Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.6.1] - 2026-05-08

Added

• Native OpenCode TUI /memory-status, /memory-list, and /memory-help display commands for local memory statistics, current workspace memory refs, and help.
• Package ./tui export for OpenCode TUI plugin loading.

Changed

• README documents separate server and TUI plugin configuration.
• Recent activity/last TUI commands were removed before release because duplicate-looking slash menu entries were not useful.

Fixed

• Replaced a literal NUL byte in workspace-memory.ts regex source with a \0 escape so source search tools treat the file as text.

Notes / Known UX

• TUI memory command output is injected as no-reply user-style conversation text and does not call the LLM.

[1.6.0] - 2026-05-08

Added

• Numbered compaction memory references ([M1], [M2], ...) for existing rendered workspace memories.
• Compaction memory commands: REINFORCE [M#] for retention reinforcement and REPLACE [M#] [type] text for protected replacement.
• CompactionMemoryRef session-state snapshots with optional compaction IDs for overlap detection.
• Evidence events for numbered memory command outcomes: memory_reinforced, memory_replaced_numbered_ref, and memory_reverted_numbered_ref.
• Public memory-diag commands report for command counts, outcomes, rejection reasons, protected replacement blocks, malformed commands, and latest command events.
• Public dry-run-first memory-diag revert command for manually reverting successful numbered replacements by replacement memory ID or evidence event ID.
• Hard quality rejection reasons for unresolved questions, transient bug/debug state, and deployment snapshots.
• Soft terse_label diagnostic for very short label-like candidates.
• Regression tests for command parsing, REINFORCE, protected REPLACE, revert behavior, compaction ref validation, overlap protection, and fallback behavior when the model omits the compaction snapshot ID.

Changed

• Compaction prompts now include numbered memory refs and concise memory-operation rules instead of asking the model to reuse existing wording exactly.
• Compaction no longer duplicates hot session state inside the compaction prompt; hot state remains available in normal prompt context.
• Duplicate maintenance now prefers explicit REINFORCE or protected REPLACE evidence over silent duplicate restatement.
• Rendered decision memory cap increased from 10 to 12 while keeping the global rendered cap at 28.
• Rejected memory command evidence now uses neutral target relations instead of lifecycle-mutating reinforced or superseded relation roles.
• memory-diag public command metadata now includes commands and revert alongside status, rejected, missing, and explain.

Fixed

• Overlapping same-session compactions can no longer silently apply numbered commands against the wrong snapshot when the snapshot ID is present.
• Numbered command resolution now rejects stale refs whose memory ID, status, or exact key no longer match the current workspace memory entry.
• Protected replacements are surfaced as first-class diagnostics instead of being buried in generic rejection counts.

Recovery note

Successful numbered replacements supersede the original memory and add a replacement. To inspect or recover one, run memory-diag commands --verbose, then dry-run memory-diag revert --memory <replacement-memory-id> or memory-diag revert --event <event-id> before adding --apply.

[1.5.5] - 2026-05-05

Added

• Section-aware greedy line accumulator for hot session state rendering that fits whole lines instead of truncating mid-line.
• accountHotSessionStateRender() accounting function returning prompt text, omitted items, and char budget for v2 evidence extension.
• Exported types for render accounting diagnostics: HotStateSection, HotStateOmissionReason, HotStateOmittedItem, HotSessionStateRenderAccounting.
• 9 direct unit tests for hot session state rendering covering empty state, ranking, section caps, char budget, boundary conditions, header suppression, wrapper parity, and newline counting.
• Two-layer omission model: section caps first (section_cap), then char budget (char_budget), with clear per-item omission reasons.

Changed

• Hot session state rendering no longer uses blunt .slice(0, maxRenderedChars) prompt truncation.
• Header-only sections are suppressed: a section is only rendered if at least one entry line fits the char budget.
• renderHotSessionState() is now a delegation wrapper to accountHotSessionStateRender().prompt, preserving backward compatibility.
• Fixed docs/configuration.md active-file ranking formula: was count * action_weight * recency_decay with weights 4/3/2/1, now correctly ACTION_WEIGHT[action] + count * 3 with weights edit 50, write 45, grep 30, read 20, tie-break by lastSeen descending.
• Clarified README.md system prompt injection order: workspace memory and hot state index positions depend on whether workspace memory state is available.

Fixed

• Hot session state prompt could be truncated mid-line under the old .slice() budget enforcement.

[1.5.4] - 2026-05-02

Changed

• Centralized the supported memory-diag command metadata for the official public commands: status, rejected, missing, and explain.
• Removed pre-public legacy aliases so unsupported spellings now use the standard unknown-subcommand path instead of carrying v2.0 compatibility debt.
• Kept coverage and audit as hidden maintainer diagnostics with neutral maintainer-only notices.
• Removed public npm script exposure for the internal workspace cleanup tool while keeping the development tool in the repository.

