lh-tradeoffs SKILL.md skillA
lh-tradeoffs from jrodrigopuca/local-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jrodrigopuca/local-agents/lh-tradeoffs@v1.1Pins v1.1 in mdr.lock. Pin the fingerprint instead.

Method for analyzing and presenting expensive-to-reverse technical decisions: drivers, options, tradeoff table, recommendation, ADR shape. Trigger: load when a decision is costly to change later (data model, service boundaries, framework, sync/async, build-vs-buy), when the user asks "should we use X or Y", or when a project decision needs recording or an existing one is being reopened.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Critical Patterns
### 1. Reversibility check first
Before any analysis: **how expensive is this to undo?** If it's cheap (rename,
internal refactor, swappable lib behind an interface), say so, give a fast
recommendation, and don't burn the user's time on ceremony. Full analysis is for
one-way doors.
### 2. Drivers before options
Extract the real drivers before comparing anything. Ask (or infer from context)
in this order:
1. **Scale & load** — actual numbers, not aspirations ("we'll be huge" is not a driver)
2. **Team** — size, seniority, what they already operate well
3. **Rate of change** — which parts of the system change weekly vs yearly
4. **Consistency & failure tolerance** — what breaks, and who cares, when it's stale or down
5. **Data shape** — when an option splits, copies or reshapes persisted data,
its cost is a cardinality, a lock window or a lost constraint, not an
adjective; that number comes from [dba](../../../dba/AGENTS.md), and an
option priced without it is priced wrong
6. **Deadline & budget reality**
A comparison without drivers produces the generic blog-post answer. The drivers
ARE the analysis; the table is just its display.

How to install
mdr add jrodrigopuca/local-agents/lh-tradeoffs@sha256:2d48bcc44908e285The line at the top of this page pins the label v1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
