Configuration

This page is for repository owners connecting the faff plugin to a tracker or tuning appetite and slots. New adopters should complete Your first runs first. Continue with Skills and slots to replace a worker, or Unattended runs at L3 to prepare an unattended workload.

The minimum configuration is three lines. Other settings have defaults.

Setup​

Works with Linear, GitHub Issues, Jira, or any tracker exposed via MCP. No tracker? It falls back to git-only mode.

Drop a .faffrc.yaml at your repo root telling it where your stuff lives:

tracking:
  tracker: linear        # or github, jira — autodetected if you skip it
  team_key: PROJ
  repo: org/repo

That's the whole minimum. Everything else has a sensible default. (/faff-onboard writes this file for you on a first run — autodetecting what it can.) Copy .faffrc.example.yaml for the full list of knobs.

Linear + GitHub: PR-open automation​

This note is scoped to repositories using Linear's GitHub integration. Linear can auto-link every issue identifier it finds in a PR body and apply a team-level "PR opened → In Progress" rule to each one — including an issue the PR only mentions rather than targets. If you want faff's own explicit claim write (/faff-graft moving an issue to In Progress) to be the sole signal that an issue is claimed, disable that team/workspace automation rule in Linear.

This is a manual, workspace-level trade-off: turning the rule off also removes the convenience for PRs opened by hand, not just faff-driven ones. Linear's merge/link behaviour (closing an issue on merge, showing linked PRs on the issue) is configured separately and does not need to change.

faff renders every non-target issue citation in a PR body with a non-ASCII hyphen regardless of this setting — repository behaviour must not depend on an out-of-band workspace configuration a later operator could quietly flip back on.

Record locations​

Specs, PRDs, PRDRs, ADRs, and spikes default to docs/specs/, docs/prd/, docs/prdr/, docs/adr/, and docs/spikes/. Repositories with another structure can override any location:

tracking:
  spec_docs_path: records/specs/
  prd_docs_path: records/prd/
  prdr_docs_path: records/prdr/
  adr_docs_path: records/adr/
  spike_docs_path: records/spikes/

Paths are relative to the repository root. Existing repositories need no change; the docs/* defaults remain in place.

Appetite​

appetite: high           # low | medium | high | full  (default: high)

Appetite sets how much rope the pipeline gets before it checks back. More isn't always better: it buys speed against the odd "oops, wrong call, revert that." Lower it while you're learning to trust a level; the default suits unattended runs.

Slots​

Slots decide what runs at each stage — a beefier spec, a harsher reviewer, a parallel build. Swapping a slot customises what a level does, not which level you're at. Point a slot at your own or a third-party skill:

slots:
  intake: superpowers:brainstorming   # how /faff-jot runs discovery
  spec: gstack:autoplan               # how /faff-prep writes specs
  review: gstack:review               # pre-PR review
  ship: gstack:land-and-deploy        # merge/deploy

All slots are optional — unset just means "use ours", and a missing slot is never a reason to park. A non-default occupant is automatically checked for conformance before first use — no flag to set. Pre-flight your configured occupants before an unattended run with faff validate-adapters --configured (see CLI).

For per-slot model/provider settings (e.g. running the adversarial reviewer on a different model) and the full catalogue of swappable skills, see Skills & slots.
