gsd:capture

A command for capturing ideas, tasks, notes, backlog items, and future ideas into the project's planning files. Different flags send the captured item to the matching planning workflow.

In plain words
What is it for?
Use it to create a todo, save a quick note, add an item to the backlog, record a future idea with trigger conditions, or browse pending todos.
Why use it?
It prevents useful thoughts from being mixed together or forgotten. It also gives each kind of captured information a predictable place and follow-up process.

Made for: Claude Code.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 644 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

gsd: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 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.

What it actually says

Mode routing:

  • default (no flag): Capture as a structured todo for later work → add-todo workflow
  • --note: Zero-friction idea capture (append/list/promote) → note workflow
  • --backlog: Add an idea to the backlog parking lot (999.x numbering) → add-backlog workflow
  • --seed: Capture a forward-looking idea with trigger conditions → plant-seed workflow
  • --list: List pending todos and select one to work on → check-todos workflow
Flag Destination Workflow
(none) Structured todo in .planning/todos/ add-todo
--note Timestamped note file, list, or promote note
--backlog ROADMAP.md backlog section (999.x) add-backlog
--seed .planning/seeds/SEED-NNN-slug.md plant-seed
--list Interactive todo browser + action router check-todos

Parse the first token of $ARGUMENTS:

  • If it is --note: strip the flag, pass remainder to note workflow
  • If it is --backlog: strip the flag, pass remainder to add-backlog workflow
  • If it is --seed: strip the flag, pass remainder to plant-seed workflow
  • If it is --list: pass remainder (optional area filter) to check-todos workflow
  • Otherwise: pass all of $ARGUMENTS to add-todo workflow

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.

gsd:capture is a command published in the GitHub repository mrboups/xbrain (2 stars, last pushed 17d ago), licensed MIT. It adds 17 tokens to every session and 644 once invoked, about $0.0001 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.
