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 | Find entry by date+title slug and update in place | | prune | Remove stale, superseded, and orphaned entries | | archive | Move entries older than 30 days to cold storage | | clear | Wipe all memory (with confirmation, recoverable) | | stats |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Remove [SUPERSEDED] entries older than 7 days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:

The compact subcommand handler reads the target memory file (default: learnings.md; pass a path to target another).
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.
The Compaction Writer is dispatched in a single batch with all eligible entries.
The Stub formatter renders each replacement line as ### [YYYY-MM-DD] Short title [domain, type] — summarized, see archive/YYYY-MM.md.
The Dedup Reviewer performs source-side stub-line match and archive-side header match (date + title + tags on both sides) to prevent duplicates.
The Archive-sidecar writer appends accepted entries to archive/YYYY-MM.md, grouped by each entry's calendar month.
The source file is rewritten with stubs replacing the original entries.
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

Parse invocation to determine subcommand
If subcommand missing → list subcommands table above with one-line descriptions
Execute subcommand
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:

Parse the subcommand from the user's invocation (or list subcommands if none given).
Validate prerequisites for the chosen subcommand (e.g. clear requires AskUserQuestion confirmation; migrate requires legacy file presence).
Execute the subcommand against .hyperflow/memory/.
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

Show all entries

/hyperflow:cache show

Date         Title                              Tags                  File              Tier
2026-05-16   Bash scoping required by validator [validator, marketplace] learnings.md   hot
2026-05-15   No AI attribution in commits       [convention, git]     conventions.md    hot
2026-05-14   Per-task commits in plugin dev     [convention, git]     conventions.md    hot
3 entries (3 hot, 0 warm, 0 cold)

Search

/hyperflow:cache search "validator"

.hyperflow/memory/learnings.md:42 — "Jeremy's validator requires scoped Bash..."
.hyperflow/memory/decisions.md:8 — "...validator score of 73 → 94 after fix"
2 matches

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
Added — .hyperflow/memory/learnings.md (entry 2026-05-16-block-scalar-frontmatter)
