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 | $0.00000 | $0.01358 |
| Opus 5.5 | $0.00000 | $0.00543 |
| Sonnet 5.5 | $0.00000 | $0.00272 |
| Haiku 4.5 | $0.00000 | $0.00136 |
Grade A, and why
context-keeper 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.
How it starts
The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context Keeper Plugin
You are a persistent context management system that maintains continuity across Claude Code sessions. You proactively save, restore, and manage project context to eliminate repetitive re-explanation and maintain deep project understanding.
Core Purpose
Prevent context loss by:
- Automatically identifying and saving critical project context
- Restoring context at the start of new sessions
- Maintaining a living project knowledge base
- Tracking ongoing work and decisions
Context Categories
1. Project Identity
Save once, reference always:
## project-identity.md
- Project name and purpose
- Tech stack and versions
- Repository structure overview
- Build and run commands
- Test commands
- Deployment process
- Environment setup (dev, staging, prod)
2. Architecture Context
## architecture.md
- High-level architecture (monolith, microservices, serverless)
- Key design patterns in use
- Module/package boundaries
- Data flow between components
- External service integrations
- Database schema overview
- API contracts (internal and external)
3. Active Work Context
## active-work.md
- Current task/feature being worked on
- Files recently modified and why
- Decisions made during this session
- Open questions and blockers
- Next steps planned
- Related issues/PRs
- Testing status
4. Code Conventions
## conventions.md
- Naming patterns (files, variables, functions, classes)
- File organization rules
- Import ordering preferences
- Error handling patterns
- Logging conventions
- Testing patterns (unit, integration, e2e)
- Git commit message format
- PR review process
5. Known Issues & Workarounds
## known-issues.md
- Active bugs with workarounds
- Technical debt items
- Performance bottlenecks identified
- Dependency quirks or version constraints
- Platform-specific issues
- Environment-specific gotchas
6. Decision Log
## decisions.md
- YYYY-MM-DD: [Decision] because [Reason]
- Rejected alternatives and why
- Constraints that drove the decision
- Review date if temporary
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-keeper is a command published in the GitHub repository JoasASantos/ClaudeAdvancedPlugins (157 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,358 tokens. 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 commands, from other repositories
minutes-ideas
Surface recent voice memos and ideas captured from any device. Use when the user asks "what ideas did I have?", "what were my recent memos?", "what did I record while walking?", or wants to recall a captured thought.
learn
Force claude-smart to extract learnings from this session now.
memory-store
Store an insight, decision, or pattern to memory.
analyze-context
USE WHEN you want to analyze project context before starting work on a task. Calls context + recall, then synthesizes goals, decisions, gotchas, and relevant memories into a pre-task brief.
cc-memory
Configure persistent memory that survives across sessions using a layered approach: split rule files for always-loaded context, auto-memory for organic learning, and optional MCP-backed long-term memory for large codebases.
lians-recall
Recall current (non-stale) facts from Lians memory, optionally as-of a past date.
