sheal

your ai agent keeps making the same mistakes. sheal fixes that.

Install • Quick Start • Commands • How It Works • Agents

A CLI toolkit that analyzes AI coding sessions to extract learnings, detect failure patterns, and continuously improve agent behavior.

Your AI agent has amnesia. Every session it repeats the same mistakes, burns the same tokens, forgets the same rules. sheal closes the loop — it reads your sessions, extracts the patterns, writes rules back to your agent config, and makes the next session smarter. It compounds.

Install

npm install -g @liwala/sheal

Or from source:

git clone https://github.com/liwala/sheal
cd sheal
npm install
npx tsc
npm link

Quick Start

# Health check your project setup
sheal check

# Audit your Claude Code settings (permissions, hooks, MCPs)
sheal audit

# Run a retrospective on your latest session
sheal retro

# See your token spend per project
sheal cost

# Get a categorized digest of what you worked on
sheal digest --since "7 days"

# Ask a question across all your sessions
sheal ask "what went wrong with beads?" --agent claude

# Add a learning from experience
sheal learn add "Always inspect real data before writing parsers" --tags=parsing

Commands

`sheal check`

Pre-session health check. Detects environment issues before you start coding.

sheal check                    # Pretty output
sheal check --format json      # JSON output
sheal check --skip performance # Skip specific checkers
sheal check --strict           # Warnings are blockers: exit non-zero on any warning

Checkers: git status, dependencies, tests, environment, session learnings, performance & efficiency, Claude Code settings.

`sheal guard`

Point-in-time gates compiled from learnings, designed for hooks and CI.

sheal guard pr                 # Pre-PR gate: branch must be ahead of base, exit 1 otherwise
sheal guard pr --base develop  # Non-main base branch

guard pr verifies HEAD is a working branch (not the base itself), that git rev-list base..HEAD is non-empty (an empty PR is always a mistake), and warns on uncommitted changes. Wire it into a PreToolUse hook on gh pr create or a CI step.

The performance checker detects your AI agent (Claude Code, Cursor, Gemini, Copilot, Amp), checks for RTK token compression, and config file sizes. The claude-settings checker audits permissions, hooks, MCP servers, env vars, and plugins across all settings scopes.

`sheal audit`

Audit Claude Code settings across all scopes — permissions, hooks, MCP servers, environment variables, and plugins.

sheal audit                    # Pretty output
sheal audit --format json      # JSON output
sheal audit -p /path/to/project  # Different project root

Reads from all four settings files (global, global-local, project, project-local) and shows a merged view of what's configured where.

`sheal retro`

Session retrospective. Analyzes the most recent AI coding session for failure loops, wasted effort, and learnings.

sheal retro                        # Static analysis (latest session)
sheal retro --checkpoint <id>      # Specific session
sheal retro --enrich               # LLM-enriched deep analysis
sheal retro --enrich --agent amp   # Use a specific agent CLI
sheal retro --prompt               # Output raw prompt (pipe to any LLM)
sheal retro --format json          # JSON output

The --enrich flag invokes an agent CLI to perform deep analysis on top of the static retro. The agent extracts rules and offers to save them as learnings. Results are cached at .sheal/retros/.

`sheal ask <question>`

Query across your session transcripts using natural language. Uses a 3-phase pipeline:

Extract search terms from your question (agent-assisted, with local fallback)
Local grep across sessions using those terms (word-boundary matching)
Agent analyzes relevant excerpts to answer your question (falls back to raw excerpts)

# Search current project's sessions
sheal ask "what went wrong with beads?"

# Use a specific agent for analysis
sheal ask "how did we handle the auth migration?" --agent codex

# Search ALL projects globally
sheal ask --global "what patterns keep causing test failures?"

# Search a different project
sheal ask -p /path/to/other-project "what happened with the auth migration?"

# Search more sessions
sheal ask "show me all test failures" -n 20

Options:

--agent <name> — Agent CLI to use: claude, gemini, codex, amp
-n, --limit <count> — Max sessions to search (default: 10)
--global — Search across ALL projects in ~/.claude/projects/
-p, --project <path> — Project root to search (default: current directory)

