Cy Workflow Memory

Critical Rules

• Do not invent history, decisions, or status that did not happen.
• Do not copy large code blocks, stack traces, or task specs into memory files.
• Do not duplicate facts that are obvious from the repository, git diff, task file, or PRD documents.
• Do not read unrelated task memory files unless the shared workflow memory or the caller explicitly points to them.
• Keep shared memory durable and cross-task. Keep task memory local and operational.

Promotion Decision Test

Before promoting an item from task memory to shared workflow memory, ask:

1. Will another task need this information to avoid a mistake or rediscovery?
2. Is this fact durable across multiple runs, not just the current execution?
3. Is this information NOT already obvious from the PRD, techspec, task files, or the repository itself?

All three must be "yes" to promote. If any is "no," the item stays in task memory.

Examples that belong in shared workflow memory:

• A discovered constraint that affects multiple tasks (e.g., "the API rate limits to 100 req/s, batch operations must respect this")
• A cross-cutting architectural decision made during implementation (e.g., "chose channel-based coordination over mutex for the pipeline")
• An open risk that future tasks must account for (e.g., "migration depends on schema v3 which is not yet deployed to staging")

Examples that stay in task memory:

• Files touched during this task's implementation
• Debugging steps taken to resolve a task-specific error
• The current task's objective and acceptance criteria snapshot
• A workaround applied only to the current task's scope

Compaction Rules

When the caller flags a memory file for compaction, apply these rules inline. Read references/memory-guidelines.md for full detail, but these rules are sufficient for most compaction passes:

1. If both files need compaction, compact the shared workflow memory first, then compact the task memory. The shared file sets the cross-task context that the task file should not duplicate.
2. Preserve: current state, durable decisions, reusable learnings, open risks, and handoff notes.
3. Remove: repetition, stale notes, long command transcripts, and facts already derivable from the repository, PRD, or task files.
4. Rewrite retained items as short factual bullets. Do not preserve narrative logs or chronological play-by-play.
5. Keep the default section headings from the template intact. Remove empty sections only if they are truly unused.

When To Read the Reference

Read references/memory-guidelines.md when any of these apply:

• the caller requests compaction and the inline rules above do not cover the situation
• it is unclear what belongs in shared memory versus task memory
• the current memory file has drifted into noisy notes or redundant detail

Error Handling

• If any caller-provided memory path is missing, stop and report the mismatch instead of guessing another path.
• If memory content conflicts with the repository or task specification, trust the repository and task documents, then correct the memory file.
• If compaction would remove active risks, decisions, or handoff context, keep those items and remove lower-value repetition first.
