make-plan

A planning workflow that uses notes from earlier sessions to create a grounded work plan. It considers recent work, decisions, blockers, errors, and possible next steps.

In plain words
What is it for?
Use it to plan upcoming work, organise a sprint, prioritise tasks, decide what to do next, and identify blockers or unanswered questions.
Why use it?
It avoids planning from scratch when important project context is already recorded elsewhere.

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

make-plan 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 2d 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

make-plan: Memory-Grounded Planning

A good plan starts from the current state, not a blank slate. Memory tells you what's been decided, what's blocking progress, and what was left mid-session.

Planning Workflow

1. Load context from memory

# What was done recently?
python3 {SKILL_DIR}/scripts/memory_store.py timeline --hours 168 --limit 30

# What's in progress / blocked?
COWORK_MEM_DB=~/mnt/.claude/.cowork-mem/memory.db \
python3 {SKILL_DIR}/scripts/vector_search.py "in progress blocked next step" --limit 10

# What did the last session summary say?
python3 {SKILL_DIR}/scripts/memory_store.py search "session summary" --type summary --limit 5

2. Check for known errors or constraints

python3 {SKILL_DIR}/scripts/memory_store.py search "error bug blocked" --type error --limit 5

3. Build the plan

Structure the plan as:

  • Context: What we know from memory (1-3 bullets, specific)
  • Goal: What we're trying to accomplish
  • Steps: Numbered, specific, actionable — reference actual files and systems
  • Blockers: Known issues from memory that affect the plan
  • Open questions: Things we'd need to investigate

4. Save the plan as a decision

python3 {SKILL_DIR}/scripts/memory_store.py add decision \
  "Plan: <summary of steps>" --tags "plan,session-goal"

Planning Tips

  • Plans built from memory are more accurate than plans from scratch — use it
  • Surface blockers from memory explicitly; don't let them be surprises mid-sprint
  • If memory has conflicting decisions, flag it for the user to resolve
  • Short plans (3-5 steps) are better than exhaustive ones — you can always plan the next thing after
Changes

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.

make-plan is a skill published in the GitHub repository MSApps-Mobile/claude-plugins (9 stars, last pushed 6d ago), licensed MIT. It adds 86 tokens to every session and 527 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.
