The skill

The tend skill writes, edits and refactors Allium specs: adding entities, rules, triggers and surfaces, fixing validation errors and migrating versions, while pushing back on vague requirements.

Only when you ask.

The habit

Spec changes stay valid.

↻ Runs by itselfspec change requested

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

spec change requested. Runs in Claude Code routine.

  • ↻ spec change requested
  • issue labelled spec-change

02

It checks its work

allium check passes. If a check fails, it tries again.

  • ✓allium check passes on every modified .allium file
  • ✓-- allium: N version marker unchanged
  • ✓temporal triggers have requires guards
  • ✓only .allium files changed

03

It remembers

spec change log. The next run reads it first: open questions parked by earlier edits.

loops/allium-tend-loop/log.md

One run, step by step.
Then it stops.

Stop ruleStops after one change request per run and at most two check retries.

  1. 01

    Start up

    Your agent reads the language reference and the relevant .allium files, and runs allium check first.

  2. 02

    Challenge vagueness

    It asks what happens at boundaries, under failure and with concurrency before writing.

  3. 03

    Check the flow

    It looks at data flow, transition graph impact and surface coverage for the new rule.

  4. 04

    Edit minimally

    It adds only what was asked and follows the spec writing guidelines.

  5. 05

    Verify

    It runs allium check after every edit and allium analyse if the spec qualifies.

  6. 06

    Explain

    It states the behavioural intent, shows the changes and logs open questions.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Tend skill helps.

Use it when

  • ✓ adding a rule or entity to a spec
  • ✓ fixing allium check errors
  • ✓ renaming across spec files

Skip it when

  • – building a spec from scratch
  • – extracting a spec from code

Questions

Tend skill, answered.

Does it change application code?

No. It works on .allium files only; code alignment is the weed skill.

What if the request is unclear?

It asks you, or records an open question when no person is reachable.

How do I install the Tend skill?

Copy the prompt at the top into your agent. It installs the skill from juxt/allium and sets up the habit. Or run npx skills add juxt/allium --skill tend.

Is the Tend skill free?

Yes. It is published under MIT. Habit is free too.
