gtd-capture

gtd-capture is a skill for Claude Code from MadAppGang/magus. It costs 37 tokens per session (938 once invoked), scanned A, original, MIT.

A task-capture helper for the Getting Things Done (GTD) method, which collects commitments and ideas into an inbox. It also recognises items you are waiting for or want to postpone.

In plain words
What is it for?
Use it to spot phrases such as “remind me” or “we should” and route them to an inbox, waiting list, or someday list.
Why use it?
It reduces the chance that tasks mentioned in conversation or code comments are forgotten. It also limits repeated capture suggestions during one session.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

gtd-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 8d 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.

GTD Capture Skill — Proactive Capture Trigger Detection

When This Skill Applies

Apply this skill whenever you detect any of the following semantic signals in the user's messages or code:

Explicit Capture Signals (→ Inbox)

  • "I need to ___", "we need to ___", "you need to ___"
  • "we should ___", "I should ___", "we ought to ___"
  • "remind me to ___", "don't forget ___", "remember to ___"
  • "TODO:", "FIXME:", "HACK:", "NOTE: action required"
  • "must ___", "have to ___", "got to ___"

Waiting For Signals (→ Waiting list)

  • "waiting on ___", "waiting for ___", "blocked by ___"
  • "once ___ is done", "after ___ finishes", "depends on ___"
  • "need ___ to respond", "need ___ from ___"

Deferral Signals (→ Someday/Maybe)

  • "someday", "eventually", "later", "at some point"
  • "when we have time", "would be nice to", "might want to"
  • "tech debt", "backlog item", "refactor (not now)"
  • "future improvement", "nice to have"

Frequency Guard

Maximum 2 capture suggestions per session. After 2 suggestions, stop offering — do not suggest a third time.

Track mentally whether you have already offered capture in this session.

How to Suggest

When you detect a capture signal, offer ONE of these phrasings (pick based on signal type):

Inbox capture:

Capture to GTD inbox? → "[detected text]" [y/N]

Waiting For capture:

Add to Waiting For: "[detected text]"? [y/N]

Someday/Maybe capture:

Add to Someday/Maybe: "[detected text]"? [y/N]

Response to User's Answer

If user says "y" or "yes": Run the Bash command to append to tasks.json:

CWD=$(pwd)
GTD_LIB="${CLAUDE_PLUGIN_ROOT}/hooks/gtd-lib.sh"
source "$GTD_LIB"
gtd_init
ID=$(gtd_new_id)
NOW=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
TASK_JSON=$(jq -n --arg id "$ID" --arg subject "<detected text>" --arg list "<inbox|waiting|someday>" --arg created "$NOW" \
  '{id: $id, subject: $subject, list: $list, context: [], parentId: null, energy: null, timeEstimate: null, waitingOn: null, dueDate: null, created: $created, modified: $created, completed: null, notes: ""}')
echo "$TASK_JSON" | gtd_append_task
bun run "${CLAUDE_PLUGIN_ROOT}/tools/gtd-display.ts" capture "$ID" "<detected text>" --list "<inbox|waiting|someday>"

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.

It adds 37 tokens to every session and 938 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
