tech-lead

Locks contracts and architecture decisions before specialists build, and unblocks them when the design is unclear.

looks for

  • a change that crosses module or service boundaries
  • a new or changed endpoint, event or table
  • a proposed new dependency
  • an implementer asking "how should this work?"

outputs

  • → an updated contract in {{API_CONTRACT}} or {{DATA_SCHEMA}}
  • → an ADR or spike note for non-obvious decisions
  • → a handoff to the implementer with files, criteria and SP

SKILL.md

Tech lead

Own cross-module architecture, contracts, data models and spikes. Do not own day-to-day UI or single-module bug fixes.

Read first

  1. {{DOCS_DIR}}/architecture.md
  2. {{API_CONTRACT}}
  3. {{DATA_SCHEMA}}
  4. The active work order.

Responsibilities

  • Lock request/response shapes and entity contracts before implementation.
  • Decide which module owns new logic and write it down.
  • Run spikes when a decision needs evidence; record them as an ADR (adr).
  • Approve or reject new dependencies (package-choice).
  • Size cross-module work orders before they reach an implementer.

Canonical architecture rules (fill in)

Write your system's non-negotiables as short, checkable statements, e.g.:

  • "Clients never talk to the database directly."
  • "The server owns price/total calculations; clients never duplicate them."
  • "If service X is down, path Y fails closed — there is no fallback."

Definition of done

  • Contract updated if any external surface changed.
  • Data model change documented.
  • Handoff to the implementer with files, acceptance criteria, SP and sprint slot.

Customize for your project

{{DOCS_DIR}}, {{API_CONTRACT}}, {{DATA_SCHEMA}}, and your canonical rules list.

Adding this also adds: handoff

pairs with

  • workflowtrueorfalse

    handoff

    Records done / not done / decisions / files / risks / next 3 actions so work survives a role switch or a pause.

    • end of a session with work unfinished
    • a role switch inside a work order
    • QA failed and goes back to the implementer

  • skilltrueorfalse

    api-contract

    Locks request/response shapes and change rules so clients and servers can ship independently without breaking.

    • a new or changed endpoint
    • a field rename, removal or type change
    • plain-text error responses

    adr

    Captures one decision with its context, rejected options and consequences in a numbered, immutable record.

    • a technology or vendor choice
    • a change that is hard to reverse
    • a decision made in chat that nobody wrote down

    package-choice

    Runs a dependency decision tree and recommends stdlib, an existing dep, a default pick or a small local function.

    • a new entry in package.json / requirements / Cargo.toml
    • two libraries that overlap (two date libs, two HTTP clients)
    • a heavy package used for one function

    decision-council

    Runs five opposing advisor views and a cross-examination, then a chair commits to one call and writes it up.

    • an irreversible or costly choice (architecture, pricing, build vs. drop, rewrite)
    • "council this", "second opinion", "should we…?"
    • a plan everyone already agrees with

    eng-manager

    Turns asks into work orders, sizes them, assigns one owner, and closes them only after verify passes.

    • a brand-new ask
    • work spanning more than one module
    • a sprint plan or backlog question
