invokta: Skill for Codex

.agents/skills/invokta-delivery/SKILL.md

invokta-delivery is a skill for Codex from vinilana/invokta. It costs 57 tokens per session (710 once invoked), scanned A, original, MIT.

A development procedure for the Invokta software project. It uses TDD, meaning tests are written to describe expected behavior before the implementation is completed.

In plain words
What is it for?
Building features, fixing bugs, completing roadmap milestones, and meeting documented acceptance criteria in Invokta.
Why use it?
It helps keep new work aligned with the project's documented contracts and architecture. It also requires validation and keeps each work item as one focused commit.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents); $skill-name invocation.

This is vinilana/invokta's own configuration. It tells Codex how to work on invokta itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything invokta configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

invokta-delivery scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Invokta Delivery

Prepare the delivery

  1. Read docs/README.md and locate the milestone in docs/implementation-plan-and-acceptance-criteria.md.
  2. Compare the milestone with docs/vision-and-invariants.md, docs/architecture.md, docs/scope-and-limits.md, docs/adr/README.md, applicable ADRs, public contracts, and acceptance tests. Treat these sources as authoritative; do not duplicate their detail in this skill.
  3. Inspect the code, tests, and Git state before editing. Preserve unrelated changes and exclude unrelated files from the work item.
  4. Define a small vertical slice: observable behavior, acceptance criterion, affected components, and validation command.

Stop and request a decision when authoritative documents conflict, acceptance criteria are not testable, or implementation requires expanding the contract or architecture.

Apply the gates

Gate 1 — Scope and contract

  • Map each acceptance criterion to at least one observable test.
  • Confirm inputs, outputs, errors, invariants, and limits before changing the implementation.
  • Preserve public contract compatibility. Require an explicit decision for any breaking change.
  • Apply $invokta-contract-review before coding when the milestone creates or changes an API, schema, port, event, public error, or operational limit.

Gate 2 — RED

  • Write the smallest test that demonstrates the missing behavior or bug first.
  • Run the test and confirm that it fails for the expected reason, not because of an environment, fixture, or syntax error.
  • Record the RED evidence in the delivery summary.

Do not proceed without a valid RED result unless the change is strictly documentation or tooling with no executable behavior. Explain the exception.

Gate 3 — GREEN and REFACTOR

  • Implement only what the test and contract require.
  • Follow the dependency direction, ports, adapters, and boundaries defined by the ADRs.
  • Avoid architectural shortcuts, global dependencies, validation bypasses, and premature abstractions.
  • Run the focused test until it passes. Refactor without changing behavior, then run it again.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
