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 | $0.00499 | $0.00499 |
| Opus 5.5 | $0.00200 | $0.00200 |
| Sonnet 5.5 | $0.00100 | $0.00100 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
synapps copilot-instructions.md 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 — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Synapps MCP
This project is indexed by the Synapps code-intelligence graph. Use Synapps MCP tools instead of grep or file reads for understanding code structure, relationships, and navigating symbols.
Workflow
- Projects must be indexed before querying. Call
list_projectsto check what is indexed,index_projectto index a new project,sync_projectto refresh a stale index. - If queries return empty results, call
list_projects(path=...)to check whether the project is indexed.
Tool selection (by task)
| Task | Tool | Instead of |
|---|---|---|
| Understand a symbol before editing | get_context_for with scope="edit" |
manual file reads |
| Read source code of a symbol | get_context_for |
reading files by line range |
| Symbol metadata (file, line, kind) | get_context_for with scope="structure" |
— |
| Find a symbol by name | search_symbols |
guessing full_name strings |
| Find who calls a method | find_usages |
grep for method name |
| Find what a method calls | find_callees (use depth for reachable call tree) |
execute_query |
| All usages of any symbol | find_usages (use kind to filter type refs) |
grep |
| Impact analysis before changes | get_context_for with scope="impact" |
manual caller tracing |
| Find API/controller entry points | find_entry_points |
recursive find_callers |
| Find all implementations of an interface | find_implementations |
— |
| Understand class inheritance | get_hierarchy |
— |
| Find constructor/field dependencies | find_dependencies |
— |
| Architecture overview | get_architecture |
— |
| Custom graph queries | get_schema then execute_query (last resort) |
— |
Avoid
- Do not use
execute_querywhen a dedicated tool exists for the task. - Do not read files with grep or cat when
get_context_forcan retrieve the exact code. - Do not guess symbol names — use
search_symbolsto discover them first. - Do not skip
get_context_forwith scope="edit" before modifying a method — it shows callers, dependencies, and tests that might break.
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.