Previously saved results can be browsed:

sheal ask-list              # List saved results
sheal ask-list --global     # List global results
sheal ask-show "beads"      # Show a specific saved result

`sheal browse`

Interactive TUI to explore sessions, retrospectives, and learnings across all your projects.

sheal browse                       # Full TUI (project list)
sheal browse sessions              # Jump to sessions view
sheal browse retros                # Jump to retros view
sheal browse learnings             # Jump to learnings view
sheal browse digests               # Browse digest reports
sheal browse -p myproject          # Pre-filter by project name
sheal browse --agent codex         # Pre-filter by agent

Supports Claude Code, Codex, Amp, and Entire.io sessions. Claude and Codex sessions that are visible in the live home directories but not yet present in .sheal/sessions/raw/ are marked as not backed up, and the sessions view offers to add them to the registry.

`sheal sessions import`

Import Claude Code and Codex transcripts from live home directories, or from an explicit source root, into the current project's raw session registry.

sheal sessions import              # Import from ~/.claude and ~/.codex
sheal sessions import --source /tmp/agent-home
sheal sessions import --format json

Imported sessions are written to .sheal/sessions/raw/<stable-session-id>/ with manifest.json, transcript.raw.jsonl, and normalized.json. Live-home and explicit-source imports do not create pull staging ingested.json markers.

`sheal export`

Export session data as JSON for scripting and piping.

sheal export                       # List sessions (current project)
sheal export --checkpoint <id>     # Export a specific checkpoint
sheal export --global              # Export all projects and sessions

`sheal pull`

Acquire local sandbox changes into sheal's staging area. The shipped local path supports sbx sandboxes and Docker containers, capturing git diff, agent artifacts, and transcripts from runtime home directories when present. Missing agent-specific transcript paths are reported as gaps in the pull output and provenance. Agent home artifacts are discovered by probing supported agent directories under the sandbox user's home directory ($HOME/.claude, $HOME/.codex, $HOME/.copilot, $HOME/.cursor, $HOME/.docker-agent, $HOME/.droid, $HOME/.gemini, $HOME/.kiro, and $HOME/.opencode). Missing home probes are ignored. Transcripts are pulled from known agent home paths such as $HOME/.claude/sessions.jsonl, $HOME/.claude/history.jsonl, $HOME/.claude/projects/<project-slug>/, and $HOME/.codex/sessions/ when present. Workspace files such as AGENTS.md, MEMORY.md, and .sheal/session.jsonl are not part of the pull capture contract.

sheal pull --list                  # List available sbx sandboxes and Docker containers
sheal pull sbx <name>              # Pull one sbx sandbox to ~/.sheal/pulls/
sheal pull sbx <name> --checkpoint # Write a checkpoint stage without registry import
sheal pull --checkpoint-run        # Run configured checkpoint targets once
sheal pull sbx --all               # Pull every sbx sandbox with a workspace
sheal pull docker <name>           # Pull one Docker container selected from --list

Use sheal pull --list first to copy the exact sandbox or container name. Docker selection is intentionally human-driven, so sheal pull docker --all is not supported. Pull acquisition output lands under ~/.sheal/pulls/<backend>/<name>/<timestamp>/ unless pull.stagingDir overrides it. Pulled Claude and Codex transcripts are normalized into the project-local raw registry at .sheal/sessions/raw/<stable-session-id>/; the pull staging directory gets an ingested.json marker pointing at the raw session IDs.

Use --checkpoint with sheal pull <backend> <name> for a manual mid-session capture before teardown. Checkpoint mode uses the same local adapter capture set and staging root, writes checkpoint.json, stamps provenance with captureKind: "checkpoint", and does not normalize transcripts into the raw registry or write an ingested.json marker. Long-running daemon scheduling is a future layer over this manual checkpoint primitive.

