What is gather-retrospectives?

A tool for collecting feedback from earlier coding-agent sessions about a package, tool, or workflow. A retrospective is a review of past work used to find recurring problems and friction.

Use it to review past sessions, investigate repeated workflow problems, and gather retrospective feedback for a project or tool.

It prevents conclusions from being based only on the current session. It gathers historical reports within a selected workspace and preserves the evidence while it is being read.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.01215
Opus 5.5	$0.00015	$0.00486
Sonnet 5.5	$0.00008	$0.00243
Haiku 4.5	$0.00004	$0.00121

Security

Grade A, and why

gather-retrospectives scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/collect.mjs, scripts/snapshot.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Gather retrospectives

Collect once

Default to the current workspace tree and all dates. Other projects and sibling worktrees require user-approved scope. A topic (“about supi-agent”) is not a producer filter: keep both sources unless asked for delegated runs (--source supi-agent) or Reviewer Runs (--source supi-review).

Resolve the script relative to this skill directory and run directly:

output_dir=$(mktemp -d)
node "<absolute-skill-directory>/scripts/collect.mjs" \
  --workspace "$PWD" --output "$output_dir/evidence.json"

The command is ready to execute. See CLI flags for scope, date, storage, scan-limit, and display options. If execution is unavailable, report that limitation.

Read to completion

The temporary evidenceFile freezes all matching reports and scan coverage. Stdout supplies assessment text and citations within 16 KB. Use the displayed text directly, then execute nextCommand until display.complete is true. These follow-ups read the snapshot, not session storage, so new sessions cannot shift the results. Oversized assessments continue under the same ref with contiguous UTF-16 textRange offsets; interpret their fragments together.

coverage.complete describes the scan independently of display completion. Disclose scan limits, malformed entries, skipped symlinks, or read failures when false.
summary counts the entire deduplicated snapshot: reports by producer/status, containing sessions, and earliest/latest report dates. Reports from one session remain correlated.
If a user requests a bounded sample, stop at that bound and disclose unread reports rather than claiming exhaustive coverage.
No matching reports: report the empty result and coverage limitations in at most 100 words, link the evidence, and finish. Optional capture and successful-task selection mean absence of feedback is not absence of regressions.

For a later targeted reread, select references without rescanning:

node "<absolute-skill-directory>/scripts/collect.mjs" \
  --read "/absolute/evidence.json" --refs "R-<id>,R-<id>"

What ships with it

11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gather-retrospectives is a skill published in the GitHub repository mrclrchtr/supi (103 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 1,215 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-27.
