A structured-summary helper with three modes: decisions, operations, and SOC, meaning a record of ongoing stream-of-consciousness work. It summarizes only the supplied information and follows a mode-specific format.

Use it to record decisions and their rationale, document actions and system changes, or capture an SOC record when explicitly requested.

It turns discussions or activity records into concise notes while preserving outcomes, reasoning, evidence, and important missing information.

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	$0.00079	$0.00913
Opus 5	$0.00039	$0.00456
Sonnet 5	$0.00016	$0.00183
Haiku 4.5	$0.00008	$0.00091

Security

Grade A, and why

summarize 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 7d ago.

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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Overview

Produce a concise, structured summary using the canonical protocol for the selected mode. Preserve outcomes, reasoning, and evidence without adding external knowledge.

Mode selection

Select the mode in this order:

If the user explicitly specifies a mode, follow it.
If the user uses Enter SOC or End SOC, use soc mode.
If the request centers on decisions, rationale, or alternatives, use decisions mode.
If the request centers on actions taken, system changes, or outcomes, use operations mode.
If multiple modes plausibly apply, ask the minimum clarification question: "Which mode: decisions, operations, or soc?"

Common rules

Base the summary only on the provided input record.
Do not add external facts, assumptions, or inferred details.
Call out missing or ambiguous information explicitly.
Preserve sequence when the order of events matters.
Keep the output concise and non-narrative.

Mode: decisions

Follow the Summarize Decisions Protocol.

Required section order: Results, Reasoning, Options Not Chosen.
Label implicitly converged decisions as implicit.
Include optional sections only when present in the input.

Mode: operations

Follow the Summarize Operations Protocol.

Required section order: Actions Taken, Outcomes and Status, Problems Encountered and Solved, Problems Unresolved, Changes and Artifacts, Follow-up Work and New Issues.
Capture evidence for command-driven actions (commands + minimal output).
Include timestamps when available; state when none were provided.
Redact secrets or sensitive data and note the redaction.

Mode: soc

Follow the Summarize Stream of Consciousness Protocol.

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.

summarize is a skill published in the GitHub repository vergil-project/vergil-claude-plugin (2 stars, last pushed 5d ago), licensed MIT. It adds 79 tokens to every session and 913 once invoked, about $0.0004 per session on Opus 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 2026-08-31.
