Persistent episodic memory for AI coding: capture, retrieve, brief, dream cycle, cross-project.

Episodic memory system for coding tasks with capture, retrieval, and cross-project recall.

Tempera - Persistent Memory for Claude Code

Tempera gives Claude Code a persistent memory that learns from experience. Instead of starting fresh each session, Claude can recall past solutions, learn what works, and get smarter over time.

Why Tempera?

The Problem: Claude Code forgets everything between sessions. You solve the same problems repeatedly, and Claude can't learn from past successes or failures.

The Solution: Tempera captures coding sessions as "episodes", indexes them for semantic search, and uses reinforcement learning to surface the most valuable memories when relevant.

What Makes It "Learn"

Mechanism	What It Does
Feedback	Helpful episodes gain utility score
Multi-hop Bellman Propagation	Value spreads through the similarity graph across multiple hops
Session Chaining	Related episodes in multi-step tasks are linked and boost each other
Temporal Credit	Episodes before successes get credit (even across session boundaries)
Recency Boost	Fresh episodes can be weighted higher in retrieval (opt-in)
Scope-aware Decay	Project-bound claims fade in ~70 days; language-level facts last ~3 years; universal truths never decay
Verification State	Captures advance from `Untested` → `TestsPass` → `Merged` → `StableNoRevert`; later states weigh more
Calibration	Per-(task, project) verified vs. declared ratio surfaces overconfidence
Dream Cycle	Nightly reflection, pattern detection, contradiction probing, and template extraction
Self-Improvement Log	Tracks corrections, missed questions, and queues clarifying questions for next session
Cross-Project Transfer	Claims marked language / crate / domain / forever-scoped surface across projects

Over time, frequently helpful knowledge rises to the top, while stale or unhelpful memories fade away — and the system itself accumulates a per-project picture of where it tends to be wrong.

The bigger surfaces (v0.6 onward)

Beyond the basic capture/retrieve loop, Tempera ships several higher-order surfaces. Each is opt-in but all flow through the same MCP tools — Claude can use them without any custom client code.

Grounded capture (v0.6): Every captured claim carries a falsifiability score, a category, and a ValidityScope (Forever / Language / Crate / Domain / Workaround / Project). Decay rates are per-scope — universal truths never expire, project-specific conventions fade in months, workarounds expire when the underlying issue closes.
Dream cycle (v0.7): A budgeted nightly pipeline that runs verify_advance → decay → reflect → patterns → contradict → templates. Reflections turn high-signal days into prose; patterns surface themes that keep recurring; contradict probes pairs of frequently-retrieved episodes for factual disagreements; templates extract reusable step sequences from successful task clusters.
Self-improvement (v0.8): Calibration tracks the ratio of declared vs. verified successes per (task, project). Mistakes log records corrections the agent made. Should-have-asked log records questions it realized it should have asked first. Ask-backs are clarifying questions the system itself drafts via Haiku when a capture ends in failure with vague intent — queued for the next session in that project.
Brief surface (v0.9): One MCP call joins all of the above against the file set the agent is about to touch. tempera_brief(files, task_type?, domain?) returns pending ask-backs, the matching reasoning template, top correction categories for those files, should-have-asked triggers, and a calibration warning if the agent's track record on this kind of task is shaky.
Cross-project learning (v0.10): tempera_retrieve and tempera_brief both accept cross_project=true. Transferable claims (anything not project-scoped) surface across projects; Project-scoped knowledge stays bound to its codebase. Legacy captures default to non-transferable until reclassified.

Installation

Build from Source

bash

# Clone and build
git clone https://github.com/anvanster/tempera.git
cd tempera
cargo build --release

# Two binaries are created:
# - target/release/tempera      (CLI tool)
# - target/release/tempera-mcp  (MCP server for Claude Code)

Install from crates.io

bash

cargo install tempera

First Run - Model Download

On first use, Tempera downloads the BGE-Small embedding model (~128MB) for semantic search. This happens automatically and only once:

bash

# Initialize and trigger model download
tempera init

# Output:
# 🔄 Loading embedding model (this may download the model on first run)...
# ✅ Embedding model loaded

The model is cached globally at ~/.tempera/models/ and shared across all projects.

