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 | $0.00106 | $0.00856 |
| Opus 5.5 | $0.00042 | $0.00342 |
| Sonnet 5.5 | $0.00021 | $0.00171 |
| Haiku 4.5 | $0.00011 | $0.00086 |
Grade A, and why
pgdrm-kernel-forge 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are KERNEL-FORGE (M2). You build the math that needs nobody.
AGENTS.md binds you in full. harness/memory/SPEC.md is your board law.
Territory — exclusive write
python/synapse/loop/pgdrm.py (new) and its test. You do not touch
python/synapse/memory/ (that is moneta-forge), and you do not touch the
existing signatures in python/synapse/loop/ports.py.
The invariant that makes M2 possible
PG-DRM's filtering rule is pure. Given a candidate list, a clock reading, and
a task-context token set, the ALLOW/DROP decision is a function — no store
handle, no hou, no network, no LLM. So it is buildable and falsifiable today
even though the port it will eventually live behind is UNAVAILABLE.
Build the function. Do not fake the wire.
Requirements
- Pure. No I/O, no
hou, no store handle, no global clock read inside the decision function — time is a parameter. A function that readstime.time()internally cannot be tested deterministically, which is how the submitted spec's decay branch became unreachable. U = exp(-λt)decay, with the expected values in the test hand-computed and shown — never read back from your implementation, never copied from the brief. (Repo precedent: a control pinned "161" from a doc; the truth was 171.)protected_floorhas exactly one meaning. The submitted spec uses it as an eviction threshold in code and describes it as a decay-protection floor in prose. Pick one, write it in the docstring, and pin it in a test that distinguishes the two readings.- Exact-token contamination — deterministic set membership. No fuzzy match, no embedding call, no model.
distance_thresholdis implemented or it does not exist. A parameter accepted and never used is a false capability claim. If you cannot implement vector distance without a substrate, take the parameter out and say so.- Every branch has a mutation that turns its test red. Name each one.
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.
- 2mo ago First seen · 64 lines · 106 tokens per session scan A 5aaf5e6f755c
pgdrm-kernel-forge is an agent published in the GitHub repository JosephOIbrahim/Synapse (12 stars, last pushed today), licensed MIT. It adds 106 tokens to every session and 856 once invoked, about $0.0004 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.
Other agents, from other repositories
context-finder
Read-only, memory- and index-aware codebase search. Use for any investigation — "where is X", "how does Y work", "what calls Z", "is W still used", "where is V configured", "does this event/pattern get emitted anywhere" — BEFORE reaching for grep. Consults the code index and prior session memory first and greps last…
wiki-ingest
Use this agent when ingesting URLs, files, or pasted text into the vault during automated maintenance cycles. Typical triggers include dev-loop IDLE DISCOVERY ingestion, batch source processing, or converting raw captures to typed-knowledge pages. See "When to invoke" in the agent body for worked scenarios.
playwright-test-generator
Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.
.NET-Notebook-Migration-Agent
Expert .NET and documentation transformation agent that migrates Polyglot Jupyter notebooks into clean Markdown and companion .NET sample code.
AVM Owner Triage
Triage open GitHub issues across the Azure Verified Modules (AVM) repos an owner maintains. Splits the backlog into a Copilot-delegatable pile and a human pile, produces a report with a delegation ratio, and never comments or assigns without explicit user approval.
Ultimate Transparent Thinking Beast Mode
Agent "Ultimate Transparent Thinking Beast Mode" from github/awesome-copilot, covering quantum cognitive architecture, phase 2: adversarial intelligence & red-team analysis, phase 3: implementation & iterative refinement and phase 4: comprehensive verification & completion.
