decision-capture

decision-capture is a skill for Claude Code, Codex from bartoszarendt/agenticloop. It costs 78 tokens per session (1,815 once invoked), scanned A, original, MIT.

A procedure for recording durable project decisions in tracked Markdown files. A durable decision is a choice that constrains future work, such as an architecture, security, process, release, or quality rule.

In plain words
What is it for?
Use it to create, update, accept, or supersede decision records under .agenticloop/decisions/. It also covers promoting recurring verification observations into project-level policy.
Why use it?
Important decisions can otherwise remain hidden in conversations or be rediscovered repeatedly. A shared decision record lets later agents see which choices are proposed, accepted, or replaced.

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.

Security

Grade A, and why

decision-capture 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 4d 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.

Decision capture

Decision records are the small docs-first layer for durable project decisions. They are broader than the narrow ADR threshold. If a decision constrains future work and later agents would benefit from seeing it, it can earn a decision record even when it is not especially surprising or hard to reverse.

When to Use

Use this skill when a project decision needs a tracked Markdown record because it constrains future work. Common scopes include:

  • process,
  • architecture,
  • backend choice,
  • role boundaries,
  • quality rules,
  • security posture,
  • release rules,
  • product direction,
  • accepted project conventions,
  • verification.

Strong ADR-style signals such as hard to reverse, surprising, or tradeoff-heavy still matter, but they are not the only trigger.

Verification operating decisions

This is a promotion path, not timeout handling. First use [[verification-evidence]] to record the task attempt. The maintainer then triages it and, when the observation affects repeated project work, records or updates the current VF-... fact in .agenticloop/project.md.

Use this skill for verification only when that already-recorded fact represents a policy-level conclusion that constrains future work, such as a project rule to use CI rather than local execution for a class of checks. The decision cites the VF-... fact and its durable task/event evidence, states the policy and revisit trigger, and follows the normal acceptance gate.

Do not use this skill for one timeout, ordinary timing noise, a retry choice, a task attempt, final timeout triage, or a mutable verification-fact update. Engineers report those observations; delegation observations never approve a strategy. A decision is not created merely because a check is expensive.

When Not to Use

Do not create a decision record for:

  • ordinary task notes,
  • implementation summaries,
  • raw meeting notes,
  • raw chat transcripts,
  • temporary debugging observations,
  • one-off local experiments that do not constrain later work,
  • a current, non-binding project operating fact – record it in ## Project Operating Facts in .agenticloop/project.md instead,
  • a compact pointer to a runbook – that is a Project Operating Fact, not a decision.

decision-capture is a skill published in the GitHub repository bartoszarendt/agenticloop (2 stars, last pushed 14d ago), licensed MIT. It adds 78 tokens to every session and 1,815 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.
