 ### Fixed
 
+- **Plan CLI documentation corrections** (PR #6571): Ensured plan explain and
+  plan tree examples use full 26-character ULIDs and documented `agents plan
+  correct` usage alongside `agents plan explain` for consistent guidance. (#7674)

 - **Validation Gate Empty-Run Guard** (#7508): Fixed `ApplyValidationSummary.all_required_passed`
   returning `True` when zero validations were run, silently bypassing the apply gate. The property
   now returns `False` when the validation result set is empty (`is_empty` is `True`), ensuring

+## `agents plan correct`
+
+Correct a recorded decision by providing updated guidance.
+
+### Synopsis
+
+```bash
+agents plan correct <DECISION_ID> --mode <MODE> [OPTIONS]
+```
+
+`<MODE>` must be either `revert` (re-run from the corrected decision) or `append`
+(add guidance without replaying the tree).
+
+### Options
+
+| Flag                | Description                                                  |
+|---------------------|--------------------------------------------------------------|
+| `--mode MODE`       | Correction mode: `revert` recomputes from the decision; `append` records guidance only |
+| `--guidance`, `-g`  | Guidance text describing the corrected decision               |
+| `--dry-run`         | Preview the correction impact without applying it            |
+| `--yes`, `-y`       | Skip confirmation prompts when replaying corrections         |
+| `--format`, `-f`    | Output format: json, yaml, plain, table, rich                |
+
+### Examples
+
+```bash
+# Revert decision with updated guidance
+agents plan correct 01BRZ4PDFLUTW5SSGR70H6GBW9 --mode revert \
+  --guidance "Prioritize incident triage before refactors"

+# Append guidance without recomputing immediately
