Finops

If multiple resource types are found, run the matching sub-skills in sequence.

If no matching sub-skill exists for a detected resource type, note it in the report as "not yet supported" and continue with the types that are supported.

Step 3 — Delegate to Sub-skill(s)

Each sub-skill always writes to fixed filenames (findings.json, parsed_input.json, finops_report.md, main_optimized.tf). The orchestrator must snapshot these files between sub-skill runs to prevent overwriting.

Per sub-skill execution loop

For each matched sub-skill <SKILL> (e.g. elb, rds):

a. Execute the sub-skill by reading and following its SKILL.md at .claude/skills/finops-<SKILL>/SKILL.md. Pass the same WORK_DIR and input file paths.

b. After it completes, use the Bash tool to snapshot its output files:

cp WORK_DIR/findings.json       WORK_DIR/findings_<SKILL>.json
cp WORK_DIR/parsed_input.json   WORK_DIR/parsed_input_<SKILL>.json
cp WORK_DIR/finops_report.md    WORK_DIR/finops_report_<SKILL>.md
# main_optimized.tf is written by the agent (Write tool), not the scripts —
# read it and remember its content for the merge step, or copy:
cp WORK_DIR/main_optimized.tf   WORK_DIR/main_optimized_<SKILL>.tf

Proceed to the next sub-skill. The next sub-skill will overwrite the base filenames, which is expected — the snapshots preserve each skill's output.

Step 4 — Summarize and Merge

If only ONE sub-skill ran: the base output files (finops_report.md, main_optimized.tf) are already the final combined outputs. No merge needed.

If MORE THAN ONE sub-skill ran, produce merged final outputs using the Write tool:

4a. Merge WORK_DIR/finops_report.md

Read each finops_report_<SKILL>.md in order. Write a single WORK_DIR/finops_report.md that:

1. Combined header:

   # FinOps Combined Analysis Report
   - Sub-skills run: finops-elb, finops-rds, ...
   - Total resources checked: N
   - Total issues found: N
   

2. Each sub-skill's full report content under its own heading:

   ## ELB Analysis (finops-elb)
   <full content of finops_report_elb.md>
   
   ## RDS Analysis (finops-rds)
   <full content of finops_report_rds.md>
   

3. Unified savings table at the bottom:

   ## Total Savings Summary
   | Sub-skill  | Issues | Monthly Savings | Annual Savings |
   |------------|--------|-----------------|----------------|
   | finops-elb | N      | $X              | $Y             |
   | finops-rds | N      | $X              | $Y             |
   | **TOTAL**  | **N**  | **$X**          | **$Y**         |
   

4b. Merge WORK_DIR/main_optimized.tf

Read each main_optimized_<SKILL>.tf in order. Write a single WORK_DIR/main_optimized.tf that:

1. Shared terraform {} and provider "aws" {} blocks — included once (from any sub-skill)
2. Each sub-skill's resource blocks in sequence, preceded by a section comment:

   # ══════════════════════════════════════════
   # ELB changes — finops-elb
   # ══════════════════════════════════════════
   <resource blocks from main_optimized_elb.tf>
   
   # ══════════════════════════════════════════
   # RDS changes — finops-rds
   # ══════════════════════════════════════════
   <resource blocks from main_optimized_rds.tf>
