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 | $0.00040 | $0.02418 |
| Opus 5 | $0.00020 | $0.01209 |
| Sonnet 5 | $0.00008 | $0.00484 |
| Haiku 4.5 | $0.00004 | $0.00242 |
Grade A, and why
trellis-update-spec 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 10d 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.

Update Code-Spec - Capture Executable Contracts
When you learn something valuable (from debugging, implementing, or discussion), use this to update the relevant code-spec documents.
Timing: After completing a task, fixing a bug, or discovering a new pattern
Code-Spec First Rule (CRITICAL)
In this project, "spec" for implementation work means code-spec:
- Executable contracts (not principle-only text)
- Concrete signatures, payload fields, env keys, and boundary behavior
- Testable validation/error behavior
If the change touches infra or cross-layer contracts, code-spec depth is mandatory.
Mandatory Triggers
Apply code-spec depth when the change includes any of:
- New/changed command or API signature
- Cross-layer request/response contract change
- Database schema/migration change
- Infra integration (storage, queue, cache, secrets, env wiring)
Mandatory Output (7 Sections)
For triggered tasks, include all sections below:
- Scope / Trigger
- Signatures (command/API/DB)
- Contracts (request/response/env)
- Validation & Error Matrix
- Good/Base/Bad Cases
- Tests Required (with assertion points)
- Wrong vs Correct (at least one pair)
When to Update Code-Specs
| Trigger | Example | Target Spec |
|---|---|---|
| Implemented a feature | Added a new integration or module | Relevant spec file |
| Made a design decision | Chose extensibility pattern over simplicity | Relevant spec + "Design Decisions" section |
| Fixed a bug | Found a subtle issue with error handling | Relevant spec (e.g., error-handling docs) |
| Discovered a pattern | Found a better way to structure code | Relevant spec file |
| Hit a gotcha | Learned that X must be done before Y | Relevant spec + "Common Mistakes" section |
| Established a convention | Team agreed on naming pattern | Quality guidelines |
| New thinking trigger | "Don't forget to check X before doing Y" | guides/*.md (as a checklist item) |
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.
- 10d ago First seen · 357 lines · 40 tokens per session scan A 003ce08a3404
trellis-update-spec is a skill published in the GitHub repository yuqie6/ProductFlow (302 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 2,418 once invoked, about $0.0002 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 2026-08-30.
