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	Description
show [tag]	Print index or filter entries by tag
search <query>	Full-text search across all memory files
add <category> <title>	Append a new entry (prompts for details)
edit <entry-id>	Find entry by date+title slug and update in place
prune	Remove stale, superseded, and orphaned entries
archive	Move entries older than 30 days to cold storage
clear	Wipe all memory (with confirmation, recoverable)
stats	Counts, tier breakdown, tag frequency, oldest/newest
migrate	Import entries from legacy ~/.claude/hyperflow-memory.md
off	Disable memory writes for this session
compact	Summarise aged memory entries into stubs + monthly archive sidecars

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:** ...

Update index.md with the new row.

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• Remove [SUPERSEDED] entries older than 7 days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. Update index.md tier column.

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.

Error Handling

Failure	Behavior
.hyperflow/memory/ missing	Auto-create skeleton (index.md + 5 category files + archive/.gitkeep) on first write; for read-only subcommands, print (no memory yet — invoke /hyperflow:scaffold first).
Subcommand unknown	Print subcommands table; suggest closest match via Levenshtein distance.
add with invalid category	Reject and list valid categories: learning, decision, pitfall, pattern, convention.
edit entry id not found	List 3 closest matches by title slug + date.
clear without confirmation (headless)	Refuse and print clear requires interactive confirmation. Do not wipe.
migrate source file missing	Print (nothing to migrate — ~/.claude/hyperflow-memory.md not found) and stop.

Examples

3 entries (3 hot, 0 warm, 0 cold)

Search

/hyperflow:cache search "validator"

Add a learning

/hyperflow:cache add learning "Markdown frontmatter needs block scalar for colons"

? What: Block scalar (|) preserves : and backticks in YAML values
? Why it matters: prevents fatal YAML parse failures in marketplace validators
? Tags: yaml, validator, frontmatter
