do

do is a skill for Claude Code from MSApps-Mobile/claude-plugins. It costs 92 tokens per session (575 once invoked), scanned A, original, MIT.

A task runner that recalls relevant saved project context before carrying out a request. It is intended for implementation tasks such as building, fixing, or continuing work.

In plain words
What is it for?
Use it when asking an agent to implement, fix, build, continue, or pick up work that may have been done before.
Why use it?
It reduces repeated investigation and helps avoid decisions or errors already recorded in project memory. It can also save important findings and decisions during the task.

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

do 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 1mo 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.

What it actually says

do: Memory-Aware Task Execution

Every task you run should start from what you know, not from zero.

Execution Workflow

Before you start: Load context

# What's already done / decided related to this task?
COWORK_MEM_DB=~/mnt/.claude/.cowork-mem/memory.db \
python3 {SKILL_DIR}/scripts/vector_search.py "<task description>" --limit 8

# Any relevant errors or blockers?
python3 {SKILL_DIR}/scripts/memory_store.py search "<key term>" --type error --limit 5

Use the recalled context to:

  • Skip work that's already done
  • Avoid approaches that previously failed (check errors)
  • Follow established patterns (check past decisions)
  • Build on existing file structure (check file_edits)

During execution: Save what matters

As you work, save observations for significant actions:

# When you make a choice
python3 {SKILL_DIR}/scripts/memory_store.py add decision \
  "<what you chose and why>" --tags "<task-tag>"

# When you discover something non-obvious
python3 {SKILL_DIR}/scripts/memory_store.py add insight \
  "<what you learned>" --tags "<task-tag>"

# When you hit an error and solve it
python3 {SKILL_DIR}/scripts/memory_store.py add error \
  "<error encountered + solution>" --tags "<task-tag>"

Don't over-log. Save things future-you would want to know that aren't obvious from the code.

After completion: Close the loop

python3 {SKILL_DIR}/scripts/memory_store.py add note \
  "Completed: <what was done>. Status: <done/partial>. Next: <what remains>" \
  --tags "completed,<task-tag>"

Parallelism with PostToolUse Hook

If the PostToolUse hook is active, file edits and bash commands are captured automatically. Focus your manual saves on:

  • Decisions (why you chose this approach)
  • Insights (non-obvious things you discovered)
  • Errors (problems and solutions)

The hook handles the "what happened"; you handle the "why it matters."

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.
