# Hope Diff

+ Use only when the person invokes `$hope:diff`, `/hope:diff`, or the

+ host's equivalent skill command or picker. Continue follow-ups within that

+ invoked task without requiring another invocation. Ordinary requests and calls

+ from another skill do not activate this skill; continue authorized work through

+ the ordinary workflow. Reading a shared reference does not invoke its skill.

Resolve one exact GitHub pull request, analyze its captured evidence, and

report its artifact. Diff covers the captured PR snapshot; local staged,

unstaged, and untracked changes are outside its scope.

## Resolve the request

Answer a narrow question directly without starting the artifact workflow.

An explicit explanation or review request authorizes the run. Honor existing

authorization and display choices without asking again. A bare target without

a clear task needs clarification, not an automatic full review.

Use `resolve-target [GitHub PR URL or PR number]` to resolve the target before

asking any needed question. Name the repository and PR number. If resolution

fails, ask for a URL or number. Once selected, pass that exact target; do not

fall back to automatic discovery.

Run adapter commands with `node "<skill-dir>/scripts/cli.mjs"`, replacing

`<skill-dir>` with the absolute directory containing this file. In Claude Code

it is `${CLAUDE_PLUGIN_ROOT}/skills/diff`. Pass arguments separately; never

construct shell commands from PR content.

## Analyze the captured evidence

For artifact generation, read `references/workflow.md`, `references/analysis.md`, and

`../write/references/writing-standard.md`. Follow the run from `prepare` through

`finish` or `cancel`, grounding conclusions in the captured evidence.

Use an independent worker when its perspective is worth the time or the person

requests one. Give it a fresh context with the exact request, target, choices,

constraints, and Skill path, separate from earlier conclusions. Disclose any

limit on requested independence. The same evidence and runtime rules apply

whether analysis stays in this conversation or is delegated.

Review generation uses the active host under its data policy; do not claim

private PR content stays on the local machine.

## Return the artifact

Report the PR, exact head, result scope, absolute HTML path, and any failure or

cleanup limit. The artifact completes Diff. The surrounding task handles any

publishing, merging, commenting, or code changes under the person's existing

authorization.

Maintainers changing the runtime read `references/runtime.md` for its

deterministic security and publication contract.
