context

context is a skill for Claude Code, Codex from escapeboy/ai-prompts. It costs 21 tokens per session (1,149 once invoked), scanned A, original, MIT.

A project-knowledge manager for Serena, a system that stores reusable notes about a codebase, such as its architecture and conventions.

In plain words
What is it for?
Use it to load, save, refresh, inspect, list, or clear stored project knowledge. It is intended for projects with reusable memories, not one-off edits.
Why use it?
It reduces repeated file reading and helps keep the agent's understanding of the project current across sessions.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

context 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 4d 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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/context — Memory & Context Management

Manages the Serena memory system that stores architectural knowledge, conventions, and project context. Loading memories at the start of a session saves 60-70% of tokens by eliminating repeated file reads.


When to Use This Skill (and When NOT to)

Use this skill for Use a simpler approach for
Starting a session on a project with existing memories — load before any code work A repo with no memories yet and one quick edit — just read the one file
Capturing durable architecture / conventions / deploy knowledge that outlives the session (save, create) An ephemeral session fact — let auto-memory / MEMORY.md hold it
Refreshing a memory after a major refactor so Claude stops making stale assumptions A memory touched days ago on an unchanged codebase — it's still current
Auditing what's loaded and what caching is buying you (inspect, list) A single-file lookup where symbolic exploration answers it directly

Start simple. Reach for this skill only when the project has (or clearly warrants) reusable memories — don't scaffold a memory set for a one-off task. Without Serena, use /optimize instead; it has fallback strategies.


Usage

/context [action] [name]

Quick Examples

/context load                    # Load all relevant memories for current project
/context list                    # Show all available memories
/context save architecture       # Create or update the architecture memory
/context refresh codebase-conventions  # Regenerate a stale memory
/context inspect                 # Show what's currently loaded + cache status
/context clear                   # Unload all memories from context

Actions

Compact dispatch below. For the full process steps, parameters, and output formats of any action, read references/actions.md.

Action What it does When to run
load Load core memories (architecture, codebase-conventions) + conditionally load module/testing/docker/deployment memories by task context Start of every session, before code work
list List all project memories with last-updated + load/cache status To see what's available
save [name] Gather context → structure as Markdown → write .serena/memories/[name].md After learning something durable worth persisting
refresh [name] Re-explore the code and overwrite an existing memory with current state After a major refactor, a new module, or a memory >2 weeks old
inspect Show loaded memories, token sizes, cache hit rate, and project/Serena/constitution status To audit context + caching
clear Unload all memories from the current conversation (does not delete files) Switching projects or context is stale
create [name] Interactive memory creation — asks what to document and how to structure it When you want to build a memory step by step

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 is a skill published in the GitHub repository escapeboy/ai-prompts (91 stars, last pushed 9d ago), licensed MIT. It adds 21 tokens to every session and 1,149 once invoked, about $0.0001 per session on Opus 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.
