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 | $0.00049 | $0.00757 |
| Opus 5.5 | $0.00020 | $0.00303 |
| Sonnet 5.5 | $0.00010 | $0.00151 |
| Haiku 4.5 | $0.00005 | $0.00076 |
Grade A, and why
plan-epic 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 7d 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planning a Synapse feature
Start with the user's request and the active GitHub issue. Read AGENTS.md and DEV.md for conventions and checks. Use README.md and UPGRADE.md for supported behavior and migration constraints.
Gather evidence
- Read the issue's goal, scope, acceptance criteria, and relevant discussion. User instructions take precedence; identify unresolved contradictions rather than silently expanding scope.
- Inspect current source and tests before proposing new helpers or abstractions. Consult closed issues and merged PRs for earlier decisions when relevant.
- Verify SDK facts against the installed/tagged source.
references/is read-only research material and may be stale; record the version inspected. Use released APIs, not assumptions from an unreleased branch. - For UI work, reuse the component layers and tokens documented in AGENTS. Consult Figma only when the feature has a relevant design; record the exact design reference and distinguish it from an implementation choice.
- Read
config/synapse.phpfor current keys. Propose new configuration only when the feature needs it.
Write a focused plan
Scale detail to the task. A small change needs a short plan; a substantial feature should cover:
- Goal and scope: user-visible outcome, issue link, acceptance criteria, and explicit exclusions.
- Evidence and decisions: SDK version/APIs, current implementation, and material tradeoffs or uncertainties.
- Implementation sequence: concrete steps, affected classes/components/routes/storage, and verification for each step. Reuse existing primitives before adding new ones.
- Contracts and migration: request/response shapes, persistence, replay, and upgrade behavior only where changed. Synapse never modifies SDK conversation tables.
- Tests: map acceptance criteria to feature tests and, for UI/chat changes, browser tests. Automated browser tests use faked agents. Verify real HTTP flushing separately if streaming mechanics change.
- Risks and completion: unresolved decisions, relevant regression coverage, documentation updates, and the applicable gates from DEV.
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.

plan-epic is a skill published in the GitHub repository RedberryProducts/synapse (65 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 757 once invoked, about $0.0002 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 2026-08-30.
