1	# Embedded Data Parsing Libs
2
3	## Overview
4
5	Use this skill for small embedded data parsers where the main risks are memory allocation, input bounds, encoding assumptions, recursion, and callback handling. Cover `cJSON`, `jsmn`, and `inih` without copying their full APIs.
6
7	## When To Use
8
9	Use this skill when:
10
11	- The user wants to parse JSON or INI on an MCU.
12	- The task mentions `cJSON`, `jsmn`, `inih`, config files, telemetry JSON, command payloads, or settings parsing.
13	- The issue involves parse failure, memory leak, heap exhaustion, malformed input, callback mapping, or stack/recursion limits.
14
15	Do not use this skill for binary protocols or large streaming parsers outside these small libraries.
16
17	## First Questions
18
19	Ask for:
20
21	- Parser library: `cJSON`, `jsmn`, `inih`, or another small C parser.
22	- Input source and maximum input size.
23	- Runtime: bare metal, RTOS, Linux, bootloader, or shell command.
24	- Whether dynamic allocation is allowed.
25	- Expected schema and how malformed input should behave.
26	- Current error, sample input, and memory budget.
27
28	## Library Checks
29
30	### cJSON
31
32	- Decide whether heap allocation is acceptable.
33	- Provide custom malloc/free hooks if the project uses a custom allocator.
34	- Always delete parsed trees after use.
35	- Bound input size before parsing.
36	- Validate type before reading values.
37
38	### jsmn
39
40	- Allocate enough tokens for the expected JSON shape.
41	- Handle `JSMN_ERROR_NOMEM`, `JSMN_ERROR_INVAL`, and `JSMN_ERROR_PART`.
42	- Remember that tokens reference the original input buffer.
43	- Validate string lengths and value types manually.
44
45	### inih
46
47	- Implement the handler callback with strict section/key matching.
48	- Decide whether duplicate keys overwrite, error, or merge.
49	- Bound line length and input source.
50	- Validate converted numeric values and ranges.
51
52	## Common Failures
53
54	- Heap fragmentation from repeated `cJSON_Parse` without hooks or cleanup.
55	- Token buffer too small for `jsmn`.
56	- Using JSON token pointers after the input buffer is freed.
57	- Accepting partial config and booting with unsafe defaults.
58	- Silent typo in INI key because handler ignores unknown fields.
59
60	## Verification
61
62	Before claiming parser integration works:
63
64	- State parser, allocation policy, max input size, and schema assumptions.
65	- Test valid input, missing fields, wrong types, malformed input, and oversize input.
66	- Confirm memory is released or static buffers are bounded.
67	- Confirm unknown fields and duplicate keys behavior.
68
69	## Example
70
71	User:
72
73	```text
74	想用 cJSON 解析串口发来的配置。
75	```
76
77	Agent:
78
79	1. Asks for max payload size, schema, allocator policy, and malformed-input behavior.
80	1. Uses custom hooks if needed and validates each field type.
81	1. Tests good JSON, missing keys, bad types, and oversized payloads.