Fixed

• Moved missing-memory disappearance detail formatting into the official missing formatter before deleting legacy disappearance formatter code.

[1.5.3] - 2026-05-02

Added

• Published the read-only memory-diag package binary for package-qualified npx --package opencode-working-memory memory-diag usage.
• Added user-facing diagnostics commands for concise status, rejected memory review, missing memory review, and per-memory explanation.

Changed

• Reworked the diagnostics CLI into focused command, model, formatter, and utility modules while preserving legacy aliases and maintainer diagnostics.
• Updated README and configuration docs to document the supported memory-diag CLI workflow and package-qualified npx usage.
• Raised the Node.js requirement to >=22.6.0 for the TypeScript diagnostics CLI runtime.

Fixed

• Avoided repeated workspace snapshot construction in status diagnostics.
• Replaced per-memory evidence summary lookups with grouped evidence processing to avoid N+1 diagnostics work.
• Added top-level CLI error handling for cleaner user-facing failures.
• Removed a diagnostics model circular dependency by extracting evidence grouping helpers to a neutral module.

[1.5.1] - 2026-04-30

Added

• Per-workspace evidence log for extraction, promotion, reinforcement, render, storage, and hook lifecycle events.
• memory-diag health --json for machine-readable diagnostics.
• memory-diag explain for per-memory render status, strength, reasons, and evidence event IDs.
• memory-diag trace --memory <id> for memory lifecycle history.
• UTC calendar-day reinforcement gate so repeated matches cannot inflate a memory multiple times in the same day.

Changed

• Retention constants and calculations moved to src/retention.ts.
• safetyCritical is now fully inert: no retention multiplier and no type-cap bypass, while remaining JSON-compatible.

[1.5.0] - 2026-04-29

Added

• Strength-based workspace memory retention using exponential decay instead of additive priority scoring.
• Per-type rendered caps for workspace memory candidates: feedback 10, decision 10, project 8, and reference 6.
• Dormant-workspace effective age: after 14 days without activity, additional dormant time counts at 0.25x for retention decay.
• Reinforcement tracking for repeated memories, with same-session and one-hour guards to prevent accidental reinforcement spam.
• Memory health diagnostics for stored vs rendered counts, type caps, global cap overflow, dormancy, retention monitoring, and strength-ranked top/weakest entries.
• CLI smoke tests and regression fixtures covering retention decay, stale-prune removal, type caps, reinforcement, invalid timestamps, and diagnostics.

Changed

• Workspace memory rendering now ranks entries by retention strength, not the previous priority/penalty model.
• Confidence is retained for compatibility but no longer affects retention scoring.
• Deprecated safetyCritical is retained for JSON compatibility but no longer affects retention strength or type-cap behavior.
• Old or stale-marked memories are no longer hard-pruned; they remain stored and only fall out of rendered context through strength and cap competition.
• Existing duplicate promotion and dedupe paths now reinforce the surviving memory instead of only absorbing the duplicate.
• Health output now separates stored active memories from rendered candidates to make cap behavior easier to understand.
• Default prompt budgets are lower after calibration against observed rendered output: workspace memory is 3600 characters and hot session state is 700 characters.

Fixed

• Invalid updatedAt or retentionClock values no longer produce NaN retention strength or unstable sorting.
• Dormant age calculation only discounts the dormant overlap since an entry was created, so new memories do not inherit old workspace dormancy.
• Type max totals above the global cap are handled correctly: the global rendered limit still wins.

Not Included Yet

• Delete tombstones and explicit supersedes chain enforcement remain deferred follow-up work.
• Hot/warm/cold tiered storage remains a future v1.6 direction.

[1.4.0] - 2026-04-28

Added

• Local migration audit log for the 2026-04-28-quality-cleanup migration: ~/.local/share/opencode-working-memory/migration-logs/2026-04-28-quality-cleanup.jsonl.
• Local extraction rejection log for rejected compaction memory candidates: ~/.local/share/opencode-working-memory/extraction-rejections.jsonl.
• Sanitized real-workspace regression fixtures for memory cleanup migration behavior.
• Safe workspace residue cleanup tooling that dry-runs by default and quarantines definite temp/test workspace stores instead of deleting them.

Changed

• Unified memory quality rules in a shared quality gate for compaction memory candidates and cleanup checks.
• Rewritten compaction memory prompt to reduce over-production of low-quality memories.
• Changed quality cleanup migration to be conservative: it supersedes only high-confidence garbage patterns, including progress snapshots, raw errors, commit/CI snapshots, temporary status notes, active file snapshots, code/API signatures, path-heavy entries, and empty entries.
• Soft heuristic failures (bad_feedback, bad_decision) are intentionally excluded from automatic migration cleanup to protect durable declarative memories such as branding rules, API facts, release rules, user workflow preferences, and architecture decisions.
• Isolated test runs under a temporary XDG_DATA_HOME so test workspaces no longer pollute real local workspace memory data.