Setup with Claude Code

1. Add the MCP Server

bash

claude mcp add tempera --scope user -- /path/to/Tempera/target/release/tempera-mcp

The --scope user flag makes it available across all your projects.

2. Restart Claude Code

Exit and restart Claude Code to load the new MCP server.

3. Verify

Run /mcp in Claude Code. You should see tempera with 12 tools.

MCP Tools

Once connected, Claude has access to these 12 tools, grouped by purpose:

Session warmup (call at task start)

Tool	When to Use
`tempera_session_start`	Call ONCE at the very start. Returns any clarifying question tempera drafted after a previous failed/partial session in this project.
`tempera_brief`	Call once the file set is known. Joins pending ask-back, reasoning template, top correction categories for these files, should-have-asked triggers, and calibration warning into one response. Pass `task_type` + `domain` for richer output. Set `cross_project=true` to supplement with rows from other projects.
`tempera_retrieve`	Search for similar past episodes. Set `scope="cross-project"` to include transferable claims from other projects.
`tempera_template`	Pull the reasoning template stored for a `(task_type, domain)` pair. The step sequence past wins followed.

During task

Tool	When to Use
`tempera_log_correction`	When the user corrects an assumption / decision / piece of code. Categorized log; the brief surface uses it.
`tempera_log_should_have_asked`	When you realize mid-task you should have asked a question up front. Records the trigger context, the question, and the eventual answer.

End of task

Tool	When to Use
`tempera_capture`	Save session as an episode. Auto-detects session links and runs propagation. The intent-extraction LLM call also suggests a `ValidityScope` for cross-project routing.
`tempera_feedback`	Mark retrieved episodes as helpful or not. Drives the utility-learning loop.

Diagnostics + maintenance

Tool	When to Use
`tempera_status`	Per-project memory health snapshot.
`tempera_stats`	Statistics + trend analytics (helpfulness over time, domain growth, learning curve).
`tempera_propagate`	Multi-hop Bellman propagation with convergence tracking. Periodic maintenance.
`tempera_review`	Consolidate similar BKMs, cleanup. Run after related task series.

Standard warmup pattern

code

tempera_session_start          # is anything queued from last session?
tempera_brief(files, ...)      # what does tempera know about this exact change?
tempera_retrieve(query)        # then deep-dive into specific episodes

Key Lifecycle Behaviors

Start of session: Call tempera_session_start first to consume any pending ask-back, then tempera_brief once the file set is known.

End of task: Capture successful sessions with tempera_capture — don't wait to be asked. Capture also drafts an ask-back via Haiku if the outcome was Failure/Partial with vague intent, so the next session in this project sees the gap.

Session chaining: Episodes captured within 2 hours of each other in the same project are automatically linked. Multi-step tasks share utility and context.

Cross-project routing: New captures get a ValidityScope suggestion from the intent-extraction LLM (v0.10.3). Project-scoped claims stay bound to one codebase; Language / Crate / Domain / Workaround / Forever claims surface across projects when retrieval opts in.

tempera_retrieve Modes

code

Search:           tempera_retrieve(query: "authentication bug")
List all:         tempera_retrieve(all: true)
Show details:     tempera_retrieve(query: "abc12345")        # episode ID
Cross-project:    tempera_retrieve(query: "sqlx ordering", scope: "cross-project")

Example Conversation

code

User: Fix the login redirect vulnerability

Claude: [Calls tempera_session_start()]
        No pending ask-back — proceeding.

        [Calls tempera_brief(files: ["src/auth.rs", "src/router.rs"],
                             task_type: "bugfix", domain: "auth-middleware")]

        🔴 PENDING ASK-BACK
          Ask the user first: "Should auth run before or after request logging?"

