Explains how Sylph composes PR descriptions — the 4-section template, the fallback ladder when Crow V4 continuity or W2 cluster data is missing, and how to override the default template via PULL_REQUEST_TEMPLATE.md.

Surfaces the decision-gate to the user when a destructive git operation is detected, pausing the session for explicit confirmation before the command runs. Invoked by sylph-gate's PreToolUse hook when a Bash call is classified destructive or protected-destructive.
Explains how W2 Jaccard-Cosine Boundary Segmentation works, what events fire it, and how to interpret the cluster state in plugins/boundary-segmenter/state/boundary-clusters.json. Invoked when a developer asks "why did Sylph commit/branch here?" or "what's W2 doing?"
Explains how W4 Path-History Reviewer Routing ranks candidate reviewers — recency-weighted blame, path-depth specificity, CODEOWNERS boost, and optional Crow reviewer-availability filtering. Helpful when a developer asks "why did Sylph suggest these reviewers?"
Explains the W3 decision tree — how Sylph chooses between GitHub Flow, Trunk-Based, GitFlow, Release Flow, Stacked Diffs, and Unknown. Helpful when a developer asks "why did Sylph pick this branch name?" or wants to override detection via .sylph/workflow-map.yaml.

## What changed — commit subjects, with short SHAs
## Why — session intent (Crow V4) or inferred from commits
## How it was verified — observed test runs, or "inspection only"
## Rollback plan — `git revert --no-commit <shas>` template
Sylph produces the best description it can from whatever signals are present:
/sylph:pr aborts with a hint to commit first.If the repo has a GitHub .github/PULL_REQUEST_TEMPLATE.md, Sylph honors
it by appending the four Sylph sections below the template. Developers
who want Sylph's sections to replace the template should delete the
template file; developers who want Sylph to defer entirely can set:
# .sylph/config.yaml
pr_description:
mode: template-only # "template-only" | "append" (default) | "sylph-only"
[Not yet implemented — roadmap.]
The pr-description-crafter agent is Opus-tier. Each PR open costs ~1 Opus
call (typically 2k-6k input tokens, 500-1500 output). If Pech signals
budget pressure via pech.budget.threshold.crossed, Sylph degrades to
Sonnet (produces a serviceable but terser description) and tags the PR
body with a *(budget-degraded)* marker.
