Forge-Agentic-Coding-CLI: Skill for Claude Code

.claude/skills/plan-synthesize/SKILL.md

plan-synthesize is a skill for Claude Code from hoangsonww/Forge-Agentic-Coding-CLI. It costs 40 tokens per session (424 once invoked), scanned A, original, MIT.

A process for combining two or more competing coding plans into one revised plan. It uses a chosen primary plan, applies useful changes from the others, and supports later refinement.

In plain words
What is it for?
Use it after a planning command has produced multiple plan files, especially when you want to compare proposals, integrate revisions, and refine the combined plan.
Why use it?
It helps resolve disagreements between plans without choosing ideas from only one of them. The result brings stronger parts of several proposals into a single document.

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

plan-synthesize 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 2mo 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

/plan-synthesize — best-of-all-worlds

Feed competing plans into a single GPT Pro session and produce a hybrid that integrates the strongest ideas from every input.

Workflow

  1. Pick a primary. Choose the best of the competing plans as your "base" — usually GPT Pro's. Its content gets the git-diff revisions applied to it.

  2. Open the synthesis prompt. Read .flywheel/prompts/plan-synthesize-best-of-all-worlds.md. Copy it into a fresh GPT Pro (web) conversation.

  3. Paste the base plan, then each competitor. Label each clearly.

  4. Receive git-diff revisions. GPT Pro will produce a list of diff-style changes integrating the best ideas.

  5. Apply in-place with Claude / Codex. Use the prompt in .flywheel/prompts/plan-integrate-synthesis.md. The agent applies the diffs to .flywheel/plans/<date>-<slug>-gpt-pro.md (renaming it to -hybrid.md is a good practice) and reports which revisions it wholeheartedly agrees with, somewhat agrees with, or disagrees with.

  6. Iterate. Use .flywheel/prompts/plan-refine.md in fresh GPT Pro conversations 4–5 more times until convergence.

  7. Sanity overshoot. Once per synthesis, run .flywheel/prompts/overshoot-mismatch-hunt.md to catch elements the model silently dropped.

Output

A single hybrid plan at .flywheel/plans/<date>-<slug>-hybrid.md. This is the one you'll feed into /plan-to-beads.

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.
