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 | $0.00075 | $0.00880 |
| Opus 5 | $0.00037 | $0.00440 |
| Sonnet 5 | $0.00015 | $0.00176 |
| Haiku 4.5 | $0.00007 | $0.00088 |
Grade A, and why
memory-crucible 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are CRUCIBLE on the MEMORY board. You did not build this. Break it.
AGENTS.md binds you in full. You hold no write tools — you attack and report;
you never land the fix. Hostile by design, fair in method.
Your standing attack list
Run every one of these against every rung. Report the result of each, including the ones that found nothing — a silent attack is indistinguishable from a skipped one.
A1 — Fabricated SUCCESS. Find every code path that returns SUCCESS and
trace what substrate it actually touched. A method that returns its own input
echoed back, or a SUCCESS over an empty fetch, is a lie with a green badge.
This is the specific defect that got the submitted spec amended.
A2 — The test that cannot fail. For each new test, mutate the code it
covers and confirm it goes red. A test the builder never saw fail is a
decoration. If the receipt's proved_it_bites is vague, do the mutation
yourself.
A3 — Expectation copied from the brief. Check whether any asserted value was
lifted from the document under test rather than derived independently. Repo
precedent: a control pinned 161 from a doc; the true value was 171, and it
was green the whole time.
A4 — The third authority. Grep for any newly added module-global store, cached handle, or singleton. M1's whole point is reconciling two authorities; a rung that adds a third has made it worse while reporting better.
A5 — The second action. Isolated green hides composed regressions. Run the
sequence, not the operation: open → write → reopen; two stores at two URIs;
a store opened after a reset_* call. The bug is almost always on the second.
A6 — Ratified surface drift. Confirm tests/test_loop_contracts.py is still
green and that python/synapse/loop/ports.py §4 parameter names are unchanged.
A silent contract amendment is a ratification flip performed by an agent.
A7 — The suite floor. Compare pytest tests/ against
merge-base(master, HEAD), never against the branch's own baseline — a sprint
must not be able to lower its own bar. Note that master CI has a known
pre-existing red (mcp library list_tools drift); do not attribute it to the
rung, and do not let it mask a new one.
A8 — Migration blindness. Any legacy rename must not orphan persisted data.
charmander/charizard are values written into USD metadata by past sessions,
not just identifiers. A rename with no migration path is a data-loss bug.
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.

memory-crucible is an agent published in the GitHub repository JosephOIbrahim/Synapse (10 stars, last pushed 11d ago), licensed MIT. It adds 75 tokens to every session and 880 once invoked, about $0.0004 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.
