A recording step for saving signals such as chat sessions, pasted text, or connector data into a knowledge system's source folder. Each capture is immutable, meaning it is preserved and not edited later.

It helps capture Claude Code sessions, pasted content, and data pulled from connectors. It records the source only; creating or combining knowledge entries is handled elsewhere.

It gives incoming information a permanent record with its origin and time. It prevents raw evidence from being confused with edited knowledge or summaries.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00065	$0.00844
Opus 5.5	$0.00026	$0.00338
Sonnet 5.5	$0.00013	$0.00169
Haiku 4.5	$0.00006	$0.00084

Security

Grade A, and why

lw-capture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

lw-capture

Append a signal to the world model's sources/ — immutable, append-only, provenance-stamped. This skill is the record primitive of the living loop — mostly invisible: the connectors (forged by lw-forge) and the surface automations (the Claude Code hook, the claude.ai routine) call it; you rarely invoke it by hand. When you do invoke it directly — /lw-capture with a paste or a file — it writes one immutable digest capture to sources/ and stops there. It does not create or edit knowledge nodes and does not consolidate — that is lw-enrich (propose-don't-apply). Loads ontology/contract.md.

What it writes — a capture (a `source` node)

One markdown file per signal, under sources/<channel>/…, with frontmatter:

---
id: <stable id — derived from the source's native id, so re-runs don't duplicate>
type: source
title: <human label for the signal>
timestamp: <when the signal happened, ISO 8601>
resource: <link or native id of the original — the system of record>
lookward:
 world_model: <wm name>
 purpose: "raw capture of a <source kind>"
 face: self
 visibility: private # default private (Rule 3)
 provenance: connector # connector | upload | reflection | session
 confidence: high
 capture:
 surface: <claude.ai | claude-code | …>
 source_kind: <session-transcript | message | file | …>
 source_id: <native id>
 pull_run: <ISO date of this capture run>
---
# Faithful digest of the signal — topics, decisions, artifacts produced, open items,
# entities mentioned. Every claim traceable to `resource`. Nothing invented (citation invariant).

Rules (from the contract)

Append-only & immutable. Never edit or overwrite a prior capture. Re-running is idempotent: if a capture for this source_id already exists, skip it.
Faithful, not invented. The digest reflects only what the signal contains; it cites the source. No consolidation, no interpretation into nodes.
Default private. visibility: private unless the user has set otherwise.
Provenance always. Stamp surface, source kind, source id, and pull-run.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lw-capture is a skill published in the GitHub repository matteoroversi/lookward (7 stars, last pushed 4mo ago), licensed MIT. It adds 65 tokens to every session and 844 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
