Skill: /platform-bottleneck

Alias. Delegates to /bottleneck-pick --layer platform.

Decision (S-46, 2026-05-21): two skills (intra + platform) merged into one via the --layer parameter. A separate skill is redundant. Kept as a convenience trigger.

SC: DP.SC.152. Owner: DP.ROLE.054.

Algorithm

Step 1. Parse arguments

Extract --horizon, --subsystem, and the optional --systems-map <path> from the call arguments. The map path is user data and is not part of the public Template.

Step 2. Verify the systems map

Before delegating, determine the root of the installed workspace (WS="${IWE_WORKSPACE:-$PWD}") and load its .iwe-paths: . "$WS/.iwe-paths". If the file is missing or IWE_TEMPLATE/IWE_WORKSPACE are empty — report that path setup is incomplete and stop. The Script lives in the nested Template, not in workspace/scripts: run bash "$IWE_TEMPLATE/scripts/check-platform-systems-map.sh"; if --systems-map is provided, append --map "<path>". Exit code 2: pass the script's diagnostic output to the user and stop — do not build analysis on an incomplete map. A successful call prints the verified path from the workspace; pass exactly that path to the next step as a single argument.

Step 3. Delegate to /bottleneck-pick

Without --subsystem:

/bottleneck-pick --target c2:platform --layer platform --systems-map "<verified_path>" [--horizon <h>]

With --subsystem:

/bottleneck-pick --target c2:platform --layer platform --subsystem <s> --systems-map "<verified_path>" [--horizon <h>]

Step 4. Return the result

The result of /bottleneck-pick is passed to the pilot without modification.
