strata:propose

A way to record an unresolved question or disagreement as a time-bounded proposition. It tracks the question from open, through competing views, toward a settled answer.

In plain words
What is it for?
Use it when the team is unsure about an important choice, after checking whether the question or a related decision is already recorded.
Why use it?
It prevents uncertain decisions from being forgotten, duplicated, or treated as settled before there is enough evidence.

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.

Security

Grade A, and why

strata:propose 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 3d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

strata:propose

The "open question" scope. Closes the gap between what we know (domain), what we've chosen (decisions), what we did (pr-context), and what we did wrong (lessons), with a fourth: what we're still Figuring out.

When to use

Situation Skill
Open question, multiple positions, no choice yet strata:propose
Chosen option with reasoning strata:decide
Stable concept / vocabulary strata:domain
Retrospective fact strata:save --scope lessons
In-flight branch work strata:save

A proposition is explicitly time-bounded. It exists to be resolved. A proposition that never gets settled or refuted is itself a signal.

How

Recall before you open it

Before creating a proposition, call recall to check it isn't already tracked. Two agents opening the same open question — or re-litigating one that's already decided — is the failure this prevents:

recall(query="<the question, in your words>", scope="propositions", layer=1)

Then run a second pass with scope="decisions". Adjudicate:

  • existing open proposition → add a position to it (below), don't fork.
  • already settled or decided → tell the user and point at the note; write nothing.
  • genuinely new → create it.

Create

cat <<'EOF' | "${CLAUDE_PLUGIN_ROOT}/bin/strata" propose \
    --title "Should we move to Postgres for tenant data?"
# Should we move to Postgres for tenant data?

## What we're trying to figure out
<context — why this is open>

## Positions on the table
- Stay on SQLite: <reasons>
- Move to Postgres: <reasons>

## What evidence would settle this
- <what we'd need to know>
EOF

Default status is open. Pass --status contested if multiple positions are actively defended, or --status converging if one is winning.

Add a position (the debate log)

When someone weighs in on an open proposition, append a position — don't rewrite the note. Each entry is attributed, dated, and append-only:

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:propose is a skill published in the GitHub repository gideondk/strata (5 stars, last pushed 1mo ago), licensed MPL-2.0. It adds 118 tokens to every session and 1,459 once invoked, about $0.0006 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.
