Indexion SDD

by trkbt10 · 5K installs

The skill

Indexion sdd drafts spec-driven development requirements from RFCs and standards, then measures how well the implementation conforms with spec align and spec verify, including CI drift gates and a codex or claude validation loop.

Only when you ask.

The habit

Implementation stays aligned with the spec.

↻ Runs by itselfpull request opened

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

pull request opened. Runs in GitHub Actions.

  • ↻ pull request opened
  • pull_request paths: src/**, .kiro/specs/**

02

It checks its work

spec align gate. If a check fails, it tells you.

  • ✓indexion spec align status --fail-on any --threshold 0.3 exits 0
  • ✓Shallow count is 0
  • ✓E2E tests on real input pass

03

It remembers

SDD reports folder. The next run reads it first: the last align-diff and verify-gaps reports.

.indexion/sdd-reports/

One run, step by step.
Then it stops.

Stop ruleStops after one gate run per pull request, with no retries.

  1. 01

    Check the tool

    Run indexion --version and indexion kgf edges on a source file to confirm the gate can run.

  2. 02

    Report gaps

    Run indexion spec verify and indexion spec align diff with --threshold 0.3 and save them to .indexion/sdd-reports/.

  3. 03

    Run the gate

    Run indexion spec align status with --fail-on any against src/.

  4. 04

    Run E2E tests

    Run the end-to-end tests on real input, since vocabulary alignment cannot prove the code works.

  5. 05

    Suggest fixes

    On failure, run spec align suggest and post the DRIFTED, SPEC_ONLY and SHALLOW items to the PR summary.

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 Indexion SDD skill helps.

Use it when

  • ✓ You implement an RFC as a library
  • ✓ You gate merges on spec conformance
  • ✓ You run cc-sdd with codex or claude

Skip it when

  • – You have no written specification
  • – Your project does not use indexion

Questions

Indexion SDD skill, answered.

Why a threshold of 0.3?

The skill says the default 0.6 is too high for short acceptance criteria matched against code and doc comments.

What does SHALLOW mean?

A requirement matched only type definitions in a file with no non-trivial functions; add logic to the same file.

Does passing the gate mean the code is correct?

No. It checks vocabulary only, which is why E2E tests on real input are part of the check.
