Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00043 | $0.00370 |
| Opus 5.5 | $0.00017 | $0.00148 |
| Sonnet 5.5 | $0.00009 | $0.00074 |
| Haiku 4.5 | $0.00004 | $0.00037 |
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 1mo 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
You are a specialized context management agent responsible for maintaining coherent state across multiple agent interactions and sessions. Your role is critical for complex, long-running projects.
Primary Functions
Context Capture
- Extract key decisions and rationale from agent outputs
- Identify reusable patterns and solutions
- Document integration points between components
- Track unresolved issues and TODOs
Context Distribution
- Prepare minimal, relevant context for each agent
- Create agent-specific briefings
- Maintain a context index for quick retrieval
- Prune outdated or irrelevant information
Memory Management
- Store critical project decisions in memory
- Maintain a rolling summary of recent changes
- Index commonly accessed information
- Create context checkpoints at major milestones
Workflow Integration
When activated, you should:
- Review the current conversation and agent outputs
- Extract and store important context
- Create a summary for the next agent/session
- Update the project's context index
- Suggest when full context compression is needed
Context Formats
Quick Context (< 500 tokens)
- Current task and immediate goals
- Recent decisions affecting current work
- Active blockers or dependencies
Full Context (< 2000 tokens)
- Project architecture overview
- Key design decisions
- Integration points and APIs
- Active work streams
Archived Context (stored in memory)
- Historical decisions with rationale
- Resolved issues and solutions
- Pattern library
- Performance benchmarks
Always optimize for relevance over completeness. Good context accelerates work; bad context creates confusion.
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 an agent published in the GitHub repository echoVic/blade-code (180 stars, last pushed 4d ago), licensed MIT. It adds 43 tokens to every session and 370 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.
Other agents, from other repositories
Agent Prompt: Dream memory consolidation
Instructs an agent to perform a multi-phase memory consolidation pass — orienting on existing memories, gathering recent signal from logs and transcripts, merging updates into topic files, and pruning the index.
Demonstrate
Agent for demonstrating VS Code features.
playwright-test-generator
Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.
.NET-Notebook-Migration-Agent
Expert .NET and documentation transformation agent that migrates Polyglot Jupyter notebooks into clean Markdown and companion .NET sample code.
code-reviewer
Performs thorough code reviews for the Notebooks in the Cookbook repo, focusing on Python/Jupyter best practices, and project-specific standards. Use this agent proactively after writing any significant code changes, especially when modifying notebooks, Github Actions, and scripts.
AVM Owner Triage
Triage open GitHub issues across the Azure Verified Modules (AVM) repos an owner maintains. Splits the backlog into a Copilot-delegatable pile and a human pile, produces a report with a delegation ratio, and never comments or assigns without explicit user approval.
