Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00094 | $0.00587 |
| Opus 5 | $0.00047 | $0.00293 |
| Sonnet 5 | $0.00019 | $0.00117 |
| Haiku 4.5 | $0.00009 | $0.00059 |
Grade A, and why
strata:observe scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
strata:observe
The safe autonomous-write lane (see the autonomy-line ADR: gate on reversibility + grounding, never on confidence). An agent may write a grounded, reversible observation without asking — because markdown+git make it trivially revertible and it never ratifies anything.
When to use
- A durable breadcrumb anchored to a real artifact: "commit
abcchanged the token-bucket policy", "billing/owns invoice retries". - Worth keeping, but not worth interrupting the user for, and not a decision.
Never use for: decisions (/strata:decide), contested questions
(/strata:propose), or domain definitions (/strata:domain). Those are
human-ratified — that's the moat. This script structurally cannot write them.
How
Grounding is required — pass --source-file (project-relative, repeatable)
and/or --commit. Ungrounded auto-writes are refused.
echo "Commit bumped the HTTP retry budget 3→5; see the client." | \
"${CLAUDE_PLUGIN_ROOT}/bin/strata" observe \
--topic "retry budget bumped" \
--source-file "src/http/client.py" --commit "$(git rev-parse --short HEAD)"
The note lands in pr-context/<branch>/ with status: auto +
source: git-derived. It announces itself and is quarantined from
recall (it won't surface in /strata:find, the recall tool, or the primer)
until a human reviews it.
The review lifecycle (keep or discard)
Auto-notes pile up in the "Awaiting your input" section of
/strata:dashboard. For each:
- Keep / promote — edit the note and remove the
status: autoline (or change it to a normal status). It then enters recall like any other note. - Discard —
/strata:forget <path>(or just delete the file).
This is "machine proposes, human disposes": capture is automatic, but nothing unreviewed is ever served as canonical memory.
What this file has done since we first saw it
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.

strata:observe is a skill published in the GitHub repository gideondk/strata (5 stars, last pushed 1mo ago), licensed MPL-2.0. It adds 94 tokens to every session and 587 once invoked, about $0.0005 per session on Opus 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.
