An agentic software-development methodology: composable skills that push a coding agent through spec, plan, TDD and review instead of straight into code.
Planning with Files
Summary
File-based planning for long-running agent tasks — crash-proof markdown plans that survive /clear and compaction, with per-turn re-injection and a deterministic completion gate.
Features
- Plans live in markdown files on disk, not in the context window
- Survives /clear, context compaction and crashed sessions
- Per-turn re-injection keeps plan state in front of the model against context rot
- Deterministic completion gate — done means every recorded step is closed
- Session recovery for tasks that run for hours
- Built on the open Agent Skills standard
- Works with Claude Code, Codex, Cursor, Kiro, OpenCode and 60+ agents
- No server or daemon — a plain skill directory

Skill Content
Description
Long agent runs fail in a characteristic way: the plan lives in the context window, the context gets compacted or cleared, and the agent quietly forgets half of what it set out to do. This skill moves the plan out of context and onto disk, in the style popularised by Manus.
The plan is a plain markdown file the agent writes and re-reads. Because it is a file rather than conversation history, it survives /clear, survives compaction, and survives a crashed session — the agent can pick the task back up by reading the file. Per-turn re-injection puts the current plan state back in front of the model on every turn, which is the direct countermeasure to context rot on tasks that run for hours.
A deterministic completion gate is the other half. Rather than letting the model decide it is finished, the skill checks the plan file for outstanding items, so "done" means every recorded step is actually closed. Session recovery, crash-proof writes and explicit state transitions are what make it usable for genuinely long-running work rather than a single sitting.
It is written against the open Agent Skills standard, so it runs in Claude Code, Codex, Cursor, Kiro, OpenCode and, by the project's count, more than 60 other agents. Installation is a plain skill directory drop — no server, no daemon, no runtime dependency beyond the agent itself.
