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
-
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.
-
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.
-
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".
-
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.py11:05 — narrowed cause to driver init order11:30 — 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:
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.