Use --checkpoint-run to run a one-shot checkpoint pass over explicitly configured local targets:

{
  "pull": {
    "checkpointTargets": [
      { "backend": "sbx", "name": "codex-before-teardown" }
    ]
  }
}

The runner never implies --all: only pull.checkpointTargets are checkpointed, unconfigured sandboxes are ignored, and checkpoint stages still do not import into the raw registry.

`sheal init`

Bootstrap sheal awareness into your project's agent configuration files (CLAUDE.md, .cursorrules, etc.).

sheal init                         # Add sheal instructions to agent configs
sheal init --dry-run               # Preview changes without writing

`sheal graph`

Cross-session knowledge graph showing file hotspots, agent activity, and patterns.

sheal graph                        # Pretty-print graph summary
sheal graph --file src/index.ts    # History for a specific file
sheal graph --agent claude         # Details for a specific agent
sheal graph --json                 # JSON output

`sheal digest`

Categorized digest of all your prompts across agents. See what you actually worked on.

sheal digest                           # Last 7 days, pretty output
sheal digest --since "1 month"         # Custom window
sheal digest --enrich                  # LLM-powered categorization (Haiku)
sheal digest --compare                 # Diff against previous digest
sheal digest -p myproject              # Filter to one project
sheal digest -f markdown -o report.md  # Export as markdown

The --enrich flag uses Haiku to smart-categorize prompts that rule-based matching missed. The --compare flag finds the previous digest for the same scope and shows what changed.

`sheal cost`

Token cost dashboard — see exactly where your Claude budget goes.

sheal cost                             # Last 7 days
sheal cost --since "1 month"           # Custom window
sheal cost -p myproject                # Single project
sheal cost --plan "Max 5x"            # Compare against your plan
sheal cost --format json               # JSON output for scripting

Shows per-model breakdown, per-project spend, project-by-model matrix, cost type split (input/output/cache-read/cache-write), and subscription savings vs Pro / Max 5x / Max 20x plans.

`sheal weekly`

Full weekly report — runs digest + cost together, optionally with deep Claude analysis and Slack delivery.

sheal weekly                           # Digest + cost for last 7 days
sheal weekly --agent                   # Add deep LLM analysis
sheal weekly --slack                   # Post summary to Slack
sheal weekly --plan "Max 20x"          # Include plan savings

Reports are saved to ~/.sheal/weekly-digests/ for historical tracking.

`sheal drift`

Detect when learnings aren't being applied in recent sessions. Compares your active learnings (both global and project-scoped) against session data to find patterns that should have been prevented but weren't.

sheal drift                        # Check learnings against last 10 sessions
sheal drift -n 20                  # Check against more sessions
sheal drift -p /path/to/project    # Different project root
sheal drift --json                 # JSON output

Each drifted learning is labeled [global] or [project] so you can see where the violation originated. Severity dots indicate how often the learning was violated (● once, ●● twice, ●●● three or more times).

Detection methods:

Keyword matching — compares session retro learnings against your active learnings
Failure loop detection — flags retry-related learnings when retries recur
File churn detection — flags planning-related learnings when wasted edits recur
Enrichment parsing — reads Recurring sections from LLM-enriched retros

`sheal learn`

Manage ADR-style session learnings. Learnings are stored as individual markdown files with frontmatter metadata.

# Add a learning (saves to project by default)
sheal learn add "Always check bd --help before guessing flags" \
  --tags=beads,cli --category=workflow --severity=high
sheal learn add --global "..."  # Save directly to global store

# List learnings
sheal learn list              # Project learnings (.sheal/learnings/)
sheal learn list --global     # Global learnings (~/.sheal/learnings/)
sheal learn list --tag=beads  # Filter by tag

# Review & curate learnings interactively
sheal learn review              # Project learnings (drafts shown first)
sheal learn review --global     # Global learnings

# Promote curated project learnings to global
sheal learn promote

# Pull global learnings into project (by tag match)
sheal learn sync

# Corpus hygiene: duplicate IDs, near-duplicate rules, missing triggers
sheal learn lint                # Exit 1 on findings (CI-usable)
sheal learn lint --format json

# Consolidation pass: emit a reviewable change set (never mutates the store)
sheal consolidate               # Writes .sheal/consolidation/<date>-change-set.md
sheal consolidate --format json # Mechanical change set to stdout
sheal consolidate --prompt      # LLM judgment-stage prompt — pipe to any agent CLI

Git-based backup & sync

Back up ~/.sheal/ to a git repo for cross-machine sync and team sharing. By default backs up learnings, digests, and config. Optionally includes retros from all projects.

