# Terraform Plan Context > Use when analyzing Terraform plan files or reviewing Terraform infrastructure changes. Converts plans into compact agent-readable context with tfplanctx. - Skill: `tomevault-io/terraform-plan-context` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/terraform-plan-context` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/terraform-plan-context/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: DevOps & Infra - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/terraform-plan-context --- Prefer `tpc` before raw Terraform JSON or human plan output. Workflow: 1. `tpc --summary` 2. `tpc --risk-only` 3. `tpc --budget 4000` 4. `tpc --resource
` for one resource 5. `tpc --detail` only when review mode is insufficient Read TFP2 like this: - Header: `TFP2 C U R D Q OUT RISK DRIFT [OMITTED]` - Actions: `C` create, `U` update, `R` replace, `D` delete, `Q` read, `O` output - Resource row: `|
||` - Create shows after values only; delete shows before values only; update/replace uses `before->after` - Paths use dot notation and `[n]`; delimiters are percent-escaped - Key metadata: `unk`, `sens`, `repl`, `why`, `risk`, `def`, `comp`, `summ`, `omit` - `O|...` rows are output changes - `G|...` plus `|...` rows, `GL|...`, and `L|IAM|...` are compressed resource forms; expand `refs`, inherited common fields, and metadata before reasoning - `TPL|P...` defines address prefixes; `$P...` expands addresses - `VAL|V...` defines repeated values; `$V...` expands exact values - `REASON_CODES|...` expands short `why=` codes - `OMIT|...` is lossy review summarization; `COMPRESS|...` is non-lossy factoring - `DRIFT|...` / `DRIFT_GROUP|...` summarize low-signal drift; detailed drift remains explicit - `MIGRATION?|...` is a structural hint, not Terraform proof If `OMITTED`, `summ`, or `detail_required=true` matters to the task, use `--detail`. Avoid raw `terraform show -json` unless `tpc` is insufficient. Never apply Terraform changes unless the user explicitly asks. --- > Source: [pibblokto/tfplanctx](https://github.com/pibblokto/tfplanctx) — distributed by [TomeVault](https://tomevault.io).
