What it does
Recover Context is an agent skill from pchalasani/claude-code-tools. Extract full context of the last task from the most recent parent session shown in the session lineage. Strategically uses sub-agents to avoid bloating your own context.
Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Subagents. The repository describes itself as: Practical productivity tools for Claude Code, Codex-CLI, and similar CLI coding agents. The licence is MIT.
When your agent uses it
- Tasks that involve Subagents
Example prompts
- “/recover-context”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify the most recent parent session from the lineage chain (the last
- Use sub-agents to explore (to avoid bloating your own context)
- Extract the following from the most recent session
- Also check for associated documents
- Report back concisely
What it can do on your machine
Read from SKILL.md and the folder at commit bbb555c. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Recover Context loads about 544 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 240 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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
- Extract full context of the last task from the most recent parent session shown in the session lineage. Strategically uses sub-agents to avoid bloating your own context.
recover-context
Use this skill to extract context from a parent session when a session lineage is present (shown in the first user message of this conversation).
Instructions
Identify the most recent parent session from the lineage chain (the last file in the chronological list).
Use sub-agents to explore (to avoid bloating your own context):
- If you have the Task tool with subagent support, use the
session-searchersubagent (subagent_type:session-searcher) to analyze the most recent session - If sub-agents are NOT available, use the
aichat:session-searchskill instead
- If you have the Task tool with subagent support, use the
Extract the following from the most recent session:
- What was the last task being worked on?
- What was the current state of that task (completed, in-progress, blocked)?
- Any pending items or next steps mentioned?
- Key decisions made or approaches chosen
Also check for associated documents:
- Issue specs or task descriptions referenced in the session
- Any markdown files created during that session (check WORKLOG/, issues/, etc.)
- Code files that were being modified
Report back concisely:
- State your understanding of the task context
- List any files you found that are relevant
- Ask the user how they'd like to proceed
Example Sub-agent Prompt
If using the Task tool with session-searcher subagent:
Analyze the session file at [path from lineage] and extract:
1. The last task being worked on (look at the final 20-30 messages)
2. Current state of that task
3. Any referenced markdown files (issue specs, work logs, etc.)
4. Pending next steps or blockers
Return a concise summary.Constraints
- Do NOT read large session files directly into your own context
- ALWAYS delegate to sub-agents or the session-search skill
- Keep your summary concise - the user knows what they were working on
- Focus on the LAST task, not the entire session history
