Claude Code Skills Stack
Installing every shiny skill pack is not a workflow. It is a haunted attic with autocomplete.
The stable stack is three layers: decision, context, and execution. Give each layer one clear job or the session turns into token confetti.
The Take
Use opinionated planning skills to decide what should happen. Use a small context system to keep state from rotting. Use execution skills to write, test, review, and close the loop.
Do not let all three layers talk at once on every task. That is how a two-line patch becomes a committee meeting.
Default Stack
| Layer | Job | Keep | Do Not Let It Become |
|---|---|---|---|
| Decision | Scope, tradeoffs, sequencing | one or two high-value planning skills | a permanent board of directors |
| Context | Goals, constraints, state, open questions | small durable files and summaries | a second codebase made of stale notes |
| Execution | Implementation, tests, verification, closeout | the strongest build-and-check loop | an excuse to skip judgment |
Routing Rule
Route by task shape, not by framework fandom.
- fuzzy requirement - run decision skills first
- long-running feature or multi-session work - update context before more coding
- clear scoped change - go straight to execution
- tiny fix - skip half the ceremony and ship the patch
Why This Structure Holds Up
The late-2025 to early-2026 research is not subtle about it.
- December 18, 2025: PAACE showed plan-aware context compression can improve correctness while cutting context load. Context quality matters more than context bulk.
- December 20, 2025: SWE-EVO showed software evolution tasks stay hard because agents still struggle with long-horizon, multi-file work in realistic repositories.
- January 8, 2026: IDE-Bench argued that real engineering work is collaborative, iterative, and tool-heavy, which is exactly where sloppy skill piles start wasting time.
- February 4, 2026: OmniCode showed agents that look decent on narrow patch benchmarks still fall apart across broader software tasks like test generation and review fixing.
- March 15, 2026: SWE-Skills-Bench found that most software-engineering skills had no measurable value and a lot of them imposed heavy token overhead. More skills was usually just more billable confusion.
Practical Policy
- Pick one execution stack and make it the default.
- Add one decision layer only for work that is still under-specified.
- Keep context artifacts short enough to survive rereading.
- Retire overlapping skills. Duplicate roles are just prompt inflation wearing a fake mustache.
- Review token cost the same way review time gets reviewed. Waste is still waste when it looks intelligent.
Minimal Operating Shape
1. decide:
- clarify goal
- reject bad scope
- lock success criteria
2. stabilize context:
- project summary
- active constraints
- current decision log
3. execute:
- implement
- test
- review
- verify
4. compress:
- write back only what future work needsWhat to Steal From the Current Claude Code Discourse
The April 6, 2026 DEV article on combining Superpowers, gstack, and GSD got the broad framing right: decision, context, and execution are different jobs.
The stricter version here is simpler: keep the layer split, but stop pretending every task deserves the full stack. Most do not.
One decision layer, one context layer, one execution layer. Anything beyond that needs to earn its keep or get cut.
