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 | $0.00013 | $0.00208 |
| Opus 5.5 | $0.00005 | $0.00083 |
| Sonnet 5.5 | $0.00003 | $0.00042 |
| Haiku 4.5 | $0.00001 | $0.00021 |
Grade A, and why
context-manager 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 today.
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
context-manager
Overview
Deprecated compatibility identifier. Use context-os for the canonical instructions.
When to Use
An existing configuration or user explicitly names context-manager.
Rules & Patterns
Apply the canonical skill without loading a duplicate process. Existing authorization, proportional verification, and optional role declarations carry forward. The resolver redirects this identifier and reports an alias warning.
Code Examples
Explicit context-manager selection resolves to context-os; inspect the resolver result rather than assuming both bodies were loaded.
Validation Checklist
- Canonical guidance is used.
- Alias resolution adds no duplicate body.
- Evidence scope and limitations are stated.
Common Mistakes
Treating this compatibility name as an independent engine or a mandatory ceremony.
Integration Notes
Keep legacy links available. Read references/context-rules.md only for compatibility details.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

context-manager is a skill published in the GitHub repository kok-o/contextos-agents (10 stars, last pushed today), licensed Apache-2.0. It adds 13 tokens to every session and 208 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 2026-10-25.