        📋 REASONING TEMPLATE (bugfix / auth-middleware)
          url-redirect validation
            1. Find every redirect target read from request input
            2. Validate against allow-list or treat as untrusted
            3. Add regression test with adversarial input

        ⚠️  TOP CORRECTION CATEGORIES for these files
          - validation_skipped (3×)
          - host_header_trust (2×)

        Tempera says I've been wrong here before in specific ways.
        Let me ask: should auth run before or after logging?

User: Before — we need an auth'd subject for log lines.

Claude: [Implements with URL allow-list, following the template steps]

        Done. [Calls tempera_capture(
          summary: "Fixed login redirect by validating return URL against allow-list",
          outcome: "success",
          validity_scope: "domain:auth-middleware"
        )]
        ✅ Episode saved. (Cross-project — this is an auth-middleware pattern.)

User: That memory was helpful!

Claude: [Calls tempera_feedback(helpful: true, episodes: ["..."])]
        Marked helpful — future retrievals for similar tasks will rank this higher.

Data Storage

Tempera stores everything locally in ~/.tempera/ (shared across all projects). One memory pool serves every project; the project filter is applied at query time.

SQLite tables (in `jobs.sqlite`)

Everything that needs SQL lives here. Each store opens the DB on first use and runs its migration; migrations are in migrations/ and run in order.

Migration	Table	Purpose
0001	`jobs`	Background job queue with lease semantics
0002	`error_fingerprints`	blake3-hashed normalized error text
0003	`dream_verdicts`	Day-level Haiku triage cache
0004	`reflections`	Daily reflection records
0005	`patterns`	Cross-day theme clusters
0006	`contradictions`	Episode-pair disagreements + Wilson CI
0007	`calibration_buckets`	(task_type, project) declared vs verified counts
0008	`mistakes`	Anchored correction log
0009	`reasoning_templates`	Extracted reasoning step sequences
0010	`should_have_asked`	Questions the agent should have asked up front
0011	`ask_backs`	System-drafted clarifying questions for next session

All projects share the same pool. Cross-project routing is controlled by each episode's ValidityScope (see below) — not by separate storage.

Configuration

All knobs live in ~/.tempera/config.toml. The defaults are tuned to be useful out of the box; you only need to touch this if you want to change retrieval ranking, dream-cycle behavior, or per-phase budgets.

`Crate { name, version }`	0.020	~35 days
`Workaround { ref, expires }`	0.050	~14 days
(no scope set, legacy)	0.010	~70 days

Under the Hood

Multi-hop Bellman Propagation

Value from helpful episodes spreads through the similarity graph in multiple hops:

code

Hop 0: Source episodes (high helpfulness, ≥2 retrievals)
  │
  ▼  γ¹ discount
Hop 1: Similar episodes updated
  │
  ▼  γ² discount
Hop 2: Episodes similar to hop-1 updated
  │
  ▼  Converges when no updates occur

Session Chaining

Episodes captured within 2 hours of each other in the same project are automatically linked:

code

Session abc123:
  ├── Episode 1: "Investigated auth bug" (debug)
  ├── Episode 2: "Found root cause in token validation" (research)
  └── Episode 3: "Fixed token expiry check" (bugfix, success)
       ↓
  Temporal credit flows back to episodes 1 & 2
  Session-linked propagation boosts all 3

The Dream Cycle (v0.7)

A budgeted background pipeline that runs nightly (or on demand). Each phase shares a CostBudget; free phases ignore it, paid phases check try_spend() before each LLM call.

code

verify_advance  →  decay  →  reflect  →  patterns  →  contradict  →  templates
   (free)         (free)   (Sonnet)    (Sonnet)    (Haiku)        (Sonnet)
                          ↓             ↓            ↓             ↓
                  reflections/  patterns/   contradictions  templates/

verify_advance: bumps episodes from Merged to StableNoRevert after stable_threshold_days.
decay: scope-aware utility decay (see table above).
reflect: Haiku triage gates Sonnet authorship; high-signal days get a reflection page.
patterns: agglomerative clustering on reflection embeddings → cross-day themes.
contradict: pairs frequently-retrieved BKM episodes and asks Haiku whether they disagree on a factual claim; surfaces a Wilson 95% CI on the contradiction rate.
templates: groups successful verified episodes by (task_type, domain), extracts reusable step sequences via Sonnet.

