Dogfooded 2026-04-18 on main HEAD 43eac4d from /tmp/cdNN and /tmp/cdOO.
Three related findings on session reference resolution asymmetry:
1. /clear divergence (primary):
- /clear --confirm rewrites session_id inside the file header
but reuses the old filename.
- /session list reads meta header, reports new id.
- --resume looks up by filename stem, not meta header.
- Net: /session list reports ids that --resume can't resolve.
Concrete:
claw --resume ses /clear --confirm
→ new_session_id: session-1776481564268-1
→ file still named ses.jsonl, meta session_id now the new id
claw --resume ses /session list
→ active: session-1776481564268-1
claw --resume session-1776481564268-1
→ ERROR session not found
2. .bak files filtered out of /session list silently:
ls .claw/sessions/<bucket>/
ses.jsonl ses.jsonl.before-clear-<ts>.bak
/session list → only ses.jsonl visible, .bak zero discoverability
is_managed_session_file only matches .jsonl and .json.
3. 0-byte session files fabricate phantom sessions:
touch .claw/sessions/<bucket>/emptyses.jsonl
claw --resume emptyses /session list
→ active: session-<ms>-0
→ sessions: [session-<ms>-1]
Two different fabricated ids, neither persisted to disk.
--resume either fabricated id → 'session not found'.
Trace:
session_control.rs:86-116 resolve_reference:
handle.id = session_id_from_path(&path) (filename stem)
.unwrap_or_else(|| ref.to_string())
Meta header NEVER consulted for ref → id mapping.
session_control.rs:118-137 resolve_managed_path:
for ext in [jsonl, json]:
path = sessions_root / '{ref}.{ext}'
if path.exists(): return
Lookup key is filename. Zero fallback to meta scan.
session_control.rs:228-285 collect_sessions_from_dir:
on load success: summary.id = session.session_id (meta)
on load failure: summary.id = path.file_stem() (filename)
/session list thus reports meta ids for good files.
/clear handler rewrites session_id in-place, writes to same
session_path. File keeps old name, gets new id inside.
is_managed_session_file filters .jsonl/.json only. .bak invisible.
Fix shape (~90 lines):
- /clear preserves filename's identity (Option A: keep session_id,
wipe content). /session fork handles new-id semantics (#113).
- resolve_reference falls back to meta-header scan when filename
lookup fails. Covers legacy divergent files.
- /session list surfaces backups via --include-backups flag OR
separate backups: [] array with structured metadata.
- 0-byte session files produce SessionError::EmptySessionFile
instead of silent fabrication. Structured error, not phantom.
- regression tests per failure mode.
Joins Session-handling: #93 + #112 + #113 + #114 — reference
resolution + concurrent-modification + programmatic management +
reference/enumeration asymmetry. Complete session-handling cluster.
Joins Truth-audit — /session list output factually wrong about
what is resumable.
Cross-cluster with Parallel-entry-point asymmetry (#91, #101,
#104, #105, #108) — entry points reading same underlying data
produce mutually inconsistent identifiers.
Natural bundle: #93 + #112 + #113 + #114 (session-handling
quartet — complete coverage).
Alternative bundle: #104 + #114 — /clear filename semantics +
/export filename semantics both hide identity in filename.

Claw Code
ultraworkers/claw-code · Usage · Rust workspace · Parity · Roadmap · UltraWorkers Discord
Claw Code is the public Rust implementation of the claw CLI agent harness.
The canonical implementation lives in rust/, and the current source of truth for this repository is ultraworkers/claw-code.
Important
Start with
USAGE.mdfor build, auth, CLI, session, and parity-harness workflows. Makeclaw doctoryour first health check after building, userust/README.mdfor crate-level details, readPARITY.mdfor the current Rust-port checkpoint, and seedocs/container.mdfor the container-first workflow.ACP / Zed status:
claw-codedoes not ship an ACP/Zed daemon entrypoint yet. Runclaw acp(orclaw --acp) for the current status instead of guessing from source layout;claw acp serveis currently a discoverability alias only, and real ACP support remains tracked separately inROADMAP.md.

Quick start
Note
[!WARNING]
cargo install claw-codeinstalls the wrong thing. Theclaw-codecrate on crates.io is a deprecated stub that placesclaw-code-deprecated.exe— notclaw. Running it only prints"claw-code has been renamed to agent-code". Do not usecargo install claw-code. Either build from source (this repo) or install the upstream binary:cargo install agent-code # upstream binary — installs 'agent.exe' (Windows) / 'agent' (Unix), NOT 'agent-code'This repo (
ultraworkers/claw-code) is build-from-source only — follow the steps below.
# 1. Clone and build
git clone https://github.com/ultraworkers/claw-code
cd claw-code/rust
cargo build --workspace
# 2. Set your API key (Anthropic API key — not a Claude subscription)
export ANTHROPIC_API_KEY="sk-ant-..."
# 3. Verify everything is wired correctly
./target/debug/claw doctor
# 4. Run a prompt
./target/debug/claw prompt "say hello"
Note
Windows (PowerShell): the binary is
claw.exe, notclaw. Use.\target\debug\claw.exeor runcargo run -- prompt "say hello"to skip the path lookup.
Windows setup
PowerShell is a supported Windows path. Use whichever shell works for you. The common onboarding issues on Windows are:
- Install Rust first — download from https://rustup.rs/ and run the installer. Close and reopen your terminal when it finishes.
- Verify Rust is on PATH:
If this fails, reopen your terminal or run the PATH setup from the Rust installer output, then retry.cargo --version - Clone and build (works in PowerShell, Git Bash, or WSL):
git clone https://github.com/ultraworkers/claw-code cd claw-code/rust cargo build --workspace - Run (PowerShell — note
.exeand backslash):$env:ANTHROPIC_API_KEY = "sk-ant-..." .\target\debug\claw.exe prompt "say hello"
Git Bash / WSL are optional alternatives, not requirements. If you prefer bash-style paths (/c/Users/you/... instead of C:\Users\you\...), Git Bash (ships with Git for Windows) works well. In Git Bash, the MINGW64 prompt is expected and normal — not a broken install.
Note
Auth: claw requires an API key (
ANTHROPIC_API_KEY,OPENAI_API_KEY, etc.) — Claude subscription login is not a supported auth path.
Run the workspace test suite:
cd rust
cargo test --workspace
