At a glance
Patch recipe that turns on Aider's --cache-prompts by default for models that support caching, with a verification procedure against the wire request.
- Works in 4 steps: Run aider --model… → Capture wire. → Request body should contain… → …
- Contributing a patch that enables prompt caching by default in Aider
- SKILL.md covers Target, Symptom, Fix and Verify, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The target is aider/args.py in the Aider repository, where the --cache-prompts flag is defined with default=False. Aider already implements the four-breakpoint Anthropic caching pattern correctly, but most users never see the benefit because they must know to enable it by flag, config file or environment variable.
The fix flips the default to True. A per-model cache_control setting in aider/models.py already stops caching from being sent to models that do not support it, so the change only moves caching from opt-in to opt-out. The recipe also asks for a CHANGELOG note.
To verify, run aider with claude-3-7-sonnet-20250219 and no cache flag or config entry, capture the request on the wire, and confirm the body carries an ephemeral cache_control marker at the four breakpoints for system, repo map, files and current message, and that the second turn reports cache_read_input_tokens above zero. The background argues the 1.25x cache-write premium is small and repaid after the second hit, and notes that Cline, Roo and OpenCode already default to caching.
When your agent uses it
- Contributing a patch that enables prompt caching by default in Aider
- Checking whether Aider requests actually carry cache_control markers
Example prompts
- “Make --cache-prompts default to on in Aider's args.py and add the CHANGELOG note.”
- “Verify that a plain Aider run with a Claude model sends cache_control on all four breakpoints.”
Requirements
- A checkout of the Aider repository
- An Anthropic model and API access for the wire check
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Run aider --model claude-3-7-sonnet-20250219 with NO mention of
- Capture wire.
- Request body should contain cache_control: {"type": "ephemeral"}
- Confirm 2nd-turn usage.cache_read_input_tokens > 0.
What it can do on your machine
Read from SKILL.md and the folder at commit 5b58ae2. 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 (its code samples are diff).
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
Aider Prompt Caching Default loads about 638 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 227 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 227 words (~638 tokens).
“aider/args.py in Aider-AI/aider. The --cache-prompts flag is defined here with default=False.”
