Cache

Cache

CRUD interface for .hyperflow/memory/. Full protocol: memory-system.md.

Storage

All operations target .hyperflow/memory/ at the project root. Never modify source code files — if asked to "remember X about file Y", add a memory entry only, never edit Y.

Subcommands

Subcommand Details

show [tag]

No arg → print index.md. With tag → filter all files for matching entries. Output table: Date | Title | Tags | File | Tier

search <query>

grep/ripgrep across learnings.md, decisions.md, pitfalls.md, patterns.md, conventions.md. Return file:line + snippet, ranked by relevance.

add <category> <title>

Categories: learning decision pitfall pattern convention Prompt via AskUserQuestion for: what, why it matters, tags (controlled vocab). Append to the matching file using:

### [YYYY-MM-DD] <title>  `[tag1, tag2]`
**What:** ...
**Why it matters:** ...
**Evidence:** ...

That is the whole write. index.md is derived — scripts/memory-index.py rebuilds it at the next session start. Never append index rows by hand; to refresh it now, run python3 scripts/memory-index.py .hyperflow.

edit <entry-id>

Locate by date+title slug. Show current value, prompt for new value, update in place.

prune

Per memory-system.md pruning protocol:

• Remove [SUPERSEDED] entries older than 7 days
• Remove entries whose referenced files no longer exist (test -f)
• Archive entries unreferenced 90+ days to .hyperflow/memory/archive/YYYY-MM.md Print summary of removed/archived counts.

archive

Compress hot entries older than 30 days → .hyperflow/memory/archive/YYYY-MM.md. Leave one-line summary in original file. The stub keeps its date, so the derived index re-tiers it to cold on its own.

clear

Confirm via AskUserQuestion: "This wipes all memory for this project. Are you sure?" If yes → move all content to .hyperflow/memory/archive/cleared-<timestamp>.md, then reset files to empty stubs.

stats

Print: total entries, hot/warm/cold counts, tag frequency table, oldest and newest entry dates.

migrate

Read ~/.claude/hyperflow-memory.md, filter entries matching current project path. Append matching entries to learnings.md. Leave legacy file untouched. Print count of migrated entries.

off

Print: "Memory writes disabled for this session." No files modified.

compact

User-invoked memory compaction. Summarises entries older than 7 days into stub lines and preserves the full text in monthly archive sidecars at .hyperflow/memory/archive/YYYY-MM.md.

Flow:

1. The compact subcommand handler reads the target memory file (default: learnings.md; pass a path to target another).
2. The Date/tag parser splits entries into hot (≤7 days, preserved) and eligible (>7 days). Both [domain, type] and legacy backticked `[domain, type]` tag forms are accepted.
3. The Compaction Writer is dispatched in a single batch with all eligible entries.
4. The Stub formatter renders each replacement line as ### [YYYY-MM-DD] Short title [domain, type] — summarized, see archive/YYYY-MM.md.
5. The Dedup Reviewer performs source-side stub-line match and archive-side header match (date + title + tags on both sides) to prevent duplicates.
6. The Archive-sidecar writer appends accepted entries to archive/YYYY-MM.md, grouped by each entry's calendar month.
7. The source file is rewritten with stubs replacing the original entries.
8. The compact subcommand handler refreshes .hyperflow/memory/.checksums (a memory-scoped sidecar — distinct from .hyperflow/.checksums which the scaffold staleness check owns) and exits with a summary.

Output: N entries compacted into archive/YYYY-MM.md · M stubs rejected as duplicates · source N→M lines. Full protocol in compaction.md.

Flow

1. Parse invocation to determine subcommand
2. If subcommand missing → list subcommands table above with one-line descriptions
3. Execute subcommand
4. Print structured result with counts/changes summary

Overview

/hyperflow:cache is the operator interface to project-scoped memory under .hyperflow/memory/. It's the only skill that mutates memory files directly (other skills append via the memory-system protocol). Subcommands cover the full lifecycle: show, search, add, edit, prune, archive, clear, stats, migrate. All operations are project-local — entries never leak across projects.

Prerequisites

• .hyperflow/ initialized (run /hyperflow:scaffold if missing — cache creates .hyperflow/memory/ on first write but expects the parent dir).
• Write access to .hyperflow/memory/ and .hyperflow/memory/archive/.
• For migrate only: read access to ~/.claude/hyperflow-memory.md (legacy global memory).

Instructions

See Subcommands and Subcommand Details above for the full operational spec. Summary:

1. Parse the subcommand from the user's invocation (or list subcommands if none given).
2. Validate prerequisites for the chosen subcommand (e.g. clear requires AskUserQuestion confirmation; migrate requires legacy file presence).
3. Execute the subcommand against .hyperflow/memory/.
4. Print structured result with counts and any file-level changes.

Output

Each subcommand prints a compact summary:

• show — table of matching entries (Date | Title | Tags | File | Tier).
• search — file:line matches with snippets, ranked by relevance.
• add / edit — confirmation line with new entry id and target file.
• prune / archive / clear — counts of removed/archived/cleared entries plus destination paths.
• stats — totals + hot/warm/cold breakdown + top-N tags.
• migrate — count of migrated entries + source legacy file path.
• off — single-line Memory writes disabled for this session.
