Flow Ptr App

Create a Flow Production Tracking (FPTR) Toolkit App

This skill guides developers and pipeline engineers through building an FPTR app, following a spec-driven way — capture intent, check for reuse, write and validate a spec, plan, then implement, verify, release, and maintain against that spec. Tell the user which phase (below) you're starting before acting in it, so they can track progress and step in between phases.

App spec-driven lifecycle

Each step below that has mechanical how-to links to a references/*.md guide — read it while executing that step, not before; keep the skill itself light and pull in detail only when it's actually needed. Phases 2, 7, and 9 have no dedicated guide — they're about the spec and process rather than a tool/config action.

• Phase 1 — Requirements/Intent capture
  • Step 1.1 — Ask for the business need, and capture it in a short spec (one paragraph or a few bullet points) — what the app should do, on which context and environment it will run, whether it needs a UI, whether it needs toolkit hooks, constraints and acceptance criteria.
  • Step 1.2 — Find if an existing app / project setting / hook cover fully or partially the requirements, and confirm with the user whether later we will fork/extend from that tool or scaffold a new app from the starter template. Read references/existing-functionality.md while executing this step.
• Phase 2 — Specification — before cloning anything, write down what the app does:
  • Step 2.1 — Clarify the goal, the app name, dependencies on Flow PTR frameworks/engines, the environment the tool runs in (e.g. Sequence/Shot/Episode-specific), the entities involved, the settings schema, which hooks the tool may need to expose and why, whether it needs a UI, and its acceptance criteria.
  • Step 2.2 — Validate the spec before planning: check it for internal contradictions, missing edge cases (no-UI/headless path, permissions, multi-engine support), and security/data-privacy concerns (e.g. what PTR fields/entities the app reads or writes). Flag gaps to the user instead of assuming an answer; only move to Phase 3 once the spec is complete and consistent.
• Phase 3 — Plan/Design
  • Step 3.1 — Locate the project's pipeline configuration and figure out how it's set up (centralized vs. distributed). Read references/locating-config.md while executing this step.
  • Step 3.2 — Find or create a sandbox or a dev configuration if it doesn't exist. Read references/sandbox-dev-configuration.md while executing this step.
  • Step 3.3 — Clarify where the app's source code should live, and how it will be installed into the target configuration (dev path vs. install_app + switch_app). Read references/cloning-template.md and references/install-app.md while executing this step.
  • Step 3.4 — Break the spec into a technical plan: architecture decisions, file/module breakdown, sequencing of work, identification of risks or open questions. Where practical, decide to keep core logic separate from UI code (e.g. app.py/a logic module stays UI-agnostic, with dialog.py calling into it) — this is what lets Phase 6 exercise the tool as a headless command in tk-shell before wiring up the dialog. Read references/implement-app.md while executing this step for how that split plays out in code.
  • Step 3.5 — Split the plan into discrete, independently verifiable tasks/tickets, each with clear inputs/outputs and acceptance criteria, so that the work can be parallelized and tracked.
• Phase 4 — Scaffold
  • Step 4.1 — Clone the reference tool — tk-multi-starterapp by default, or whichever existing app Phase 1 found as a better fit. Read references/cloning-template.md while executing this step.
• Phase 5 — Implement against spec
  • Step 5.1 — Fill in info.yml and implement code with main logic starting in app.py and UI starting in python/app/dialog.py. Declare and implement hooks if applicable. Read references/app-manifest.md, references/app-hooks.md, and references/implement-app.md while executing this step.
• Phase 6 — Verify against spec
  • Step 6.1 — Test and iterate using Toolkit's "Reload and Restart" menu item, checked against acceptance criteria, not just "does it run". If possible and it has a dependency on UI, test first in tk-shell or a batch context, then in tk-desktop and then in the target DCC engine, if applicable. If app is a Menu Action Item, test it in the FPTR Desktop and then in the web UI. Read references/test-app.md while executing this step.
• Phase 7 — Change management
  • Step 7.1 — Commit in git, pushing changes only to the sandbox configuration, not production.
  • Step 7.2 — Future feature changes update the spec first (Phase 2, re-validating it per Step 2.2), then cascade forward through Phases 3-6 — the spec stays the source of truth, not the code.
• Phase 8 — Release to production
  • Step 8.1 — Once ready for release, warn the user about the implications of bringing to production the new changes. Analyse possible side effects or interruptions to workflow.
  • Step 8.2 — Tag a release and push the sandbox config changes to the production pipeline configuration. Read references/release.md while executing this step.
• Phase 9 — Maintenance
  • Step 9.1 — Treat post-release bug reports or new asks as spec changes, not code patches: update the spec first (back to Phase 2), validate it again, then re-enter Phase 3 and cascade forward through Phases 4-8 — the spec stays the source of truth for the life of the app, not just during initial development.

Reference guides — skip the phases

The phases above are one way to work through building an app — spec-driven, with an explicit plan/verify loop. If you're following a different process instead (your own tickets, a different planning method, or you're just experienced enough with Toolkit not to need the scaffolding), use this table to jump straight to the how-to you need. Each guide is self-contained and doesn't assume you've read the phases above.
