Work on TPP
Documented in depth: Claude Code has amnesia. So do PRs, changelogs, and your future self.
A Technical Project Plan (TPP) is a living handoff document: it carries research,
design decisions, failed approaches, and next steps across sessions, so the next
session (or the next engineer) continues instead of restarting.
Make progress on the referenced TPP. Determine the current phase and take
appropriate action.
Required Reading First
Before any work, you MUST read:
- The project's instructions:
AGENTS.md, plus CLAUDE.md when present
- The project's TPP guide:
docs/TPP-GUIDE.md if it exists; otherwise the
bundled reference TPP-GUIDE.md
Process
- Read the referenced TPP. It will live in
_todo/, in a priority folder
(_active/, _p1/…_p4/), or in a documented feature integration queue
matching _feat-<name>/ if this project uses them.
- Identify the current phase.
- Do the work for that phase.
- Update the TPP with progress and discoveries — gotchas, rejected approaches,
and the why behind decisions, not a transcript.
When context runs low before the work is done, invoke the handoff skill rather than
letting the session end silently. When the TPP is complete, move it to _done/.
Adapting for your project
- Create a project
docs/TPP-GUIDE.md (start from the bundled reference)
and tailor the layout, frontmatter fields, and template to your conventions —
the project guide always takes precedence over the bundled copy.
- Extend the required reading list with your high-value docs
(
DESIGN-PRINCIPLES.md, TDD.md, architecture decisions). Every listed file
is read on every invocation, so keep it short.
- Automate durable reminders portably. Put the TPP update requirement in
the repository's
AGENTS.md, or use a supported project hook or automation
that prompts the coding agent to update the active TPP before a task ends.
