Recall

What it does

When your agent uses it

• Decide something worth remembering about THIS project — an architecture fact
• A decision and its rationale
• A glossary term
• A useful discovery (X lives in Y

Example prompts

• “X lives in Y”
• “Z is generated”
• “/recall”

Requirements

• Python 3
• A credential in MC_API_TOKEN

What it can do on your machine

Read from SKILL.md and the folder at commit 92b91d0. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • curl

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • MC_API_TOKEN

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Recall loads about 1.5k tokens when it runs. Until then it costs about 221 tokens; SKILL.md has 619 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~221

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Save durable project knowledge to Mission Control's Recall (project memory) so future sessions start already knowing it, AND navigate this project's indexed code graph. Use when you discover or decide something worth remembering about THIS project — an architecture fact, a decision and its rationale, a convention, a stack detail, a glossary term, a known issue, or a useful discovery ("X lives in Y", "Z is generated"). Also use when you need to LOCATE or READ code — where a symbol is defined (and its verbatim source), what calls it, or what a change would impact — via the graph_search / graph_node / get_neighbors / impact_of / shortest_path MCP tools instead of grepping. Requires a Mission Control agent session (MC_API_URL, MC_API_TOKEN, MC_TASK_ID are injected automatically). Not for transient to-dos, run-specific notes, or projects running outside Mission Control.
