agile-github-sync

This tool keeps an AgilePlace (LeanKit / Planview) board up to date with what is happening in a GitHub repository. You run one command, by hand or on a schedule. It reads the repo's issues, sub-issues, blocking relationships, and GitHub Projects v2 board, then creates and updates AgilePlace cards to match. There is no per-project manifest; everything is derived from the live GitHub state.

What a run does

With --apply, each run:

1. Creates a card for every active issue, epics and tasks alike. Cards are matched to issues by the card's external-link URL, with the card's customId as a fallback. Issues closed as NOT_PLANNED/DUPLICATE never get new cards; if one already has a URL-matched card, the run retires it to Done and clears its stale blocked state without syncing its metadata back to GitHub.
2. Moves each card to the lane for its stage. For open issues, the stage is the issue's Status on the GitHub Projects v2 board (Backlog / Ready / In progress / In review / Done), which is the source of truth. A closed issue always resolves to Done, even when its Project item retains a stale Status. Issues that are not on the Project fall back to a stage derived from labels, assignees, and open PRs. Lanes are matched by title among leaf lanes; if a match is ambiguous, the card stays where it is. If reading the Project fails outright -- or technically succeeds but yields zero recognized statuses for a Project that does have issue-linked items (e.g. a misconfigured GH_PROJECT_STATUS_FIELD) -- no active-issue lanes are changed that run, so the fallback cannot mass-move the board. Authoritative NOT_PLANNED/DUPLICATE retirement still moves an existing card to Done. New cards created during such a run are left laneless rather than fallback-laned; a later run lanes them normally once the read succeeds.
3. Mirrors sub-issues as parent/child card connections. Existing children are read per epic through the paginated AgilePlace connections endpoint. Links are removed only when both the native GitHub sub-issue snapshot and the AgilePlace child snapshot are authoritative; either read failing makes that epic add-only for the run. LeanKit then rolls child progress up to the parent on its own.
4. Marks a card blocked while any issue blocking it is not Done, and clears the blocked state otherwise. A NOT_PLANNED/DUPLICATE blocker is known Done, so it cannot block dependents forever; a blocker missing from the complete issue snapshot remains incomplete (fail-closed).
5. Reconciles metadata and dates in both directions using a three-way merge against .sync-state.json. GitHub labels and milestone sync with card tags, and removals carry over in both directions. The Project's Start and Target date fields sync with the card's plannedStart and plannedFinish; if both sides changed the same date, the AgilePlace value wins.

Field updates queued for an existing card -- lane, tags, dates, and blocked state -- are combined into at most one versioned PATCH per run, so a stale write fails instead of silently overwriting someone else's edit. A version-less card is refetched once; the PATCH proceeds only if every queued field still matches that fresh snapshot, and otherwise the run aborts before saving merge state. Card creation and hierarchy connections use separate POST/DELETE requests, and GitHub-side writes are issued separately. Dry run is the default: python sync.py prints every planned action and writes nothing.

Before the first live run: API-VALIDATION.md records which API shapes are confirmed and which still need a one-time check against the live APIs (the AgilePlace connection, blocked-state, tag, and date writes, and the gh project reads). Known deferred work (pagination beyond about 1,000 records, cross-repo sub-issues, run locking) is tracked in HARDENING.md. Start with a disposable board and repo.

Point it at a repo

cp .env.example .env

Fill in TARGET_REPO_PATH (the local clone), the AGILEPLACE_* values, and the GH_PROJECT_* values, then grant the Projects scope with gh auth refresh -s project. Every gh call runs with its working directory set to TARGET_REPO_PATH, so gh finds the repo through that clone's remote; no owner or repo name is hardcoded here.

The script is plain Python (3.10+, standard library only) and the same python sync.py works in PowerShell, cmd, and bash.

If your board columns don't match the standard five stages, set STAGE_LANE_MAP to pin stages to your lanes. You can list several lanes per stage: the first is where cards get moved, and any of them counts as "already in that stage". See .env.example. Without the map, lanes are matched by title and card status, and an ambiguous match leaves the card alone.

Run

python sync.py            # dry run: prints what it would do, writes nothing
python sync.py --apply    # create/move/connect cards and sync metadata and dates (needs a full .env and token scopes)

Runs are idempotent, so any schedule frequency is fine. With no AgilePlace token it still reads GitHub through gh, but forces dry-run mode and makes no writes. If the target repo has no reachable remote, it prints a notice and does nothing.

Keep it always in sync

• Windows (Task Scheduler): powershell -ExecutionPolicy Bypass -File .\Register-BacklogSync.ps1 registers a task that runs sync.py --apply every 30 minutes, weekdays 07:00 to 19:00, only while you are logged on (no stored password). Output goes to sync.log. Remove it with -Unregister.
• Linux/macOS (cron):

  */30 7-18 * * 1-5  cd ~/github/agile-github-sync && python sync.py --apply >> sync.log 2>&1

The account running the schedule needs python and gh on PATH, gh auth login plus gh auth refresh -s project completed, and a filled-in .env.

Layout

• sync.py: orchestration. Creates, moves, connects, and blocks cards; reconciles tags and dates; sends at most one field-update PATCH per existing card.
• stages.py: pure stage derivation, blocked-reason text, and lane/title matching (unit-tested).
• reconcile.py: pure three-way set and single-value merges (unit-tested).
• ghkit.py: GitHub via the gh CLI (issues, sub-issues, open-PR and blocked-by reads, label/milestone writes).
• ghproject.py: GitHub Projects v2 via gh project plus GraphQL (Status reads and field-id-keyed date reads/writes).
• agileplace.py: AgilePlace io v2 (board, cards, lanes, tags, dates, connections, blocked state).
• config.py: .env config. tests/: pytest (pytest -q).

The one-time initial stand-up (labels, milestones, first issues, adding issues to the Project) is a separate throwaway step that lives outside this repo. This tool only maintains the ongoing mirror.
