Speckit Opsmill Summary

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Supported argument: --since <commit|time> to bound the summary window. Examples:

• --since HEAD~10 — limit the timeline to phases that began after the 10th-most-recent commit on this branch.
• --since 14:00 — only include phases that occurred after 2 PM local time in the active session.

If no argument is given, summarize the entire live session.

Goal

Produce a single markdown document that lets a teammate (or future-you) understand the flow of the session in under 60 seconds. The unit of output is the working session, not any one artifact. Different granularity from speckit.archive (per-feature, permanent) and speckit.reconcile.run (drift-fixing).

Operating Constraints

STAY AT THE FLOW LEVEL. This summary is a narrative, not a transcript. Do NOT include any of the following:

• Per-tool-call narration ("called Read on X.py, then called Edit on...")
• Diffs or hunks of any size
• Line numbers
• Code snippets longer than a single line
• File-by-file change logs (those belong in PR descriptions and git log)
• Step-by-step reproductions of debugging
• Quotes from the conversation buffer longer than one short clause

STRICTLY ADDITIVE. Do not modify spec.md, plan.md, tasks.md, or any source files. The only file this command writes is the session summary itself.

IDEMPOTENT IN SPIRIT. A second invocation in the same session must produce a comparable summary, not a summary of summaries. Ignore previously generated session files when composing the new one.

Outline

1. Run .specify/scripts/bash/check-prerequisites.sh --json --paths-only from repo root and parse FEATURE_DIR from the JSON output. All paths must be absolute.

   • If FEATURE_DIR is missing, empty, or the resolved directory does not exist, fail fast with a clear error such as: No feature directory resolved from current branch — /speckit.opsmill.summary requires an active feature branch. Suggest the user switch to a feature branch and re-run.

2. Parse $ARGUMENTS for an optional --since <value>. Treat the value as opaque — pass it through to git log --since=<value> if it parses as a date/time, otherwise treat it as a git revision and use git log <value>..HEAD. Do not attempt to interpret it any further.

3. Gather context for the summary, in this order of preference:

   a. The live conversation context (primary source — the actual session is what is being summarized). b. git log on the current branch, optionally bounded by --since, for outcomes that already landed as commits. c. FEATURE_DIR/spec.md, plan.md, tasks.md if they exist — only to anchor terminology, not to copy content.

   Do not read every changed file. Do not generate diffs. Stay at the level of "what phase of work was happening, and what did it produce".

4. Compose the summary with exactly these three sections, in this order:

   Executive Summary

   One paragraph (2–4 sentences). What was this session about? What was the working theme? Reading just this paragraph should answer "what did they spend their time on today?".

   Timeline

   A chronological bullet list. Each entry is a single short line in the form HH:MM — <human-readable phase>, e.g.:

   • 10:42 — investigated failing E2E test in deployments_create.py
   • 11:05 — narrowed cause to driver init order
   • 11:30 — applied fix and re-ran suite

   Aim for 5–15 entries. Collapse near-duplicate phases (e.g. three consecutive "ran tests" lines into one). If exact timestamps are not recoverable, use relative ordering with no HH:MM prefix and a leading dash only.

   Outcomes

   A short bullet list of concrete results from the session. Reference paths and PRs only — no diffs. Examples:

   • Opened PR #161 (speckit-extensions cleanup).
   • Materially changed .specify/extensions/auto/, tinyspec/.
   • Decided: extensions invoke skills, not slash commands.
   • Deferred: rewriting the auto extension's hook condition DSL.

5. Write the file.

   • Path: FEATURE_DIR/sessions/session-YYYY-MM-DD-HHMM.md, where YYYY-MM-DD-HHMM is the local time at invocation.
   • Create FEATURE_DIR/sessions/ if it does not exist.
   • If a file with the same HHMM already exists, append a numeric suffix (-2, -3, …) rather than overwriting.

6. Print the resolved path back to the user as the final message, plus a one-line reminder that the summary is intentionally high-level and the conversation transcript / git log remain the sources of truth for detail.

Quality Bar

A reader who was not in the session should, after under 60 seconds with the document, be able to answer:

• What was the session trying to accomplish?
• What was the rough order of work?
• What concretely shipped, what was decided, what was deferred?

If the draft cannot pass that bar, tighten it before writing. If it exceeds ~80 lines of markdown, you are too detailed — cut.
