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 | $0.00025 | $0.00290 |
| Opus 5.5 | $0.00010 | $0.00116 |
| Sonnet 5.5 | $0.00005 | $0.00058 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
add-spec-feature 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 8d 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.
What it actually says
Add or change an MCP spec feature
Connecta targets MCP revision 2026-07-28 and its official extensions. spec/coverage.json records current support. Describe unimplemented work as planned.
Each feature has id, status, a https://modelcontextprotocol.io/ spec
URL and non-empty notes. Supported or partial claims link evidence: an
array of executable files under test/, eval/ or src/providers/. Partial
notes name the gaps. Planned or declined features link an issue or decision.
The revision's feature inventory remains in
test/spec-coverage.node.test.ts.
Change that inventory with a spec revision.
Read PRINCIPLES.md and the owning contract first. Follow AGENTS.md's test policy for outcome journeys, focused fault probes and runtime selection.
Update the feature's status, notes, evidence paths and gap links together. Follow AGENTS.md for checks and its conventions for the change fragment and API boundaries.
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.

add-spec-feature is a skill published in the GitHub repository zackbart/connecta (0 stars, last pushed yesterday), licensed MIT. It adds 25 tokens to every session and 290 once invoked, about $0.0001 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 2026-10-08.