Recovery note

The cleanup migration changes matching entries to status: "superseded"; it does not delete the entry. If a useful memory is superseded, inspect the migration audit log and restore by changing that entry back to status: "active" in the workspace's workspace-memory.json. The migration runs once per workspace.

[1.3.3] - 2026-04-28

Fixed

• Added atomic cross-process storage writes with stale-lock recovery and heartbeat refresh to prevent concurrent memory-file corruption.
• Scoped pending-memory promotion by owner/session so global unowned cleanup no longer removes active owned entries.
• Retained source-aware pending memories until they are actually promoted, absorbed, superseded, or rejected.
• Persisted load-time security redaction and expanded Bearer-token redaction to reduce secret retention risk.
• Hardened workspace normalization, cache bounds, rejected-entry retention, and session cleanup behavior.

[1.3.2] - 2026-04-27

Fixed

• Compatibility CI now installs dependencies with npm install so it works in this no-lockfile repository.
• Compatibility CI now runs on Node 24, matching the test command's --experimental-strip-types requirement.

[1.3.1] - 2026-04-27

Added

• Pending journal retention: max 50 entries, 30-day TTL, automatic pruning on save.
• Plugin capability test to catch missing OpenCode hooks before release.
• CI workflow for weekly OpenCode plugin API compatibility testing.
• Indirect prompt-injection filtering for workspace memory candidates.
• Expanded credential redaction for common API key, token, secret, credential, auth, and private-key labels.

Fixed

• Pending memory journal entries are now bounded and pruned instead of growing indefinitely.
• Adversarial memory candidates that try to override system instructions are rejected before storage.
• Broader credential-like labels are redacted from workspace memory text.

Changed

• Memory dedupe is now repo-agnostic: project/reference entries use exact canonical text plus generic URL/path identity, while decision/feedback entries no longer use repository-specific topic heuristics.
• OpenCode plugin compatibility is documented and declared as >=1.2.0 <2.0.0.
• README limitations now concisely document compatibility, secret handling, semantic-memory scope, plugin ordering, and multi-process write boundaries.

Known Limitations

• Compatibility is tested against OpenCode plugin API >=1.2.0 <2.0.0.
• Credential redaction is best-effort; do not store secrets.
• This is working memory, not semantic search.
• Other prompt or compaction plugins may conflict depending on plugin order.
• Multi-process writes to the same workspace are not fully serialized.

[1.3.0] - 2026-04-27

Added

• P0 consolidation accounting for workspace memory promotion.
• Accounting-aware deduplication (dedupeLongTermEntriesWithAccounting).
• Accounting-aware normalization (normalizeWorkspaceMemoryWithAccounting).
• Promotion classification: promoted, absorbed, superseded, rejected.
• Remove absorbed/superseded keys from rejected set to avoid duplicate rejection tracking.
• Memory quality evaluation fixtures covering accepted durable facts and rejected noisy facts.
• Sharper compaction memory extraction prompt with concrete good/bad memory examples.

Fixed

• Promotion accounting now clears only pending memories that survive workspace normalization/cap limits.
• session.deleted now uses shared session ID extraction, matching session.compacted behavior.
• Absorbed duplicate pending memories are accounted for instead of retrying forever.
• Active vs superseded boundary when promoting pending memories (superseded entries no longer block promotion of same-key active memories).
• Removed unused rejected_duplicate_lower_quality type.

Changed

• Deferred pending journal safety cap implementation (see TODO in src/pending-journal.ts).
• Clarified superseded accounting semantics: P0 emits events only, does not archive newly superseded records.
• README structure was streamlined around the automatic memory flow and ongoing memory-quality work.
• Architecture docs now describe Memory candidates: as the primary extraction format and XML candidate blocks as legacy.
• Superpowers implementation plans are no longer tracked in git.

[1.2.3] - 2026-04-26

Added

• Frozen workspace memory snapshot in system[1] for better OpenCode prompt-cache stability.
• Ephemeral hot session state and pending memories in later system messages.
• Durable pending journal so explicit memories survive until promotion.

Fixed

• Explicit memories no longer mutate the frozen workspace snapshot mid-session.
• Pending memories are promoted at safe cache-epoch boundaries.

[1.2.0] - 2026-04-25

Added

• Memory V2 three-layer architecture.
• Workspace memory for durable cross-session decisions, preferences, project facts, and references.
• Hot session state for active files, open errors, and recent context.
• Hook-based memory extraction during OpenCode compaction.

Changed

• Removed manual memory tools in favor of automatic prompt injection.
• Moved storage to ~/.local/share/opencode-working-memory/.

[1.1.0] - 2026-04-24

Changed

• Improved pre-V2 memory documentation and installation flow.

[1.0.0] - 2026-04-23

Added

• Initial release with three-layer memory architecture.
• Initial OpenCode memory integration.
• Basic memory extraction and prompt injection.
