context-engineering skillA

context-engineering is agent-read markdown (skill) from nahid-sparktales/agent-dispatcher: Decide what actually occupies the model's window — progressive disclosure through an index, retrieval versus inlining, what compaction must preserve, and what loading everything costs. Use when a prompt or agent pulls in many files, docs or tool transcripts, when quality decays over a long session, when choosing between fetching at runtime and pasting up front, or when a context has to be trimmed or summarized. Not for the wording of the prompt, not for an agent's job and tool boundaries, and no.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Context engineering

Loading everything is not thoroughness. It buries the instruction that mattered, raises cost on
every turn, and makes the failure look like a model problem instead of a packing problem.

## When this fires

When a prompt, agent or session loads substantial material, or when material has to be dropped.
It does not fire for a short prompt with fixed, small inputs.

## Procedure

1. **Measure before trimming.** List what is loaded each turn and how large each block is, biggest
   first. Trimming by intuition removes the piece that was doing the work. If the runtime gives no
   accounting, approximate it and say the numbers are approximate.
2. **Classify every block by when it is needed.** Always — the task and the output contract.
   Sometimes — loaded when a stated condition holds. On demand — fetched by name only when a step
   calls for it. A block that fits none of these is not needed; drop it and see what breaks.
3. **Build the index that makes disclosure possible.** A short list of what exists, what each thing
   is for, and when it applies — written so the choice can be made without reading the thing
