What it does

Routine Abstraction Improver is an agent skill from bex-co/beancount-io. Autonomous maintenance routine that flattens over-engineered abstractions in a monorepo package — interfaces with one implementation and no stated reason, passthrough wrappers, one-product factories, delegate-only manager layers — by inlining the single thing behind them and shipping via /ship. Use only when the user explicitly invokes /routine-abstraction-improver or asks to flatten needless indirection. SKIP for convoluted logic inside one unit (routine-logic-simplifier), imports crossing stated boundaries…

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Monorepo tooling. The repository describes itself as: 💰 Double-entry bookkeeping made easy — plain-text accounting for humans and AI agents. Polished iOS & Android app built with React Native + Expo. The licence is MIT.

When your agent uses it

  • Explicitly invokes /routine-abstraction-improver
  • Asks to flatten needless indirection
  • Is remove indirection that has exactly one thing behind it

Example prompts

  • “remove indirection that has exactly one thing behind it”
  • “/routine-abstraction-improver”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Scope
  2. Discover
  3. Prove it
  4. Fix
  5. Verify
  6. Ship

What it can do on your machine

Read from SKILL.md and the folder at commit 2103ca1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Routine Abstraction Improver loads about 810 tokens when it runs. Until then it costs about 176 tokens; SKILL.md has 336 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~176
When it runs · the whole SKILL.md, loaded when a task matches
~810

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Autonomous maintenance routine that flattens over-engineered abstractions in a monorepo package — interfaces with one implementation and no stated reason, passthrough wrappers, one-product factories, delegate-only manager layers — by inlining the single thing behind them and shipping via /ship. Use only when the user explicitly invokes /routine-abstraction-improver or asks to flatten needless indirection. SKIP for convoluted logic inside one unit (routine-logic-simplifier), imports crossing stated boundaries (routine-abstraction-police), and duplicated implementations (routine-dup-unifier). The core trigger is "remove indirection that has exactly one thing behind it".

Task: Flatten over-engineered abstractions

Usage: /routine-abstraction-improver [package-or-path]

Find a layer of indirection with exactly one thing behind it and no stated reason to exist, inline it, delete the layer, and ship via /ship.

Contract

Read .agents/skills/routine-shared/contract.md first — preconditions, scope resolution, verify gates, ship protocol, budget, universal STOPs. Floor even without it: never ship red; one finding per ship; anything in a DO_NOT_DO.md is a hard STOP.

Workflow

1. Scope

Resolve scope per the contract.

2. Discover

The shapes worth suspecting:

  • Interfaces/abstract classes with exactly one implementation
  • Wrapper functions/modules that only re-export or forward arguments
  • Factories that can only ever produce one product
  • Generics never instantiated with a second type
  • "Manager"/"provider"/"service" layers that purely delegate
3. Prove it

A layer is a finding only when all hold:

  1. Grep confirms exactly one implementation and one usage pattern.
  2. No stated reason for it exists. Check the scoped AGENTS.md, docs/adrs/, and .pm boards. In particular: backend-v2 mandates an I<Name> interface beside every service/workflow class (backend-cluster/backend-v2/AGENTS.md, Dependency and layer rules) — those interfaces are a stated convention, never a finding. Same for seams that exist so tests can double them, when the tests actually do.
  3. No evidence of a planned second implementation.
4. Fix

Inline the single thing, delete the layer, call directly. If tests mocked the deleted layer, rewrite them against the concrete unit with real assertions — never leave them asserting a mock of something that no longer exists. Behavior identical.

5. Verify

Typecheck + full owning-package gate, and a grep confirming no dangling references to the deleted layer.

6. Ship

Compose /ship for this one flattening. Loop within budget.

What NOT to do

  • Never flatten an abstraction a AGENTS.md, ADR, or working test double justifies — a stated convention beats this routine's taste, every time.
  • Don't rewrite convoluted logic inside a unit (routine-logic-simplifier) or move code across layers (routine-abstraction-police).
  • Don't flatten two layers in one ship; each deletion stands alone.
  • Don't replace the deleted abstraction with a cleverer one — the fix is less structure, not different structure.
