debrief

debrief is a skill for Claude Code, Codex from danweinerdev/claude-sdd-planner. It costs 29 tokens per session (1,385 once invoked), scanned A, a copy of sdd-debrief, MIT.

A workflow for writing after-action notes when a phase of a project plan is complete. It records what happened compared with what was planned.

In plain words
What is it for?
Use it to review a completed plan phase and capture reusable notes for future work.
Why use it?
It preserves decisions, deviations, lessons, and effects so later phases can use them.

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

debrief 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 yesterday.

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.

Path Resolution

The plugin directory contains commands/, agents/, and shared/ as siblings. Find it by globbing for **/commands/research/SKILL.md in both the current directory and ~/.claude/plugins/cache/; if multiple versions match, sort them as semantic versions (like sort -V) and use the highest, then strip commands/research/SKILL.md from the match. Resolve the planning root (artifacts) and target repository per shared/path-resolution.md in the plugin directory.

When to Use

When a plan phase has been completed (or substantially completed) and you want to capture what happened: decisions made, deviations from plan, lessons learned, and impact on future phases.

Process

  1. Identify Target

    • Scan Plans/ for plans whose README frontmatter status is active and that have in-progress or completed phases (debriefs happen during active work)
    • Ask which plan and phase to debrief (or infer from context)
    • Read the phase document to understand what was planned
    • Read the plan README for overall context
  2. Gather Information

    • Review the phase's tasks and subtasks for completion status
    • Read every task's ### Completion Evidence — an absent or pending section on a complete task is a legacy evidence gap (shared/completion-evidence.md); report it in the debrief, never treat it as proof
    • Read related designs from Designs/ to identify deviations from intended architecture
    • Read related specs from Specs/ to assess requirements coverage
    • If more than ~3 related documents are involved, delegate the sweep to sdd-planner:researcher instead of reading them all yourself
    • Ask the user about:
      • Key decisions made during implementation
      • What deviated from the original plan or design
      • Problems encountered and how they were resolved
      • Insights to carry forward
  3. Spot Skill Opportunities Review the phase for repeated actions that would benefit from being enshrined as a reusable skill. Look for:

    • Manual sequences you (or the user) ran more than once — multi-step git workflows, recurring investigations, file-munging pipelines, check-lists that were applied by hand
    • Repeated workflow sequences that always went together
    • Codebase operations that lacked a helper/script and had to be redone in each task
    • Checks or validations that should have been automated but were done mentally