# Connect to a remote repo (initializes git in ~/.sheal/)
sheal backup remote add git@github.com:you/sheal-data.git

# Push (learnings + digests + config)
sheal backup push

# Also gather retros from all projects
sheal backup push --include retros

# Pull from remote
sheal backup pull

# Show or disconnect
sheal backup remote show
sheal backup remote remove

# learn push/pull are aliases for backup push/pull
sheal learn push
sheal learn pull

Human-in-the-loop curation

Learnings are never auto-accepted. Every learning goes through human review before it can influence agent behavior:

sheal retro --enrich — the LLM extracts candidate rules from the session
Saved as drafts — rules land in .sheal/learnings/ with status: draft
Interactive review — you accept, edit, or reject each draft on the spot
Active learnings — accepted rules become status: active and show up in sheal learn list
sheal learn promote — lift project learnings to your global store (~/.sheal/learnings/)
sheal learn sync — pull relevant global learnings back into other projects
sheal rules — inject active learnings into agent config files (AGENTS.md, .cursorrules)

You can also add learnings manually (sheal learn add "...") or review remaining drafts later (sheal learn review).

The full lifecycle:

retro → project drafts → review → active → promote → global ─┐
             ▲               │                       digests ──┤
             │          human accepts                 config  ──┼─ backup push → remote
        learn add       edits, or rejects             retros  ──┘  backup pull ← remote
                                                      global ──── sync → project

Learning format (~/.sheal/learnings/LEARN-001-inspect-real-data.md):

id: LEARN-001
title: Inspect real data before writing parsers
date: 2026-03-13
tags: [parsing, external-data, general]
category: missing-context
severity: high
status: active
---

Before writing parsers for external data formats, always inspect 2-3 real
samples first. Don't rely solely on documentation or type definitions.

Categories: missing-context, failure-loop, wasted-effort, environment, workflow

Session Sources

sheal supports two session data sources with automatic fallback:

Native Claude Code — reads JSONL transcripts directly from ~/.claude/projects/ (default)
Entire.io — reads from the entire/checkpoints/v1 git branch (rich metadata, AI summaries, attribution)

Supported Agents

For --enrich and ask commands, sheal can invoke these agent CLIs:

Agent	CLI Command	Invocation
Claude Code	`claude`	`claude -p --output-format text` (stdin)
Codex	`codex`	`codex exec -` (stdin)
Amp	`amp`	`amp -x` (stdin)
Gemini CLI	`gemini`	stdin pipe

Use --agent claude, --agent codex, --agent amp, or --agent gemini to pick one. Auto-detection tries the session's own agent first, then falls back to any available CLI.

How It Works

Session Capture (Entire.io / Claude Code native)
    |  session transcripts, diffs, metadata
    v
Self-Healing Engine (sheal)
    |  failure patterns, learnings, rules
    v
Agent Configuration (CLAUDE.md, .cursorrules, etc.)
    |  improved behavior
    v
Next Session (fewer mistakes)

Configuration

sheal reads an optional .self-heal.json from the project root (or the nearest ancestor directory). It configures checkers and pull staging, e.g.:

{
  "checkers": {
    "tests": { "timeoutMs": 30000 },
    "environment": {
      "requiredVars": ["DATABASE_URL"],
      "requiredServices": [{ "name": "postgres", "check": "pg_isready -p 5432" }]
    }
  }
}

A .self-heal.local.json next to it (gitignored) is merged over the shared config field by field — use it for machine-local checks and private tooling that don't belong in the repo.
