Refresh

Summaries refresh (headless)

A consumer repo commits a render script whose output lines carry — suffixes read from a JSON sidecar via this plugin's summaries.py module; this skill is the scheduled Claude pass that owns the words — it rewrites that sidecar from real data, then re-renders. The mechanics (staleness gate, sanitizing, key matching) live in the module; the per-repo specifics (which groups, where the raw material comes from, how to re-render) live in the repo's config. Non-interactive by design — never ask questions, never wait for confirmation; if a step can't proceed, print why and stop.

What consumers commit (one-time setup)

• summaries.py — copy

${CLAUDE_PLUGIN_ROOT}/skills/refresh/templates/scripts/summaries.py next to the render script, which imports load_summaries / summary_for (plus SUMMARY_STALE_DAYS / SUMMARY_MAX_LEN, summaries_fresh, clean_summary, parse_iso as needed). The render script only ever reads the sidecar; this skill is the only writer.

• .github/summaries.config.json — the config below.

The config

{
  "sidecar": ".github/profile-summaries.json",  // sidecar path, repo-root-relative
  "style_file": null,                           // optional path; its rules WIN over the style core below
  "stale_days": 10,                             // freshness window; must match what the render script passes
  "render_command": "python3 .github/scripts/update_profile.py update",  // run after the sidecar is written
  "groups": {                                   // one entry per sidecar group
    "": {
      "description": "what one entry of this group summarizes",
      "key_hint": "how keys are formed, with an example",
      "as_of_hint": "the reuse token recorded per entry, or 'none' for immutable keys",
      "raw_material": "prose instructions — gh api recipes — for gathering what summaries are built from"
    }
  }
}

sidecar, render_command, and groups are required; style_file defaults to null and stale_days to 10.

Work the steps in order.

1 — Resolve the config

Read .github/summaries.config.json in the repo being refreshed — or the config path the invoking skill named. Config missing, or missing one of sidecar / render_command / groups → print what and stop; this skill never invents per-repo specifics. If style_file is set, read it now: its rules override the style core in step 4.

2 — Read the current sidecar

Read the config's sidecar file, if present — entries you can prove unchanged get reused, not rewritten.

3 — Gather raw material

Per group, follow the config's raw_material instructions to fetch what the summaries will be built from (keep it to ~15 gh api calls across all groups). The raw material is the entire universe of facts: nothing a summary says may come from anywhere else.

4 — Write the sidecar

Rewrite the sidecar whole — regeneration is pruning; never merge. Schema:

{
  "version": 1,
  "generated_at": "",          // bump EVERY run, even if no entry changed
  "": {
    "": {"as_of": "", "summary": "..."}
  }
}

Rules, non-negotiable (the config's style_file may override the style core only):

• Keys come from the current raw material only, formed per the group's

key_hint. Keys absent from the current data don't get entries — that's the pruning.

• Reuse before rewriting: an existing entry whose key and as_of (per

the group's as_of_hint) still match is kept verbatim.

• Style core: each summary is a lowercase continuation clause — it

renders after — on an already-verbed line — ≤ 80 chars, no trailing period, no emoji, no first person. Concrete and artifact-shaped: "built the realtime inline-comment web UI", not "made improvements".

• Flattery law: every word traces to the gathered raw material (commit

subjects, PR/issue titles, release content, ...). Never invent, never editorialize beyond what the material says. When the raw material is uninformative ("wip", "bump deps", "fix typo"), omit the entry — a plain line beats a fake summary.

• Deterministic bytes: sorted keys, 2-space indent, trailing newline.

5 — Re-render

Run the config's render_command. A nonzero exit means the consumer's render is broken — stop and report; never patch the consumer's files from this skill.

6 — Hand off or commit

Invoked by a wrapper skill (e.g. /gh-profile:refresh): you're done — the wrapper owns its repo-specific steps and the commit. Invoked standalone:

git add  
git commit -m "chore: refresh summaries"
git pull --rebase && git push

If the push rejects or the rebase touches the rendered files, re-run step 5 once and push again.