Worst case per full cycle: roughly $0.50 with default settings.

Scoring Formula

Retrieval ranking combines three signals with normalized weights:

code

score = (sim_w × similarity + util_w × utility + rec_w × recency) / (sim_w + util_w + rec_w)

Default in hybrid mode: 85% similarity (RRF-normalized over vector + BM25), 15% utility, 0% recency. The VerificationState of each episode multiplies into salience — well-verified successes weigh more.

Cross-project routing (v0.10)

Every claim carries a ValidityScope that determines:

Decay rate (table above).
Transferability: is_transferable() returns true for everything except Project { name }. The retrieve and brief surfaces use this to decide what surfaces when the agent opts into cross_project=true.

Legacy episodes captured before v0.6.4 don't have a scope set, so they stay project-bound by default. New captures (v0.10.3+) get a scope suggested automatically by the intent-extraction LLM call — using a colon-encoded format like language:rust, crate:sqlx@0.8, domain:async-rust, workaround:repo#123, or project. The default when in doubt is project, keeping the system conservative.

Maintenance

Run periodically to keep memory healthy:

bash

# Nightly: dream cycle (verify_advance + decay + reflect + patterns + contradict + templates)
tempera dream --max-usd 0.50

# Weekly: Propagate utility values (multi-hop with convergence)
tempera propagate --temporal

# Monthly: Clean up old/useless episodes
tempera prune --older-than 90 --min-utility 0.2 --execute

# As needed: Check trends
tempera trends

# As needed: Review and consolidate
# (via MCP) tempera_review(action: "consolidate")

# As needed: health check + auto-remediate
tempera doctor --remediate --yes

The dream cycle is the load-bearing piece for long-running memory hygiene. It uses Haiku for cheap gating and Sonnet for authorship — the default $0.50 cap is the worst case across every phase.

Environment Variables

Variable	Description
`ANTHROPIC_API_KEY`	For LLM-based intent extraction (`--extract-intent`)
`TEMPERA_DATA_DIR`	Override default data directory
`FASTEMBED_CACHE_DIR`	Override embedding model cache location

Troubleshooting

MCP server not loading

Check path: ls /path/to/tempera-mcp
Check config: cat ~/.claude.json
Restart Claude Code completely
Run /mcp to verify

Embeddings slow on first run

The BGE-Small model (~128MB) downloads on first use from HuggingFace. This requires internet access. After download, the model is cached at ~/.tempera/models/ and works offline.

Vector search not finding anything

Run tempera index to create/update the vector database.

Model download fails

If behind a firewall or proxy, ensure access to huggingface.co. The model files are downloaded via HTTPS.

`tempera_brief` returns "nothing to surface"

This is normal early on — the brief joins against signal data (mistakes, asks, templates, calibration) that accrues over time. Specifically:

The mistakes / should-have-asked sections only fire when the files you pass overlap with previously-logged rows.
The template section only fires when at least 3 successful verified episodes share the (task_type, domain) pair (templates accrue during the dream cycle).
The calibration warning needs ≥5 declared-success captures in the bucket before it surfaces.

Fall back to tempera_retrieve for episode-level recall.

`tempera retrieve --cross-project` finds nothing

Episodes captured before v0.6.4 don't have a ValidityScope set, and v0.10's cross-project filter treats unscoped claims as project-bound (conservative default). Either (a) capture new episodes with v0.10.3+, which auto-suggests a scope, or (b) manually classify legacy episodes via the MCP validity_scope parameter on capture.
