enforces gets gamed by reassigning; a list that shows the overlap gets read.

Migrating live meant two steps. The script first learned to read both models, mapping the old buckets onto Queue, so the board could be reconfigured while bin/next kept working. Then a follow-up PR removed the compatibility code, deleted the migration spec, and closed its issue with Fixes. The spec for the planning system was itself the first spec to go through the new lifecycle.
